很想吐槽现在支付，文档资料不全，写的东西有误，文档让我给value字段用URL Encodeing，按照文档做结果无法完成通知，后来删掉所有的URL Encoding才解决问题。

而且返回参数的方式奇葩，必须用payload的模式来获取返回值，还得装一个额外的组件

https://github.com/thinkjs/think-payload

可以用这个组建来获取数据，安装流程参考github的说明，需要在中间件内加一个解析器，在middlewares.js内，增加在 Think.js的payload 解析器后面。

  {handle: 'payload',options: {keepExtensions: true,limit: '5mb'}},// 《---------------加在这儿{handle: payload,options: {extendTypes: {json: ['application/x-javascript'], // will parse application/x-javascript type body in the same way as JSON typeform: ['application/thinkjs-form'], // will parse application/thinkjs-form type body in the same way as form typetext: ['application/thinkjs-text'], // will parse application/thinkjs-text type body in the same way as text typemultipart: ['application/thinkjs-multipart'], // will parse application/thinkjs-multipart type body in the same way as multipart-form typexml: ['application/thinkjs-xml'], // will parse application/thinkjs-xml type body in the same way as xml type}}},  {handle: 'router',options: {}},'logic','controller'

好了，接下来就是实现代码（Controller）：

const Base = require('./base.js');
const crypto = require('crypto');
const { ctx } = require('./base.js');
const ThinkSessionFile = require('think-session-file');
const { Console } = require('console');
const { request } = require('http');
const { version } = require('os');module.exports = class extends Base {sort(map){let keys = new Array();for( var key in map ) {keys.push( key );}keys.sort();let new_map = new Map();keys.forEach(key => {new_map[key] = map[key];})return new_map;}signature(map, key) {let result = '';for( var mapkey in map ){if( mapkey == 'signature'    || mapkey == 'mhtSignature' || map[mapkey] == '' ) {continue;}result = result + mapkey + '=' + map[mapkey] + '&';}let hex = crypto.createHash('md5').update(key   ).digest("hex");result += hex;console.log( result );result  = crypto.createHash('md5').update(result).digest("hex");return result;}datetime_string(){let now     = new Date();let day     = now.getDate();let month   = now.getMonth() + 1; let year    = now.getFullYear();let hour    = now.getHours();let minuate = now.getMinutes();let second  = now.getSeconds();String( month   ).length < 2 ? ( month   = "0" + month   ) : month;String( day     ).length < 2 ? ( day     = "0" + day     ) : day;String( hour    ).length < 2 ? ( hour    = "0" + hour    ) : hour;String( minuate ).length < 2 ? ( minuate = "0" + minuate ) : minuate;String( second  ).length < 2 ? ( second  = "0" + second  ) : second;let result = year + "" + month + "" + day + "" + hour + "" + minuate + "" + second;return result;}async submitAction(){// 客户端上传，get方式let account         = this.get('account');let item_name       = this.get('item_name');    // 商品识别码let count           = this.get('count');let pay_type        = this.get('pay_type');let comment         = this.get('comment');if( think.isEmpty(account)   ||think.isEmpty(item_name) || think.isEmpty(count)     ||think.isEmpty(pay_type) ){return this.fail( 6000, "invalid argument" );}if( think.isEmpty(comment) ) {comment = '';}// 查询得到商品的数据（这部分自己实现）let item = await this.model('commodity', 'mysql_nova').find_item( item_name );if( think.isEmpty(item) ) {return this.fail( 6001, "invalid item" );}        // 填充商品数据let detail          = item.name + " * " + count;                       // 比如xxx * 3let sale_off        = item.sale_off;let original_price  = item.price * count;let actual_price    = original_price * sale_off;// 创建订单并插入到数据库中（这部分自己实现）let order_id = await this.model('order', 'mysql_nova').save(account, item_name, detail, count, original_price, actual_price, sale_off, comment );if( think.isEmpty(order_id) ) {return this.fail( 6002, "create order failed" );}// 生成订单的签名字符串let map = new Map();map['appId']                = think.config('pay.appid');map['funcode']              = 'WP001';map['version']              = '1.0.3';map['mhtOrderType']         = '05';map['deviceType']           = '01';map['mhtOrderNo']           = order_id.toString();map['mhtOrderName']         = item_name;map['mhtReserved']          = item_name;map['mhtOrderDetail']       = detail;map['mhtOrderAmt']          = actual_price;map['mhtOrderStartTime']    = this.datetime_string();map['payChannelType']       = pay_type;map['mhtCurrencyType']      = think.config('pay.currency');map['mhtOrderTimeOut']      = think.config('pay.timeout');map['notifyUrl']            = think.config('pay.notify');map['mhtCharset']           = think.config('pay.charset');map['mhtSignType']          = think.config('pay.signtype');map['mhtSubAppId']          = think.config('pay.subappid');map['consumerCreateIp']     = this.ctx.ip;map = this.sort( map );let sign = this.signature( map, think.config('pay.key') );map['mhtSignature']         = sign;let launch = true;let result = "";for( var key in map ){if( launch != true ) {result += '&';}result = result + key + '=' + map[key]; launch = false;}        return this.json(result);}async notifyAction(){// 回调通知// should install think-payload first.// detail: https://github.com/thinkjs/think-payloadlet info = this.ctx.request.body;if( think.isEmpty(info) ) {return this.json('success=N, extract body post failed');}console.log( 'notify info', info );// 拆分字符串let array = info.split('&');let map = new Map();array.forEach(key => {let pair = key.split('=');map[pair[0]] = decodeURIComponent(pair[1]);});map = this.sort( map );let secret = this.signature( map, think.config('pay.key') );if( secret != map['signature'] &&secret != map['mhtSignature'] ) {return this.json('success=N, signature failed.');}// 检验校验码通过，接下来就需要判断是否支付成功，// 订单号是否正确let state      = map['tradeStatus'];let order_id   = map['mhtOrderNo'];let payment_sn = map['nowPayOrderNo'];if( state == 'A001' ){// （数据库的更新自己实现）let retval = await this.model('order', 'mysql_nova').update_payment(order_id, payment_sn);if( retval == 1 ) {return this.json('success=Y');}}return this.json('success=N, invalid state or order id');}}

这个代码测试了可用，config需要自己去重新配。这儿就不累述了。
