I have a application that need to communicate with another application.
In the first application I mentioned it as:
public List<ContactsBO> getZingyContactsByCompanyId(int companyId) throws Exception {
String url="http://localhost:8080/ZingyApp/getContactsToBSAByAccountId";
URL object=new URL(url);
JSONObject account = new JSONObject();
String accountId = "58fd8c58abced355f69bf0bb";
account.put("accountId", accountId);
HttpURLConnection conn = (HttpURLConnection) object.openConnection();
conn.setConnectTimeout(50000);
conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
OutputStream os = conn.getOutputStream();
OutputStreamWriter wr = new OutputStreamWriter(os);
wr.write(account.toString());
wr.flush();
os.close();
String json_response = "";
BufferedReader br = null;
if (conn.getResponseCode() == 200) {
br = new BufferedReader(new
InputStreamReader(conn.getInputStream()));
} else {
br = new BufferedReader(new
InputStreamReader(conn.getErrorStream()));
}
String text = "";
while ((text = br.readLine()) != null) {
json_response += text;
}
String contacts = json_response;
System.out.println("Contacts:"+contacts);
return null;
}
In second application I am trying to get the parameter accountId, which I set to a JSON object.
#RequestMapping(value="/getContactsToBSAByAccountId",method=RequestMethod.POST)
public #ResponseBody List<Contacts> getContactsByAccountId(#ModelAttribute("accountId") String accountId) {
System.out.println("Inside Account Details:"+accountId);
List<Contacts> contacts=salesContactService.getContactsByAccountId("58fd8c58abced355f69bf0bb");
return contacts;
}
Here accountId is null.
When I changed #RequestParams, the method itself is not getting called, and I got 400 error, when I change to #ModelAttribute only it gets called but values are not getting post.
Can someone give a suggestion on this one?
#RequestBody Map objectMap instead of ModelAttribute and get from map like String accountId = (String)objectMap.get("accountId")
This worked for me.

I would like to work on moving the json data from libgdx to my web server, but I am not sure how to do it. The method below was created by referring to libgdx's documentation.
private void httpPostJson(){
final Json json = new Json();
final String requestJson = json.toJson(requestObject);
Net.HttpRequest request = new Net.HttpRequest("POST");
final String url = "http://localhost:8080/data";
request.setUrl(url);
request.setContent(requestJson);
request.setHeader("Content-Type", "application/json");
Gdx.net.sendHttpRequest(request, new Net.HttpResponseListener() {
#Override
public void handleHttpResponse(Net.HttpResponse httpResponse) {
String responseJson = httpResponse.getResultAsString();
Gson gson = new Gson();
data = gson.fromJson(responseJson, Person.class);
//'Person' is just sample class. data is class Person's object.
data.StoreData("",1);//successed to receive json data from web server.
//StoreData is just getter method.
}
#Override
public void failed(Throwable t) {
Gdx.app.log("failed!");
}
#Override
public void cancelled() {
Gdx.app.log("cancelled!");
}
});
}
It is possible to receive data transmitted from a web server.
But, this method can't send data to web server.
Can you tell me how to move data from libgdx project to web server?
This is the data transmitted to the web server:
final String requestJson = json.toJson(requestObject);
We are using the following Code (as you have more control over the request as opposed to using gdx.net), works like a charm, just don't execute on the main thread - body is your JSON as String
URL url = new URL(<your url>);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty("Content-Type",
"application/json; charset=utf-8");
if (body != null) {
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(
os, "UTF-8"));
writer.write(body);
writer.close();
os.close();
}
conn.connect();
String s = stringFromStream(conn.getInputStream(), 4096);
Method stringFromStream:
public static String stringFromStream(final InputStream is,
final int bufferSize) {
final char[] buffer = new char[bufferSize];
final StringBuilder out = new StringBuilder();
try {
final Reader in = new InputStreamReader(is, "UTF-8");
try {
for (; ; ) {
int rsz = in.read(buffer, 0, buffer.length);
if (rsz < 0)
break;
out.append(buffer, 0, rsz);
}
} finally {
in.close();
}
} catch (Exception ex) {
}
return out.toString();
}
Using JAVA, I am trying to republish a dashboard to a particular User. It returns me HTTP status 500. Below is the code for it.
String sisenseURL = surl; // This is correct URL to POST API for PUBLISH
String urlParameters = "force=true";
byte[] postData = urlParameters.getBytes( StandardCharsets.UTF_8 );
int postDataLength = postData.length;
URL url = new URL( sisenseURL );
HttpURLConnection conn= (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setInstanceFollowRedirects(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty("Content-Length", Integer.toString(postDataLength ));
conn.setRequestProperty("Authorization", accessToken);
conn.setUseCaches(false);
try(DataOutputStream wr = new DataOutputStream(conn.getOutputStream())) {
wr.write( postData );
}
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
final StringBuffer stringBuffer = new StringBuffer();
String line;
while ((line = in.readLine()) != null) {
stringBuffer.append(line);
}
in.close();
The request runs file with POSTMAN as well as with the Swagger UI for Sisense.
Any help would be greatly appreciated.
TIA

Here is a java example for sisense V6.7 of updating dashboard shares using the rest API
You didnt share your payload so not sure if thats the problem, but the example below worked for me.
I took the sendPostRequest code from here
import java.io.*;
import java.net.*;
public class Runner {
public static void main(String[] args){
try {
//Dashboard shares payload
String payload = "{\"sharesTo\":[{\"shareId\":\"58504c5221785b627cb4361d\",\"type\":\"user\",\"subscribe\":false},{\"shareId\":\"58505ba6ec4df9701a000019\",\"type\":\"user\",\"rule\":\"view\",\"subscribe\":false}]}";
String str = sendPostRequest(getDashboardUrl(), payload);
System.out.println("Done");
}
catch (RuntimeException e){
}
}
public static String sendPostRequest(String requestUrl, String payload) {
try {
URL url = new URL(requestUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
connection.setRequestProperty("Authorization", getAuthorization());
OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
writer.write(payload);
writer.close();
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuffer jsonString = new StringBuffer();
String line;
while ((line = br.readLine()) != null) {
jsonString.append(line);
}
br.close();
connection.disconnect();
return jsonString.toString();
} catch (Exception e) {
throw new RuntimeException(e.getMessage());
}
}
public static String getDashboardUrl(){
//Sisense domain
String baseURL = "http://localhost:8081";
return baseURL + "/api/shares/dashboard/5850511cec4df9701a000013";
}
public static String getAuthorization(){
return "Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyIjoiNTg1MDRjNTIyMTc4NWI2MjdjYjQzNjFkIiwiYXBpU2VjcmV0IjoiOGUwZDIyOWItY2VmMS0xYTE4LTNhYWEtYmY1ZmE1ZmNkNTExIiwiaWF0IjoxNTE1MDEzMzkxfQ.zgx0Nv8YztfM2rm5WTCnJ0R6C_n5V-HNkEZgAcINfs4";

I'm using Apache HTTPClient 4.5.3 to make some HTTP requests, but I am getting a g-zipped response I have tried many things I found online but non of them worked. I still get gibberish when I print the response. Below are the relevant code. What do I need to do to get a human readable response?
static public CloseableHttpClient CreateHttpClient() {
// return
// HttpClients.custom().disableAutomaticRetries().setHttpProcessor(HttpProcessorBuilder.create().build())
// .build();
return HttpClientBuilder.create().disableAutomaticRetries()
.setHttpProcessor(HttpProcessorBuilder.create().build()).build();
}
static public RequestConfig GetConfig() {
return RequestConfig.custom().setSocketTimeout(READTIMEOUT).setConnectTimeout(CONNECTTIMEOUT)
.setConnectionRequestTimeout(REQUESTTIMEOUT).build();
}
static public String updates() {
String result = "";
String url = "https://example.com";
CloseableHttpClient httpClient = CreateHttpClient();
CloseableHttpResponse response = null;
URL urlObj;
RequestConfig config = GetConfig();
try {
urlObj = new URL(url);
HttpPost request = new HttpPost(url);
request.setConfig(config);
StringEntity params = new StringEntity("example");
request.addHeader("Accept-Language", "en");
request.addHeader("Content-Type", "application/json; charset=UTF-8");
request.addHeader("Content-Length", String.valueOf(params.getContentLength()));
request.addHeader("Host", urlObj.getHost());
request.addHeader("Connection", "Keep-Alive");
request.addHeader("Accept-Encoding", "gzip");
request.setEntity(params);
response = httpClient.execute(request);
int responseCode = response.getStatusLine().getStatusCode();
System.out.println("updates response code: " + responseCode);
// BufferedReader rd = new BufferedReader(new
// InputStreamReader(response.getEntity().getContent(), "UTF-8"));
result = EntityUtils.toString(response.getEntity());
// String line = "";
// while ((line = rd.readLine()) != null) {
// result.append(line);
// }
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (response != null)
response.close();
httpClient.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return result;
}
You should get the content from the response entity which is an InputStream. Than you could create a String from that InputStream with BufferedReader
HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
String result = convertInputStreamToString(instream);
instream.close();
}
Write your own convertInputStreamToString. If you need help for doing that check here:
Read/convert an InputStream to a String
Is there any way to convert this code into URLCOnnection instead of using Httpclient ? Im using API23 and HTTP CLient is not supported anymore. I have a hard time using URLCOnnection because almost all the tutorials uses HttpClient for connection. thanks

This is the basic format for URLConnection that I merged from some working code of mine with yours. If you fill in your code where I've specified, it should work.
//-------------------
String username = (String)arg0[0];
String password = (String)arg0[1];
String link = "http://myphpmysqlweb.hostei.com/login.php?username="+username+"& password="+password;
InputStream is = null;
try {
URL url = new URL(link);
URLConnection urlConnection = (HttpURLConnection) url.openConnection();
is = urlConnection.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
//FILL IN YOUR CODE HERE!
//FILL IN YOUR CODE HERE!
} catch(Exception e){
return new String("Exception: " + e.getMessage());

I want to retrieve some data from mysql in php and store it in array and then in Android I want to use that data. For example I want to retrieve the location of multiple people whose profession id = 1 (let's say) and then in Android I want to show that locations on map. I don't know how to do this. I have the following PHP and Android files which don't work. Please help.
<?php

Dear imdad: The Problem lies in you json file.
{"[]":{"user_id":"77","crtloc_lat":"34.769638","crtloc_lng":"72.361145"}, {"user_id":"76","crtloc_lat":"34.769604","crtloc_lng":"72.361092"},{"user_id":"87","crtloc_lat":"33.697117","crtloc_lng":"72.976631"}}
The Object is empty give it some name like here is response. Change it as:
{"response":[{"user_id":"77","crtloc_lat":"34.769638","crtloc_lng":"72.361145"},{"user_id":"76","crtloc_lat":"34.769604","crtloc_lng":"72.361092"},{"user_id":"87","crtloc_lat":"33.697117","crtloc_lng":"72.976631"}]}
