在使用 Apaches HttpComponent 的 httpclient 时，我一直在尝试从配置的属性中配置代理身份验证的用户和密码，但没有成功。我发现的所有示例都指的是不再可用的方法和类，例如HttpState和setProxyCredentials。

那么，谁能给我一个如何配置代理凭据的示例？

对于任何寻找 4.3 答案的人...它相当新，他们的示例没有使用新的 HttpClientBuilder...所以这就是我在那个版本中实现它的方式：

NTCredentials ntCreds = new NTCredentials(ntUsername, ntPassword,localMachineName, domainName );

CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials( new AuthScope(proxyHost,proxyPort), ntCreds );
HttpClientBuilder clientBuilder = HttpClientBuilder.create();

clientBuilder.useSystemProperties();
clientBuilder.setProxy(new HttpHost(pxInfo.getProxyURL(), pxInfo.getProxyPort()));
clientBuilder.setDefaultCredentialsProvider(credsProvider);
clientBuilder.setProxyAuthenticationStrategy(new ProxyAuthenticationStrategy());

CloseableHttpClient client = clientBuilder.build();

对于 Basic-Auth，它看起来像这样：

DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.getCredentialsProvider().setCredentials(
    new AuthScope("PROXY HOST", 8080),
    new UsernamePasswordCredentials("username", "password"));

HttpHost targetHost = new HttpHost("TARGET HOST", 443, "https");
HttpHost proxy = new HttpHost("PROXY HOST", 8080);

httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);

开箱即用不支持 AFAIK NTLM。但是您可能能够使用NTCredentials并且可能重载来管理它DefaultProxyAuthenticationHandler。

可以在 4.3+ httpClient 上使用普通的旧用户名和密码来代替 NTLM，如下所示：

HttpHost proxy = new HttpHost("x.x.com",8080);
Credentials credentials = new UsernamePasswordCredentials("username","password");
AuthScope authScope = new AuthScope("x.x.com", 8080);
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(authScope, credentials);
HttpClient client = HttpClientBuilder.create().setProxy(proxy).setDefaultCredentialsProvider(credsProvider).build();
HttpResponse response=client.execute(new HttpGet("http://stackoverflow.com/questions/6962047/apache-httpclient-4-1-proxy-authentication"));

如何使用 Apache 的 httpclient 设置代理身份验证

（代理网络上的预授权）

此答案使用 Apache 的 HttpClient v4.1 及更高版本。

接受的答案对我不起作用，但我发现了其他的东西！

下面是一些来自 apache 的经过测试和验证的代码，演示了如何通过代理对 HTTP 请求进行身份验证。

完整的文档位于：https ://hc.apache.org/httpcomponents-client-ga/tutorial/html/authentication.html 。

这里还有一个来自 Apache 的优秀示例：https ://hc.apache.org/httpcomponents-client-ga/httpclient/examples/org/apache/http/examples/client/ClientProxyAuthentication.java

  • 替换my_username为您的代理用户名
  • 替换my_password为您的代理密码
  • 替换proxy.mycompany.com为您的代理主机
  • 替换8080为您的代理端口
  • 替换google.com为您要将 HTTP 请求发送到的站点的主机。
  • 替换/some-path为要将 HTTP 请求发送到的路径。这使用您之前指定的主机站点 (google.com)。

以下示例将验证username:password@proxy.mycompany.com:8080并向其发送GET请求http://www.google.com/some-path并将打印响应 HTTP 代码。

    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(
            new AuthScope("proxy.mycompany", 8080),
            new UsernamePasswordCredentials("my_username", "my_password"));
    CloseableHttpClient httpclient = HttpClients.custom()
            .setDefaultCredentialsProvider(credsProvider).build();
    try {
        //Replace "google.com" with the target host you want to send the request to
        HttpHost target = new HttpHost("google.com", 80, "http");
        HttpHost proxy = new HttpHost("proxy.mycompany", 8080);

        RequestConfig config = RequestConfig.custom()
            .setProxy(proxy)
            .build();
        CloseableHttpResponse response = null;

        //Replace "/some-path" with the path you want to send a get request to.
        HttpPost httppost = new HttpPost("/some-path");
        httppost.setConfig(config);
        response = httpclient.execute(target, httppost);

        try {
            System.out.println("Return status code is "+response.getStatusLine().getStatusCode());          
        } finally {
            response.close();
        }
    } finally {
        httpclient.close();
    }

对 NTLM 来说，一个更简单的事情对我有用：

httpclient.getCredentialsProvider().setCredentials(
                    new AuthScope(proxy_host, proxy_port), 
                    new NTCredentials(this.proxy_user, this.proxy_pass, this.proxy_host, this.proxy_domain));
HttpHost proxy = new HttpHost(this.proxy_host, this.proxy_port, "http");
httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);

对于 HttpClient 4.5 和每个请求身份验证：

HttpContext httpContext = new BasicHttpContext();
AuthState authState = new AuthState();

authState.update(new BasicScheme(), new UsernamePasswordCredentials("userName", "password"));
httpContext.setAttribute(HttpClientContext.PROXY_AUTH_STATE, authState);
CloseableHttpResponse httpResponse = httpClient.execute(httpRequest, httpContext);

如果你必须让你的代码使用 4.1 或者想要使用下面的代码片段，重要的是要知道 httpclient 4.1 不会将身份验证发送到代理。您可能会收到 407“需要代理身份验证”状态代码。我升级到 4.3.3并且一切正常，尽管 DefaultHttpClient 和 ConnRoutePNames 在此版本中已被弃用。希望这可以帮助！

DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.getCredentialsProvider().setCredentials(
    new AuthScope("PROXY HOST", 8080),
    new UsernamePasswordCredentials("username", "password"));

HttpHost proxy = new HttpHost("PROXY HOST", 8080);

httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
