如何将Cookie添加到WebRequest？

Question

我试图对一些代码进行单元测试,我需要替换它:

  HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create( uri );
  httpWebRequest.CookieContainer = new CookieContainer();

同

  WebRequest webRequest = WebRequest.Create( uri );
  webRequest.CookieContainer = new CookieContainer(); 

基本上,如何在不使用HttpWebRequest的情况下将cookie添加到请求中？

Answer 1

根据您的意见,您可以考虑编写扩展方法:

public static bool TryAddCookie(this WebRequest webRequest, Cookie cookie)
{
    HttpWebRequest httpRequest = webRequest as HttpWebRequest;
    if (httpRequest == null)
    {
        return false;
    }

    if (httpRequest.CookieContainer == null)
    {
        httpRequest.CookieContainer = new CookieContainer();
    }

    httpRequest.CookieContainer.Add(cookie);
    return true;
}

然后你可以有如下代码:

WebRequest webRequest = WebRequest.Create( uri );
webRequest.TryAddCookie(new Cookie("someName","someValue"));

Answer 2

尝试这样的事情：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.contoso.com/default.html");
request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(new Cookie("ConstoCookie", "Chocolate Flavour"));

Answer 3

WebRequest是一个没有CookieContainer属性的抽象类.此外,您不能使用Headers集合(未实现的异常),因此任何类似webRequest.Headers.Add("Cookie","...")的尝试都将失败.

抱歉,您没有机会在WebRequest中使用Cookie.

坚持使用HttpWebRequest并使用其Headers集合添加/编辑您喜欢的多个Cookie!
