异常:java.net.SocketException:来自服务器的文件的意外结束

Question

我有以下代码，我一直得到一个错误

public static HttpsURLConnection getRestConnectionWithProxy(String urlString) throws MalformedURLException,
                   IOException {

URL url = new URL(null, urlString, new sun.net.www.protocol.https.Handler());
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(getProxy());

return conn;
}
private static Proxy getProxy() {
if (proxy == null) {
Map<String, String> connectionParams = null;

String proxyIP = "proxyIP";
int proxyPort = 80;
proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyIP, proxyPort));

}
return proxy;
}

我得到的错误如下

Exception: java.net.SocketException: Unexpected end of file from server

你知道可能是什么原因导致这个错误吗?

Answer 1

正如您在堆栈跟踪中看到的那样，有可能与您通信的服务器在建立连接后突然关闭连接。可能是服务器暂时无法处理您的请求，或者是防火墙/路由器出现问题，导致网络数据包丢失。

可能存在诸如身份验证头丢失等问题，但无法确认共享信息有限。

你可能需要开始看

检查路由器日志是否有;查看路由器是否有问题。

试着看看你的编码(例如UTF-8)是正确的内容类型。
