使用Javascript的Google Drive API多部分/混合批处理请求的正确格式

我正在使用Javascript（在GoogleApps脚本编辑器中）向GoogleDriveAPI发出HTTP请求

我已经成功地对API进行了单独的调用，所以我知道我的Oauth 2可以工作，但现在我正在进行批处理请求

我将循环遍历每个文件，并对每个文件进行2次API调用

我的请求：

var newOwnerEmail = 'archive@test.com';
var newEditorEmail = 'admin@test.com';
var fileIds = ['a', 'b', 'c'];

const boundary = 'testboundaryname';
const delimiter = "\r\n--" + boundary + "\r\n";
const close_delim = "\r\n--" + boundary + "--";

var multipartRequestBody = '';

for (var i = 0; i < fileIds.length; i++) {

  var fileId = fileIds[i];

  var resource1 = { role: "owner", type: "user", value: newOwnerEmail };

  var requestBody = {};
  requestBody.path = '/drive/v2/files/' + fileId + '/permissions';
  requestBody.method = 'POST';
  requestBody.contentType = 'application/json';
  requestBody.payload = JSON.stringify(resource1);
  requestBody.muteHttpExceptions = true;

  multipartRequestBody += delimiter;
  multipartRequestBody += 'Content-Type: application/json\r\n';
  multipartRequestBody += JSON.stringify(requestBody);

  var resource2 = { role: "writer", type: "user", value: newEditorEmail };

  requestBody.payload = JSON.stringify(resource2);

  multipartRequestBody += delimiter;
  multipartRequestBody += 'Content-Type: application/json\r\n';
  multipartRequestBody += JSON.stringify(requestBody);

}

multipartRequestBody += close_delim;

var batchUrl = 'https://www.googleapis.com/batch';

var batchRequestBody = {};
batchRequestBody.headers = { Authorization: 'Bearer ' + service.getAccessToken() };
batchRequestBody.method = 'POST';
batchRequestBody.contentType = 'multipart/mixed; boundary="' + boundary + '"';
batchRequestBody.body = multipartRequestBody;
batchRequestBody.muteHttpExceptions = true;

try {

  var batchResponse = UrlFetchApp.fetch(batchUrl, batchRequestBody);

  Logger.log(batchResponse);

我运行了

UrlFetchApp.getRequest（）

查看发送到服务器的内容，如下所示：

{
  "headers": {
    "Authorization": "Bearer xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "X-Forwarded-For": “(our external IP address)“
  },

  "payload": "\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"owner\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"archive@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"writer\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"admin@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"owner\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"archive@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"writer\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"admin@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"owner\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"archive@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"writer\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"admin@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"owner\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"archive@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"writer\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"admin@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"owner\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"archive@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary\r\nContent-Type: application/json\r\n{\"method\":\"POST\",\"contentType\":\"application/json\",\"payload\":\"{\\\"role\\\":\\\"writer\\\",\\\"type\\\":\\\"user\\\",\\\"value\\\":\\\"admin@test.com\\\"}\",\"muteHttpExceptions\":false}\r\n--testboundary--",

}

我得到的答复是：

Unsupported number format: --

请求的内容肯定有问题，但很难确定它是什么，因为使用Javascript创建批处理请求的文档太少了

我能找到的唯一文档是，但示例是独立于语言的/假设的

---

然后我发现，它似乎使用了一个GoogleAPI客户端库，我不能在应用程序脚本中使用它

哎呀！抱歉，我不知道建议的编辑是什么，然后我看到它被拒绝了，但我意外地批准了它。我添加了javascript标记，因为我觉得在本例中澄清我使用的是javascript很重要，因为googleapi的官方文档通常只有Python、Ruby、Java等的示例代码，但很少有javascript。在我的情况下，我需要能够使用Javascript，我很难解决这个问题，因为在互联网上几乎没有关于我尝试做什么的例子或类似问题；显示UrlFetchApp.getRequest的输出？输出在上面-我写下“我得到这个响应：”（错误请求

和
错误400
）的部分，我指的是getRequest结果。它会显示你发出的请求的详细信息。我不需要再弄清楚这一点，谷歌今天刚刚发布了一个。
