改型2-空响应主体

Question

{
    "errorNumber":4,
    "status":0,
    "message":"G\u00f6nderilen de\u011ferler kontrol edilmeli",
    "validate":[
        "Daha \u00f6nceden bu email ile kay\u0131t olunmu\u015f. L\u00fctfen giri\u015f yapmay\u0131 deneyiniz."
    ]
}

但是我总是在onresponse方法中获得null响应。因此，我尝试使用response.errorbody.string()查看响应的错误主体。错误正文包含与原始响应完全相同的内容。

@FormUrlEncoded
@POST("/Register")
@Headers("Content-Type: application/x-www-form-urlencoded")
Call<RegisterResponse> register(
        @Field("fullName")  String fullName,
        @Field("email")     String email,
        @Field("password")  String password);

public class RegisterResponse {
    public int status;
    public String message;
    public int errorNumber;
    public List<String> validate;
}

OkHttpClient client = new OkHttpClient();
client.interceptors().add(new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Response response = chain.proceed(chain.request());
        final String content = UtilityMethods.convertResponseToString(response);
        Log.d(TAG, lastCalledMethodName + " - " + content);
        return response.newBuilder().body(ResponseBody.create(response.body().contentType(), content)).build();
    }
});
Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .addConverterFactory(GsonConverterFactory.create())
        .client(client)
        .build();
domainSearchWebServices = retrofit.create(DomainSearchWebServices.class);

我用JSONSchema2POJO控制了responseJSON，看看我是否修改了我的响应类wright，它似乎可以。

为什么改型无法转换我的响应？

if (response.code() == 400 ) {
    Log.d(TAG, "onResponse - Status : " + response.code());
    Gson gson = new Gson();
    TypeAdapter<RegisterResponse> adapter = gson.getAdapter(RegisterResponse.class);
    try {
        if (response.errorBody() != null)
            registerResponse = 
                adapter.fromJson(
                    response.errorBody().string());
    } catch (IOException e) {
        e.printStackTrace();
    }
}
