Google Drive文件读取元数据 [英] Google Drive files meta data read

问题描述

我试图使用Google Picker在我的webapp上显示谷歌驱动器选定的图像。为了获得图像的web内容，我需要阅读元数据。然而，我收到了一个类似这样的错误。

I am trying to get the google drive selected images displayed on my webapp using Google Picker. In order to get the webcontent of image, I need to read the metadata. However I am getting an error that is something like this

Uncaught TypeError: Cannot read property 'files' of undefined localhost:169
printFile localhost:169
pickerCallback localhost:156
K.Ld default.I.js:103
_.zc cb=gapi.loaded_0:57
_.Ib

这里是我使用的代码

    function printFile(fileId) {
    var request = gapi.client.drive.files.get({
        'fileId': fileId

        });
      request.execute(function(resp) {
        console.log('Title: ' + resp.title);
        console.log('Description: ' + resp.description);
        console.log('MIME type: ' + resp.mimeType);
      });
     }

获取图像元数据后，我将使用Webcontent在webapp上显示图像但它只是没有获取元数据。请告诉我如何解决这个错误。

Once I get the metadata of images I will use Webcontent for image display on webapp but its just not getting the metadata. Please tell me how to fix this error.

推荐答案

使用另一段代码工作：

Got it working using another piece of code which is:

    function printFile(fileId) {
    var theID = fileId;
    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);
             });
    }
