从http链接使用Spring Boot获取值

Question

我想从这个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

我尝试实现这个Spring代码：

    @PostMapping(value = "/v1/notification")
    public String handleNotifications(@RequestParam("notification") String itemid) {
        // parse here the values
    return "result";
    }

Answer 1

对于requestparam您的控制器方法应该如下所示，以便从请求中获取值，您可以使用required=false使requestparam可选，并且还可以设置默认值(@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";
}
