我有一种方法可以连接将发布数据发送到 Web 服务并返回如下响应：

public HttpResponse sendXMLToURL(String url, String xml, String httpClientInstanceName) throws IOException {
    HttpResponse response = null;

    AndroidHttpClient httpClient = AndroidHttpClient.newInstance(httpClientInstanceName);
    HttpPost post = new HttpPost(url);

    StringEntity str = new StringEntity(xml);
    str.setContentType("text/xml");
    post.setEntity(str);

    response = httpClient.execute(post);

    if (post != null){
        post.abort();
    }
    if (httpClient !=null){
        httpClient.close();
    }

    return response;
}

然后，在我的片段的 AsyncTask 中，我尝试使用 getEntity() 读取响应：

HttpResponse response = xmlUtil.sendXMLToURL("url", dataXML, "getList");

            //Check if the request was sent successfully
            if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                // Parse result to check success
                responseText = EntityUtils.toString(response.getEntity());

                if (!xmlParser.checkForSuccess(responseText, getActivity())){
                    //If webservice response is error
                    ///TODO: Error management
                    return false;
                }
            }

当我到达那条线时：

responseText = EntityUtils.toString(response.getEntity());

我得到一个例外：java.net.SocketException: Socket closed.

这种行为不会一直发生，也许每隔一段时间就会发生一次。

写吧

HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(your url);
HttpResponse response = client.execute(post);

它应该可以工作。无需编写会造成混乱的代码。

在使用使用 HttpClientBuilder 构建的客户端实例时，我也遇到了“套接字关闭”异常。就我而言，在处理响应对象（在父方法中）之前，我在 finally 块中对我的请求对象调用 HttpRequestBase.releaseConnection() 。翻转事情解决了这个问题......（下面的工作代码）

    try {
        HttpResponse response = httpClient.execute(request);
        String responseBody = EntityUtils.toString(response.getEntity());
        // Do something interesting with responseBody       
    } catch (IOException e) {
        // Ah nuts...
    } finally {
        // release any connection resources used by the method
        request.releaseConnection();
    }
