java - 使用 Spring Boot 从 http 链接获取值
问题描述
我想从此 http 链接获取值:
https://www.test.com/notification?con=41280440000097&dp=1232&type=single
https://www.test.com/notification?con=41280440000097&sec=1232
我试图实现这个 Spring 代码:
@PostMapping(value = "/v1/notification")
public String handleNotifications(@RequestParam("notification") String itemid) {
// parse here the values
return "result";
}
但是我如何解析 http 链接并在 HashMap 的 ArrayList 中获取值?
解决方案
你的控制器方法应该像这样RequestParam
从请求中获取值,你可以使RequestParam optional with
required=false and you can set default value also
(@RequestParam(value = "i", defaultValue = "10") int i`
@PostMapping(value = "/v1/notification")
public String handleNotifications(@RequestParam(value="con", required=false) String itemid, @RequestParam(value="dp", required=false) String dp, @RequestParam(value="type", required=false) String type )
{
// you can use all these values directly in this method
// parse here the values
return "result";
}
