Question

我正在开发具有某些端点的应用程序。总而言之，补丁请求在填充主体时不会回调，并且会发生超时错误。此事件仅发生在补丁程序请求中，其他方法（例如GET，POST，PUT和DELETE）可以正常工作。另一件事是这些端点在Postman中都能正常工作。

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;
    }
}

一个通话示例

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();
            }
        });

问题似乎在于您重新创建了Retrofit。您必须将此创建内容添加到您的单例中：

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();
        }
});

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。会导致身体的PATCH方法出现问题。
