‘getLocation‘

});//签名的生成方法在附录1//你需要access_token，这个用来获取jsapi_ticket。//获取access_token需要用到appId和appsecrect。//获取到后就是签名(sign).//签名需要的参数有：jsapi_ticket，noncestr，timestamp及url(当前的url)//采用字段名的ASCII码升序，使用URL键值对的格式(key=value&key=value)拼接//如：jsapi_ticket=xxx&noncestr=xxx×tamp=xxx&url=xxx//最后对拼接出来的字符串用sha1签名，得到sign。放入config的参数里。首先获取accesstoken，
