我有一个 Rails 服务为我的 AngularJS 前端应用程序返回数据。该服务配置为通过返回足够的 header 来允许 CORS 请求。

当我发出 GET 请求以接收数据时，CORS header 以及我之前在登录时收到的 session cookie 被发送，您可以自己查看:

Request URL:http://10.211.194.121:3000/valoradores
Request Method:GET
Status Code:200 OK

一切正常，我取回了我的数据。

但是当我发出 POST 请求时，CORS header 和 session cookie 都没有随请求发送，并且 POST 在服务器上被取消，因为它没有 session 标识符。这些是请求的 header :

Request URL:http://10.211.194.121:3000/valoraciones

Request Headers
Accept:application/json, text/plain, */*
Cache-Control:no-cache
Content-Type:application/json;charset=UTF-8

X-Requested-With:XMLHttpRequest

Request Payload
{valoracione:{revisiones_id:1, valoradores_id:1}}
valoracione: {revisiones_id:1, valoradores_id:1}

并且服务以 403 响应，因为请求不包含 session cookie。

我不知道为什么 POST 请求会失败，因为 $resource 的配置就像另一个一样，我已经为 $httpProvider 定义了默认值来发送凭据(并且它在 GET 请求成功时正常工作):

  .config(['$httpProvider', function($httpProvider) {
     $httpProvider.defaults.withCredentials = true;
    }])

这是我在实例上调用 $save() 时失败的资源:

'use strict';

angular.module('gestisolApp')
  .service('ValoracionesService', ['$resource', 'API_BASE_URL', function ValoracionesService($resource, API_BASE_URL) {
    this.valoraciones = $resource(API_BASE_URL + '/valoraciones');
  }]);

这是通过 query() 调用成功的服务:

'use strict';

angular.module('gestisolApp')
  .service('ValoradoresService', ['$resource', 'API_BASE_URL', function ValoradoresService($resource, API_BASE_URL) {
    this.valoradores = $resource(API_BASE_URL + '/valoradores');
  }]);

它们很像。

有人知道为什么在没有 session cookie 的情况下发送 POST 吗？

编辑

只是为了完成信息，预检通过以下方法处理，并且处理正常，因为失败的 POST 之前的请求是一个成功的 OPTIONS，并返回 200 响应代码:

def cors_preflight_check
        headers['Access-Control-Allow-Origin'] = 'http://10.211.194.121:8999'
        headers['Access-Control-Allow-Methods'] = 'GET,POST,OPTIONS'
        headers['Access-Control-Allow-Headers'] = 'X-Requested-With,X-Prototype-Version,Content-Type,Cache-Control,Pragma,Origin'
        headers['Access-Control-Allow-Credentials'] = 'true'
        headers['Access-Control-Max-Age'] = '1728000'
        render :nothing => true, :status => 200, :content_type => 'text/html'
end

这是失败 POST 之前的 CORS OPTIONS 请求/响应交换:

Request URL:http://10.211.194.121:3000/valoraciones
Request Method:OPTIONS
Status Code:200 OK

最佳答案

我有一个类似的问题，在 Angular $http CORS 请求解决问题之前添加以下内容。 $http.defaults.withCredentials = true;

引用https://developer.mozilla.org/en-US/docs/HTTP/Access_control_CORS#Requests_with_credentials了解更多详情。

关于javascript - XmlHttpRequest CORS POST 不带 cookie 发送，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19770359/
