Fail to download file using Google Document List + oAuth REST protocol

Question

By using the following tool oAuth Playground, and following the documentation Google Documents List API version 3.0. Here is what I had done.

1. I get access token for the following 3 scopes. https://docs.google.com/feeds/ https://docs.googleusercontent.com/ https://spreadsheets.google.com/feeds/. Please refer to the following attachment.

   

2. After getting access token and refresh token, I begin to make query, to get the download URL for a particular document. I made the following GET request https://docs.google.com/feeds/default/private/full/?v=3. The respond is something more or less like

---

<entry ...
    ...
    <content type='application/zip' src='https://doc-0s-84-docs.googleusercontent.com/docs/securesc/4t...626&amp;e=download&amp;gd=true'/>
    ...
</entry>

3. I then key in the download URL https://doc-0s-84-docs.googleusercontent.com/docs/securesc/4t...626&e=download&gd=true. The result looks like this.

However, I am getting the following respond.

I get the same result, even though I append ?v=3 at the back of URL which makes it looks like https://doc-0s-84-docs.googleusercontent.com/docs/securesc/4t...626&e=download&gd=true?v=3

Any idea on why I am getting such error?

Answer 1

The URL you are using is URL encoded. Simply change &e=download&gd=true to &e=download&gd=true in the URL.
