从TWebBrowser获取Cookie [英] Getting Cookie from TWebBrowser

问题描述

尝试使用indy下载文件，（通过asp保存excel响应），但遇到错误，使用wireshark请求丢失了cookie。

Trying to download a file using indy,(post to asp save the excel response) but running into errors, using wireshark the request is missing cookies.

尝试

var
document: IHTMLDocument2;
cookies:tstringlist;
begin
cookies:=tstringlist.Create;
document := WebBrowser1.Document as IHTMLDocument2;

//do stuff with them
end;

什么都不返回，从twebbrowser中提取cookie（或2）的最佳方法是什么？

returns nothing, whats the best way to extract a cookie(or 2) out of twebbrowser, or is there something better i'm missing?

推荐答案

TWebBrowser 是包装器吗？ Internet Explorer，它本身就是WinInet的包装。 Indy不与IE / WinInet共享cookie，因此您必须手动将cookie详细信息复制到Indy的 TIdCookieManager 组件中。但是， IHTMLDocument2.cookie 属性只是 name = value 对的分隔字符串（如果它返回任何内容） ，由于安全性限制），其中包含的信息不足以供Indy使用，例如cookie的源URL和目标域/路径，因此您必须从其他地方获取该信息，例如通过解析IE存储的cookie文件在Windows的 Cookies 文件夹中。

TWebBrowser is a wrapper around Internet Explorer, which itself is a wrapper around WinInet. Indy does not share cookies with IE/WinInet, so you have to copy the cookie details manually into Indy's TIdCookieManager component. However, the IHTMLDocument2.cookie property is just a delimited string of name=value pairs (if it returns anything at all, due to security restrictions), which does not contain enough information for Indy's use, such as a cookie's source URL and target domain/path, so you have to get that information from somewhere else, such as by parsing IE's cookie files that are stored in Windows' Cookies folder.
