接口参数说明

参数类型参数名称是否必须具体描述Stringaktrue开发者密钥Stringsnfalse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）Stringlocationtrue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|….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格式的数据;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。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。
