我按照guide在我的Ruby On Rails应用程序中实现了Yandex Oauth。几周我没有遇到任何问题,但最近(几天前)我遇到了问题。我无法获得访问令牌,刷新令牌等,因为我的请求因400错误代码而失败。
我收到了这条特定的消息:
{"error_description": "Code has expired", "error": "invalid_grant"}
来自指南:
此代码的生命周期为10分钟。当它到期时,代码必须 再次请求。
但它永远不会等待10分钟甚至10秒,因为只要我的应用程序获得授权代码,它就立即发出POST请求以更改访问令牌,刷新令牌和到期的授权代码。但是这个POST请求失败了,因为授权代码似乎已过期。
来自Yandex错误说明:
invalid_grant - 授权码无效或过期。
我的代码:
def yandex
require 'net/http'
require 'json' # => false
@user = User.from_omniauth(request.env["omniauth.auth"])
@client_id = Rails.application.secrets.client_id
@secret = Rails.application.secrets.password
@authorization_code = params[:code]
@user.update_attribute(:code, @authorization_code)
@user.update_attribute(:state, params[:state])
@post_body = "grant_type=authorization_code&code=#{@authorization_code}&client_id=#{@client_id}&client_secret=#{@secret}"
@url = "https://oauth.yandex.ru/token"
url = URI.parse(@url)
req = Net::HTTP::Post.new(url.request_uri)
req['host'] ="oauth.yandex.ru"
req['Content-Length'] = @post_body.length
req['Content-Type'] = 'application/x-www-form-urlencoded'
req.body = @post_body
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = (url.scheme == "https")
@response_mess = http.request(req)
refreshhash = JSON.parse(@response_mess.body)
access_token = refreshhash['access_token']
refresh_token = refreshhash['refresh_token']
access_token_expires_at = DateTime.now + refreshhash["expires_in"].to_i.seconds
if access_token.present? && refresh_token.present? && access_token_expires_at.present?
@user.update_attribute(:access_token, access_token)
@user.update_attribute(:refresh_token, refresh_token)
@user.update_attribute(:expires_in, access_token_expires_at)
sign_in(@user)
redirect_to admin_dashboard_index_path
end
end
我的日志:

我在CHROME POSTMAN中尝试了相同的POST请求,并收到与{"error_description": "Code has expired", "error": "invalid_grant"}
我已经google了一下,但没有任何类似的问题..似乎问题出在Yandex的末尾,但是如何绕过它呢?
任何帮助将不胜感激。

Yandex授权码是一次性使用的。您确定没有向" https://oauth.yandex.ru/token"两次?您可以尝试在Chrome Postman 之前提出此类请求评估您的代码。
