如何从React客户端向rails后端发送POST请求？ （ActionController :: RoutingError（没有路由与[POST]匹配）

Question

我正在开发React前端/ Rails后端应用程序，并且正在开发用户的登录名。为此，我从客户端向后端执行POST请求。但是，我遇到了RoutingError，但是我无法弄清楚为什么在运行rake路由时我的路由看起来很好

我尝试使用fetch函数参数来解决该问题，但是什么也没做。

我的提取功能：

fetch("http://localhost:3000/users/create", {
      method: "POST",
      mode: "no-cors",
      cache: "no-cache",
      credentials: "same-origin",
      headers: {
          "Content-Type": "application/json"
      },
      body: JSON.stringify({
          email: this.state.email,
          password: this.state.password
      })
    })
    .then(response => response.json())
    .then(response => {
      console.log(response)
    })

我的路线：

Rails.application.routes.draw do

  resources :meals, only: [:index]

  resources :users, only: [:new, :create]

end

我的users_controller：

class UsersController < ApplicationController

    def new
        @user = User.new

    end

    def create
        @user = User.new(params)
        @user.save
        render json: @user, status: 201

    end

end

我希望通过发布请求进入localhost：3000 / users / create，但是却收到以下错误消息：
