如何在 defaultProxy 配置设置中传递凭据? [英] How to pass credentials in defaultProxy config setting?

问题描述

客户端无法使用我的 webpart，因为他在代理服务器后面，他们需要指定用户名和密码才能通过代理.我现在在我的配置文件中有这个:

A client is unable to use my webpart because he is behind a proxy server and they need to specify a username and password to get past the proxy. I have this in my config file right now:

<system.net>
    <defaultProxy>        
      <proxy usesystemdefault="False" proxyaddress="http://127.0.0.1:8888" bypassonlocal="True"   />
    </defaultProxy>
  </system.net>

有没有办法为此代理设置提供用户名和密码?

Is there a way to supply a username and password to this proxy setting?

推荐答案

我不知道有什么方法可以在 web.config 的 defaultProxy 部分执行此操作，但您绝对可以从代码中执行此操作.试试这个:

I'm not aware of a way to do this in defaultProxy section of web.config, but you can definitely do it from code. Try this:

// Get proxy server info from AppSettings section of Web.Config
var proxyServerAddress = ConfigurationManager.AppSettings[ "proxyServerAddress" ];
var proxyServerPort = ConfigurationManager.AppSettings[ "proxyServerPort" ];

// Get proxy with default credentials 
WebProxy proxy =new WebProxy(proxyServerAddress, proxyServerPort);
proxy.Credentials = System.Net.CredentialCache.DefaultCredentials();

Web.Config(配置部分):

Web.Config (configuration section):

<appSettings>
  <add key="proxyServerAddress" value="proxy.myhost.com" />
  <add key="proxyServerPort" value="8080" />
</appSettings>

然后将 proxy 分配给您在 webPart 中使用的 webClient.

And then assign proxy to the webClient you are using in your webPart.

如果我做更多的功课，我就会意识到您的问题可以通过一个属性解决:useDefaultCredentials="true"

If I had done more homework, I would have realized your problem could have been fixed with one attribute: useDefaultCredentials="true"

<system.net>  
    <defaultProxy useDefaultCredentials="true"> 
        <proxy usesystemdefault="False" proxyaddress="http://127.0.0.1:8888" bypassonlocal="True" />  
    </defaultProxy>  
</system.net>
