retrofit2 补丁请求不响应正文答案

【问题标题】：retrofit2 patch request does not response with bodyretrofit2 补丁请求不响应正文
【发布时间】：2019-12-24 12:52:37
【问题描述】：

我正在开发一个带有一些端点的应用程序。总之，当已填充正文时，补丁请求不会回调，并且会出现超时错误。此事件仅适用于补丁请求，其他方法（如 GET、POST、PUT 和 DELETE）工作正常。另一件事是这些端点在 Postman 中都可以正常工作。

我的一项服务

public interface ApiService {

    @Headers({"Accept: application/json;version=0.1.1",
            "Content-Type: application/json; charset=utf-8"})
    @PATCH("api/club/product/{id}/")
    Call<ResponseBody> requestEditProducts(@Header ("Authorization") String token,
                                           @Body RequestBody body,
                                           @Path("id") int id);
}

客户端类

public class RetrofitClient {

    private static Retrofit retrofit = null;

    public static Retrofit getInstance() {
        if (retrofit == null) {

            HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
            logging.setLevel(HttpLoggingInterceptor.Level.BODY);
            OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
            httpClient.addInterceptor(logging);
            httpClient.connectTimeout(120, TimeUnit.SECONDS);
            httpClient.callTimeout(120, TimeUnit.SECONDS);
            httpClient.readTimeout(120, TimeUnit.SECONDS);
            httpClient.writeTimeout(120, TimeUnit.SECONDS);
            httpClient.retryOnConnectionFailure(true);

            retrofit = new Retrofit.Builder()
                    .baseUrl(Consts.BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(httpClient.build())
                    .build();
        }
        return retrofit;
    }
}

一个调用示例

JSONObject object = new JSONObject();
        try {
            object.put("name", "new name");
        } catch (JSONException e) {
            e.printStackTrace();
        }

        RequestBody requestBody = RequestBody.create(okhttp3.MediaType.parse("application/json; charset=utf-8"), object.toString());

        Call<ResponseBody> call = RetrofitClient.getInstance().create(ApiService.class)
                .requestEditProducts(token, requestBody, id);
        call.enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                Log.d("PATCH_REQUEST", "code: " + response.code() +
                        "             body: " + response.body());
            }

            @Override
            public void onFailure(Call<ResponseBody> call, Throwable t) {
                t.printStackTrace();
            }
        });

一次调用结果

D/OkHttp: Content-Type: application/json; charset=utf-8
D/OkHttp: Content-Length: 41

【问题讨论】：

requestEditProducts 和patchMessage 是不同的调用。您能否在示例中发布相同的请求。另外我猜你需要你的 Auth 令牌来进行 patchMessage 请求
我弄错了对不起。帖子已被编辑。不幸的是，后端人员不让我分享令牌和网址@EugeneTroyanskii
这里有 3 个参数 requestEditProducts(@Header ("Authorization") String token, @Body RequestBody body, @Path("id") int id);当你调用这个方法时，你只放了 2 requestEditProducts(requestBody, id);你不能编译这个。
啊，你是对的，我忘了。编辑。非常感谢发现错误@EugeneTroyanskii
邮递员能用吗？

【解决方案1】：

似乎问题在于您重新创建了改造。您必须将此创建包含到您的单例中：

public class RetrofitClient {

    private static ApiService api;

    public static ApiService getInstance() {
        if (api == null) {

            HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
            logging.setLevel(HttpLoggingInterceptor.Level.BODY);
            OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
            httpClient.addInterceptor(logging);
            httpClient.connectTimeout(120, TimeUnit.SECONDS);
            httpClient.callTimeout(120, TimeUnit.SECONDS);
            httpClient.readTimeout(120, TimeUnit.SECONDS);
            httpClient.writeTimeout(120, TimeUnit.SECONDS);
            httpClient.retryOnConnectionFailure(true);

            retrofit = new Retrofit.Builder()
                    .baseUrl(Consts.BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(httpClient.build())
                    .build();
            api = retrofit.create(ApiService.class)
        }
        return api;
    }
}

然后像这样拨打电话：

Call<ResponseBody> call = RetrofitClient.getInstance().create(ApiService.class).requestEditProducts(token, requestBody, id);
call.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            Log.d("PATCH_REQUEST", "code: " + response.code() +
                    "             body: " + response.body());
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            t.printStackTrace();
        }
});

【讨论】：

对不起，由于ISP代理服务器引起的问题。

【解决方案2】：

最后经过大量测试，我们发现错误是由于 ISP 代理问题而发生的。它会导致 PATCH 方法与正文出现问题。

【讨论】：

连接错误不能只影响 PATCH 请求：顺便说一句，你不会忘记添加互联网权限吗？
你在开玩笑吗？ :\ 绝对我添加了互联网许可。但我真的不知道为什么所有请求在 SIM 数据中都能正常工作，而在我的 wifi 模式下，只是 PATCH 请求不起作用。 @EugeneTroyanskii
