微信小程序爬坑

1、app.json配置信息是怎样的？

{
  "pages":[
    "pages/页面1/页面1",
    "pages/页面2/页面2",
  ],
  "window":{
    "backgroundTextStyle":"light",//文本背景样式
    "navigationBarBackgroundColor": "White",//导航背景颜色
    "navigationBarTitleText": "WeChat",//导航背景标题
    "navigationBarTextStyle":"black",//导航背景文本样式
    "enablePullDownRefresh": true//是否开启下拉刷新
  },
  "tabBar": {//底部菜单栏最多5个
    "color": "#000",
    "selectedColor": "#000000",
    "backgroundColor": "#efefef",
    "borderStyle": "White",
    "list": [{
        "pagePath": "pages/shopping/shopping",
        "iconPath": "images/scshop_i.png",
        "selectedIconPath": "images/scshop.png",
        "text": "商城"
      },{
        "pagePath": "pages/shopcar/shopcar",
        "iconPath": "images/shopca.png",
        "selectedIconPath": "images/shopcar.png",
        "text": "购物车"
      },{
      "pagePath": "pages/index/index",
      "iconPath": "images/latest.png",
      "selectedIconPath": "images/latest_on.png",
      "text": "我的"
    }]
  },
"networkTimeout": {//网络请求时间
  "request": 20000,
  "connectSocket": 20000,
  "uploadFile": 20000,
  "downloadFile": 20000
},
"debug":true
}

2、如何获取用户的身份信息？

var appUserinfo;
var openid = '';
var sessionkey = '';
var encryptedData = '';
var iv = '';
App({
//用户登录
getUserInfo: function (callback) {
    //调用登录接口
  var retuser = {};
  var that = this;
  wx.showLoading({ title: "加载中..." });
    wx.login({
      success: function (res) {
        var code = res.code;
        if (code) {
          //读取会员信息
          wx.request({
            url: "https"+aspx,// 通过获取code来换取session_key
            data: {
              code: code,
            },
            success: function (res) {//res返回值获得session_key&openid
              console.log(res)
              var retdata = res.data.data;
              openid = retdata.openid,
                sessionkey = retdata.session_key;
              //设置微信用户信息
              wx.getUserInfo({
                success: function (res) {
                  encryptedData = res.encryptedData;
                  iv = res.iv;
                  appUserinfo = res.userInfo
                  wx.request({
                    url: "https"+aspx,//通过session_key来换取公众号信息
                    data: {
                      openid:openid,
                      unionid:encryptedData,//解析unionid(md5加密&解密获得)
                      sessionkey:sessionkey,
                      iv:iv,
                      appid: 'wx758e9825590dc405'
                    },
                    dataType: "json",
                    success: function (ret) {
                      wx.hideLoading();
                      var retdata = ret.data;
                      for (var key in retdata) {
                        retuser[key] = retdata[key];
                      }
                      retuser.littleid = retuser.uid;//换取公众平台用户的id信息
                      retuser.openid=openid;
                      callback && callback(retuser);
                    }
                  });
                },
                fail: function (res) {
                  var that = this
                  console.log(res)
/*
                  wx.redirectTo({
                    url: '/pages/error/error?error=请同意获得微信用户信息'
                  })
*/if(res){//res返回值来检查用户授权信息&重新授权
  wx.showModal({
    title: '警告',
    content: '若不授权微信登陆，您将无法使用商城部分功能,点击重新获取授权',
    success: function () { 
      wx.openSetting({
        success: function (res) {
          if (!res.authSetting["scope.userInfo"] || !res.authSetting["scope.userLocation"]) {
            wx.getUserInfo({})
          }
        }
      })
    }
  })
}
                }
              })
            }
          });
        }
      }
    })
}
})

以上就是我在初学小程序时所走的坑吧，分享给各位，希望对大家有所帮助
