Question

我目前正在使用带代理信息的获取请求：

String result1 = Request.Get("_http://somehost/")
        .version(HttpVersion.HTTP_1_1)
        .connectTimeout(1000)
        .socketTimeout(1000)
        .viaProxy(new HttpHost("myproxy", 8080))
        .execute().returnContent().asString();

结果是＆＃34;需要代理身份验证＆＃34;错误。我相信发出请求的服务器需要用户名和密码吗？如果是这样，我该如何添加该细节？我之前从未使用过Fluent API。

Answer 1

您需要CredentialsProvider。

final CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(new AuthScope(proxy), new UsernamePasswordCredentials(username, password));

final HttpPost httppost = new HttpPost(uri);
httppost.setConfig(RequestConfig.custom().setProxy(proxy).build());

String line = HttpClientBuilder.create().setDefaultCredentialsProvider(credsProvider).build() .execute(httppost).getStatusLine());

此外，4.3.1中存在影响身份验证的错误。它在4.3.2中修复。 https://issues.apache.org/jira/browse/HTTPCLIENT-1435

Answer 2

以下是使用Fluent API的示例。执行程序可用于指定代理的凭据。

    HttpHost proxyHost = new HttpHost("myproxy", 8080);

    Executor executor = Executor.newInstance()
        .auth(proxyHost, "username", "password");

    String result1 = executor.execute(Request.Get("_http://somehost/")
        .viaProxy(proxyHost))
        .returnContent()
        .asString();

Answer 3

Executor executor = Executor.newInstance()
        .auth(new HttpHost("myproxy", 8080), "username", "password")
        .authPreemptive(new HttpHost("myproxy", 8080));
Response response = executor.execute(<your reques>);

使用Fluent API请求进行代理验证？
