带有 Raw JSONObject 的 Android API 发布请求返回错误答案

【问题标题】：Android API Post Request with Raw JSONObject returns error带有 Raw JSONObject 的 Android API 发布请求返回错误
【发布时间】：2020-06-23 16:40:33
【问题描述】：

我正在开发一个安卓应用程序。我正在尝试使用 Post 请求将数据发送到服务器。我将 JsonObject 作为原始正文参数发送。这是我的代码。

final NetworkInfo networkInfo = connectivityManager
            .getActiveNetworkInfo();
    final OkHttpClient okHttpClient = new OkHttpClient();
    okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
    okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);
    RestAdapter restAdapter = new RestAdapter.Builder()
            .setEndpoint(Constants.END_POINT)
            .setClient(new OkClient(okHttpClient)).setLogLevel(RestAdapter.LogLevel.FULL).build();

    api = restAdapter.create(API.class);
    if (networkInfo != null && networkInfo.isConnected()) {
        try {
            List<Contacts> sContacts = ContactDatabase
                    .getDatabase(context.getApplicationContext())
                    .contactsDao()
                    .getunlistedContacts("false");

            JSONArray mContactList = new JSONArray();
            for (int i = 0; i < sContacts.size(); i++) {
                try {
                    Contacts obj = sContacts.get(i);
                    Gson gson = new Gson();
                    JSONObject contactJsonObject = new JSONObject(gson.toJson(obj));
                    Log.e("ContactObject++", contactJsonObject.toString());
                    mContactList.put(contactJsonObject);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
            JSONObject mContactsJsonObject = new JSONObject();
            mContactsJsonObject.put("contact_list", mContactList);
            mContactsJsonObject.put(Constants.APIKeys.DEVICE_ID, context.getSharedPreference(Constants.SharedKey.DEVICE_ID));
            mContactsJsonObject.put(Constants.APIKeys.ID, context.getSharedPreference(Constants.SharedKey.USER_ID));
            JSONObject mJsonObject = new JSONObject(api.checkContacts(mContactsJsonObject).toString());
            if (mJsonObject.getBoolean(Constants.APIKeys.STATUS)) {
                JSONArray mUserListJsonArray = mJsonObject.getJSONArray(Constants.APIKeys.USER_LIST);
                for (int i = 0; i < mUserListJsonArray.length(); i++) {
                    JSONObject mUserJsonObject = mUserListJsonArray.getJSONObject(i);
                    String ContactId = mUserJsonObject.getString(Constants.APIKeys.LOCAL_ID);
                    Contacts mContacts = ContactDatabase
                            .getDatabase(context)
                            .contactsDao()
                            .getUserById(ContactId);
                    JSONObject userData = mUserJsonObject.getJSONObject(Constants.APIKeys.USER_DETAILS);
                    mContacts.setUserid(userData.getString(Constants.APIKeys.ID));
                    mContacts.setUserName(userData.getString(Constants.APIKeys.USERNAME));
                    mContacts.setImage(userData.getString(Constants.APIKeys.USER_IMAGE));
                    mContacts.setStatus(userData.getString(Constants.APIKeys.STATUS));
                    if (!mContacts.getPhone().equalsIgnoreCase(context.getSharedPreference(Constants.SharedKey.PHONE))) {
                        ContactDatabase.getDatabase(context.getApplicationContext())
                                .contactsDao()
                                .updateContacts(mContacts);
                    }
                }
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

API接口类是

@POST("/check_Contacts")
JsonObject checkContacts(@Body JSONObject mJsonObject);

而我的 PHP 代码是

public function check_Contacts(){
    $this->load->database();
    $this->load->model('User_Model');
    $this->load->model('Contact_Model');
    $postdata = file_get_contents("php://input");
    $phone='';
    $name='';
    $device_id='';
    $JsonData='';
    $contactArray;
    $JsonData=json_decode($postdata,true);
    $contactArray=$JsonData[contactList];
    $device_id=$JsonData[deviceId];
    $user_id=$JsonData[userid];
    if($this->User_Model->checkDevice($user_id,$device_id))
    {
        $arr = [];
        foreach ($contactArray as $contactObject) {
            $id=$contactObject[userid];
            $name=$contactObject[name];
            $phone=$contactObject[phone];
            if($this->User_Model->phone_exists($phone))
            {
                $user_exist=true;
                $Status=true;
                $StatusCode=Success;
                $userData=$this->User_Model->getUser($phone);
                $user['user_data']=$userData;
                $user['local_id']=$id;
                $user['user_status']=true;
                $arr[]=$user;
                $user_status=1;
                if($this->Contact_Model->checkContact($user_id, $phone)){
                    $user_status=0;
                    $user_exist=true;
                    $message="User exists with the provided no.";
                    $StatusCode=user_exist;
                    $Status=true;

                }else{
                    $this->Contact_Model->addContact($user_id, $phone, $name, $user_status);
                }
            }else
            {
                $user_status=0;
                $this->Contact_Model->addContact($user_id, $phone, $name, $user_status);
                $user_exist=false;
                $message="No User with the provided no.";
                $StatusCode=user_not_exist;
                $Status=true;
            }
        }
        $result[contactList]=$arr;
        $Status=true;
        $StatusCode=Success;
    }else
    {
        $message="Invalid device";
        $StatusCode=invalid_parameter;
        $Status=false;
    }



    $result[message]=$message;
    $result[status]=$Status;
    $result[statusCode]=$StatusCode;

    echo json_encode($result);
}

我在从 Android 调用时收到此错误

但在使用相同数据从 POSTman API 客户端调用该 API 时，它工作得非常好。我在android中缺少什么？请帮助我找到解决方案。

【问题讨论】：

你有一些糟糕的 PHP。 $contactArray=$JsonData[contactList]; 应该是 $contactArray=$JsonData['contactList']; deviceId 和 userId 相同。
它是代码点火器。我已经在常量中声明了这一点。它在 Postman API 客户端中也可以正常工作

            }

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

现在一切正常。
