void customizeHttpClient(HttpClient httpClient) throws URISyntaxException { URI proxyURI = new URI("http://proxyhost:proxyport"); AuthenticationStore auth = httpClient.getAuthenticationStore(); // Proxy credentials. auth.addAuthentication(new BasicAuthentication( proxyURI, "Websense Content Gateway", // 認證域 "username", // 認證用戶 "passwd")); // 認證密碼 ProxyConfiguration proxyConfig = httpClient.getProxyConfiguration(); HttpProxy proxy = new HttpProxy(proxyURI.getHost(), proxyURI.getPort()); proxyConfig.getProxies().add(proxy); }
其中認證域的值是407 Proxy Authorization Required響應頭中Proxy-Authenticate: Basic realm="Websense Content Gateway"的引號部分。java
如上配置後,就能夠用jetty的HttpClient經過代理髮送http請求了。ui
而在使用jetty-proxy模塊作透明代理時,因爲AbstractProxyServlet在調用createHttpClient()方法的最後,清空了ProtocolHandler(9.2.10.v20150310版本例外),致使若是jetty-proxy向upstream的請求需經過代理的話,那麼以上的配置方式不起做用, jetty-proxy不能自動配置代理認證,提示請求須要代理認證。代理
因此還須要在調用 createHttpClient ()方法後,添加一個ProxyAuthenticationProtocolHandler。code
httpClient.getProtocolHandlers().put(new ProxyAuthenticationProtocolHandler(httpClient));
代碼適用jetty.version=9.4.6.v20170531get
