我试图点击 google api 的 https url。使用下面的代码，但它给出了一些错误。但我可以点击一个 google api http url 并且它运行良好，没有任何错误
DataInputStream di = null;
FileOutputStream fo = null;
byte[] b = new byte[1];
// PROXY
System.setProperty("https.proxyHost", "my proxy");
System.setProperty("https.proxyPort", "8080");
Authenticator.setDefault(new PasswordAuthenticator());
URL u = new URL("https://maps.googleapis.com/maps/api/place/autocomplete/json?input=Vict&types=geocode&language=fr&sensor=true&key=keyforuse");
HttpURLConnection con = (HttpURLConnection) u.openConnection();
sun.misc.BASE64Encoder encoder = new sun.misc.BASE64Encoder();
String encodedUserPwd = encoder.encode("domain\user:password"
.getBytes());
con.setRequestProperty("Proxy-Authorization", "Basic "
+ encodedUserPwd);
di = new DataInputStream(con.getInputStream());
// result = parseJSON(di);
while (-1 != di.read(b, 0, 1)) {
System.out.print(new String(b));
}
but getting error below
但在下面出现错误

You may not need the domain in front of the username. I had a very similar issue, and I fixed it when I removed the domain in front of the username. Since the proxy server is on a domain, I think it implies that your under the same domain.
您可能不需要用户名前面的域。我有一个非常相似的问题，当我删除用户名前面的域时，我修复了它。由于代理服务器在一个域上，我认为这意味着您在同一个域下。

I fixed it by authenticating to the proxy server with my user name and password. If you are on your company's network , it can be your sso cred too. The equivalent of this will be like this :
我通过使用我的用户名和密码对代理服务器进行身份验证来修复它。如果您在公司的网络上，它也可以成为您的 sso 信誉。等价的将是这样的：
-Dhttp.proxyUser=myusername
-Dhttp.proxyPassword=mypassword
-Dhttp.proxyHost=myproxyserver.com
-Dhttp.proxyPort=9000
