HttpWebRequest的：添加cookie来的CookieContainer - > ArgumentException的（参数名称：cookie.Domain） [英] HttpWebRequest: Add Cookie to CookieContainer -> ArgumentException (Parametername: cookie.Domain)

问题描述

我想通过我的应用程序登录到网站。
我做了什么：

I'm trying to login to a website via my application. What I did:

首先，我想通了浏览器如何与小提琴手授权过程。
我检查了POST请求是如何构建的，我试图重建它。
中的浏览器发送4饼干（谷歌分析），我试图让它们：

First I figured out how the browser does the authorization process with Fiddler. I examined how the POST request is built and I tried to reconstruct it. The browser sends 4 cookies (Google Analytics) and I tried to set them:

CookieContainer gaCookies = new CookieContainer();
gaCookies.Add(new Cookie("__utma", "#########.###########.##########.##########.##########.#"));
gaCookies.Add(new Cookie("__utmb", "#########.#.##.##########"));
gaCookies.Add(new Cookie("__utmc", "#########"));
gaCookies.Add(new Cookie("__utmz", "#########.##########.#.#.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)"));

（刚刚替换＃原来的cookie数据）

(just replaced the original cookie data with #)

然后，我通过与调试代码去了，只要第一gaCookies.Add执行，应用程序与

Then I went through the code with the debugger and as soon as the first gaCookies.Add is executed, the application stops with an

System.ArgumentException: The parameter '{0}' cannot be an empty string. Parameter name: cookie.Domain

我想知道为什么会这样。 Cookie的构造函数不需要域名，我不知道在哪里可以得到这个值？

I would like to know why this happens. The constructor of Cookie doesn't require a domain and I don't know where I can get this value?

将是非常巨大的，如果你有人可以帮助我这一点。结果
我不是一个webdeveloper或网页内容方面的专家，所以我不很了解。结果
也许有一个伟大的来源在那里我可以了解这个如果没有短，快回答？结果

Would be very great if someone of you could help me with this.
I'm not a webdeveloper or an expert in web stuff so I don't know much about it.
Is there maybe a great source where I can learn about this if there is no "short and quick answer"?

推荐答案

的CookieContainer s时，可以容纳多个Cookie为不同的网站，为此标签（域）必须提供给每个cookie来每个网站绑定。域可以实例化具体Cookie像时可以设置这样：

CookieContainers can hold multiple cookies for different websites, therefor a label (the Domain) has to be provided to bind each cookie to each website. The Domain can be set when instantiating the individual cookies like so:

Cookie chocolateChip = new Cookie("CookieName", "CookieValue") { Domain = "DomainName" };

一个简单的方法抢域名就是让乌里（如果你不使用的话）包含您的目标URL，并设置使用 Uri.Host 属性中的cookie的域。

An easy way to grab the domain to is to make a Uri (if you aren't using one already) that contains your target url and set the cookie's domain using the Uri.Host property.

CookieContainer gaCookies = new CookieContainer();
Uri target = new Uri("http://www.google.com/");

gaCookies.Add(new Cookie("__utmc", "#########") { Domain = target.Host });
