Rails：无法通过Slack进行身份验证

Question

非常感谢您提前帮助我。我正在开发一个应用程序，人们可以使用Slack对其进行身份验证，并且它会在自动生成内容的同时向其工作区发送通知。

但是发生oauth错误：

OAuth Error: Invalid client_id parameter

URL如下：

https://slack.com/oauth/authorize?client_id=XXXXXXXXXXX&scope=bot%2Cusers%3Aread.email%2Ccommands%2Cusers%3Aread&state=XXXXXXXXXXXXX&tracked=1

[尝试使用omniauth_slack gem时，我遇到了同样的问题。

app / views / home / index.html.erb

<%= link_to "Sign in with Slack", slack_activate_path %>

app / controllers / slack_controller.rb

class SlackController < ApplicationController
  def activate
    oauth_state = "XXXXXXXXXXXXX"
    uri = URI('https://slack.com/oauth/authorize')
    uri.query = {
      client_id: Rails.application.credentials[:slack][:client_id],
      scope: 'bot,users:read.email,commands,users:read',
      state: oauth_state,
    }.to_query

    redirect_to uri.to_s
  end

  def callback
  end
end

config / routes.rb

Rails.application.routes.draw do
  root 'home#index'

  match '/slack/activate', to: 'slack#activate', via: 'get'
  match '/slack/callback', to: 'slack#callback', via: 'get'

end

Answer 1

我在凭证上输错了client_id。这不需要.。
