普通的Web开发,都是把sessionid保存在cookie中传递的。 不管是java还是php,服务端的会在response的header中加上Set-Cookie Response Headers Content-Type:application/json;charset=UTF-8 Date:Mon, 02 Apr 2018 16:02:42 GMT Set-Cookie:JSESSIONID=781C7F500DFA24D663BA243A4D9044BC;path=/yht;HttpOnly
浏览器的请求也会在header中加上 Request Headers Accept:*/* Accept-Encoding:gzip, deflate, br Accept-Language:zh-CN,zh;q=0.8 Cache-Control:no-cache Connection:keep-alive Content-Length:564 content-type:application/json Cookie:JSESSIONID=781C7F500DFA24D663BA243A4D9044BC;path=/yht;HttpOnly
通过这个sessionid就能使浏览器端和服务端保持会话,使浏览器端保持登录状态 但是,微信小程序不能保存Cookie,导致每次wx.request到服务端都会创建一个新的会话,小程序端就不能保持登录状态了 简单的处理方法如下: 1、把服务端response的Set-Cookie中的值保存到Storage中 wx.request({ url: path, method:method, header: header, data:data, success:function(res){ if(res && res.header && res.header['Set-Cookie']){ wx.setStorageSync('cookieKey', res.header['Set-Cookie']);//保存Cookie到Storage } }, fail:fail }) wx.request再从Storage中取出Cookie,封装到header中 let cookie = wx.getStorageSync('cookieKey'); let path=conf.baseurl+url; let header = { }; if(cookie){ header.Cookie=cookie; }
wx.request({ url: path, method:method, header: header, data:data, success:success, fail:fail })
