Android - HttpClient JSON POST with Basic Authentication

Question

I am trying to implement a simple JSON post to the URL that accepts JSON in body with basic authentication on ANDROID.

I have tried with HttpUrlConnection but I get "unauthorized" and my data gets send to the server.

Another way I tried is using HttpClient, but now I get a different problem. Authentication works perfect but the data is not sent to the server...

Just to be sure, I setup a small test in a simple Java project (not Android Environment).

This is the code that I am using to POST to the server:

DefaultHttpClient httpClient = new DefaultHttpClient();
ResponseHandler<String> resonseHandler = new BasicResponseHandler();
HttpPost postMethod = new HttpPost("http://localhost/api/v1/purchase/");    
postMethod.setEntity(new StringEntity("{\"amount_adult\" : 1, \"object_id\" : 13}"));
postMethod.setHeader( "Content-Type", "application/json");
String authorizationString = "Basic " + Base64.encodeToString(("travelbuddy" + ":" + "travelbuddy").getBytes(), Base64.DEFAULT); //this line is diffe
postMethod.setHeader("Authorization", authorizationString);
String response = httpClient.execute(postMethod,resonseHandler);
System.out.println("response :" + response);

The code in the Java project works perfect.

When I try exact same code in Android, I get internal server error from the server, which means that JSON data has not been received.

I really don't understand why this is working in JAVA but not in Android.

The effect that I would like to achieve, is the following command:

curl --dump-header - -H "Content-Type: application/json" -X
POST --data '{"amount_adult":1, "object_id":13}' 
--user travelbuddy:travelbuddy http://localhost/api/v1/purchase/

Answer 1

String authorizationString = "Basic " + Base64.encodeToString(
    ("travelbuddy" + ":" + "travelbuddy").getBytes(),
    Base64.DEFAULT);

...

The solution is a bit simpler actually:

    String authorizationString = "Basic " + Base64.encodeToString(
        ("travelbuddy" + ":" + "travelbuddy").getBytes(),
        Base64.NO_WRAP); // <=== Do not add '\n'

Answer 2

Finally, everything is sorted. Anyone that might experience this problem following is the solution.

String authorizationString = "Basic " + Base64.encodeToString(("travelbuddy" + ":" + "travelbuddy").getBytes(), Base64.DEFAULT); //this line is diffe
postMethod.setHeader("Authorization", authorizationString);

This Base64.encodeToString appends an extra "\n" to the end of the authorization string. Then on the server next line after "\n" character is treated as body of the request and of course incorrect.

By replacing all new lines in authorization string will solve the issue:

    String authorizationString = "Basic " + Base64.encodeToString(("travelbuddy" + ":" + "travelbuddy").getBytes(), Base64.DEFAULT); //this line is diffe
authorizationString.replace("\n", "");
    postMethod.setHeader("Authorization", authorizationString);

Easy fix but hard to find ;-)
