解决问题!!


所以我一直关注这个迷你指南here

我已插入以下代码以方便访问。但是当我运行代码时(在输入谷歌的正确细节之后),我最后会收到错误。

Logging into Google...
Logged into Google
Searching for Worksheet 'S'...

JSON Parse Error: SyntaxError: Unexpected end of input

知道我做错了什么吗?我需要做些改变吗?同样为了学习,如果你也可以解释你是如何解决我的问题,而不仅仅是给我解决方案,以便我将来可以解决类似的问题。

这是在报告{_ 3}}的edit-google-spreadsheet模块时出错。尝试检索私有电子表格时会引发错误。您可以选择几个选项。

      
  • 将电子表格公开。
  •   
  • 尝试使用here。看起来仍有问题需要解决。
  •   
  •     使用工作表ID而不是工作表名称。这是一个更困难的过程:     
            
    1. 首先在google drive中打开电子表格
    2.       
    3.         在网址中找到电子表格ID。例:         
      https://docs.google.com/spreadsheets/d/SPREADSHEET_ID_HERE/edit?usp=drive_web
            
    4.       
    5.         通过转到此网址列出来源:         
      view-source:https://spreadsheets.google.com/feeds/worksheets/SPREADSHEET_ID_HERE/private/full
            
    6.       
    7.         从响应中找到条目(以下示例中的od6):       
    8.        
<entry>
    <id>https://spreadsheets.google.com/feeds/worksheets/SPREADSHEET_ID_HERE/private/full/od6</id>
    ...
    <title type='text'>Sheet1</title>
    ...
