在Web浏览器控件设置代理凭证 [英] Set Proxy Credential in Web Browser Control

问题描述

我工作的一个遗留code其中一个应用程序使用 AxSHDocVw.AxWebBrowser （不可以 系统。 Windows.Forms.Control ）打开网页，我延长其采取代理到考虑。

I am working on a legacy code where an application uses AxSHDocVw.AxWebBrowser (not System.Windows.Forms.Control) to open up web pages and am extending it to take proxy into considerations.

我已经在 http://www.pinvoke.net/default下面的例子的.aspx / WININET / internetsetoption.html 使用 InternetSetOption（）要经过指定的代理和测试，它的作品。

I have following example on http://www.pinvoke.net/default.aspx/wininet/internetsetoption.html to use InternetSetOption() to go through specified proxy and tested that it works.

现在的障碍是我什么都试过，但未能通过用户名和密码之后code：

Now the hurdle is I tried everything but failed to pass username and password with following code:

//-- Set Proxy Username
bool resultF = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY_USERNAME, username, username.Length+1);
var errorF = Marshal.GetLastWin32Error();

//-- Set Proxy Password
bool resultG = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY_PASSWORD, password, password.Length+1);
var errorG = Marshal.GetLastWin32Error();

两个 resultF 和 resultG 返回真并具有没有错误，但它仍在工作。对那些原本可以在这里发生的任何提示？做什么方法我一定要调试吗？

Both resultF and resultG return true and has no errors but it still working. Any hint on what may be happening here? and what method do I have to debug this?

在此先感谢。

推荐答案

其实，我发现了一个work'able的解决方案，它是在导航谎言与代理服务器的身份验证标头：

I actually found a work'able solution, where it was lie under navigation with Proxy-Authentication in header:

var credentialStringValue = "user:pass";
var credentialByteArray = ASCIIEncoding.ASCII.GetBytes(credentialStringValue);
var credentialBase64String = Convert.ToBase64String(credentialByteArray);

Object nullObject = 0;
Object nullObjectString = "";
Object authObject = string.Format("Proxy-Authorization: Basic {0}{1}", credentialBase64String, Environment.NewLine);

browser.Navigate(args.Url, ref nullObject, ref nullObject, ref nullObjectString, ref authObject);

其中，浏览器是：

public AxWebBrowser browser;
