使用Jetty Http Client 接收较大数据时发生异常

Request request = client.POST(api_url)
   .timeout(TIMEOUT, TimeUnit.SECONDS)
   .content(new BytesContentProvider(imageData), "image/*");

ContentResponse resp = request.send();

if(resp.getStatus()==200){

    request.getContent();

}

 send 函数抛出如下异常：

 java.lang.IllegalArgumentException: Buffering capacity 2097152 exceeded

 后分析发现，再接收较大数据时，超出内部buffer，进而产生异常，解决方法，使用InputStreamResponseListener 来读取数据。

Request request = client.POST(api_url)
   .timeout(TIMEOUT, TimeUnit.SECONDS)
   .content(new BytesContentProvider(imageData), "image/*");

InputStreamResponseListener listener = new InputStreamResponseListener();
request.send(listener);
HttpResponse resp = (HttpResponse) listener.get(12,TimeUnit.SECONDS);

if(resp.getStatus()==200){

   InputStream input = listener.getInputStream()

  // read data from input.

}
