如何在身份验证代理的后面使用HTTPBuilder

问题描述

我尝试了2个小时，但无法完成工作。
这就是我所做的：
$ b $ ol <

  grails add-proxy myproxy主机=<宿主gt;中--port = LT;端口> 中--username =<用户名> 中--password = LT; PSW> 中
 grails使用代理myproxy 
  

我得到了连接拒绝错误，这代表代理不工作在我的groovy文件中，我添加了代理

  def http = new HTTPBuilder（http：// http：//headers.jsontest.com/）
 http.setProxy（host，port，http）; 
 http.request（Method.GET，JSON）{
 uri.path ='/'
 response.success = {resp，json  - > 
 ..... 
} 
} 
  

然后我获取groovyx.net.http.HttpResponseException：需要代理验证

我无法弄清楚如何设置用户/ psw for the proxy to make work

我尝试了java方式，不工作

  System.setProperty（http.proxyUser，username）; 
 System.setProperty（http.proxyPassword，password）; 
  

和

  Authenticator.setDefault（new Authenticator（）{
 protected PasswordAuthentication getPasswordAuthentication（）{
 return new PasswordAuthentication（username，.toCharArray（））; 
}}）; 
  

有谁知道如何做到这一点？

解决方案

不知道它是否可行，但有一些代码是在这里显示你应该这样做：

  import groovyx.net.http。* 
 import static groovyx.net.http.ContentType。* 
 import static groovyx.net.http.Method。* 
 import org.apache.http.auth。* 
 
 def http = new HTTPBuilder（'http://www.ipchicken.com'）
 
 http.client.getCredentialsProvider（）。setCredentials（
 new AuthScope（myproxy.com，8080），
 new UsernamePasswordCredentials（proxy-username，proxy-password）
）
 
 http.setProxy（'myproxy.com'，8080，'http'）
 
 http.request（GET，TEXT）{req  - > 
 response.success = {resp，reader  - > 
 printlnResponse：$ {reader.text}
} 
} 
  

I tried 2 hours and could not make it work.This is what I did:

1. grails add-proxy myproxy "--host=<host>" "--port=<port>" "--username=<username>" "--password=<psw>"
   grails use-proxy myproxy
   

   I got connection refused error which mean the proxy is not working

2. In my groovy file, I add the proxy

   def http = new HTTPBuilder("http://http://headers.jsontest.com/")
   http.setProxy(host, port, "http");
   http.request(Method.GET, JSON) {
       uri.path = '/'
       response.success = { resp, json ->
                       .....
       }
   }
   

   I then get groovyx.net.http.HttpResponseException: Proxy Authentication Required

I could not figure out how I set the user/psw for the proxy to make it work

I tried the java way, not working

    System.setProperty("http.proxyUser", username);
    System.setProperty("http.proxyPassword", password);

and

    Authenticator.setDefault(new Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, .toCharArray());
    }});

Does anyone know how to do this?

解决方案

Don't know if it will work, but there's some code over here that shows you should do:

import groovyx.net.http.*
import static groovyx.net.http.ContentType.*
import static groovyx.net.http.Method.*
import org.apache.http.auth.*

def http = new HTTPBuilder( 'http://www.ipchicken.com'  )

http.client.getCredentialsProvider().setCredentials(
    new AuthScope("myproxy.com", 8080),
    new UsernamePasswordCredentials("proxy-username", "proxy-password")
)

http.setProxy('myproxy.com', 8080, 'http')

http.request( GET, TEXT ){ req ->
    response.success = { resp, reader ->
        println "Response: ${reader.text}"
    }
}
