        function printFile(fileId) {
            var theID = '0B2XoJnBPsMpeaTdrX2pibl9GOE0';
            var request = gapi.client.request({
                'path': '/drive/v2/files/' + theID,
                'method': 'GET',
            });
            request.execute(function (resp) {
                console.log('Title: ' + resp.title);
                console.log('Description: ' + resp.description);
                console.log('MIME type: ' + resp.mimeType);
                console.log('WebContent: ' + resp.webContentLink);
            });

推荐答案

使用google drive api。

Google Drive Api [< a href =http://www.daimto.com/google-drive-api-c-upload/target =_ blanktitle =新窗口> ^ ]



有一个很好的如何在网站和一个示例项目上实现教程。

只需按照这种方式实现它就可以了。

Use the google drive api for that.
Google Drive Api[^]

There is a good how to implement tutorial on the site and a sample project.
Just implement it that way and you will be good to go.
