Ruby google_drive gem oAuth2 保存

Question

所以在更新之前，有一种简单的方法可以登录到 google drive 并操作您的 google 文档 - 使用 ruby​​。

在您能够使用此登录到您的谷歌驱动器之前。

require 'google_drive'
$session = GoogleDrive.login("email@gmail.com", "password")

但现在您收到警告消息：

WARNING: GoogleDrive.login is deprecated and will be removed in the next version. Use GoogleDrive.login_with_oauth instead.

所以我去了 git hub page 看看 google 希望我们如何使用高级语言的服务，并发现他们希望我们使用 oAuth2。像这样。

require 'google/api_client'
require 'google_drive'

client = Google::APIClient.new(
  :application_name => 'Example Ruby application',
  :application_version => '1.0.0'
)
auth = client.authorization
auth.client_id = "YOUR CLIENT ID"
auth.client_secret = "YOUR CLIENT SECRET"
auth.scope =
    "https://www.googleapis.com/auth/drive " +
    "https://spreadsheets.google.com/feeds/"
auth.redirect_uri = "urn:ietf:wg:oauth:2.0:oob"
print("1. Open this page:\n%s\n\n" % auth.authorization_uri)
print("2. Enter the authorization code shown in the page: ")
auth.code = $stdin.gets.chomp
auth.fetch_access_token!
access_token = auth.access_token

$session = GoogleDrive.login_with_oauth(access_token)

这很好，但我无法保存 auth 变量。 我想在脚本中对此进行硬编码，这样我就不必继续去谷歌获取新的 access_token。

所以我尝试获取 access_token 并将其添加到脚本中。

require 'google/api_client'
require 'google_drive'

client = Google::APIClient.new
access_token = "TokenFromGoogleHardCoded"

$session = GoogleDrive.login_with_oauth(access_token)

# $session doesn't connect

我不确定我是否在正确的庄园中解决了这个问题。我想保存完整的 auth 变量并将其硬编码到我的脚本中。

Answer 1

我发现了这个烂摊子。

auth.scope =
    "https://www.googleapis.com/auth/drive " +
    "https://spreadsheets.google.com/feeds/"

auth.scope 缺少 URL。 REFERENCE来自github

auth.scope =
    "https://docs.google.com/feeds/" +
    "https://www.googleapis.com/auth/drive " +
    "https://spreadsheets.google.com/feeds/"

您可以重复使用您的 access_token，但首先您需要获取它。警告：auth.access_token 只能使用一个小时。如果您需要另一个，您需要调用 auth.refresh！这将向您发出另一个 access_token。

require 'google/api_client'
require 'google_drive'

client = Google::APIClient.new(
  :application_name => 'Example Ruby application',
  :application_version => '1.0.0'
)
auth = client.authorization
auth.client_id = "YOUR CLIENT ID"
auth.client_secret = "YOUR CLIENT SECRET"
auth.scope =
    "https://www.googleapis.com/auth/drive " +
    "https://spreadsheets.google.com/feeds/"
auth.redirect_uri = "urn:ietf:wg:oauth:2.0:oob"
print("1. Open this page:\n%s\n\n" % auth.authorization_uri)
print("2. Enter the authorization code shown in the page: ")
auth.code = $stdin.gets.chomp
auth.fetch_access_token!
access_token = auth.access_token

system'clear'
print "Save your access token\n\n"
print access_token  
print "\nSave your refresh token\n\n"
print auth.refresh_token 

这段代码应该在你的控制台中打印出你的 access_token/refresh_token。现在您可以对您的应用程序进行硬编码了。

require "google/api_client"
require "google_driver"
client = Google::APIClient.new(
  :application_name => 'Example Ruby application',
  :application_version => '1.0.0'
)
auth = client.authorization
auth.client_id = "Your Client ID"
auth.client_secret = "Your client secret"

access_token = "token you saved from the terminal"

session = GoogleDrive.login_with_oauth(access_token)

for file in session.files
   p file.title
end

最终您的“access_token”将过期。此时您需要“刷新”它。你可以通过调用来查看你的access_token是否过期

auth.expires_at

您可以通过此示例获取新的访问令牌。

require 'google/api_client'
require 'google_drive'


$client_id = "YOUR CLIENT ID"
$client_secret = "YOUR CLIENT SECRET"
$refresh_token = "SAVED REFRESH TOKEN"

 client = Google::APIClient.new(:application_name => 'Example Ruby application', :application_version => '1.0.0')
    auth = client.authorization
    auth.client_id = $client_id
    auth.client_secret = $client_secret
    auth.scope = "https://docs.google.com/feeds/" + "https://www.googleapis.com/auth/drive " + "https://spreadsheets.google.com/feeds/"
    auth.redirect_uri = "urn:ietf:wg:oauth:2.0:oob"
    auth.refresh_token = $refresh_token

    #here's the magic sauce 
    auth.refresh! 

    #as you can see above auth.access_token wasn't passed a value
    # but if you call it now you'll see you have a new access_token

    auth.access_token
    => new token from server

您可能会发现使用服务帐户更容易，如下所述：

Answer 3

虽然 Duck1337 的回答会起作用，但您实际上并不需要使用 google_drive 1.0.* 调用 auth.refresh!。

您需要做的就是在第一次提供授权码时保存 refresh_token，然后始终在调用 auth.fetch_access_token! 之前传递该授权码！令牌会自动刷新。

下面是我用来登录的。我使用环境变量而不是代码常量，因此我可以将它们添加到 Heroku Config Vars 中，并且还可以将敏感数据排除在代码之外。

client = Google::APIClient.new
    auth = client.authorization
    auth.client_id = ENV['GOOGLE_CLIENT_ID']
    auth.client_secret = ENV['GOOGLE_CLIENT_SECRET']
    auth.scope = [
        "https://www.googleapis.com/auth/drive",
        "https://spreadsheets.google.com/feeds/"
    ]
    auth.redirect_uri = "urn:ietf:wg:oauth:2.0:oob"

    if ENV['GOOGLE_REFRESH_TOKEN'] == "0" # Always start with 0 in your .env file, e.g. GOOGLE_REFRESH_TOKEN = 0
      puts("1. Open this page:\n%s\n\n" % auth.authorization_uri)
      puts("2. Enter the authorization code shown in the page: ")
      auth.code = $stdin.gets.chomp
    end if

    auth.refresh_token = ENV['GOOGLE_REFRESH_TOKEN'] #this will be 0 the first time around, but that's OK
    auth.fetch_access_token!

    if ENV['GOOGLE_REFRESH_TOKEN'] == "0"   
      puts("3. Save this refresh token:\n%s\n\n" % auth.refresh_token) # you can now replace the 0 in your .env file with this token, so it'll be used permanently.  You can also add this to the Heroku Config Vars.
      ENV['GOOGLE_REFRESH_TOKEN'] = auth.refresh_token #we'll set it here, so it works without having to alter the .env file for this call
    end if

    GoogleDrive.login_with_oauth(auth.access_token)

使用 capybara 并导航到令牌页面。从页面源中获取它并保存到变量中。需要时插入变量。令牌字符串已过期，因此我每次需要访问电子表格时都会获取一个新字符串。
