最开始 代码是

//network.js

function POST(url,params) {

wx.request({

url: url,

data: params,

method: 'GET',

success: function (res) {

console.log('返回结果：')

console.log(res.data)

return res.data

}

})

}

//login.js

const network = require('../../../utils/network.js');

...

//登录

login: function (login_res) {

login_res = login_res.detail.value

var url = app.globalData.baseUrl + 'api/login'

var params = {

username: login_res.username,

password: login_res.password

}

var user_data = network.POST(url,params)

console.log(user_data)

}

发现这取不到值，因为小程序的请求是异步的。

查资料说需要用到promise

查资料+摸索

最终代码如下：

//network.js

const app = getApp()

function POST(url, params) {

let promise = new Promise(function (resolve, reject) {

wx.request({

url: url,

data: params,

method: 'POST',

success: function (res) {

console.log('返回结果：')

console.log(res.data)

app.netWorkData.result = res.data

resolve();

}

})

});

return promise

}

module.exports = {

POST: POST

}

//app.js

App({

netWorkData:{

result: { code: -1, msg: '发起请求失败' }

}

})

//登录

login: function (login_res) {

login_res = login_res.detail.value

var url = app.globalData.baseUrl + 'api/login'

var params = {

username: login_res.username,

password: login_res.password

}

network.POST(url,params).then(() => {

//请求成功的操作

var user_data = app.netWorkData.result

});

},

成功oooojbk
