var _session_key = '';
const APP_ID = '';//这里输入你的小程序appid
const APP_SECRET = '';//这里输入你的小程序app_secret
App({
onLaunch: function () {
var that = this
//调用登录接口
wx.login({
success: function (res) {
var code = res.code;
wx.request({
//获取openid接口
url: 'https://api.weixin.qq.com/sns/jscode2session',data: {
appid: APP_ID,secret: APP_SECRET,js_code: code,grant_type: 'authorization_code'
},method: 'GET',success: function (res) {
_openid = res.data.openid;//获取到的openid
_session_key = res.data.session_key;//获取到session_key
console.log(_openid)
}
})
