java - eclipse 使用 https 时出现代理问题

Question

我在从 eclipse 发送 https 请求时遇到问题。当我运行此代码时，它工作正常。

public class HttpConnectionTest extends TestCase{

    @Test
    public void testConnection() throws HttpException, IOException {
        int statusCode = new HttpClient().executeMethod(new GetMethod("http://www.google.com"));
        assertTrue(statusCode == HttpStatus.SC_OK);
    }
}

但是当我为“https://www.google.com”运行相同的代码时，我得到以下异常；

java.net.ConnectException: Connection timed out: connect

   at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:79)

我正在通过代理连接到互联网。我的网络设置是like this ;我看到有些人说禁用 socks ，但 eclipse 不允许我取消选中 socks 选项(我正在使用 eclipse luna)

我相信您在 eclipse 设置中配置的代理是用于插件和 IDE 相关的东西..

您必须在运行时在代码中设置代理，如下所示:
