我怎样才能获得IE凭证在我的代码中使用？ [英] How can i get IE credentials to use in my code?

问题描述

我目前正在开发使用 SpicIE 一个IE浏览器插件。

本插件做一些网页刮类似于发布MSDN上的例子：

 <$ C C>的WebRequest请求= WebRequest.Create（http://www.contoso.com/default.html）$; 
 
 request.Credentials = CredentialCache.DefaultCredentials; 
 
 HttpWebResponse响应=（HttpWebResponse）request.GetResponse（）; 
 
流数据流= response.GetResponseStream（）; 
 
 StreamReader的读者=新的StreamReader（数据流）; 
 
串responseFromServer = reader.ReadToEnd（）; 
 
 reader.Close（）; 
 dataStream.Close（）; 
 response.Close（）; 
  

然而，当我运行此代码我收到以下错误信息：

远程服务器返回错误：（407）代理身份验证

我目前正在使用代理服务器，并使用了的NetworkCredential 类手动提供我的网络凭据

  request.Credentials =新System.Net.NetworkCredential（名，密码，域）; 
  

但我仍然收到同样的错误。

即使我的问题解决了，我知道该插件的一些用户将使用代理服务器。

我想知道我怎么能得到IE浏览器证书，并用它在我的代码将其分配到request.Credentials 。

也许是这样的：

  request.Credentials = IE浏览器。的DefaultCredentials; 
  

解决方案

您所设置的凭据的网站的，但你需要的的代理的

设置的 request.Proxy.Credentials 。

（此外，使用使用语句响应/流/读取器而不是手动关闭它们，否则它们就会泄漏时。将抛出一个异常）

编辑：例如，要使用代理服务器的默认凭据，以及：

  request.Proxy.Credentials = CredentialCache.DefaultCredentials; 
  

I'm currently developing an IE plugin using SpicIE.

This plugin does some web scraping similar to the example posted on MSDN:

WebRequest request = WebRequest.Create ("http://www.contoso.com/default.html");

request.Credentials = CredentialCache.DefaultCredentials;

HttpWebResponse response = (HttpWebResponse)request.GetResponse ();

Stream dataStream = response.GetResponseStream ();

StreamReader reader = new StreamReader (dataStream);

string responseFromServer = reader.ReadToEnd ();

reader.Close ();
dataStream.Close ();
response.Close ();

However, when i run this code i receive the following error message:

The remote server returned an error: (407) Proxy Authentication Required.

I'm currently working behind a proxy server and used the NetworkCredential class to manually provide my network credentials

request.Credentials = new System.Net.NetworkCredential("name", "password", "domain");

but i still receive the same error.

Even if my problem is solved, i know that some users of the plugin will be behind a proxy server.

I want to know how i can get IE credentials and use it in my code to assign it to request.Credentials.

Maybe something like this:

request.Credentials = IE.DefaultCredentials;

解决方案

You're setting the credentials for the site, but you need credentials for the proxy.

Set request.Proxy.Credentials.

(Also, use using statements for the response/stream/reader rather than manually closing them, otherwise they'll leak when an exception is thrown.)

EDIT: For instance, to use the default credentials for the proxy as well:

request.Proxy.Credentials = CredentialCache.DefaultCredentials;
