I am using AFNetworking 2.0 to send data to my API (json). Everything works fine except of sending data with german letters like ä ü ö .
Does anyone know what is the problem?. The problem is not the API because i did it in Android and it worked.
Here is my code:
- (void)createItem:(MyItem*)newItem image:(UIImage*)image complete:(void (^)(NSInteger responsecode, NSString *hash, NSDictionary *reason))completeBlock {
NSData *imageData = [NSData new];
if(image != nil) {
imageData = UIImageJPEGRepresentation(image, 0.5);
}
NSMutableDictionary *parameters = [[NSMutableDictionary alloc]initWithCapacity:2];
[parameters newItem.address forKey:#"address"];
[parameters newItem.email forKey:#"email"];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
AFHTTPRequestOperation *op = [manager POST:postUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:#"photo" fileName:#"photo.jpg" mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *hash = operation.responseString;
completeBlock([operation.response statusCode], hash, nil);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
completeBlock([operation.response statusCode], nil, nil);
}];
[op start];
}

Using Postman on my Mac I have confirmed GET/POST works to my endpoint. On my iPad I am trying to do the same thing but only GET connects and returns data (just for
testing).
In Postman I have key of devices and value of [{"name":"1","values":[121,182,243]}]
From Postman I can Send and the physical object responds and the server returns an array of all devices and nothing else (which I do not require but that is how it goes). Postman does have x-www-form-urlencoded under Body. This works as expected from Postman.
From my iPad the following code always returns an error 400 which I think means I am providing something the server is not expecting.
+(void)makeRequest {
NSError *error = nil;
storedURL = [[NSUserDefaults standardUserDefaults] objectForKey:#"eb-ipaddress-saved"];
NSString *urlstring = [NSString stringWithFormat:#"http://%#",storedURL];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlstring] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSString *jsonPostBody = #"{\"devices\":[{\"name\":\"1\",\"values\":[121,182,243]}]}";
NSData *postData = [jsonPostBody dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:#"%lu",(unsigned long)[postData length]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
if(httpResponse.statusCode == 200)
{
NSError *parseError = nil;
NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:data options:0 error:&parseError];
NSLog(#"The response is - %#",responseDictionary);
NSInteger success = [[responseDictionary objectForKey:#"success"] integerValue];
if(success == 1)
{
NSLog(#"SUCCESS");
}
else
{
NSLog(#"FAILURE");
}
}
else
{
NSLog(#"Error");
}
}];
[dataTask resume];
}
My 4 logs from above (removed for clarity) return:
urlstring http://192.168.90.55:3000/dmx/set
jsonPostBody {"devices":[{"name":"1","values":[121,182,243]}]}
httpResponse 400
Error
I will eventually switch to variables in my POST when in production.
Thank you
Thanks to Larme's answer I used the code from Postman and that worked.
+(void)makeRequest
{
dispatch_semaphore_t sema = dispatch_semaphore_create(0);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://192.168.90.55:3000/dmx/set"]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:10.0];
NSDictionary *headers = #{
#"Content-Type": #"application/x-www-form-urlencoded"
};
[request setAllHTTPHeaderFields:headers];
NSMutableData *postData = [[NSMutableData alloc] initWithData:[#"devices=[{\"name\":\"1\",\"values\":[121,182,243]}]" dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postData];
[request setHTTPMethod:#"POST"];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (error) {
NSLog(#"%#", error);
dispatch_semaphore_signal(sema);
} else {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
NSError *parseError = nil;
NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:data options:0 error:&parseError];
NSLog(#"%#",responseDictionary);
dispatch_semaphore_signal(sema);
}
}];
[dataTask resume];
dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
}
I am trying to send a JSON request with AFNetworing but following code giving me JSON text did not start with array or object and option to allow fragments not set error:
NSString *post = [[NSString alloc] initWithFormat:
#"{\"request\":\"login\",\"userName\":\"%#\",\"password\":\"%#\"}", userName, password];
NSData *parameters = [post dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *parameterDictionary =
[NSJSONSerialization JSONObjectWithData:parameters options:NSJSONReadingAllowFragments error:nil];
DDLogDebug(#"Data: %#", [parameterDictionary description]);
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
AFHTTPRequestOperation *operation =
[manager POST:WEB_SERVICE_URL parameters:parameterDictionary
success:^(AFHTTPRequestOperation *operation, id responseObject) {
DDLogDebug(#"LoginView - Success Response: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
DDLogError(#"LoginView - Error Response: %#", [error description]);
}];
[operation start];
This is the log output of the parameterDictionary object:
{
password = q;
request = login;
userName = q;
}
I have looked similar questions for the error and tried to put parameters object in to an array but this time I got the error "Invalid type in JSON write (NSConcreteMutableData)"
NSMutableArray *array = [NSMutableArray new];
[array addObject:parameterDictionary];
DDLogDebug(#"Data: %#", [parameterDictionary description]);
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
AFHTTPRequestOperation *operation =
[manager POST:WEB_SERVICE_URL parameters:array
success:^(AFHTTPRequestOperation *operation, id responseObject) {
DDLogDebug(#"LoginView - Success Response: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
DDLogError(#"LoginView - Error Response: %#", [error description]);
}];
What I am doing wrong?
UPDATE:
I have tried following but it did't work:
NSMutableDictionary *dictionary = [NSMutableDictionary new];
[dictionary setObject:#"login" forKey:#"request"];
[dictionary setObject:#"q" forKey:#"userName"];
[dictionary setObject:#"q" forKey:#"password"];
DDLogDebug(#"Dictionary: %#", [dictionary description]);
DDLogDebug(#"Json: %#", [dictionary JSONRepresentation]);
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
AFHTTPRequestOperation *operation =
[manager POST:WEB_SERVICE_URL parameters:dictionary
success:^(AFHTTPRequestOperation *operation, id responseObject) {
DDLogDebug(#"LoginView - Success Response: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
DDLogError(#"LoginView - Error Response: %#", [error description]);
}];
UPDATE 2:
This what my AFHTTPRequestOperation look like on error block:
<AFHTTPRequestOperation: 0x7fd881fa1200, state: isFinished, cancelled: NO request: <NSMutableURLRequest: 0x7fd881f9fd60> { URL: http://www.olcayertas.com/services.php }, response: <NSHTTPURLResponse: 0x7fd881d913b0> { URL: http://www.olcayertas.com/services.php } { status code: 200, headers {
Connection = close;
"Content-Length" = 1050;
"Content-Type" = "application/json; charset=utf-8";
Date = "Wed, 21 Jan 2015 10:28:45 GMT";
Server = Apache;
"X-Powered-By" = PleskLin;
} }>
The JSON does not seem to validate on JSONlint.com. I would make sure the JSON is correct from there first.
This is what I entered:
{\"request\":\"login\",\"userName\":\"%#\",\"password\":\"%#\"}
I use this to check the JSON:
if ([NSJSONSerialization isValidJSONObject:requestJSONContents]) { }
I have solved the problem by checking my web service in browser. The problem was in my services.php file. There was an error about log file creation and this error was returning a non JSON response that causing the request to fail. My complate working code is here:
NSMutableDictionary *dictionary = [NSMutableDictionary new];
[dictionary setObject:#"login" forKey:#"request"];
[dictionary setObject:#"q" forKey:#"userName"];
[dictionary setObject:#"q" forKey:#"password"];
DDLogDebug(#"Dictionary: %#", [dictionary description]);
DDLogDebug(#"Json: %#", [dictionary JSONRepresentation]);
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
[manager setResponseSerializer:[AFJSONResponseSerializer serializer]];
//[manager.securityPolicy setAllowInvalidCertificates:true];
AFHTTPRequestOperation *operation =
[manager POST:WEB_SERVICE_URL parameters:dictionary
success:^(AFHTTPRequestOperation *operation, id responseObject) {
DDLogDebug(#"LoginView - Success Response: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
DDLogError(#"LoginView - Error Response: %#", [error description]);
DDLogError(#"Error: %#",operation);
}];
[operation start]
And here is my complate services.php file to make it as a complate example for passing and getting JSON with AFNetworiking and PHP service:
PHP web service that accepts JSON input and return JSON response
I am using AFNetworking 2.0, in this I have to pass json object in body part, How to pass HTTP Body in AFHTTPRequestOperationManager.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = #{#"foo": #"bar"};
NSURL *filePath = [NSURL fileURLWithPath:#"file://path/to/image.png"];
[manager POST:#"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileURL:filePath name:#"image" error:nil];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
Thanks,
Chatting with you offline, it sounds like the main concern is how to send profile image, name, email address, userid, and password in single request. It might look like:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSURL *filePath = ...
[manager POST:#"http://example.com/registration.json" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileURL:filePath name:#"image" error:nil];
[formData appendPartWithFormData:[name dataUsingEncoding:NSUTF8StringEncoding] name:#"name"];
[formData appendPartWithFormData:[email dataUsingEncoding:NSUTF8StringEncoding] name:#"email"];
[formData appendPartWithFormData:[userid dataUsingEncoding:NSUTF8StringEncoding] name:#"userid"];
[formData appendPartWithFormData:[password dataUsingEncoding:NSUTF8StringEncoding] name:#"password"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
No JSON is needed.
If you wanted to use JSON, you can do that, but you wouldn't use the constructingBodyWithBlock method (which creates a multipart/form-data request). Instead, you'd just create a plain old JSON request, e.g.:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
NSDictionary *parameters = #{
#"name" : name,
#"email" : email,
#"userid" : userid,
#"password" : password,
#"image" : base64EncodedImage
};
[manager POST:#"http://example.com/registration.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
Clearly, these are very different approaches, so whatever approach you adopt requires that the server code be written to handle the same API.
[Solved]
I'm trying to edit AFHTTPClient.m to make it work with POST Method in
-(NSMutableURLRequest *)requestWithMethod:(NSString *)method
path:(NSString *)path
parameters:(NSDictionary *)parameters
like this :
if ([method isEqualToString:#"GET"] ||[method isEqualToString:#"POST"] || [method isEqualToString:#"HEAD"] || [method isEqualToString:#"DELETE"])
I have problem with POST method with params userDevice ,I have function subclass from AFHTTPClient like this
EDIT:
I used different method like this but same result
-(void)loginWithEmail:(NSString *)email password:(NSString *)passwords
{
NSString *baseurl = #"http://localhost.com:9000/";
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:baseurl]];
[httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
[httpClient setDefaultHeader:#"Accept" value:#"application/json"];
[httpClient setAuthorizationHeaderWithUsername:email password:passwords];
and then this is my params :
NSDictionary *data = [NSDictionary dictionaryWithObjectsAndKeys:
model, #"deviceModel",
systemVersion, #"deviceVersion",
[NSNumber numberWithBool:0], #"productionMode",
appVersion, #"appVersion",
deviceType,#"deviceType", nil];
NSError *error = nil;
NSDictionary* jsonObject = [NSDictionary dictionaryWithObjectsAndKeys:data, #"userDevice", nil];
NSData *jsonLogin =[NSJSONSerialization dataWithJSONObject:jsonObject options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonLoginString = [[NSString alloc] initWithData:jsonLogin encoding:NSUTF8StringEncoding];
NSLog(#"JSON LOGIN OUTPUT :%#", jsonLoginString);
[httpClient setParameterEncoding:AFJSONParameterEncoding];
I request using this code :
NSMutableURLRequest *request = [httpClient requestWithMethod:#"POST"
path:#"/ios/login"
parameters:[NSDictionary dictionaryWithObjectsAndKeys:jsonLoginString,#"userDevice", nil]
];
AFJSONRequestOperation *operation = nil;
operation = [AFJSONRequestOperation
JSONRequestOperationWithRequest:request
success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSLog(#"Response : %#", request);
NSLog(#"JSON: %#",JSON);
}
failure:^(NSURLRequest *request , NSHTTPURLResponse *response, NSError *error , id JSON ){
NSLog(#"error: %#", error);
}];
[operation start];
this is the example json that I wanted :
"userDevice" : {
"appVersion" : "1.0",
"deviceModel" : "iPhone Simulator",
"productionMode" : false,
"deviceType" : "iPhone Simulator",
"deviceVersion" : "6.1"
}
am I missing something?
I am facing 1 problem while using AFJSONRequestOperation. My API Client is as follows
#import <Foundation/Foundation.h>
#import "AFHTTPClient.h"
#import "AFJSONRequestOperation.h"
#interface MyAPIClient : AFHTTPClient
+ (MyAPIClient *)sharedAPIClient;
#end
// .m file
#import "MyAPIClient.h"
#implementation MyAPIClient
+ (MyAPIClient *)sharedAPIClient {
static MyAPIClient *sharedClient = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedClient = [[MyAPIClient alloc] initWithBaseURL:[NSURL URLWithString:kBASE_URL]];
});
return sharedClient;
}
- (id)initWithBaseURL:(NSURL *)url {
self = [super initWithBaseURL:url];
if (!self) {
return nil;
}
[self registerHTTPOperationClass:[AFJSONRequestOperation class]];
[self setDefaultHeader:CONTENT_TYPE_FIELD value:CONTENT_TYPE_JSON_VALUE];
self.parameterEncoding = AFJSONParameterEncoding;
return self;
}
#end
Now when I request with following code it returns me "null" response
NSDictionary *params = [[NSDictionary alloc]initWithObjectsAndKeys:userName,#"email",password,#"password",nil];
NSMutableURLRequest *request = [[MyAPIClient sharedAPIClient] requestWithMethod:#"POST" path:#"login" parameters:params];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON)
{
NSDictionary *dictResponse = (NSDictionary*)JSON;
DLog(#"Login Success JSON: %#",JSON);
if (block) {
block(YES,nil);
}
}failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
DLog(#"Login Error:- %#",error);
if (block) {
block(NO,error);
}
}];
[operation start];
But when I use AFHTTPRequestOperation it reurns me correct output with logged in used info
NSURL *loginUrl = [NSURL URLWithString:kBASE_URL];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:loginUrl];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
userName,#"email",password,#"password",nil];
NSMutableURLRequest *request = [httpClient requestWithMethod:#"POST" path:#"login" parameters:params];
//Notice the different method here!
AFHTTPRequestOperation *operation = [httpClient HTTPRequestOperationWithRequest:request
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"Raw data Response: %#", responseObject);
NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
NSLog(#"Converted JSON : %#", jsonArray);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error){
NSLog(#"Error: %#", error);
}];
//Enqueue it instead of just starting it.
[httpClient enqueueHTTPRequestOperation:operation];
My server returns JSON response.
What is the problem in above code? Why AFJSONRequestOperation returns null response while
AFHTTPRequestOperation returns me correct response ? Any kind of help is appreciated. Thanks in advance
