百度天气预报接口使用详细

百度提供天气预报查询接口API，可以根据经纬度/城市名查询天气情况，我们可以在微信公众平台开发中调用这一接口。

接口说明

根据经纬度/城市名查询天气的结果

接口示例

http://api.map.baidu.com/telematics/v3/weather?location=北京&output=json&ak=5slgyqGDENN7Sy7pw29IUvrZ

接口参数说明

参数类型	参数名称	是否必须	具体描述
String	location	true	输入城市名或经纬度，城市名称如: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"|"分 隔,location=116.305145,39.982368| 122.305145,36.982368|….
String	output	false	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格式的数据;
String	coord_type	false	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。bd09ll表示百度经纬度坐标，bd09mc表示百度墨卡托坐标，gcj02表示经过国测局加密的坐标。wgs84表示gps获取的坐标。
