httpwebrequest 标头中多个 Set-Cookie 的问题

Question

我尝试使用 C# HTTPWebRequest 类登录 amazon.com，我可以登录，但无法读取标头中的多个 set-cookies

当服务器响应多个“Set-Cookie:”标头时，只有 可供我

第一个在标头HTTPWebRequest 中的 Web 响应 中

    Set-Cookie: x-main=Yvi4723B?Nk5zuPPCZ0?66eGEI5kVnOM; path=/; domain=.amazon.com; 
expires=Wed May 25 13:20:05 2011 GMT

使用 如何使用 HTTPWebRequest 类获取标头中的所有“Set-Cookie:”？

HTTP Live 标头中的 Web 响应

我认为您的意思是在 HttpWebResponse 对象中获取 Set-Cookie 标头；如果是这样，那么您可以使用 GetValues 方法来获取所有Set-Cookie 标头的实例。
