我用谷歌搜索了三个小时，没有发现任何帮助。我有 WebClient ，它通过 socks 5 连接到一些站点，这些站点不需要使用登录名和密码来工作：

WebClient wc = new WebClient(BrowserVersion.FIREFOX_3_6);
        wc.setProxyConfig(new ProxyConfig(socks.split(":")[0], Integer.parseInt(socks.split(":")[1]), true));
        wc.setTimeout(30000);
        wc.setCssEnabled(false);
        wc.setJavaScriptEnabled(false);

等等。我收到了不需要登录名或密码的每个活动主机的下一个例外：

和

Dec 12, 2011 4:14:02 AM org.apache.http.impl.client.DefaultRequestDirector tryConnect
INFO: I/O exception (java.net.SocketException) caught when connecting to the target host: SOCKS : authentication failed

HTML 单元 2.9。我尝试使用凭据：

WebClient wc = new WebClient(BrowserVersion.FIREFOX_3_6);
        wc.setProxyConfig(new ProxyConfig(socks.split(":")[0], Integer.parseInt(socks.split(":")[1]), true));
        wc.setTimeout(30000);
        wc.setCssEnabled(false);
        wc.setJavaScriptEnabled(false);

        final DefaultCredentialsProvider credentialsProvider = (DefaultCredentialsProvider) wc.getCredentialsProvider();
        credentialsProvider.addCredentials("", "", socks.split(":")[0], Integer.parseInt(socks.split(":")[1]), null);
        credentialsProvider.addProxyCredentials("", "");

        wc.setCredentialsProvider(credentialsProvider);

但这没有任何意义。而且我认为这个问题不在 HtmlUnit 中，而是在 Java 中，因为我尝试通过 HtmlUrlConnection 使用袜子，并且发生了同样的错误，这让我哭了。大佬们，怎么实现呢？我花了大约六个小时来解决这个问题，但我无法使用 System.setProperty，因为我需要为每个 WebClient“窗口”设置不同的袜子。

您是否尝试过使用空值而不是空字符串？

顺便说一句，不推荐使用 addProxyCredentials()
