我已經在我的Rails 4應用程序中設置了Google授權,它按預期工作。現在我想要使用Gmail API檢索授權的用戶電子郵件,但我在瀏覽器中收到#<Net::HTTPUnauthorized:0x0055ed1f7f8d68>錯誤,作爲對我的GET請求的響應。Net :: HTTPUnauthorized當試圖從RAILS訪問Gmail API 4

在開發控制檯中,我啓用了所有必需的API。

我的代碼:

初始化/ omniauth.rb

OmniAuth.config.logger = Rails.logger 

Rails.application.config.middleware.use OmniAuth::Builder do 
    provider :google_oauth2, Rails.application.secrets.client_id, Rails.application.secrets.client_secret, {scope: ['email', 
    'https://www.googleapis.com/auth/gmail.modify'], 
    access_type: 'offline', client_options: {ssl: {ca_file: Rails.root.join("cacert.pem").to_s}}} 
end 

User.rb

def self.from_omniauth(auth) 
    where(provider: auth.provider, uid: auth.uid).first_or_initialize.tap do |user| 
     user.provider = auth.provider 
     user.uid = auth.uid 
     user.name = auth.info.name 
     user.email = auth.info.email 
     user.oauth_token = auth.credentials.token 
     user.oauth_expires_at = Time.at(auth.credentials.expires_at) 
     user.save! 
    end 
    end 

在我的控制器:

def mail 
    require 'net/http' 
    access_token = current_user.oauth_token 
    e = current_user.email 
    u = "https://www.googleapis.com/gmail/v1/users/#{e}/messages? maxResults=50&key=#{access_token}" 
    url = URI.parse(u) 
    req = Net::HTTP::Post.new(url.request_uri) 
    http = Net::HTTP.new(url.host, url.port) 
    http.use_ssl = (url.scheme == "https") 
    response = http.request(req) 
    @resbody = response 
end 

在我看來

<%= @resbody %> 

安裝寶石:

gem "omniauth-google-oauth2", "~> 0.2.1" 
gem "google-api-client" 

當我試圖執行

curl https://www.googleapis.com/gmail/v1/users/my-email/messages&access_token=ya29.Ci .... A 
[1] 6687 

我收到這樣的消息:

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

問題:我不明白這一點。如果我獲得了Google帳戶的授權並將我的訪問令牌保存在數據庫中,並且稍後將其檢索爲與Gmail API一起使用,則它不起作用?

怎麼可能是我做的完全錯了?

在此先感謝。

登錄到Gmail帳戶,然後點擊右上角的圖片。點擊我的帳戶,然後點擊登錄和安全,然後向下滾動,直到看到「允許安全性較低的應用程序:」,然後開啓該功能。您將可以繼續使用Rails應用程序。 – sahil

@sahil謝謝,但仍然是同樣的問題.. – Edgars

與我的代碼中發現的問題:

req = Net::HTTP::Post.new(url.request_uri)變更爲req = Net::HTTP::Get.new(url.request_uri)

@resbody = response@resbody = response.body

現在我可以看到檢索郵件:)
