如何在Google Apps脚本中使用UrlFetchApp发出Drive API批处理请求

问题描述：

我想知道如何使用Google Apps脚本中的UrlFetchApp发出Drive API批处理请求.我已经阅读了Google文档，但对我来说仍然不清楚.我想将下面的代码转换为接受多个文件ID的批处理请求.

I would like to know how to make a Drive API batch request with UrlFetchApp in Google Apps Script. I've read the google documentation but it still isn't clear to me. I want to convert the code below into a batch request accepting multiple file IDs.

var url = 'https://www.googleapis.com/drive/v2/files/FILEID/permissions';

var data = {
    "role":"owner",
    "type":"user",
    "value": NEWOWNER
  };

var response = UrlFetchApp.fetch(url, {
  headers: {
    Authorization: 'Bearer ' + AUTHORIZATIONTOKEN
  },
  method: 'post',
  contentType: 'application/json',
  payload: JSON.stringify(data),
});
var result = JSON.parse(response.getContentText());

我尝试使用https://www.googleapis.com/drive/v2/files?id=FILEID1&id=FILEID2/permissions，但似乎无法正常工作.我刚刚看到了将每个文件请求嵌套到批处理请求的描述，但是到目前为止，我还没有找到正确执行该请求的语法示例.

I tried using https://www.googleapis.com/drive/v2/files?id=FILEID1&id=FILEID2/permissionsbut it seemed to be not working. I just saw description of nesting each file request to a batch request, but so far I have not found a syntax example for doing it correctly.

一些见识会有所帮助.谢谢！

Some insight would be helpful. Thanks!

该示例脚本如何?当我看到此文档时，我发现您想要的API调用使用multipart/mixed发送批处理请求.这样，我可以为Google Apps脚本创建一个示例脚本，如下所示.

How about this sample script? When I saw this document, I could find that the API calls you want to do batch request are sent using multipart/mixed. By this, I could create a sample script for Google Apps Script as follows.

function myFunction() {
  var body = [
    {
      method: "POST",
      endpoint: "https://www.googleapis.com/drive/v3/files/### fileId 1 ###/permissions",
      requestBody: {
       "role": "owner",
       "type": "user",
       "emailAddress": NEWOWNER
      }
    },
    {
      method: "POST",
      endpoint: "https://www.googleapis.com/drive/v3/files/### fileId 2 ###/permissions",
      requestBody: {
       "role": "owner",
       "type": "user",
       "emailAddress": NEWOWNER
      }
    }
  ];

  var boundary = "xxxxxxxxxx";
  var contentId = 0;
  var data = "--" + boundary + "\r\n";
  for (var i in body) {
        data += "Content-Type: application/http\r\n";
        data += "Content-ID: " + ++contentId + "\r\n\r\n";
        data += body[i].method + " " + body[i].endpoint + "\r\n";
        data += body[i].requestBody ? "Content-Type: application/json; charset=utf-8\r\n\r\n" : "\r\n";
        data += body[i].requestBody ? JSON.stringify(body[i].requestBody) + "\r\n" : "";
        data += "--" + boundary + "\r\n";
  }
  var payload = Utilities.newBlob(data).getBytes();
  var options = {
    method: "post",
    contentType: "multipart/mixed; boundary=" + boundary,
    payload: payload,
    headers: {'Authorization': 'Bearer ' + ScriptApp.getOAuthToken()},
    muteHttpExceptions: true,
  };
  var res = UrlFetchApp.fetch("https://www.googleapis.com/batch", options).getContentText();
  Logger.log(res);
}

注意:

请针对您的环境修改此示例脚本.
如果需要更多API，请将元素添加到"body"数组中.
它假定您已经启用了Drive API.
Drive API在一个批处理请求中最多可使用100个调用.这是一个限制.
对于批处理请求，每个API调用都不保证有序.

Note :

Please modify this sample script for your environment.
If you want more APIs, please add the elements to the array of "body".
It supposes that you have already enabled Drive API.
Drive API can be used the maximum of 100 calls in one batch request. This is a limitation.
For the batch request, each API call is no guaranteed ordering.

在我的环境中，我确认这是可行的.但是，如果这在您的环境中不起作用，请告诉我.我想修改.

In my environment, I confirmed that this works. But if this didn't work in your environment, please tell me. I would like to modify.
