GET / POST请求Google Drive API [英] GET/POST requests Google Drive API

问题描述

我目前学习Google Drive API并在Qt C ++中开发程序（使用OAuth2），所以我需要构建查询，但我找不到如何去做。

例如，如果我提出请求 - https：// www .googleapis.com / oauth2 / v1 / userinfo？access_token = MY_ACCESS_TOKEN ，一切正常 - 我收到回复。

问题是：如何使一个简单的Google Drive请求？

1）如何获取文件夹和文件的列表

2）如何创建文件夹/文件
等。

例如，在POST请求中
https：//www.googleapis .com / drive / v1 / files& title = pets& mimeType = application / vnd.google-apps.folder

我得到

error：{
errors：[{
domain：global，
reason：parseError，
message：Parse Error
}
]，
代码：400，
消息：解析错误
}
}

如何获取文件夹列表和文件，例如，等等，我不明白

欢迎任何意见/例子！

谢谢提前

解决方案

遗憾的是，Drive API不允许您列出文件夹或文件。检索文件的唯一方法是与云端硬盘网络用户界面集成或显示 Google Picker 给您的用户（仅限网络应用程序）。

一旦您拥有文件ID，您只需将授权的GET请求发送到 drive.files.get endpoint ：

  GET https://www.googleapis.com/drive/v1/files/id 
  

要插入文件（或文件夹），文件的元数据将成为包含在请求体中，而不是查询参数：

  POST https://www.googleapis.com/drive/v1/文件
 Authorization：Bearer {ACCESS_TOKEN} 
 Content-Type：application / json 
 ... 
 {
title：pets，
 parentsCollection：[{id：0ADK06pfg}] 
mimeType：application / vnd.google -apps.folder
} 
  

在上面的例子中， mimeType 指定被插入的资源是一个文件夹。插入文件时将 mimeType 更改为您的应用程序MIME类型。

I learning currently Google Drive API and developing program in Qt C + + (using OAuth2), so I need to build queries, but I'm not found how to do it.

For example, if I make a request - https://www.googleapis.com/oauth2/v1/userinfo?access_token=MY_ACCESS_TOKEN, everything is working OK - I get the reply.

Question is: how to make a SIMILAR request for the Google Drive?

1) how can I get a list of folders and files

2) how can I create a folder / file etc.

For example, in a POST request "https://www.googleapis.com/drive/v1/files&title=pets&mimeType=application/vnd.google-apps.folder"

I get

"error": { "errors": [{ "domain": "global", "reason": "parseError", "message": "Parse Error" } ], "code": 400, "message": "Parse Error" } }

how to get a list of folders and files, for example, etc., I do not understand

Any opinions/examples are welcome!

thanks in advance

解决方案

Unfortunately, the Drive API doesn't let you list folders or files. The only way to retrieve a file is by integrating with the Drive web UI or showing a Google Picker to your user (web app only).

Once you have a File ID, you can simply send an authorized GET request to the drive.files.get endpoint:

GET https://www.googleapis.com/drive/v1/files/id

To insert a file (or a folder), the File's metadata is to be included in the request body, not as query parameter:

POST https://www.googleapis.com/drive/v1/files
Authorization: Bearer {ACCESS_TOKEN}
Content-Type: application/json
...
{
  "title": "pets",
  "parentsCollection": [{"id":"0ADK06pfg"}]
  "mimeType": "application/vnd.google-apps.folder"
}

In the example above, the mimeType specifies that the resource being inserted is a folder. Change the mimeType to your application MIME type when inserting a file.
