Question

我使用关注代码，但始终有错误：

    public static void connect(CloudCredentials credentials, final CloudProxy proxy) throws Exception {
    ApplicationTokenCredentials azCredential = new ApplicationTokenCredentials(credentials.getClientID(), 
            credentials.getTenantID(), credentials.getClientKey(), AzureEnvironment.AZURE);
    try {
        Configurable config = Azure.configure()
                .withConnectionTimeout(30, TimeUnit.SECONDS)
                .withReadTimeout(60, TimeUnit.SECONDS);
        if (proxy != null) {
            config.withProxy(new Proxy(Type.HTTP, new InetSocketAddress(proxy.getProxyHost(), proxy
                    .getProxyPort())));
            if (proxy.getProxyUsername() != null && proxy.getProxyUsername().trim().length() > 0) {
                Authenticator.setDefault(new Authenticator() {
                    @Override
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(proxy.getProxyUsername(), proxy.getProxyPassword()
                                .toCharArray());
                    }
                });
                config.withProxyAuthenticator(new JavaNetAuthenticator());
            }
        }
        Authenticated authenticate = config.authenticate(azCredential);
        authenticate.withSubscription(credentials.getSubscription()).getCurrentSubscription().displayName();
        System.out.println(authenticate);
    } catch (Exception e) {
        System.out.println(e);
    }
}

但代理我相信没关系。我有另一个测试代码。它运作良好：

    String a = "111";
    System.out.print(a.toCharArray());

    Authenticator.setDefault(new Authenticator() {
        public PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("test", "111".toCharArray());
        }
    });
    URLConnection connection;
    try {
        connection = new URL(
                "http://devio.us/~ricky/stackoverflow-protected/nothingtosee.html")
                .openConnection(new Proxy(Type.HTTP, new InetSocketAddress("192.168.1.59", 808)));

        System.out.println(new BufferedReader(new InputStreamReader(
                connection.getInputStream(), "UTF-8")).readLine());

    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

我不想使用System.setProperty设置代理，因为所有java连接都将通过代理。在Azure文档中，我找不到任何代理信息。谁能帮我？非常感谢你。

现在，代理在设置隧道时需要基本身份验证对于HTTPS，默认情况下将不再成功。如果需要，这个可以通过从中删除Basic来重新激活身份验证方案 jdk.http.auth.tunneling.disabledSchemes网络属性，或者将同名的系统属性设置为＆＃34;＆＃34; （空）上命令行。

您可以从Disable Basic authentication for HTTPS tunneling找到它。

因此，您可以在net.properties中找到jdk/jre/lib directory个文件。（对我来说，它是C:\Program Files\Java\jdk1.8.0_144\jre\lib）。

然后更改变量

jdk.http.auth.tunneling.disabledSchemes 
jdk.http.auth.proxying.disabledSchemes

清空如：

jdk.http.auth.tunneling.disabledSchemes=
jdk.http.auth.proxying.disabledSchemes=

请重试您的代码。如有任何疑虑，请随时让我知道。

如何在java开发中在Azure（版本1.1.2）上设置代理？
