路径变量@PathVariable

①获取指定路径变量：

 @GetMapping("/car/{id}/owner/{userName}")
    public Map<String,Object> getCar(@PathVariable("id") int id,
                         @PathVariable("userName") String userName){
        Map<String,Object> map = new HashMap<>();
        map.put("id",id);
        map.put("userName",userName);

        return map;
    }

 请求：http://localhost:8080/car/1/owner/zhangsan

返回：{"id":"1","userName":"zhangsan"}

②获取所有路径变量：

//使用map提取所有的路径变量，map必须是String类型
    @GetMapping("/car/{id}/owner/{userName}/{age}")
    public Map<String,String> getCar(@PathVariable() Map<String,String> kv){

        return kv;
    }

请求：http://localhost:8080/car/2/owner/lisi/30

返回：{"id":"2","userName":"lisi","age":"30"}

 

获取请求头@RequestHeader

①获取指定请求头

@GetMapping("/car/{id}/owner/{userName}")
    public Map<String,Object> getCar(@PathVariable("id") int id,
                         @PathVariable("userName") String userName,
                                    @RequestHeader("User-Agent") String userAgent){
        Map<String,Object> map = new HashMap<>();
        map.put("id",id);
        map.put("userName",userName);
        map.put("userAgent",userAgent);
        return map;
    }　

 

 请求返回：

 ②获取所有的请求头

@GetMapping("/car/{id}/owner/{userName}")
public Map<String,String> getCar(@PathVariable("id") int id,
                     @PathVariable("userName") String userName,
                                @RequestHeader Map<String,String> heads){

    return heads;
}
