OkHttp Post Body as JSON

OkHttp Post Body as JSON

---

그래서 Koush의 Ion을 사용했을 때 간단한 방법으로 게시물에 json 본문을 추가 할 수있었습니다. .setJsonObjectBody(json).asJsonObject()

OkHttp로 넘어 가고 있는데 정말 좋은 방법을 찾지 못했습니다. 여기저기서 오류 400이 발생합니다.

누구나 아이디어가 있습니까?

나는 심지어 수동으로 그것을 json 문자열로 형식화하려고 시도했습니다.

String reason = menuItem.getTitle().toString();
JsonObject json = new JsonObject();
json.addProperty("Reason", reason);

String url = mBaseUrl + "/" + id + "/report";

Request request = new Request.Builder()
        .header("X-Client-Type", "Android")
        .url(url)
        .post(RequestBody
                .create(MediaType
                    .parse("application/json"),
                        "{\"Reason\": \"" + reason + "\"}"
                ))
        .build();

client.newCall(request).enqueue(new com.squareup.okhttp.Callback() {
    @Override
    public void onFailure(Request request, IOException throwable) {
        throwable.printStackTrace();
    }

    @Override
    public void onResponse(Response response) throws IOException {
        if (!response.isSuccessful()) throw new IOException(
                "Unexpected code " + response);
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(context, "Report Received", Toast.LENGTH_SHORT).show();
            }
        });
    }
});

/*Ion.with(getContext(), url)
        .setHeader("X-Client-Type", "Android")
        .setJsonObjectBody(json)
        .asJsonObject()
        .setCallback(new FutureCallback<JsonObject>() {
            @Override
            public void onCompleted(Exception e, JsonObject result) {
                Toast.makeText(context, "Report Received", Toast.LENGTH_SHORT).show();
            }
        });*/

편집 : 나중에이 질문에 걸려 넘어지는 사람을 위해 모든 것을 비동기 적으로 수행하는 솔루션이 있습니다. 선택한 답변이 정확하지만 내 코드가 약간 다릅니다.

String reason = menuItem.getTitle().toString();
if (reason.equals("Copyright"))
    reason = "CopyrightInfringement";
JsonObject json = new JsonObject();
json.addProperty("Reason", reason);

String url = mBaseUrl + "/" + id + "/report";

String jsonString = json.toString();
RequestBody body = RequestBody.create(JSON, jsonString);

Request request = new Request.Builder()
    .header("X-Client-Type", "Android")
    .url(url)
    .post(body)
    .build();

client.newCall(request).enqueue(new com.squareup.okhttp.Callback() {
    @Override
    public void onFailure(Request request, IOException throwable) {
        throwable.printStackTrace();
    }

    @Override
    public void onResponse(Response response) throws IOException {
        if (!response.isSuccessful()) throw new IOException(
            "Unexpected code " + response);
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(context, "Report Received", Toast.LENGTH_SHORT).show();
            }
        });
    }
});

/*Ion.with(getContext(), url)
    .setHeader("X-Client-Type", "Android")
    .setJsonObjectBody(json)
    .asJsonObject()
    .setCallback(new FutureCallback<JsonObject>() {
        @Override
        public void onCompleted(Exception e, JsonObject result) {
            Toast.makeText(context, "Report Received", Toast.LENGTH_SHORT).show();
        }
    });*/

...

private void runOnUiThread(Runnable task) {
    new Handler(Looper.getMainLooper()).post(task);
}

주로 UI 작업을 수행하기 위해 UI 스레드로 돌아 가야하기 때문에 약간 더 많은 작업이 필요하지만 HTTPS의 이점이 있습니다.

JSONObject.toString(); 방법을 사용하십시오 . OkHttp의 튜토리얼을 살펴보십시오.

public static final MediaType JSON
    = MediaType.parse("application/json; charset=utf-8");

OkHttpClient client = new OkHttpClient();

String post(String url, String json) throws IOException {
  RequestBody body = RequestBody.create(JSON, json);
  Request request = new Request.Builder()
      .url(url)
      .post(body)
      .build();
  Response response = client.newCall(request).execute();
  return response.body().string();
}

또 다른 접근 방식은 FormBody.Builder().
다음은 콜백의 예입니다.

Callback loginCallback = new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
        try {
            Log.i(TAG, "login failed: " + call.execute().code());
        } catch (IOException e1) {
            e1.printStackTrace();
        }
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        // String loginResponseString = response.body().string();
        try {
            JSONObject responseObj = new JSONObject(response.body().string());
            Log.i(TAG, "responseObj: " + responseObj);
        } catch (JSONException e) {
            e.printStackTrace();
        }
        // Log.i(TAG, "loginResponseString: " + loginResponseString);
    }
};

Then, we create our own body:

RequestBody formBody = new FormBody.Builder()
        .add("username", userName)
        .add("password", password)
        .add("customCredential", "")
        .add("isPersistent", "true")
        .add("setCookie", "true")
        .build();

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(this)
        .build();
Request request = new Request.Builder()
        .url(loginUrl)
        .post(formBody)
        .build();

Finally, we call the server:

client.newCall(request).enqueue(loginCallback);

You can create your own JSONObject then toString().

Remember run it in the background thread like doInBackground in AsyncTask.

   // create your json here
   JSONObject jsonObject = new JSONObject();
   try {
       jsonObject.put("username", "yourEmail@com");
       jsonObject.put("password", "yourPassword");
       jsonObject.put("anyKey", "anyValue");

   } catch (JSONException e) {
       e.printStackTrace();
   }

  OkHttpClient client = new OkHttpClient();
  MediaType JSON = MediaType.parse("application/json; charset=utf-8");
  // put your json here
  RequestBody body = RequestBody.create(JSON, jsonObject.toString());
  Request request = new Request.Builder()
                    .url("https://yourUrl/")
                    .post(body)
                    .build();

  Response response = null;
  try {
      response = client.newCall(request).execute();
      String resStr = response.body().string();
  } catch (IOException e) {
      e.printStackTrace();
  }
