无法使用不可重复的请求实体重试请求 [英] Cannot retry request with a non-repeatable request entity

问题描述

我在客户端使用java-http-client库和Apache Transport，在服务器端使用Rails。有时会出现这样的错误：

I'm using java-http-client library and Apache Transport with it on client side and Rails on server side. From time to time a get error like this:

11-24 17:37:02.469: WARN/BaseActivity(5925): org.apache.http.client.ClientProtocolException

我该怎么做才能避免这种情况？

What should I do to avoid this?

推荐答案

我有一个类似的错误，因为我使用CountingInputStreamEntity是一个不可重复的http客户端。解决方案是使用BufferedHttpEntity将不可重复的转换为可重复的httpclient。

I have an similar error because I used CountingInputStreamEntity that is a non-repeteable http client. The solution was to use BufferedHttpEntity which converted the non-repeteable to repeteable httpclient.

ParcelFileDescriptor fileDescriptor = this.getContentResolver().openFileDescriptor(uri, "r");
            InputStream in = this.getContentResolver().openInputStream(uri);

            CountingInputStreamEntity entity = new CountingInputStreamEntity(in, fileDescriptor.getStatSize());
            entity.setUploadListener(this);
            entity.setContentType("binary/octet-stream");
            entity.setChunked(true); 

            BufferedHttpEntity myEntity = null;
            try {
                myEntity = new BufferedHttpEntity(entity);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            put.setEntity(myEntity);
