Java Apache HTTP 401 响应返回正确的凭据

Question

我正在尝试使用 Apache HttpClient 访问 REST API link，但我一直收到返回的 401 错误。在提示输入密码后，我可以在浏览器中转到 URL 时登录。我使用的代码如下：

        CredentialsProvider provider = new BasicCredentialsProvider();
        UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(creds.get(0), creds.get(1));
        provider.setCredentials(AuthScope.ANY, credentials);

        AuthCache authCache = new BasicAuthCache();
        authCache.put(new HttpHost(uri.getHost(), uri.getPort(), "https"), new BasicScheme());

        BasicHttpContext context = new BasicHttpContext();
        context.setAttribute(ClientContext.CREDS_PROVIDER, provider);
        context.setAttribute(ClientContext.AUTH_CACHE, authCache);

        DefaultHttpClient client = new DefaultHttpClient();
        client.setHttpRequestRetryHandler(new DefaultHttpRequestRetryHandler());
        client.setCredentialsProvider(provider);
        HttpResponse response = null;
        try
        {
            // response = client.execute(new HttpGet(uri));
            response = client.execute(new HttpGet(uri), context);
        }
        catch(IOException e)
        {
            logger.error("Error running authenticated get request: " + e);
        }

我正在使用 HttpClient 4.2.3，不幸的是我无法升级它。

如有任何帮助，我们将不胜感激！谢谢！

编辑： 原来我需要提供证书，比如在 curl 中使用 -cacert，但是我找不到这样的例子！

由于您需要提供证书，也许这可以帮助您：

我认为该示例符合 4.2.3。
