Android 为什么我的进程侦听器更新回调没有在OKHttp拦截器中被调用？

我已经构建了一个精简的Android应用程序，可以使用签名URL将文件上传到AmazonS3。这些URL需要PUT调用，这与大多数通过POST进行的文件上传略有不同

我只是将S3URL粘贴到textview中。我已经验证了s3url可以使用这个cURL命令，所以一切都很好

curl-X PUT'https://mybucket.s3.us-west-2.amazonaws.com/uploads/android/somevideo.mp4?X-Amz算法=AWS4-HMAC-SHA256&X-Amz-Credentia…0&X-Amz-Signature=21312123&X-Amz-SignedHeaders=host'--上传文件~/Downloads/video.mp4

文件上传在Android应用程序内正确完成，但我从未进入我的

update

回调，因此我无法更新对话框中的进度条

因为我正在执行一个PUT请求，而这不是一个多部分表单上传（我只是以八位字节流的形式发送文件体），所以会发生一些不同的情况吗

我的活动代码和内部进度类都在下面的一个文件中。当我在第126行设置断点（更新函数）时，我从不输入断点。我使用了，但由于某种原因，我的代码从未被调用

Android清单具有正确的internet权限，我已在应用程序权限中启用了读取权限

<?xml version="1.0" encoding="utf-8"?>

    package="com.example.putuploadwithprogress">

        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

如前所述，问题在于，这是在拦截响应，而不是请求

拦截器需要进行如下更改：

.addNetworkInterceptor(new Interceptor() {
          @Override
          public Response intercept(Chain chain) throws IOException {
            Request originalRequest = chain.request();

            if (originalRequest.body() == null) {
              return chain.proceed(originalRequest);
            }
            Request progressRequest = originalRequest.newBuilder()
                .method(originalRequest.method(),
                    new CountingRequestBody(originalRequest.body(), progressListener))
                .build();

            return chain.proceed(progressRequest);

          }

      super(delegate);
    }

    @Override public void write(Buffer source, long byteCount) throws IOException {
      super.write(source, byteCount);

      bytesWritten += byteCount;
      listener.onRequestProgress(bytesWritten, contentLength());
    }
  }

  public static interface Listener {

    public void onRequestProgress(long bytesWritten, long contentLength);
  }
}

如前所述，问题是，这是拦截响应，而不是请求

拦截器需要进行如下更改：

.addNetworkInterceptor(new Interceptor() {
          @Override
          public Response intercept(Chain chain) throws IOException {
            Request originalRequest = chain.request();

            if (originalRequest.body() == null) {
              return chain.proceed(originalRequest);
            }
            Request progressRequest = originalRequest.newBuilder()
                .method(originalRequest.method(),
                    new CountingRequestBody(originalRequest.body(), progressListener))
                .build();

            return chain.proceed(progressRequest);

          }

是否为每个字节读取调用函数读取（缓冲区接收器，长字节计数）？@NIKHILMAURYA不，我没有看到命中率。我认为您正在跟踪响应体的进度，而不是请求体。尝试使用BufferedSink方法尝试这是为每个字节读取调用的函数读取（Buffer sink，long byteCount）？@NIKHILMAURYA不，我没有看到命中率。我认为您正在跟踪响应体而不是请求体的进度。尝试使用BufferedSink方法尝试以下操作
