Apache HttpComponents中的第一个请求中不发送代理授权标头

我正在使用Apache HttpComponents (4.5.2),我正在尝试通过代理服务器(SSH隧道)请求HTTPS页面。

问题是根据日志客户端发送没有Proxy-Authorization标头的第一个请求,但在代理响应407错误(需要代理身份验证)后,它会通过发送Proxy-Authorization标头退出身份验证。

我认为我的代码存在问题,我需要启用原始身份验证,但我找不到任何有关如何执行此操作的信息。

下面是确认我的话的日志。

第一次请求:

03:12:06,643 DEBUG headers:135 - http-outgoing-0 >> CONNECT t.myhost.com:443 HTTP/1.1
03:12:06,643 DEBUG headers:138 - http-outgoing-0 >> Host: t.myhost.com
03:12:06,643 DEBUG headers:138 - http-outgoing-0 >> User-Agent: Apache-HttpClient/4.5.2 (Java/1.8.0_45)

03:12:06,793 DEBUG headers:124 - http-outgoing-0 << HTTP/1.1 407 Proxy Authentication Required

03:12:06,794 DEBUG headers:127 - http-outgoing-0 << Proxy-Connection: close

//然后重试包含Proxy-Authorization标题

的请求

03:12:06,795 DEBUG HttpAuthenticator:107 - 162.243.116.56:71223 requested authentication

03:12:07,305 DEBUG ProxyAuthenticationStrategy:227 - Caching 'basic' auth scheme for http://162.243.116.56:71223 

这是我的代码(它是Scala,但很容易阅读):

val credProvider = {
  val provider = new BasicCredentialsProvider()
  provider.setCredentials(AuthScope.ANY,
    new UsernamePasswordCredentials("myUser", "myPass"))
  provider
}

val connManager = {
  val mngr  = new PoolingHttpClientConnectionManager()
  mngr.setDefaultMaxPerRoute(Integer.MAX_VALUE)
  mngr.setMaxTotal(Integer.MAX_VALUE)
  mngr
}

val client = HttpClients.custom()
  .setConnectionManager(connManager)
  .disableRedirectHandling()
  .setDefaultCredentialsProvider(credProvider)
  .setProxy(new HttpHost(162.243.116.56, 71223 ))
  .build()

     val requestConfig = RequestConfig.custom()
       .setConnectTimeout(30000)
       .setConnectionRequestTimeout(30000)
       .build()


     val request = new HttpGet(url)
     request.setConfig(requestConfig)
     val response = client.execute(request)

如何解决此问题(导致客户端始终发送Proxy-Authorization)?

答案 0 :(得分:0)

我不确定它是否是同一个问题,但是对于版本4.5.2,SPN(HTTP / some @ somerealm)和https:HTTPCLIENT-1712引入了一个错误(评论是特别有趣,因为它们显示了所发生事件的历史。

切换到版本4.5.1应解决它(如果这是同样的问题)
