请求参数
请求参数包括必选和可选参数，如不填写可选参数将使用其默认值，参数之间使用&进行分隔。
key
用户认证key，请参考如何获取你的KEY。支持数字签名方式进行认证。例如 key=123456789ABC
location
需要查询地区的LocationID或以英文逗号分隔的经度,纬度坐标（十进制），LocationID可通过城市搜索服务获取。例如 location=101010100 或 location=116.41,39.92
lang
多语言设置，默认中文，当数据不匹配你设置的语言时，将返回英文或其本地语言结果。
zh中文, 默认en英语fr法语es西班牙语ja日语ko韩语- 查看更多语言代码
gzip
对API接口进行压缩，可以极大的减少API接口访问延迟，减少缓存空间，提高接口连接成功率。默认开启gzip
y使用gzip方式压缩，默认n不使用压缩
