Delphi-从代码登录网页 [英] Delphi - logging in to webpage from code

问题描述

我正在使用Delphi 7，需要一些问题的帮助，是的，我到处都在寻找答案，但是所提供的代码没有记录在案，所以我不知道它是如何工作的或如何将其调整为符合我的需求.

I am using Delphi 7 and require some help with a problem, and yes, I have searched everywhere for an answer, yet the supplied code isn't documented , so I have no idea how it works or how to adjust it to fit my needs.

我要实现的目标是登录网站 http://kissanime.com/login ..

What I am trying to achieve is to log in to the website http://kissanime.com/login ..

我遇到的问题是，当我的程序在该网站的HTML上执行某些工作时，我需要保持登录状态(基本上，我想解析某个系列的下载链接，但是我需要登录到查看所说的链接)...

The problem I'm experiencing is that I need to stay logged in while my program does some work on that website's HTML ( Basically I want to parse out the download links of a certain series, but I need to be logged in to view said links )...

我没有可以提供的代码，因为我在寻找解决方案时看到的代码都没有多大意义，但是，我对需要完成的工作有所了解.我认为，使用某种POST方法在网站上为其提供用户名和密码将是一个开始，从那以后，我不确定是否要保持登录状态.

I have no code that I can supply as none of the code that I saw while searching for a solution didn't make much sense, however, I have an idea of what needs to be done. I think that using some POST method to the website to supply it with the username and password would be a start, from there on out, I'm not sure whether or not I'd stay logged in.

我可能使这个问题复杂化了，也许有一个简单的方法可以解决这个问题，这就是为什么我转向一个通常可以得到所有答案的站点的原因，我希望我对问题进行了充分的解释并且我可以找到一些帮助..

I may be overcomplicating this problem and there is perhaps a simple way of achieving this, and that is why I have turned to the one site that I usually get all my answers from, I hope that I explained the problem well enough and that I can find some help..

我不要指望源代码，因为我在这里没有提供任何源代码，但是即使是一些可以向我解释此过程的有用链接也将不胜感激.

I Do not expect source code , since I did not supply any here, but even some useful links that could explain this process to me would be much appreciated.

在这里，我创建了一个简单的图像拼贴，以巩固我对问题的解释:

Here I have created a simple collage of images to just solidify my explanation of the problem :

谢谢您的时间，希望我能在这个问题上找到一些清晰的认识！

Thank you for your time and I hope that I can find some clarity on this subject!

推荐答案

您需要先Get()包含该Webform的网页，并使其生成所需的任何cookie，然后让TIdHTTP捕获它/它们(如果您没有将TIdCookieManager附加到TIdHTTP.CookieManager属性，TIdHTTP在内部创建了TIdCookieManager)，则可以将所需的Webform数据提交到适当的网页，并且TIdHTTP将包括任何相关的cookie当前持有的(s).例如:

You need to first Get() the webpage that contains the webform and let it generate whatever cookie(s) it needs, and let TIdHTTP capture it/them (if you do not attach a TIdCookieManager to the TIdHTTP.CookieManager property, TIdHTTP creates a TIdCookieManager internally), then you can submit the desired webform data to the appropriate webpage and TIdHTTP will include any relevant cookie(s) it is currently holding. For example:

// get cookies first...
IdHTTP1.Get('http://kissanime.com/login');

// now submit the webform...
Params := TStringList.Create;
try
  Params.Add('username=' + UserName);
  Params.Add('password=' + Password);
  Params.Add('chkRemember=1'); // <-- omit this if you do not want to enable the webform's "Remember me" option
  Params.Add('btnSubmit=');
  Params.Add('redirect=');

  IdHTTP1.Post('http://kissanime.com/login', Params);
finally
  Params.Free;
end;
