okhttp，Connection

Question

我目前正在学习android，而okhttp3遇到了一些问题。 这是堆栈跟踪。

我的工作环境是Apache 2.4.34，Windows 10，Android Studio 3.1.3和minSdkVersion22。OKHTTP版本是3.11.0

我的示例代码是：

private void sendRequestWithOKHttp() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    OkHttpClient client = new OkHttpClient.Builder()
                            .retryOnConnectionFailure(true)
                            .build();
                    Request request = new Request.Builder()
                            .url("http://10.0.2.2:8099/get_data.xml")
                            .addHeader("Connection", "close")
                            .get()
                            .build();
                    Response response = client.newCall(request).execute();
                    String responseData = response.body().string();
                    parseXMLWithPull(responseData);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }

我首先不小心解决了Apache httpd.conf文件的问题：

# Various default settings
Include conf/extra/httpd-default.conf

# Configure mod_proxy_html to understand HTML4/XHTML1
<IfModule proxy_html_module>
#Include conf/extra/httpd-proxy-html.conf
</IfModule>

但是后来这个问题每次都会发生，我不知道发生了什么。 有什么解决办法吗？
