java.net.SocketException异常：连接复位，使用HttpURLConnection的上页GET

Question

编程变得页面与Java（HttpURLConnection类）给我的错误java.net.SocketException异常：连接复位。对Python和与邮差。

试图与其他网页，如Gmail登录页面，电子银行登录页面等，和它的作品，但只有一个网站（一个我需要它的工作）没有。与Python脚本Succeded，邮差也可以，但是Java的不

String url="https://********************/Login";
URL obj = new URL(url);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        con.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");
        con.setRequestProperty("Cache-Control", "no-cache");
        con.setRequestMethod("GET");

        int responseCode = con.getResponseCode();

预计不会抛出异常。实际的结果是：

java.net.SocketException: Connection reset

    at java.net.SocketInputStream.read(SocketInputStream.java:141)

...

Python脚本其中工程：

import urllib.request  as urllib2 
content = urllib2.urlopen('https://******************/Login').read()
print(content)

Answer 1

尝试HttpsURLConnection的：

String url = "https://********************/Login";
URL obj = new URL(url);
HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();

代码sun.net.www.http.HttpClient.parseHTTPHeader（HttpClient.java:735）

也许一个代理是问题的原因。
