Question

使用RoR api后端和React前端构建应用程序。挂载App.js组件时，假设要调用后端，提取内容以填充前端。由于某种原因，尽管定义了route和http方法，但仍存在路由错误

App.js> ComponentDidMount（）方法

  async componentDidMount(){
    await getEvents(this.props.auth)
    .then((res) => {
      return res.json()})
    .then((json) => this.setState({
        events: [...json['events']]
    }))
    .catch((err) => {
      alert('There was an error retrieving events. ERROR: ' + err)
    })
  }

getEvents（）只是一个将Fetch api POST请求返回到我的api URL的函数。

Route.rb文件

Rails.application.routes.draw do
  devise_for :user, only: []
  namespace :v1, defaults: { format: :json } do
    resource :login, only: [:create], controller: :sessions
    resource :sign_up, only: [:create], controller: :users
    resource :event, only: [:create, :update, :destroy], controller: :events
    post '/event/event_like' => 'events#userLikes?'
    post '/events' => 'events#index'
    post '/event/like' => 'events#like'
    post '/event/group' => 'events#getGroup'
    delete '/event/unlike' => 'events#unlike'
  end
end

我不断收到的错误

已定义路由，但呼叫失败。有什么想法吗？

尽管已定义路线，但Rails路线错误
