调用并运行 doPost

Question

是否可以调用同一个项目中存在的doPost。当我在同一个项目中调用 doPost 时，我得到一个 200 响应代码，但是如果我让其他人使用运行相同的函数，他们会得到一个 500 响应代码。我正在使用 dev URL，以我的身份执行应用程序，我域中的任何人都可以访问该应用程序。这是我的 sample file.

function sendPost(){
  var sheetURL = SpreadsheetApp.getActiveSpreadsheet().getUrl();
  
  var webAppUrl = "<<my dev url>>"; //insert webapp URL of Dev or Exe script file
  
  var auth = ScriptApp.getOAuthToken();
  var header = { 'Authorization': 'Bearer ' +  auth};
  var payload = {scriptName : 'updateDataV2', sheetURL : sheetURL};
  var options = { 
    method : 'post',
    headers : header,
    muteHttpExceptions : true,
    payload : payload
  };
  
  var resp = UrlFetchApp.fetch(webAppUrl, options);
  Logger.log(resp.getResponseCode());
  
  var message = resp.getResponseCode() == 200 ? 'Database update complete' : 'There seems to be an issue. Please try again.';
  //if(resp.getResponseCode() == 200){resetFormulas();}
  return SpreadsheetApp.getActiveSpreadsheet().toast(message);
  
//Below 2 lines needed to setup access
//DriveApp.getFiles();
//DriveApp.createFile(blob);
}

function doPost(e){
  if(!e.parameters.scriptName){return ContentService.createTextOutput('A function name must be passed in a payload to run.');};
  
  Logger.log('parameters from caller ' + JSON.stringify(e));
  
  var newText = this[e.parameters.scriptName](e); //This line runs the function being called with parameters
  
  return ContentService.createTextOutput(newText);
}

这是给用户的错误信息。

Answer 1

好的。

我调试了你的代码。我看到了下一行。

var newText = this[e.parameters.scriptName](e);

很有意思。当您调用不同用户的网络应用程序时，它也可能指向不同的东西。

在这种情况下不要使用 this。尝试将其覆盖为字典或 IIFE。简而言之，您应该确保您的函数想要运行的所有代码都已经初始化。这在当前上下文中不起作用。

我复制了文件然后注释了下一行

// var newText = this[e.parameters.scriptName](e);

然后我重新发布了该应用程序，现在它可以正常工作了。

额外

您需要为所有授权用户发布应用程序
