我有一个 Google Apps 脚本来与外部程序通信。该程序需要身份验证来进行身份验证：

“应该使用POST方法，并且内容类型应该设置为“application/x-www-form-urlencoded”。用户名应该在参数“ UserName ”中给出，密码应该在参数中给出“密码”。所以发布数据将类似于“用户名=xxx&密码=yyy”。请记住，当不发送每个请求的用户名和密码时，应该保留会话（或保留它的对象）活。”

这是有效的：

 var payload = "_UserName_="+username+"&_Password_="+password
 var options = {
 "method" : "POST",
 "payload" : payload,
 "contentType" : "application/x-www-form-urlencoded"
};

 var xml = UrlFetchApp.fetch("https://start.application.nl/docs/XMLDivisions.aspx",        options);

但在这里我想提出下一个要求：

  var xml = UrlFetchApp.fetch("https://start.application.nl/docs/XMLDownload.aspx?PartnerKey="+partnerKey+"&Topic=Accounts");

但未通过身份验证？

如何让 GAS 会话保持活动状态？

一个使用 PHP 的工作示例：

    <?php
$baseurl = "https://start.exactonline.nl";
$username = "<username>";
$password = "<password>";
$partnerkey = ""; /* If you have one, the partnerkey with or without curly braces */
$division = "<division code>";  /* Check the result of the first division retrieving for the division codes */
$cookiefile = "cookie.txt";
$crtbundlefile = "cacert.pem"; /* this can be downloaded from http://curl.haxx.se/docs/caextract.html */


/* Logging in */
$header[1] = "Cache-Control: private";
$header[2] = "Connection: Keep-Alive";

/* init, don't term until you're completely done with this session */
$ch = curl_init();

/* Set all options */
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);
curl_setopt($ch, CURLOPT_CAINFO, $crtbundlefile);
curl_setopt($ch, CURLOPT_POSTFIELDS, array("_UserName_"=>"$username", "_Password_"=>"$password"));

/* Retrieving divisions, the current should be the one in which the user worked the last time */
$url = "$baseurl/docs/XMLDivisions.aspx";
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);

/* Switching divisions */
$url = "$baseurl/docs/ClearSession.aspx?Division=$division&Remember=3";
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);

/* Retrieving divisions, the current should now be the one supplied in the switching divisions. This is only the current for this session! */
$url = "$baseurl/docs/XMLDivisions.aspx";
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);

/* Upload an xml file */
$topic = "Invoices";
$url = "$baseurl/docs/XMLUpload.aspx?Topic=$topic&PartnerKey=$partnerkey";
curl_setopt($ch, CURLOPT_URL, $url);
/* Send the xml along with the request */
$filename = "Invoices.xml";
$fp = fopen($filename, "r");
$xml = fread($fp, filesize($filename));
curl_setopt($ch, CURLOPT_POSTFIELDS, utf8_encode($xml));
$result = curl_exec($ch);

/* Finally close as we're finished with this session */
curl_close($ch);

echo $result;
?>

我想你错过了饼干。

尝试这样的事情：

var payload = "_UserName_="+username+"&_Password_="+password
 var options = {
 "method" : "POST",
 "payload" : payload,
 "contentType" : "application/x-www-form-urlencoded"
};

 var xml = UrlFetchApp.fetch("https://start.application.nl/docs/XMLDivisions.aspx",        options);

var cookie = response.getAllHeaders()['Set-Cookie'];

然后，将第二个请求中的 cookie 与其他准备好的标头一起发送。

var header = {'Cookie':cookie};
var opt = {"headers":header};

var xml = UrlFetchApp.fetch("https://start.application.nl/docs/XMLDownload.aspx?PartnerKey="+partnerKey+"&Topic=Accounts",opts);

我认为这应该可行，但有时服务器不仅需要 cookie 中的会话，还需要相同的 IP 地址发出请求，在这种情况下，谷歌 IP 有时会改变......
