无法使用Google文档列表+ oAuth REST协议下载文件

Question

使用以下工具oAuth Playground，并遵循文档Google Documents List API version 3.0。这就是我所做的。

1. 我获得了以下3个范围的访问令牌。 https://docs.google.com/feeds/ https://docs.googleusercontent.com/ https://spreadsheets.google.com/feeds/。请参阅以下附件。

   

2. 获取访问令牌和刷新令牌后，我开始进行查询，获取特定文档的下载URL。我提出了以下GET请求https://docs.google.com/feeds/default/private/full/?v=3。回应或多或少像

    ...

1. 然后我输入下载网址https://doc-0s-84-docs.googleusercontent.com/docs/securesc/4t...626&e=download&gd=true。结果看起来像这样。



但是，我得到以下回应。

我得到相同的结果，即使我在网址背面附加了?v=3，使其看起来像https://doc-0s-84-docs.googleusercontent.com/docs/securesc/4t...626&e=download&gd=true?v=3

我为什么会收到这样的错误？

Answer 1

您使用的网址是URL编码的。只需在网址中将&e=download&gd=true更改为&e=download&gd=true即可。
