HANDELING饼干和标题与agilitypack C＃

问题描述

agilitypack确实非常出色，我在HTML解析，但对于其他HTML方面？对象agilitypack.HtmlWeb允许访问cookie和头？

agilitypack does excellent job for me in html parsing,but what about other html aspects?the object agilitypack.HtmlWeb allow access to cookies and headers?

推荐答案

访问cookie和头可以通过 HtmlWeb。preRequest获得和 HtmlWeb.PostResponse 处理程序。执行HTTP请求之前出现的第一个。一个HTTP请求已经被执行后，会出现第二个。要使用cookie，你应该通过设置 HtmlWeb.UseCookies 属性启用一个 HtmlWeb 实例真正的。

Access to the cookies and headers could be obtained through HtmlWeb.PreRequest and HtmlWeb.PostResponse handlers. The first one occurs before an HTTP request is executed. The second one occurs after an HTTP request has been executed. To use cookies you should enable it for an HtmlWeb instance by setting HtmlWeb.UseCookies property to true.

下面是一个例子：

var web = new HtmlWeb { UseCookies = true };
web.PreRequest += request =>
{
    // gets access to the cookie container
    var cookieContainer = request.CookieContainer;
    //  gets access to the request headers
    var headers = request.Headers;
    return true;
};
web.PostResponse += (request, response) =>
{
    // response headers
    var headers = response.Headers;
    // cookies
    var cookies = response.Cookies;
};
