about pagination gmail api with php

Question

I listed the messages in My App successfully. Now I need to paginate the messages (about 8 in every page). I followed the doc of google but it only gives a pageToken but how to make it work?

Answer 1

If you list messages , and there still are more results to fetch, the response will contain a nextPageToken .

Request

userId = me
maxResults = 8

GET https://www.googleapis.com/gmail/v1/users/me/messages?maxResults=8&access_token={YOUR_API_KEY}

Response

{
 "messages": [
  {
   "id": "151596a5055b9412",
   "threadId": "151596a5055b9412"
  },
  {
   "id": "1515915d0fcfd685",
   "threadId": "1515915d0fcfd685"
  },
  {
   "id": "15158e6826ed7587",
   "threadId": "15158e6826ed7587"
  },
  {
   "id": "15158e0e37572671",
   "threadId": "15158e0e37572671"
  },
  {
   "id": "151586443b5b309a",
   "threadId": "151586443b5b309a"
  },
  {
   "id": "15157c4b11732c5c",
   "threadId": "1510f004b81a9de2"
  },
  {
   "id": "151576512d37c9ec",
   "threadId": "1515765122918d37"
  },
  {
   "id": "1515765122918d37",
   "threadId": "1515765122918d37"
  }
 ],
 "nextPageToken": "01770178536732383613", // Here it is!
 "resultSizeEstimate": 26
}

Just include this value as the pageToken in the next request.

Request

userId = me
maxResults = 8
pageToken = 01770178536732383613

GET https://www.googleapis.com/gmail/v1/users/me/messages?maxResults=8&pageToken=01770178536732383613&access_token={YOUR_API_KEY}

Response

{
 "messages": [
  {
   "id": "1515762549119366",
   "threadId": "1513f096ab90fdab"
  },
  {
   "id": "15157616d03a66a1",
   "threadId": "1513f096ab90fdab"
  },
  {
   "id": "151575f958ac69e8",
   "threadId": "1513338849950602"
  },
  {
   "id": "1515756737710843",
   "threadId": "1515756737710843"
  },
  {
   "id": "1515756735412b45",
   "threadId": "1515756735412b45"
  },
  {
   "id": "1515756710eed602",
   "threadId": "1515756710eed602"
  },
  {
   "id": "15157567089a24b0",
   "threadId": "15157567089a24b0"
  },
  {
   "id": "151574a87fefe71d",
   "threadId": "151336e890f46a2c"
  }
 ],
 "nextPageToken": "13534757816909071635",
 "resultSizeEstimate": 27
}

When there is no nextPageToken in the response you have fetched every result there is.

我找到的解决方案是将所有令牌存储在前面的数组中，它使您能够在页面之间前进和后退，作为页面数组的索引，如果它没有给您带来 nextPageToken 它是因为它是最后一个，那么您将当前令牌（您所在页面的）作为参数传递，它会为您带来该页面的电子邮件列表。
