这篇文章主要介绍了微信小程序request请求封装，验签代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

1.公共文件util添加

request请求

//简单封装请求
function request(params, path, isShowLoading = true, goBack = false, type = 'none', obj={}) {
 try {
 console.log(path)
 let NowTime = Date.parse(new Date()) / 1000;
 let defaultParams = {
 platform: app.globalData.platform,
 appVersion: app.globalData.version,
 deviceId: uuId(),
 timestamp: params.timestamp ? params.timestamp : NowTime
 };
 
 params = Object.assign(params, defaultParams);
 let requestParams = signature(params)
 isShowLoading && wx.showLoading && wx.showLoading({
 title: '加
中...'
 })
 return new Promise((resolve, reject) => {
 let header;
 obj.header = obj.header || {};
 console.log('获取ptkey')
 console.log(plugin.getJdListStorage(['guid', 'pt_key', 'pt_token', 'pt_pin']))
 let [GUID = '', KEY = '', TOKEN = '', PIN = ''] = plugin.getJdListStorage(['guid', 'pt_key', 'pt_token', 'pt_pin']),
 _cookie = `guid=${GUID}; pt_pin=${encodeURIComponent(PIN)}; pt_key=${KEY}; pt_token=${TOKEN};${wx.getStorageSync("accessToken_v1")}`, {
 cookie
 } = obj.header;
 console.log(cookie)
 obj.header.cookie = cookie ? `${cookie};${_cookie}` : _cookie;
 if (!isEmpty(getToken())) {
 obj.header.authorization = 'Bearer ' + getToken()
 }
 console.log(obj.header)

 wx.request({
 url: getApp().globalData.host + path, //获取app.js 全局ip
 data: requestParams,
 method: 'POST',
 header: obj.header,
 success: function(res) {
 console.log(res)
 isShowLoading && wx.hideLoading && wx.hideLoading()
 // 缺少登录失效的处理方法
 if (res.statusCode == 200 && res.data.code == 200) {
 if (isEmpty(res.data.data) || res.data.data == true) {
 resolve('true')
 return
 }
 if (res.data.data) {
 resolve(res.data.data);
 } else if (res.data.data == 0){
 resolve(res.data.data);
 } else {
 resolve('true')
 }
 } else if (res.statusCode == 200 && res.data.code == 401) { //token过期
 Login();
 resolve(false);
 return;
 } else {
 //需要再判断code码
 // errorShow(res.data.msg, goBack, type);
 errorShow(res.data.msg);
 resolve(false);
 // reject(res.data.res);
 }
 },
 fail: function(err) {
 console.log(err)
 // 因为hide会让showToast隐藏
 isShowLoading && wx.hideLoading && wx.hideLoading()
 errorShow('网络请求失败');
 reject(new Error('Network request failed'))
 // throw new Error('Network request failed')
 },
 complete: function() {}
 })
 })
 } catch (err) {
 console.log(err)
 errorShow('网络请求失败');
 return false;
 }
}

2.signature 签名

//生成签名
function signature(params) {
 let keyArr = []
 for (let key in params) {
 keyArr.push(key)
 }
 let arr = keyArr.sort();
 let result = "";
 arr.map((item, index) => {
 if (params[item] == null || params[item] == undefined) {
 delete params[item];
 arr.splice(index, 1);
 }
 })
 console.log("arr")
 console.log(arr)
 arr.map((item, index) => {
 if (Array.isArray(params[item]) == true) {
 let res = ''
 let arr = params[item]
 arr.map(obj => {
 console.log(typeof(obj))
 if (typeof(obj) != 'object') {
 res += obj
 } else {
 for (let key in obj) {
 if (Array.isArray(obj[key])) {
 let val = '';
 obj[key].map(item => {
 val += item
 })
 res += key + val
 } else {
 res += key + obj[key]
 }
 }
 }
 })
 result += '' + item + '' + res
 } else {
 result += '' + item + '' + params[item]
 }
 })
 console.log("result")
 console.log(result)

 let pos;
 if (isEmpty(getToken())) {
 pos = result
 } else {
 pos = result + getToken()
 }
 console.log(pos)
 console.log("signature")
 let signature = sha256.hmac.create('pos_secret').update(pos).hex().toLowerCase(); //需要引入sha256.min.js
 console.log(signature)
 let obj = {
 'signature': signature
 }
 return Object.assign(params, obj);
}
