验证服务器地址的有效性mp.weixin.qq.com/wiki/17/2d4265491f12608cd170a95559800f2d.html#.E7.AC.AC.E4.BA.8C.E6.AD.A5.EF.BC.9A.E9.AA.8C.E8.AF.81.E6.9C.8D.E5.8A.A1.E5.99.A8.E5.9C.B0.E5.9D.80.E7.9A.84.E6.9C.89.E6.95.88.E6.80.A7

token 可由开发者在开发者中心配置项任意填写timestamp 时间戳nonce 随机数

加密/校验流程如下：

  1. 将token、timestamp、nonce三个参数进行字典序排序

  2. 将三个参数字符串拼接成一个字符串进行sha1加密

  3. 开发者获得加密后的字符串可与signature对比，标识该请求来源于微信
