angularjs – 向Rails API发送带有参数的角度请求

我无法将角度前端与Rails后端API完全集成。他们都运行在不同的服务器，所以我认为我有CORS的问题。

我的Angular应用程序正在运行一个控制器，该控制器正在调用具有查询(GET)和保存(POST)方法的资源的服务。查询(GET)工作正常，但是该帖子不工作。

当我没有发送任何参数时，我可以向服务器发送POST请求。喜欢这个：

控制器：

$scope.createBusiness = function() {

        console.log("Business.name=" + $scope.business.name);           
        $scope.business = Business.save(); 
    };

服务：

.factory('Business',function($resource){          
    var businesses =
     $resource('http://127.0.0.1\\:3000/:business',{business:'businesses'},{      
        query: {method:'GET',isArray: true},save: {method:'POST',isArray: false}
     });        
     return businesses;           
  }

);

但是，我想发布我的模型参数，所以当我尝试发送一些东西，然后我不再发送一个POST请求，而是一个OPTIONS请求。我收到一个错误。

当我发送没有参数的请求(POST请求)时，请查看我的请求数据：

我到达服务器，执行方法并得到响应！还行吧。

当我发送一个请求WITH参数(OPTIONS请求)时，请查看我的请求数据：

UPDATE

添加模型参数时，我忘记添加控制器：

$scope.createBusiness = function() {

        console.log("Business.name=" + $scope.business.name);           
        $scope.business = Business.save($scope.business); 
    };

我有几个意见，有几种形式，所以，我不想只发布一个表单，但是我有范围的业务对象模型(我填写了所有表单的数据)。

UPDATE

这是我的Rails Application_Controller(CORS配置)：

class ApplicationController < ActionController::Base


 # Prevent CSRF attacks by raising an exception.
  # For APIs,you may want to use :null_session instead.
  # OJOJOOJO: Rober: I have commented this line which is provided by default with rails and added all code below in order to 
  # add CSRF protection 
  #protect_from_forgery with: :exception

  protect_from_forgery

  before_filter :cors_preflight_check
  after_filter :cors_set_access_control_headers,:set_csrf_cookie_for_ng

# For all responses in this controller,return the CORS access control headers.

  def cors_set_access_control_headers
    headers['Access-Control-Allow-Origin'] = '*'
    headers['Access-Control-Allow-Methods'] = 'POST,OPTIONS'
    headers['Access-Control-Request-Method'] = '*'
    headers['Access-Control-Allow-Headers'] = 'Origin,Authorization'
    headers['Access-Control-Max-Age'] = "1728000"
  end

# If this is a preflight OPTIONS request,then short-circuit the
# request,return only the necessary headers and return an empty
# text/plain.

  def cors_preflight_check
    if request.method == :options
      headers['Access-Control-Allow-Origin'] = '*'
      headers['Access-Control-Allow-Methods'] = 'POST,OPTIONS'
      headers['Access-Control-Request-Method'] = '*'
      headers['Access-Control-Allow-Headers'] = 'Origin,Authorization'
      headers['Access-Control-Max-Age'] = '1728000'
      render :text => '',:content_type => 'text/plain'
    end
  end

  def set_csrf_cookie_for_ng
    cookies['XSRF-TOKEN'] = form_authenticity_token if protect_against_forgery?
  end

protected

  def verified_request?
    super || form_authenticity_token == request.headers['X_XSRF_TOKEN']
  end  
end

我终于做好了工作。

我会解释所有我的配置在Angular和Rails 4，因为我会喜欢阅读它。

角

> app.js：

angular.module('myApp',['myApp.filters','myApp.services','myApp.directives','myApp.controllers','myApp.i18n','demo']).
config(['$routeProvider','$httpProvider',function($routeProvider,$httpProvider) {

$httpProvider.defaults.useXDomain = true;
delete $httpProvider.defaults.headers.common["X-Requested-With"];

}]);

注意：当然，您不需要包含我所有的模块。

>在我看来：

<form novalidate="" name="createBusinessForm" ng-submit="setBusinessInformation()" class="css-form">            
        <label>* {{'BUSINESS_NAME' | translate}}</label>
        <input type="text" name="name" ng-model="business.name" class="input-xxlarge input-height-large" placeholder="{{'BUSINESS_NAME_PLACEHOLDER' | translate}}" required maxlength="80">
        <span ng-show="createBusinessForm.name.$dirty && createBusinessForm.name.$error.required" class="text-error">Mandatory field.</span>
        <label>* {{'ID' | translate}}</label>    
        <input type="text" ng-model="business.cif_nif" class="input-xlarge input-height-large" placeholder="{{'BUSINESS_ID_PLACEHOLDER' | translate}}" required maxlength="60">        
        <label>* {{'ADDRESS' | translate}}</label>

注意：您可以根据需要定义尽可能多的字段，并使用数据bingind将值分配给对象。

>在我的控制器：

$scope.createBusiness = function() {

        $scope.business.type = $scope.type; 
        $scope.business.plan = $scope.plan;     
        $scope.business = Business.save($scope.business);           
        $location.path('/user-dashboard');                              
    };

注意：发送请求中需要发送的所有属性。除了表单，您可以在发送到Rails API之前，将一些新属性分配给对象。我们将使用与资源对象的服务来发送POST请求。

>在我的服务：

.factory( ‘商务’，

function($resource){          
    var businesses =
     $resource('http://127.0.0.1\\:3000/:business',isArray: false}
     });        
     return businesses;           
  }

);

注意：我有一个GET请求，通过Rails API和POST一个从DB获取业务。

轨道4

重要

> routes.rb

match "/businesses" => "application#index",via: :options

注意：新条目匹配Angular服务器将发送的OPTIONS请求，以预先发送POST请求的开始。

> application_controller.rb

class ApplicationController < ActionController::Base


before_filter :set_headers

def index
  puts "Do nothing."
  render nothing: true
end

def set_headers
  puts 'ApplicationController.set_headers'
  if request.headers["HTTP_ORIGIN"]     
  # better way check origin
  # if request.headers["HTTP_ORIGIN"] && /^https?:\/\/(.*)\.some\.site\.com$/i.match(request.headers["HTTP_ORIGIN"])
    headers['Access-Control-Allow-Origin'] = request.headers["HTTP_ORIGIN"]
    headers['Access-Control-Expose-Headers'] = 'ETag'
    headers['Access-Control-Allow-Methods'] = 'GET,POST,PATCH,OPTIONS,HEAD'
    headers['Access-Control-Allow-Headers'] = '*,x-requested-with,If-Modified-Since,If-None-Match,Auth-User-Token'
    headers['Access-Control-Max-Age'] = '86400'
    headers['Access-Control-Allow-Credentials'] = 'true'
  end
end               
end

>我的Rails控制器

def create
  puts 'Businesses_controller.create!!!!!'
  puts business_params.inspect

  # business_type object is recovered from db
  businessTypeName = params[:type]    
  businessType = BusinessType.where(:name => businessTypeName).first
  ...
end
