使用 curl 列出谷歌驱动器文件

问题描述

我正在尝试使用 curl 获取 Google 云端硬盘上的文件列表，但 OAuth 2 对我来说是最好的.

以下是我尝试过的一些事情:

curl -H "授权: Bearer $token" https://www.googleapis.com/drive/v2/files

其中 $token 是我使用的 460 个字符的字符串:

https://www.google.com/accounts/ClientLogin

这个上传

记下client ID和client secret.

第 2 步:以驱动器为范围请求授权.

使用 client ID 和 https://docs.google.com/feeds 作为 scope，构造以下 curl 命令:

$ curl -d "client_id=413437979384-05efiod756k5hp2eji5tsn2lmlg0qslc.apps.googleusercontent.com&scope=https://docs.google.com/feeds" https://accounts.google.com/o/oauth2/设备/代码{"device_code" : "KRYU-NTVW4/qi6ysOpK2AtsmtZz4MB9LAthlYGGgAepxpBnGQLvhqo","user_code" : "KRYU-NTVW","verification_url" : "https://www.google.com/device",expires_in":1800，间隔":5}

复制user_code.

第 3 步:授权请求.

访问验证网址

第四步:获取access_token.

将auth请求得到的device_code添加到client ID和client secret中，构造如下curl命令:

$ curl -d "client_id=413437979384-05efiod756k5hp2eji5tsn2lmlg0qslc.apps.googleusercontent.com&client_secret=0zWNribRJ4PcYWH-rDkCpCcm&grant_type=http://oauth.net/grant_type/device/1.0&code=KRYU-NTVW4/qi6ysOpK2AtsmtZz4MB9LAthlYGGgAepxpBnGQLvhqo" https://www.googleapis.com/oauth2/v4/token{access_token":ya29.kgKW4Z4IDqK7lCjUQw-u5VT2uAx19MtgdoKeAC9ikKYGwKh7Nh46pY8nQsANQ5lRwA"，"token_type": "承载者",expires_in":3600，"refresh_token": "1/qinFVaMPYvhWtUtmjb1qCpnQt48XyvQhB_ILZJ4H1Uw"}

我们现在有了所需的 access_token，保存它并将其用于所有驱动器 REST API 请求.

第 5 步:驱动 API 请求.

$ curl -H 'GData-Version: 3.0' -H '授权:承载 ya29.kgKW4Z4IDqK7lCjUQw-u5VT2uAx19MtgdoKeAC9ikKYGwKh7Nh46pY8nQsANQ5lRwA' https://www.googleapis.com/drive/v2/files{种类":驱动器#fileList"，...

I'm trying to get the list of files on Google Drive with curl, but OAuth 2 is getting the best of me.

Here are some of the things I tried:

curl -H "Authorization: Bearer $token" https://www.googleapis.com/drive/v2/files

Where $token is a 460 character string I got using:

https://www.google.com/accounts/ClientLogin

and this upload script (which works great). This is the error I received:

 {
  "error": {
   "errors": [
    {
      "domain": "global",
      "reason": "authError",
      "message": "Invalid Credentials",
      "locationType": "header",
      "location": "Authorization"
    }
   ],
   "code": 401,
   "message": "Invalid Credentials"
  }
 }

Also tried:

curl https://www.googleapis.com/drive/v2/files?key=apiKey

Error:

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "required",
    "message": "Login Required",
    "locationType": "header",
    "location": "Authorization"
   }
  ],
  "code": 401,
  "message": "Login Required"
 }
}

And:

curl -H "Authorization: GoogleLogin auth=${token}" "https://www.googleapis.com/drive/v2/files"

Error:

{
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "dailyLimitExceededUnreg",
    "message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.",
    "extendedHelp": "https://code.google.com/apis/console"
   }
  ],
  "code": 403,
  "message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
 }
}

I had little success with both the JavaScript and PHP client libraries, both seem optimized for the situation where the user provides log/pass in order to authorize the app. What I need is a way to list the files from a single account, every time.

解决方案

I just spent like 30 minutes to figure this out myself for accessing contacts API and redid the steps for drive API and documented them for future reference. There are 5 steps and the first 4 are one time setup.

Step 1: Create new OAuth2 credentials

Note down the client ID and client secret.

Step 2: Request authorization with drive as scope.

Using the client ID and https://docs.google.com/feeds as scope, construct the below curl command:

$ curl -d "client_id=413437979384-05efiod756k5hp2eji5tsn2lmlg0qslc.apps.googleusercontent.com&scope=https://docs.google.com/feeds" https://accounts.google.com/o/oauth2/device/code
{
  "device_code" : "KRYU-NTVW4/qi6ysOpK2AtsmtZz4MB9LAthlYGGgAepxpBnGQLvhqo",
  "user_code" : "KRYU-NTVW",
  "verification_url" : "https://www.google.com/device",
  "expires_in" : 1800,
  "interval" : 5
}

Copy the user_code.

Step 3: Authorize the request.

Visit the verification URL https://www.google.com/device and enter the copied code.

Step 4: Obtain access_token.

Add the device_code obtained from the auth request to the client ID and client secret and construct the below curl command:

$ curl -d "client_id=413437979384-05efiod756k5hp2eji5tsn2lmlg0qslc.apps.googleusercontent.com&client_secret=0zWNribRJ4PcYWH-rDkCpCcm&grant_type=http://oauth.net/grant_type/device/1.0&code=KRYU-NTVW4/qi6ysOpK2AtsmtZz4MB9LAthlYGGgAepxpBnGQLvhqo" https://www.googleapis.com/oauth2/v4/token
{
 "access_token": "ya29.kgKW4Z4IDqK7lCjUQw-u5VT2uAx19MtgdoKeAC9ikKYGwKh7Nh46pY8nQsANQ5lRwA",
 "token_type": "Bearer",
 "expires_in": 3600,
 "refresh_token": "1/qinFVaMPYvhWtUtmjb1qCpnQt48XyvQhB_ILZJ4H1Uw"
}

We now have the required access_token, save it and use it with all the drive REST API requests.

Step 5: Drive API request.

$ curl -H 'GData-Version: 3.0' -H 'Authorization: Bearer ya29.kgKW4Z4IDqK7lCjUQw-u5VT2uAx19MtgdoKeAC9ikKYGwKh7Nh46pY8nQsANQ5lRwA' https://www.googleapis.com/drive/v2/files
{
 "kind": "drive#fileList",
