① 确认自己的生成的signature是否正确
在微信提供的http://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=jsapisign进行校验
② wx.config中使用的noncestr, timestamp与用以签名中的对应noncestr, timestamp是否一致一致…如上面（一.服务器代码）
（有可能因为JS页面加载顺序问题，服务器生成的signature，noncestr，timestamp在wx.config中没有获取到）。
③ 确认url是页面完整的url，包括GET参数部分
需要去掉#后面的部分
④ config 中的 appid 与用来获取 jsapi_ticket 的 appid 是否一致
⑤ 报错｛errmsg：config:ok}是debug的正常返回把调试模式关掉就OK
wx.config debug: false,
