Google Drive API V3-推送通知 [英] Google Drive API V3 - Push Notifications

问题描述

自昨天早上以来，我一直在坚持使用Google云端硬盘API请求.

Since Yesterday morning I'm stuck with a google drive API request.

如此处所述: https://developers.google.com/drive/api /v3/push

我正尝试订阅发送此请求的通知:

I'm trying to subscribe to notifications sending this request :

网址: https://www.googleapis.com/drive/v3/changes /watch

Header :
Content-type: application/json
Authorization: Bearer my_auth_token

{
"id":"An ID generated",
"type":"web_hook",
"address":"my callback address",
}

响应是带有此正文的代码400:

The response is a code 400 with this body :

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "required",
    "message": "Required parameter: pageToken",
    "locationType": "parameter",
    "location": "pageToken"
   }
  ],
  "code": 400,
  "message": "Required parameter: pageToken"
 }
}

此订阅请求并非必需此参数，而是此请求(相同的URL.): https://developers.google.com/drive/api/v3/reference/changes/watch

This parameter isn't required according for this subscription request but for this one (same url..) : https://developers.google.com/drive/api/v3/reference/changes/watch

我丢失/误解了什么吗?文档是否存在问题?

Am I missing / misunderstanding something or is there a problem with the documentation ?

谢谢

推荐答案

pageToken参数是用于在下一页继续上一个列表请求的令牌.如我们所见，

The pageToken parameter is the token for continuing a previous list request on the next page. This should be set to the value of 'nextPageToken' from the previous response or to the response from the getStartPageToken method, as we see here.

因此，您应该将pageToken作为参数传递给URL:

Therefore, you should pass the pageToken as a parameter to your URL:

网址:https://www.googleapis.com/drive/v3/changes/watch?pageToken=[YOUR_PAGE_TOKEN_NUMBER_HERE]

例如:https://www.googleapis.com/drive/v3/changes/watch?pageToken=101

使用GET https://www.googleapis.com/drive/v3/changes/startPageToken获取列出的起始pageToken并观察将来的更改可能会很有趣.请参见此处

It might be interesting to use GET https://www.googleapis.com/drive/v3/changes/startPageToken to gets the starting pageToken for listing and watch future changes. See here
