h5在微信内获取信息

按照文档配置后微信公众号


//通过自己后台写的接口拿到配置的appid
//拼接地址后跳转微信，成功将返回拼接的链接，并携带code参数，code只能用一次
axios.get('/api/wechat/get').then((response)=>{
          if (response.data.msg.code == 0) {
            this.appid  =  response.data.data
            let url = location.origin + location.pathname 

            console.log('获取=-=====appid')
            console.log(this.appid)
            console.log(url)
           
            window.location.href = 'https://open.weixin.qq.com/connect/oauth2/authorize?appid='+this.appid+'&redirect_uri='+url+'&response_type=code&scope=snsapi_base&state=123#wechat_redirect'
          }
        })


//通过拿到的code,走自己后台的接口，即可获得微信信息，有的需要授权，有的不需要
//例如获取openid
      if(this.$route.query.code){
        this.code = this.$route.query.code
        axios.get('/api/wechat/code2token?code='+this.$route.query.code).then((response)=>{
          if (response.data.msg.code == 0) {
            
            
            this.vxopenid = response.data.data.openid
           
          }
        })
        
      }
