Angularjs 安古拉和饼干

我对AngularJS和cookies有些不完全理解

我有一个网址：https://ajax.foo.bar/helloworld.php 此url设置cookie，如果PHP文件找到cookie，则输出由DB生成：

{
   DbReturnBecauseOfCookie: "foo"
}

如果我加载https://ajax.foo.bar/helloworld.php 在我的浏览器中，它给我：DbReturnBecauseOfCookie:foo，因为cookie被设置为相同的浏览器和相同的url，我假设使用：

也应该输出DbReturnBecauseOfCookie:foo，但它不会输出DbReturnBecauseOfCookie:bar。这就好像服务器将Angular和我的open browser选项卡视为两个不同的实体

这怎么可能？如何让Angular使用浏览器中设置的cookie？

问题是CORS

在我的例子中，我使用的是NGINX，可以为NodeJS、Apache等找到等价的答案

location ~ .php$ { ## Execute PHP scripts
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' 'https://ajax.foo.bar';
            add_header 'Access-Control-Allow-Credentials' 'true';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
            add_header 'Access-Control-Max-Age' 1728000;
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            add_header 'Content-Length' 0;
            return 204;
         }

         if ($request_method = 'POST') {
            add_header 'Access-Control-Allow-Origin' 'https://ajax.foo.bar';
            add_header 'Access-Control-Allow-Credentials' 'true';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
         }

         if ($request_method = 'GET') {
            add_header 'Access-Control-Allow-Origin' 'https://ajax.foo.bar';
            add_header 'Access-Control-Allow-Credentials' 'true';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
         }

您是否为每个请求调用php中的session_start？我的helloworld.php是Magento，因此：yes@KostyaShkryob找到了
