How to make the file shareable using google drive api

Question

I am trying to get the file using google drive api, by default the file is not shareable i want to make it shareable.

Here is my code:-

    <script type="text/javascript" src="https://apis.google.com/js/api.js"></script>
<script src="https://apis.google.com/js/client.js"></script>
        // The Browser API key obtained from the Google Developers Console.
            // Replace with your own Browser API key, or your own key.
            var developerKey = 'XXXXXXXXXX_ff_NX66eb-XXXXXXXXXXX';

            // The Client ID obtained from the Google Developers Console. Replace with your own Client ID.
            var clientId = "XXXXXXXXXX-hs4ujaro5sc3d0g8qndtcq2tl279cfm1.apps.googleusercontent.com"

            // Replace with your own App ID. (Its the first number in your Client ID)
            var appId = "XXXXXXXXXX";
            // Scope to use to access user's Drive items.
            var scope = ['https://www.googleapis.com/auth/drive'];

            var pickerApiLoaded = false;
            var oauthToken;

                  $scope.addGoogleDriveFile = function() {
                    gapi.load('auth', {'callback': onAuthApiLoad});
                     gapi.load('picker', {'callback': onPickerApiLoad}); 
                    gapi.client.setApiKey(developerKey);     
                      }

        function onAuthApiLoad() {
                         window.gapi.auth.authorize(
                             {
                               'client_id': clientId,
                               'scope': scope,
                               'immediate': false
                             },
                             handleAuthResult);
                       }

                        function onPickerApiLoad() {
                          pickerApiLoaded = true;
                          createPicker();
                        }

                        function handleAuthResult(authResult) {
                          if (authResult && !authResult.error) {
                            oauthToken = authResult.access_token;
                            createPicker();
                          }
                        }

                        // Create and render a Picker object for searching images.
                        function createPicker() {
                          if (pickerApiLoaded && oauthToken) {
                            var view = new google.picker.View(google.picker.ViewId.DOCS);
                            var picker = new google.picker.PickerBuilder()
                                .enableFeature(google.picker.Feature.NAV_HIDDEN)
                                .setAppId(appId)
                                .setOAuthToken(oauthToken)
                                .addView(view)
                                .addView(new google.picker.DocsUploadView())
                                .setDeveloperKey(developerKey)
                                .setCallback(pickerCallback)
                                .build();
                             picker.setVisible(true);
                          }
                        }

                    // A simple callback implementation.
                    function pickerCallback(data) {
                      if (data.action == google.picker.Action.PICKED) {
                          console.log(data);
                       gapi.client.load('drive', 'v2').then(function() {
                            var request = gapi.client.drive.files.get({
                            'fileId': data.docs[0].id
                          });   
                           request.execute(function(resp) {
                             console.log(resp);
                          }); 
               });

                      }
                    }

Here i want to change "shared": true Instead of "shared": false

How can i change its permission?

Any Idea?

Thanks

Answer 1

@arun you may want to read more about Permission resource in Drive API. For "shared" to be true, each file permission needs to specifies a role, type, and email address or domain. As an owner of the file (Docs, Sheets, etc.), you will need to provide the appropriate permission to be set to.

Here is an example, using the Permissions.create (I recommend using Drive API v3)

POST https://www.googleapis.com/drive/v3/files/{fileId}/permissions?key={YOUR_API_KEY}

{
 "role": "reader",
 "type": "user",
 "emailAddress": "[email protected]"
}

Response from the Drive Files.get:

GET https://www.googleapis.com/drive/v3/files/{fileId}?fields=appProperties%2CfileExtension%2Ckind%2CmimeType%2Cshared&key={YOUR_API_KEY}


{
 "kind": "drive#file",
 "mimeType": "application/vnd.google-apps.document",
 "shared": true
}

However, if you are unable to switch to the Drive v3, you can still use the Permission.insert from Drive v2 to do the job. Hope this helpful and good luck!
