微信公号开发之：thinkjs踩坑checkSignature

checkSignature是用来验证微信服务器是否可以和自己的服务器通讯的狗玩意儿~~~~~

1. 参数的获取，这里的验证步骤得用this.get()获取参数;
2. 需要安装sha1包，npm install sha1;
3. 官方文档用的php代码演示，直接返回的布尔值。thinkjs直接返回布尔值会报以下错误{"errcode":-106,"errmsg":"token check fail"} 解决办法，return this.json();

  const sha1 = require('sha1');

  async checkSignatureAction () {

        let signature = this.get('signature');

        let echostr = this.get('echostr');

        let token = 'TOKEN';//公号后台配置的TOKEN

        let timestamp = this.get('timestamp');

        let nonce = this.get('nonce');

        let array = new Array(token, timestamp, nonce);

        array.sort();

        let str = array.toString().replace(/,/g, "");

        let code = sha1(str);

        if (code == signature) return this.json(echostr); 

        return this.json('error');
   }
