全国车辆违章数据接口_免费API接口调用-聚合数据

接口地址：http://v.juhe.cn/wz/citys

返回格式：json/xml/jsonp

请求方式：get post

请求示例：http://v.juhe.cn/wz/citys?key=key

接口备注：有些城市如果维护，我们会临时下线处理

请求参数说明：

名称	必填	类型	说明
province	N	string	默认全部，省份简写，如：ZJ、JS
dtype	N	string	返回数据格式：json或xml或jsonp,默认json
format	N	int	格式选择1或2，默认1
callback	N	String	返回格式选择jsonp时，必须传递
key	Y	string	在个人中心->我的数据,接口名称上方查看
