如何使用目录 API 或 Cloud Identity API 获取 Google 群组内容

Question

Can anyone please suggest to me how to get the content of google groups by using 2 different API

1. Cloud identity API
2. google directory API

We need to get the google group content.

Answer 1

Well, both APIs can interact with Google groups, however, there are subtle differences between them than you can check here .

I would strongly recommend using the Directory API as it has better documentation and as the Cloud Identity API requires either a Cloud Identity Free or a Cloud Identity Premium account. But of course, either of them can be used.

Directory API

For Directory API I would recommend taking a look at the Quickstart , as everything regarding the API's setup in your favorite programming language is explained there.

The documentation on how to deal with groups is here .

Of course, Apps Script is the most straightforward tool to fetch that information, as it can be achieved in a few lines (and adding the AdminDirectory service):

function myFunction() {

  var groupList = AdminDirectory.Groups.list({customer:"my_customer"})["groups"];
  
  for (var i = 0; i < groupList.length; i++){ 
    console.log(groupList[i].name+": " + groupList[i].description);
  }
}

Cloud Identity API

Regarding Cloud Identity API , you will need to follow this setup .

Then, the documentation regarding groups can be found here .

As an example, here is how it could be done in Apps Script :

function myFunction() {
  var customerId = AdminDirectory.Users.get(Session.getEffectiveUser().getEmail()).customerId;

  var url = "https://cloudidentity.googleapis.com/v1beta1/groups?parent=customers/"+customerId;
  var params = {
    method: "get",
    headers: {"Authorization": "Bearer " + ScriptApp.getOAuthToken()},
  };
  
    var groups = JSON.parse(UrlFetchApp.fetch(url,params).getContentText()).groups;
    
    for(var i = 0; i< groups.length;i++){
      console.log(groups[i].displayName); 
    }
}

For that you would also need to append the following line in the appscript.json manifest file. You can open it by going to Project Settings -> Show "appsscript.json" manifest file in editor :

"oauthScopes": ["https://www.googleapis.com/auth/script.external_request",
 "https://www.googleapis.com/auth/cloud-identity.groups"]
