java - Retrofit 2 RequestBody writeTo() 方法调用了两次

Question

Retrofit 2 RequestBody writeTo()方法调用了两次，我使用的代码如下:

ProgressRequestBody requestVideoFile = new ProgressRequestBody(videoFile, new ProgressRequestBody.UploadCallbacks() {

    VideoUploadStore store = new VideoUploadStore();

    @Override
    public void onProgressUpdate(int percentage) {
        if (!mIsCancelled) {
            Log.i("UploadServiceManager", "Read Percentage : " + percentage);
            data.setUploadPercentage(percentage);
            store.updateUploadData(data);
        }
    }

    @Override
    public void onError() {
        if(!mIsCancelled) {
            data.setUploadPercentage(0);
            store.updateUploadData(data);
        }
    }

    @Override
    public void onFinish() {

    }
});
MultipartBody.Part multipartVideo = MultipartBody.Part.createFormData("File", videoFile.getName(), requestVideoFile);

下面的解决方案可能会帮助您解决问题，尽管可能为时已晚。 :p

删除 Api 客户端中的 HttpLoggingInterceptor 对象，它不会执行 writeTo() 函数两次。基本上，HttpLoggingInterceptor 通过调用首先加载数据缓冲区(用于内部日志记录目的) writeTo() 然后再次调用 writeTo() 将数据上传到服务器。

  HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
  logging.setLevel(HttpLoggingInterceptor.Level.BODY);
  httpClient.addInterceptor(logging);
