让Google文件选取器与drive.file作用域一起工作 [英] Getting Google file picker to work with drive.file scope

问题描述

我试图使用Google文件选择器来选择文档，然后更新其权限。我不需要访问所有选中的云端硬盘文件。 然而，当使用 https：/ /www.googleapis.com/auth/drive.file 作用域，当我尝试更改文档的权限时，出现404错误。如果我使用 https://www.googleapis.com/auth/drive 范围，但是这给了我更多的访问权限。

有没有什么办法让文件选取器与更有限的 https://www.googleapis.com/auth/drive.file 范围？

这是我的文件选取器代码：

 <！ - 标准的Google Loader脚本。 - > 
< script src =http://www.google.com/jsapi>< / script> 
< script type =text / javascript> 
 
 
 //使用Google Loader脚本加载google.picker脚本。 
 //google.setOnLoadCallback (createPicker）; 
 google.load（'picker'，'1'）; 
 
 //创建并呈现Picker对象
函数createPicker（）{
 var view = new google.picker.DocsView（google.picker.ViewId.DOCS）; 
 view.setMode（google.picker.DocsViewMode.LIST）; 
 //view.setMimeTypes(\"image/png,image/jpeg,image/jpg）; 
 var picker = new google.picker.PickerBuilder（）
 //.enableFeature(google.picker.Feature.NAV_HIDDEN）
 //.enableFeature（googleoglecrick.Feature.MULTISELECT_ENABLED）
 .setAppId（<％= ENV ['GOOGLE_ID']％>）
 .setOAuthToken（<％= current_user.token％>）//可选：使用的授权令牌在当前的Drive API会话中。 
 .addView（view）
 .addView（new google.picker.DocsUploadView（））
 .setCallback（pickerCallback）
 .build（）; 
 picker.setVisible（true）; 
 
} 
 
 
 //回调执行。 
函数pickerCallback（data）{
 var url ='nothing'; 
 if（data [google.picker.Response.ACTION] == google.picker.Action.PICKED）{
 var doc = data [google.picker.Response.DOCUMENTS] [0]; 
 url = doc [google.picker.Document.URL]; 
 title = doc.name; 
 id = doc.id; 
 type = doc.type; 
 embed = doc [google.picker.Document.EMBEDDABLE_URL]; 
} 
  

解决方案

回答我自己的问题，谢谢来自Google Drive Developer上关于Google Plus的讨论中的帮助：

这确实有效。我在我的选择器实现中使用了错误的App_ID - 我只需要在客户端ID的开头使用数字字符串。另一个问题是，它不能在本地主机上运行，​​只能在生产环境中运行。

I'm trying to use the Google file picker to select a document and then update its permissions. I don't need access to all Drive files, just those selected.

However, when using the https://www.googleapis.com/auth/drive.file scope, I'm getting a 404 error when I try to change the permissions of the doc. I don't get this error if I use the https://www.googleapis.com/auth/drive scope, but this gives me more access than I need.

Is there any way to get the file picker working with the more limited https://www.googleapis.com/auth/drive.file scope?

Here's my file picker code:

 <!-- The standard Google Loader script. -->
    <script src="http://www.google.com/jsapi"></script>
    <script type="text/javascript">


    // Use the Google Loader script to load the google.picker script.
    //google.setOnLoadCallback(createPicker);
    google.load('picker', '1');

    // Create and render a Picker object 
    function createPicker() {
         var view = new google.picker.DocsView(google.picker.ViewId.DOCS);
         view.setMode(google.picker.DocsViewMode.LIST);
          //view.setMimeTypes("image/png,image/jpeg,image/jpg");    
          var picker = new google.picker.PickerBuilder()
          //.enableFeature(google.picker.Feature.NAV_HIDDEN)
          //.enableFeature(google.picker.Feature.MULTISELECT_ENABLED)
          .setAppId("<%= ENV['GOOGLE_ID']%>")
          .setOAuthToken("<%= current_user.token %>") //Optional: The auth token used in the current Drive API session.
          .addView(view)
          .addView(new google.picker.DocsUploadView())
          .setCallback(pickerCallback)
          .build();
       picker.setVisible(true);

    }


    // callback implementation.
    function pickerCallback(data) {
      var url = 'nothing';
      if (data[google.picker.Response.ACTION] == google.picker.Action.PICKED) {
        var doc = data[google.picker.Response.DOCUMENTS][0];
        url = doc[google.picker.Document.URL];
        title = doc.name;
        id = doc.id;
        type = doc.type;
        embed = doc[google.picker.Document.EMBEDDABLE_URL ];
      }

解决方案

Answering my own question thanks to help from folks on the Google Drive Developer discussion on Google Plus:

This does work. I was using the wrong App_ID in my picker implementation - I needed to use only the numeric string at the beginning of the client ID. The other problem, it doesn't work on localhost, only in production.
