小程序登录+DouPHP笔记

发送请求

var inurl = app.globalData.url + "m/wechat_api.php?rec=index&page=1&num=8&username=" + app.globalData.userid;
this.http(inurl, 10, this.callback);

  http:function(category,count,callback){
    wx.request({
      url: inurl,
      data: {},
      header: {
        'content-type': 'application/json' // 默认值
      },
      success: function (res) {
        callback(res.data)
      }
    })
  },
  callback:function(res){
    //数据处理
  }

小程序服务器端

第二次进入判断登录态有没有失效？本地缓存有没有失效有一方失效都需要重新登录

小程序执行顺序是双线程执行 业务逻辑自己把握

// app.js执行
    var that = this;
    wx.checkSession({
      success: function (res) {
        console.log("登录态没失效");
        //获取用户3rd_session
        var rd3_session = wx.getStorageSync('3rd_session');
        wx.request({
          url: "https://xxxxx.com/m/wechat_api.php?rec=getsession",
          data: {
            "rd3_session": rd3_session
          },
          method: 'GET',
          success: function (res) {
            if (!res.data) {
              console.log('本地缓存已经失效');
              app.globalData.canIUse = 1;
              that.jz_index();
              //console.log(that.globalData.canIUse);
            } else {
              console.log('本地缓存没有失效,不需要重新登录');
              app.globalData.logininfo = res.data;
              app.globalData.userid = res.data.user_name;
              console.log(app.globalData.userid);
              that.jz_index();
            }
          }
        })
      },
      fail: function (res) {
        console.log("需要重新登录");
        app.globalData.canIUse = 1;
        that.jz_index();

      }
    })
    // app.js执行end
