前些天知道了如何获取数字签名SHA1，那它用来干嘛的呢？今天就来学习一下它的用处。
比如说我们要开发一款基于位置的服务，如地图、天气预报等。我们要用到API Key。

百度API Key申请地址：http://lbsyun.baidu.com/apiconsole/key

创建应用如图：
这里写图片描述
提交后得到API Key 如图：

接口实例：http://api.map.baidu.com/telematics/v3/weather？location=南昌&output=json&ak=你的API Key&mcode=你的数字签名SHA1;com.example.administrator.jsontest（包名）

接口参数说明

参数类型参数名称是否必须具体描述Stringlocationtrue输入城市名或经纬度，城市名如北京或者131，经纬度格式为lng，lat坐标，如：location=116.305145,39.982368;全国值为all，返回省会城市自治区，港澳台天气情况多城市天气预报中间用“|”分隔，如：location=116.305145,39.982368|123.342323,36238945|...Stringoutputfalse输出的数据格式，默认为xml格式，当output设置为json时，输出的为json数据格式Stringcoord_typefalse请求参数坐标类型，默认为gcj02经纬度坐标。允许的值为bd09ll、bd09mc、gcj02、wgs84；

返回的JSON数据
