当URL作为参数传递时，UrlFetchApp.fetch会引发错误

时间：2015-10-28 10:00:12

标签： google-apps-script

如果我有以下代码：

function apiGET(someUrl){
  var result = UrlFetchApp.fetch(someUrl);
  return result
}

result = apiGET("https://www.google.com")
Logger.log(result)

我收到以下错误：DNS error: http://undefined (line 2, file "")

但是日志显示HTML正在按预期返回。

如果我直接将fetch（）方法传递给字符串，我不会收到错误并返回相同的HTML。

function apiGET(someUrl){
  var result = UrlFetchApp.fetch("https://www.google.com");
  return result
}

result = apiGET("https://www.google.com")
Logger.log(result)

将字符串作为参数传递，直接传递字符串有什么区别？

第一个功能的HTML是：

答案 0 :(得分：2)

在GAS调用函数中，globablly并不能很好地工作，你不能这样做，如果你从另一个函数传递它，它可以正常工作：

function apiGET(someUrl){
  var result = UrlFetchApp.fetch(someUrl);
  return result
}

function runTest(){
  result = apiGET("https://www.google.com")
  Logger.log(result)
}
