"HttpSetProxy" is capable to make proxy authenticated by setting a user name and the password.

However,when sending http request using winhttp's functions, how to make the proxy authenticated?

This is the code I use.

#include-once
#include "winhttp.au3"
Global Const $tagWINHTTP_PROXY_INFO = "DWORD  dwAccessType;ptr lpszProxy;ptr lpszProxyBypass;"

;~  #FUNCTION# ;===============================================================================

;~  函数名...........: _WinHTTP_GetRespond
;~  描述.............: 完整的HTTP传输过程
;~  函数用法.........: _WinHTTP_GetRespond($hRequest, $ConnectURL [, Mode[，$hTimeOut[，$Context[，$Cookies[，$MoreHeader[，$ProxyServer[, $FuncName[, $ParamArray]]]]]]]])
;~
;~  参数解释.........: $hRequest - 由 _WinHttpOpen() 函数返回的句柄 或 字符串 (Agent 的描述，也可使用-1,Dafult来创建默认描述)
;~                  $ConnectURL - 请求的URL地址，其形式可为 http://UserName:UserPassWord@127.0.0.1:8181/winhttp_getrespondUpdate/
;~                  $Mode - 本函数定义的模式:
;~                              0    GET (默认)
;~                              1    POST
;~                              2    返回服务器返回的内容(禁用检测的话，+256)
;~                              4    返回完整的Header
;~                              8    禁用重定向
;~                              16   禁用SSL的证书检测
;~                              32   使用自定义函数后立即返回
;~                              64   返回Connection句柄(即不关闭Connection句柄)
;~                              128  访问地址为'[0x00000]' + 'http://' 的形式(即使用Connection句柄作为当期连接)
;~                              256  返回内容绝对为二进制
;~                  $hTimeOut       - 超时MS(正整数,或一维四元数组)
;~                  $Context        - 请求需要发送的内容，一般用于POST中        (字符串)
;~                  $Cookies        - 指定文件头 Cookies (字符串)
;~                  $MoreHeader     - 指定更多的文件头信息 (单一字符串,字符串内可包含回车符)
;~                  $ProxyServer    - 代理服务器地址 xx.xx.xx.xx:xx (字符串)
;~                  $FuncName       - 用户自定义过程名称 (执行时机为确定请求有效后，优先于本过程的文件头及数据获取过程)
;~                  $ParamArray     - 用户自定义过程所需参数构成的数组
;~
;~   函数返回值......: 如果成功的话 - 返回一维8元的数组
;~                            0        -        数据内容                ( 二进制的字符串或字符串，要强制使用二进制模式，请使用256模式，并根据需要使用 Binary() 或 BinarytoString() 函数 )
;~                            1        -        服务器状态
;~                            2        -        文件长度
;~                            3        -        Cookies
;~                            4        -        重定向       （该重定向为完整的URL地址)
;~                            5        -        编码类型
;~                            6        -        完整Header
;~                            7        -        Connection 句柄
;~                         (无内容时，上述任何一个元素均可能为-1)

;~                  如果失败的话 - 设置@error，返回最后的错误代码:
;~                      @Error:
;~                          1        -        打开请求失败
;~                          2        -        打开请求失败或无法设置重定向
;~                          4        -        无法发送请求
;~                          5        -        服务器无回应或超时或使用SSL验证
;~  作者 ............: Republican
;~  注意点 ..........: 如果Header为多行数据，请使用@CRLF为每行非开

Put your script in SciTE, translate the comments to english because they might help in understanding your script, run Tidy (CTRL-t) and Syntax check (CTRL-F5) on it until there are no errors, then post on the forum using [code][/code] tags (angle brackets in the toolbar just above the forum edit window).

You'll get more help if you take some effort to make your code readable to those who might like to.
