python - 如何保持愉快的 session 彼此不同

Question

我正在努力让愉快的 session 来做我想做的事情。我有一个与用户进行单独聊天的应用程序(每个对话都有一个唯一的 dlg_nbr)。它似乎工作正常(参见下面日志输出中的前两个周期)，直到单独的对话混合在一​​起(当我同时发布时)，并且在 user2 的响应之前，user1 开始获得针对 user2 的响应(日志输出中的第三个周期)已处理。

我本以为，如果我的主函数 (think() ) 使用并返回一个 dlg_nbr，对于每个用户来说都是唯一的，我将其存储为 session [dlg_nbr]，这将确保跨响应/请求周期的连续性，该 session 是每个用户都是唯一的，对吗？

我知道cherrypy的多线程可能意味着事情是并行处理的，但是 session 肯定不应该混合吗？这让我抓狂，这是 Cherrypy 的一个功能吗？我做错了什么？

cherrypy代码

class Web:

    def rsp(self, stm=''):

        print '    10 SESSION ID ON REQUEST', cherrypy.session.id
        dlg_nbr = cherrypy.session.get('dlg_nbr')

       # main logic of app
        rsp, dlg_nbr = B.think(stm, dlg_nbr)

        print '    20 SESSION ID AFTER PROCESSING REQUEST', cherrypy.session.id
        cherrypy.session['dlg_nbr'] = dlg_nbr

    return rsp

if __name__ == '__main__':
    cherrypy.config.update(
         {'server.socket_host': config.HOST,
         'server.socket_port': config.PORT})

    STATIC_DIR = os.path.join(os.path.abspath("."), u"static")
    dev_config = {
        '/': {'tools.caching.on': False, 'tools.sessions.on': True},
        '/static': {'tools.staticdir.on': True,
        'tools.staticdir.dir': STATIC_DIR}}

    cherrypy.quickstart(Web(), config=dev_config)

ajax 帖子:

$.ajax({
            url: '/rsp',
            data: {stm: input_string},
            type: "POST",
            timeout: 10000,
            success: function(response) {......}

日志输出:

我现在解决了这个问题。为了方便起见，我将值分配给临时全局变量。看来这些是在cherrypy的多个线程之间共享的。解决方案是不使用全局变量，而是在局部范围内显式声明变量。现在工作正常
