如何使用 Drive API 设置文件的元数据？

Question

I'm looking for a solution to uploading the files with some specific metadata! I tried to set canDownload to false, but there is no reflection in the result! And I want to set the file to Everybody can access. Here is my code:

const jwToken = new google.auth.JWT(
            token.client_email,
            null,
            token.private_key,
            ["https://www.googleapis.com/auth/drive"],
            null
        );

        jwToken.authorize((err : any) => {
            if (err) {
                console.log(err);
            } else {
                console.log("Authentication Success!");
            }
        });

 const metaData = {
            'name': filename,
            "shared": true,
            "capabilities" : {
                    "canDownload": false
            },
            parents: [folderId]
        };

        const media = {
            mimeType: 'Application/Pdf',
            body: fileSystem.createReadStream(pathSystem.join(path))
        };

        drive.files.create({
            auth     : jwToken,
            resource : metaData,
            media    : media,
            fields   : 'id'
        }, (err : any, file : any) => {
            if (err) {
                console.log("coming!!");

                throw err;
            } else {
                console.log("File Upload Successfully!");
            }
        });

Answer 1

• You don't want to make users download the created file.
• You want to share with anyone as reader.
• You want to achieve this using googleapis with Node.js.
  • Your script is typescript. And you build it and run it with Node.js.
• You have already been able to create a file to Google Drive using Drive API.

If my understanding is correct, how about this answer? Please think of this as just one of several possible answers.

Modification points:

About capabilities :

Unfortunately, the property of capabilities.canDownload is not writable . By this, as a method, how about using copyRequiresWriterPermission ? Using this, the file is set as "Disable options to download, print and copy for commenters and viewers".

About shared :

The property of shared is also not writable . So when you want to share with anyone as reader, please use the method of Permissions: create in Drive API.

Modified script:

When your script is modified, please modify as follows.

From:

const metaData = {
           'name': filename,
           "shared": true,
           "capabilities" : {
                   "canDownload": false
           },
           parents: [folderId]
       };

       const media = {
           mimeType: 'Application/Pdf',
           body: fileSystem.createReadStream(pathSystem.join(path))
       };

       drive.files.create({
           auth     : jwToken,
           resource : metaData,
           media    : media,
           fields   : 'id'
       }, (err : any, file : any) => {
           if (err) {
               console.log("coming!!");

               throw err;
           } else {
               console.log("File Upload Successfully!");
           }
       });

To:

const metaData = {
  name: filename,
  parents: [folderId],
  copyRequiresWriterPermission: true
};

const media = {
  mimeType: "application/pdf",
  body: fileSystem.createReadStream(pathSystem.join(path))
};
drive.files.create(
  {
    auth: jwToken,
    resource: metaData,
    media: media,
    fields: "id"
  },
  (err: any, file: any) => {
    if (err) {
      console.log(err);
      return;
    }
    const fileId = file.data.id;
    console.log(fileId);
    const body = {
      auth: jwToken,
      fileId: fileId,
      requestBody: {
        role: "reader",
        type: "anyone"
      }
    };
    drive.permissions.create(body, (err: any, res: any) => {
      if (err) {
        console.error(err);
        return;
      }
      console.log(res.data);
    });
  }
);

• In order to not make users download the uploaded file, copyRequiresWriterPermission: true is added to the request body of Files: create.
• In order to share with anyone, {role: "reader", type: "anyone"} is used to the request body of Permissions: create.

Note:

• In your script, the service account is used. So if you want to see the uploaded file in your Google Drive, please share it with your Google account. By this, you can see it using your browser. Please be careful this.

• Files: create
