var http = {    get:(url, obj = undefined) => {        var promise = new Promise((resolve, reject) => {            wx.request({                url: baseUrl+url,                method: 'GET',                header: {                    'content-type': 'application/x-www-form-urlencoded',                    'mid': mid,                    'token': token                },                data: obj,                success: (data) => {                    if (data.data.retcode == 1) {                        resolve(data.data)                    } else {                        console.log('前端故障');                        reject(data.errMsg)                    }                },                fail:(msg) => {                    console.log('后端故障')                    reject(data.errMsg)                }            })        })        return promise;    },    post: (url, obj) => {        var promise = new Promise((resolve, reject) => {            wx.request({                url: baseUrl+url,                method: 'POST',                header: {                    'content-type': 'application/x-www-form-urlencoded',                    'mid': mid,                    'token': token                },                data: obj,                success: (data) => {                    if (data.data.retcode == 1) {                        resolve(data.data)                    } else {                        console.log('前端故障');                        reject(data.errMsg)                    }                },                fail: (msg) => {                    console.log('后端故障')                    reject(data.errMsg)                }            })        })        return promise;    }}

先贴代码,自己修改,保存为common.js,在app.js中引用,在使用时直接调用htpp.get(url,obj)或者http.post(url,obj)即可,

这里封装了wx.request()方法,调用接口的返回值为promise对象,

小程序支持ES6的语法,可以使用promise(whatever).then((res)=>{whatever}).catch()的方法解决小程序函数并发的问题.

新手上路,有可改进的地方还不吝赐教.
