使用 HttpProxy 通过抢占式身份验证连接到主机

发布于 2024-11-01 09:20:10 字数 1092 浏览 4 评论 0原文

我正在使用 HttpClient 连接到需要 BasicAUTH 的主机。但代理不需要任何身份验证。我已将其设置如下：

private final HttpClient httpClient; // Spring injected

设置基本身份验证：

private void setBasicAuth(final String username, final String password) {
    httpClient.getState().setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM), new UsernamePasswordCredentials(username, password));
    httpClient.getParams().setAuthenticationPreemptive(true);
}

设置代理：

private void setProxy(final String proxyHost, final int proxyPort) {
    hostConfiguration hostConfiguration = httpClient.getHostConfiguration();
    hostConfiguration.setProxy(proxyHost, proxyPort);
}

但在运行代码时收到以下警告。一切正常，但我也想摆脱警告（或至少了解它们出现的原因）

WARN  o.a.c.httpclient.HttpMethodDirector - Required proxy credentials not available for BASIC <any realm>@proxy.XXXXXX.no:3128
WARN  o.a.c.httpclient.HttpMethodDirector - Preemptive authentication requested but no default proxy credentials available

有什么想法吗？

原文

I am using HttpClient to connect to a host which requires BasicAUTH. But the proxy doesn't require any authentication. I have set it up as follows:

private final HttpClient httpClient; // Spring injected

Setting Basic auth:

private void setBasicAuth(final String username, final String password) {
    httpClient.getState().setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM), new UsernamePasswordCredentials(username, password));
    httpClient.getParams().setAuthenticationPreemptive(true);
}

Setting proxy:

private void setProxy(final String proxyHost, final int proxyPort) {
    hostConfiguration hostConfiguration = httpClient.getHostConfiguration();
    hostConfiguration.setProxy(proxyHost, proxyPort);
}

But I get the following warnings when running the code. Everything works, but I want to get rid of the warnings as well (or at least understand why they appears)

WARN  o.a.c.httpclient.HttpMethodDirector - Required proxy credentials not available for BASIC <any realm>@proxy.XXXXXX.no:3128
WARN  o.a.c.httpclient.HttpMethodDirector - Preemptive authentication requested but no default proxy credentials available

Any ideas?

以下是 Apache 站点上没有凭据的代理示例：

（来自<一个href="http://hc.apache.org/httpcomponents-client-ga/examples.html" rel="nofollow">http://hc.apache.org/httpcomponents-client-ga/examples.html)

您收到错误是因为您传递了用户名/密码，但不需要这样做。

警告消息来自记录器 (http://hc.apache.org/httpcomponents-client-ga/logging.html) - 取决于您如何设置记录器，您可以忽略那。

在花费了太多时间尝试让 Java 应用程序处理代理服务器之后，我可以告诉您，使用 Proxifier 等工具（ http://www.proxifier.com/ 适用于 Mac OS X 和 Windows) 或 CNTLM ( http://cntlm.sourceforge.net/) 更容易、更灵活、更容易调试，并且保持代码干净。
