Hapi - How to parse the payload to JSON? - json

Question

So I'm trying to study up on HTTP/TCP/IP Protocols, Nodejs, MongoJS,and MongoDB all at once. So I'm trying to figure out a couple things with the Hapi Web Framework. I am able to communicate with the server with my iOS simulator however, I can't seem to parse the payload right. I understand I could use parameters in the URL to send the information but I would like to use the payload.
So I end up with this being saved into Mongo.
(
{
"_id" = 5431f161bb859872034d2456;
"{\"userLastNameKey\":\"Kwon\",\"userEmailKey\":\"email\",\"userFirstNameKey\":\"Michael\",\"userUsernameKey\":\"username\",\"userPasswordKey\":\"password\"}" = "";
},
{
"_id" = 5431fe5694ed4721046c1f8c;
"{\"userLastNameKey\":\"Kwon2\",\"userEmailKey\":\"email2\",\"userFirstNameKey\":\"Michael2\",\"userUsernameKey\":\"username2\",\"userPasswordKey\":\"password2\"}" = "";
This is my hapi code for the call.
// This will add a new user to the database
function addUser(request, response){
db.usersCollection.save(request.payload, function (err, saved){
if(err || !saved)
{
console.log("User not saved");
} else
{
console.log("User saved");
}
});
}
My end result I would like to try and get it to be like this
(
{
"_id" = 5431f161bb859872034d2456,
"userLastNameKey" = "Kwon",
"userEmailKey" = "email",
"userFirstNameKey"= "Michael",
"userUsernameKey" = "username",
"userPasswordKey" = "password",
}
)
Here's the iOS code
NSDictionary *userData = [User userToDictionary: newUserInfo];
NSData *userJSON = [NSJSONSerialization dataWithJSONObject: userData options: 0 error: nil];
NSURL *url = [NSURL URLWithString: urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: url];
[request setHTTPMethod: #"POST"];
[request addValue: #"application/json" forHTTPHeaderField: #"Content-Type"];
// This will set up the url session
NSURLSessionConfiguration* config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration: config];
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest: request fromData: userJSON completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if(error)
{
} else
{
}
}];
[uploadTask resume];
}
Anyone know how I can achieve this?

{
"_id" = 5431f161bb859872034d2456;
"userLastNameKey" = "Kwon";
"userEmailKey" = "email";
"userFirstNameKey"= "Michael";
"userUsernameKey" = "username";
"userPasswordKey" = "password";
}
That is NOT a JSON object. You need to use commas instead of semicolons. and colons instead of equals. Your ID is also not a decimal number so it's probably best to make it a string.
Your object would look like :
{
"_id" : "5431f161bb859872034d2456",
"userLastNameKey" : "Kwon",
"userEmailKey" : "email",
"userFirstNameKey" : "Michael",
"userUsernameKey" : "username",
"userPasswordKey" : "password"
}
To parse a (well-formatted) JSON string, use : var JSONObject = JSON.parse(JSONstring);
