我想知道如何以编程方式从javascript调用页面并为用户实现单点登录，cookie会发生什么？？
有关如何通过脚本或任何其他方法登录用户的任何建议。
答案 0 :(得分：1)
如果您使用JavaScript XMLHttpRequest（http://www.w3schools.com/xml/xml_http.asp），则浏览器的cookie将随请求一起发送到服务器。此外，服务器在其响应中返回的任何cookie都将添加到浏览器会话中。因此，如果您使用此机制登录用户，则基于cookie的身份验证应该有效。
请注意，您只能在下一页加载后使用document.cookies从JavaScript中读取这些响应Cookie。
