Question

我在使用改造2进行POST请求时遇到了麻烦。我正在尝试使用Retrofit的GsonConverterFactory将POJO对象转换为JSON。

我有GET请求使用GsonConverterFactory将主体转换为POJO类，但在POST上它似乎不起作用（POJO到JSON）。我在Android Studio中使用它并使用Gradle来构建我的项目。这些是我的Gradle依赖项：

compile 'com.squareup.retrofit2:retrofit:2.0.1'
compile 'com.squareup.okhttp:okhttp:2.7.5'
compile 'com.google.code.gson:gson:2.6.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.1'

这是我的Api界面代码：

public interface EhabrApi {
    @POST("/create-account")
    Call<ResponseBody> createUser(@Body User user);
}

这是发出请求的代码：

    User newUser = new User("Bob", "Smith", "bob@gmail.com", "password", "Seattle", "1990-01-01");

    System.out.println("User is " + new Gson().toJson(newUser));

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(API_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    EhabrApi ehabrApi = retrofit.create(EhabrApi.class);
    Call<ResponseBody> call = ehabrApi.createUser(newUser);
    System.out.println("Request is " + new Gson().toJson(call.request()));

    call.enqueue(new Callback<ResponseBody>() {
           @Override
           public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
               int statusCode = response.code();
               System.out.println("Recieved " + statusCode);
           }

           @Override
           public void onFailure(Call<ResponseBody> call, Throwable t) {
               System.out.println("Failed call " + t);
               System.out.println("stack trace: ");
               t.printStackTrace();
           }
        }
    );

这是我的输出和堆栈跟踪：

Creating new account

修改现在我按照建议放入拦截器。 POST请求看起来对我来说......这是：

--> POST http://[mywebpageurl.com]/create-account http/1.1
Content-Type: application/json; charset=UTF-8
Content-Length: 125
{"Birthday":"1990-01-01","City":"Seattle","Email":"bob@gmail.com","FirstName":"Bob","LastName":"Smith","Password":"password"}
--> END POST (125-byte body)
<-- 200 OK http://[mywebpageurl.com]/create-account (100ms)

Answer 1

你的logcat消息中很清楚

Failed call com.google.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $

因此，这意味着您等待JSONObject但是由于您的请求，您将获得格式错误的JSONObject。要解决问题，请检查您的JSON响应。

Retrofit 2.0.1发布JSON - MalformedJsonException
