我是Ruby新手，我正在尝试实现一个带有客户端凭证流的oauth2。
我已经找到了“ouath 2”宝石，但这需要一个redirect_uri，而我没有。
Here is the gem。
这是我正在尝试实现的

secret_id = 'this-is-a-secret-id'
token_id = 'this-is-a-token-id'
scope = 'such-a-good-scope'
grant_type = 'client_credentials'
@client = nil

# Get access token

def GetAccessToken
    HttpRequest request = HttpRequest::Post("https://awesome-page.com/oauth/token")
    request.content = {
        { "client_id" => token_id },
        { "client_secret" => secret_id }
        { 'grant_type' => grant_type },
        { 'scope' => scope}
    }

    response = request.send
    json = response.content
    accessToken = JsonConvert.DeserializeObject<Token>(json)
    @client = Client.new(bearer: accessToken)
end

# Refresh token

def RefreshToken
    HttpRequest request = HttpRequest::Post("https://awesome-page.com/oauth/token")
    request.content = {
        { "client_id" => token_id },
        { "client_secret" => secret_id }
        { 'grant_type' => grant_type },
        { 'refresh_token' => scope}
    }

    response = request.send
    json = response.content
    accessToken = JsonConvert.DeserializeObject<Token>(json)
    @client = Client.new(bearer: accessToken)
end

# End then implementing the "getting the resources with the client" part and so on...

有什么办法吗我现在有点绝望了
任何帮助都将不胜感激！
