八、适合小白的小程序之设置全局请求函数及请求路径

 globalData: {
    userInfo: null,
    statusBarHeight: wx.getSystemInfoSync()[‘statusBarHeight‘],
    URL: ‘http://www.baidu.com‘　　　　　　---这里写你要设置的全局请求路径
  },

wxRequest(method, url, data, callback, errFun) {
    wx.request({
      url: url,
      method: method,
      data: data,
      header: {
        ‘content-type‘: method == ‘GET‘ ? ‘application/json‘ : ‘application/x-www-form-urlencoded‘,
        ‘Accept‘: ‘application/json‘
      },
      dataType: ‘json‘,
      success: function (res) {
        callback(res.data);
      },
      fail: function (err) {
        errFun(res);
      }
    })
  },

使用方法：
app.wxRequest(‘POST‘, app.globalData.URL + ‘/aaa‘, data, (res) => {
      console.log(res)
      
    }, (err) => {
      console.log(err.errMsg)
    });
