参数类型 | 参数名称 | 是否必须 | 具体描述 |
---|---|---|---|
String | ak | true | 开发者密钥 |
String | sn | false | 若用户所用ak的校验方式为sn校验时该参数必须。 (sn生成算法) |
String | location | true | 输入城市名或经纬度,城市名称如:北京,经纬度格式为lng,lat坐标如: location=116.305145,39.982368;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。 |
