how to get response body in okhttp when code is 401

问题:

i am using okHttp 3.2.0 and here is code for building request object

MediaType JSON = MediaType.parse(AppConstants.CONTENT_TYPE_VALUE_JSON); RequestBody body = RequestBody.create(JSON, requestBody);       HttpUrl url = new HttpUrl.Builder()                                     .scheme("http")                                     .host("192.168.0.104")                                     .port(8080)                                     .addPathSegment("mutterfly-server")                                     .addPathSegment("j_spring_security_check")                                     .addQueryParameter("j_username", jsonObject.getString("emailId"))                                     .addQueryParameter("j_password", jsonObject.getString("password"))                                     .build();       request = new Request.Builder()                                     .addHeader(AppConstants.CONTENT_TYPE_LABEL, AppConstants.CONTENT_TYPE_VALUE_JSON)                                     .addHeader(AppConstants.ACCEPT_LABEL, AppConstants.CONTENT_TYPE_VALUE_JSON)                                     .url(url)                                     .post(body)                                     .build(); 

And here is how i parse the response

client.newCall(request).enqueue(new Callback() {                 @Override                 public void onFailure(Call call, IOException e) {                  }                  @Override                 public void onResponse(Call call, final Response response) throws IOException {                      String respBody;                     if (response.isSuccessful()) {                         if (response.body() != null) {                             respBody = response.body().string();                             Log.i(TAG, respBody);                             response.body().close();                             if (AppMethods.checkIfNull(loginParserListener)) {                                 try {                                     final VUser user = AppMethods.getGsonInstance().fromJson(respBody, VUser.class);                                 } catch (Exception e) {                                  }                             }                         }                     } else {                          switch (response.code()){                             case 401:                                 String body="HTTP_UNAUTHORIZED";                                 break;                         }                     }                 }             }); 

This is the ideal response(from web rest client) when authentication is failed.

{"msgDesc":"The username or password you entered is incorrect..","statusCode":401} 

EDIT:

response.toString() returns

Response{protocol=http/1.1, code=401, message=Unauthorized, url=http://192.168.0.104:8080/mutterfly-server/j_spring_security_check?j_username=s@s.s&j_password=1} 

response.body().toString() returns

okhttp3.internal.http.RealResponseBody@528ae030 

i want to fetch the 'msgDesc' which is in response body. is there any method which will return this string?

回答1:

Try this:

switch (response.code()){         case 401:            JsonObject object=new JsonObject(response.body().string());            String body=object.getString("msgDesc");            break; } 

回答2:

It's quite weird but Square, the company behind OkHttp, has chosen to not use 'toString()' but 'string()' as method for getting the body as a String.

So this works;

String string = response.body().string(); //convert to JSON and get your value 

But this doesn't:

String string = response.body().toString(); 

回答3:

401 means permission denied.

Check if your token is valid or user/password is correct.
