apache httpclient 4.3 没有超时 [英] apache httpclient 4.3 not timing out

问题描述

我无法使用以下代码使 Apache HttpClient (4.3) 发布请求超时:

I am having trouble getting the Apache HttpClient (4.3) post request to timeout using the following code:

RequestConfig requestConfig = RequestConfig.custom().setConnectionRequestTimeout(4000).setConnectTimeout(4000)
        .setSocketTimeout(4000).build();

CloseableHttpClient client = HttpClients.custom().setSslcontext(sslContext)
        .setHostnameVerifier(SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER)
        .setDefaultRequestConfig(requestConfig).build();

HttpPost post = new HttpPost("https://localhost:" + connection.getLocalPort() + "/API/webservice.asmx");

StringEntity stringE = new StringEntity(REQUEST);
    post.setEntity(stringE);

CloseableHttpResponse response = client.execute(post);

我通过专有 API 获取连接和端口.当一切顺利时，这会起作用，但是有时(由于我认为连接不好)，代码会永远挂在 client.execute(post) 上.我在实现超时或其他一些使该调用超时的方法时做错了什么，所以我不会无限期地卡住.

I am getting the connection and port via a proprietary API. When everything goes well this works however sometimes (due to a bad connection I believe) the code hangs forever at client.execute(post). Is there something I am doing wrong here in implementing the timeout or some other method to make that call have a timeout so I'm not stuck indefinitely.

推荐答案

这是 HttpClient 4.3 中 https 连接的错误.在尝试 SSL 握手之前，套接字上未设置套接字超时.线程可能会在握手期间挂起等待套接字读取.HttpClient 4.2 没有这个错误.

This is a bug with https connections in HttpClient 4.3. The socket timeout is not set on the socket before the SSL handshake is attempted. The thread may hang waiting on socket read during the handshake. HttpClient 4.2 does not have this bug.
