Question

我的网站是由ASP.NET MVC 3编写的，并且在IIS 7.5上托管以解决CORS问题，我需要添加自定义标题。

我按照此链接中的步骤http://msdn.microsoft.com/en-us/library/bb763179%28v=vs.100%29.aspx但是将这些行添加到Web.Config文件将导致以下错误

  <system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="CustomHeader" value="CustomHeader" />
      <customHeaders>
    </httpProtocol>
  </system.webServer>

错误

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

由于我的网络配置中已存在<system.webServer>标记，因此我尝试将内容添加到现有标记并单独添加，但两者都无效。

任何帮助将不胜感激。

的Web.Config

Answer 1

我找到了解决方案，

在IIS中，我删除了X-Powered-By标题，现在一切正常。

Answer 2

在配置文件的自定义标头部分下使用以下标记

$.ajax({
            url: '/setSession',
            type: 'POST',
            Accept : 'application/json',
            //contentType: 'application/json',
            dataType: 'json',
            data: { "hello": templateName}, 
            //data: JSON.stringify({ "hello": templateName}), 
            headers: {
               'Authorization': 'Bearer '+ token
            },
            success: function (result) {console.log('post ok'+JSON.stringify(result));
                // CallBack(result);
            },
            error: function (error) { console.log('post failed'+JSON.stringify(error));
         
            }
         });

在Web配置中添加<customheaders>将导致错误500内部服务器错误</customheaders>
