java - 如何在 Jersey 和 Apache Http 客户端中使用代理身份验证？

Question

我正在使用带有 ApacheConnection Provider 的 Jersey 客户端。

    Builder builder = RequestConfig.custom().setConnectTimeout(timeout);
    List<Proxy> proxies = ProxyManager.getInstance().select(baseUrl.toURI());
    if (useProxy) {
        ...
        builder.setProxy(new HttpHost(proxyUri.getHost(), proxyUri.getPort()));
    }
    RequestConfig requestConfig = builder.build();

    final ClientConfig clientConfig = new ClientConfig();
    clientConfig.property(ApacheClientProperties.REQUEST_CONFIG, requestConfig);
    clientConfig.connectorProvider(new ApacheConnectorProvider());

    client = ClientBuilder.newBuilder().withConfig(clientConfig).sslContext(getSSLContext()).build();
    client.property(ClientProperties.CONNECT_TIMEOUT, 5000);

但是如何添加代理身份验证的用户名和密码？

似乎 apache 连接提供程序不使用标准的 java 代理选择器机制。

我终于自己找到了解决方案。不幸的是，这没有记录在任何地方:

HttpHost proxyhost = new HttpHost(host,pw);

CredentialsProvider credsProvider = new BasicCredentialsProvider();

credsProvider.setCredentials(new AuthScope(proxyhost), new UsernamePasswordCredentials(user, pw));
clientConfig.property(ApacheClientProperties.CREDENTIALS_PROVIDER, credsProvider);

builder.setProxy(proxyhost);
