ruby-on-rails – 在尝试使用AngularJS将数据发布到RAils服务器时获取ActionController :: RoutingError(没有路由匹配[OPTIONS]“ users”

概述尝试从我的AngularJS端向Rails服务器发送数据时遇到问题. 服务器错误： ActionController::RoutingError (No route matches [OPTIONS] "/users"): actionpack (4.1.9) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call' a 尝试从我的AngularJs端向Rails服务器发送数据时遇到问题.

所以这将是我的Rails服务器控制器和路由文件.

用户控制器

class UsersController < ApplicationController  def index    respond_to do |format|      format.Json {render Json: { name: 'Jonhy'},callback: params[:callback]}    end  end  def new  end  def create_user    puts user_params    @user = User.new(user_params)    if @user.save      render Json: { error: false },layout: false    else      render Json: { error: true },layout: false    end  end  def show  end  def user_params    params.require(:user).permit(:email,:password,:password_confirmation)  endend

应用控制器

class ApplicationController < ActionController::Base  # Prevent CSRF attacks by raising an exception.  # For APIs,you may want to use :null_session instead.  protect_from_forgery with: :exception  before_filter :allow_AJAX_request_from_other_domains def allow_AJAX_request_from_other_domains   headers['Access-Control-Allow-Origin'] = 'http://localhost:8001'   headers['Access-Control-Request-Method'] = '*'   headers['Access-Control-Allow-headers'] = '*' endend

击溃

Rails.application.routes.draw do  root 'home#index'  resources :users do    collection { post :create_user,via: :options  }  endend

这是我的AngularJs,我在那里制作POST AJAX.

var App = angular.module('OutOfBox',['ng.deviceDetector','ngRoute','ngResource']);App.factory('Users',function($resource){    var users =     $resource('http://127.0.0.1\:8001/:user',{user:'users'},{        query: {method:'GET',isArray: true},save: {method:'POST',isArray: false}     });     return users;  });App.controller('MainCtrl',['$scope','$http','Users',function($scope,$http,Users) {    $scope.user = [];    $scope.responsive = [];    $scope.submit = function() {      if ($scope.users.email && $scope.users.password && $scope.users.password_confirmation) {        $scope.user.push(this.users);         Users.save({user: $scope.user},function(){         console.log(':)')        },function(error){          console.log(error)        });        $scope.users = '';      }    };}]);App.config(['$routeProvIDer','$locationProvIDer','$httpProvIDer',function($routeProvIDer,$locationProvIDer,$httpProvIDer) {    $routeProvIDer.      when('/home',{        templateUrl: 'vIEws/main.HTML',controller: 'MainCtrl'      }).      otherwise({        redirectTo: '/home'      });              // use the HTML5 History API        $locationProvIDer.HTML5Mode(true);        $httpProvIDer.defaults.useXDomain = true;delete $httpProvIDer.defaults.headers.common["X-Requested-With"];  }]);

所以我尝试了很多解决方案,但没有人修复我的.

解决方法 Rails无法处理[OPTIONS]请求

您必须安装rack-cors才能处理CORS.

这是你的问题来自哪里：

resources :users do    collection { post :create_user,via: :options  }    # via: :options ?  end
