google apps脚本==> UrlFetchApp，方法GET和Cookie [英] google apps script ==> UrlFetchApp, method GET and cookie

问题描述

我使用UrlFetchApp发送用户和pwd（方法POST）。获得cookie后，并在其他请求（方法GET）中使用。但是这个新请求不起作用，我认为这个cookie在这个新请求中没有正确使用。有人可以帮我吗？

I use the UrlFetchApp to send the user and pwd (method POST). After get the cookie, and use in other request (method GET). But this new request not working, I think that this cookie not has correct use in this new request. Can anyone help me?

  var opt ={
    "method":"post",
    "User-Agent" : "Mozilla/5.0",
    "Accept" : "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
    "Accept-Language" : "en-US,en;q=0.5",    
    "payload": this.payload.toString(), 
    "followRedirects" : false
  };
  var response = UrlFetchApp.fetch("https://edas.info/addTopic.php?c=19349",opt);
  var resp1=response.getContentText();    
  Logger.log(resp1);  
  response.getResponseCode();

  var headers = response.getAllHeaders();
  var cookies = headers['Set-Cookie']; 
  for (var i = 0; i < cookies.length; i++) {
    cookies[i] = cookies[i].split( ';' )[0];
  };


  opt = {
    "method" : "get",
    "User-Agent" : "Mozilla/5.0",
    "Accept" : "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
    "Accept-Language" : "en-US,en;q=0.5",    
    "headers": {
      "Cookie": cookies.join(';')
    },
    "followRedirects" : false    
  };
  response = UrlFetchApp.fetch("https://edas.info/addTopic.php?c=19349", opt);
  var resp1=response.getContentText();  
  Logger.log(resp1);  

推荐答案

首先，谢谢您的代码片段，这使我开始使用这种脚本处理Cookie。我遇到了可能是您的问题的问题。有时网页返回一个cookie数组，然后您的代码可以正常工作。有时它返回一个字符串（而不是一个字符串的数组）。因此，我不得不消除以下测试的歧义：

First off, thanks you for the snippet of code, this got me started with processing cookies in such script. I encountered an issue that was possibly your problem. Sometimes a Web page returns an array of cookies, and then your code works fine. Sometimes it returns a single string (instead of an array of one string). So I had to disambiguate with a test like:

if ( (cookies != null) && (cookies[0].length == 1) ) {
      cookies = new Array(1);              
      cookies[0] = headers['Set-Cookie']; 
}
