    现在有一个小应用，客户搜索一个词发出一个post请求，等页面加载完成之后立即通过ajax发出第二个请求

    第二个请求会用到第一个请求中的部分值
    虽然现在可以通过global这种方式设置全局变量，或者在第二个请求中再查询一下数据库，或者用jquery取得网页中的一些值，但感觉很不方便啊

    flask中的g对象和上下文是否能解决此问题？如何做到？
  • 请求
  • flask
  • 全局变量

    明显不能，因为第二个请求是页面加载完再请求的，g和上下文都取不到东西了
    cookies session什么的才适合

    存在客户端啊，js变量或者cookie
    服务端试试 flash()或者返回的url加参数
