In spring boot, GET request is returning 200 but POST request is returning 403-CodePudding

I've a spring boot application with springdoc-openapi-ui dependency, and without security. The HTTP GET request is going through (status 200). But the HTTP POST request is not going through (status 403). What could be the reason for the 403 return code on the POST request?

swagger

CodePudding user response：

Either you have to use @RequestAttribute within your test method or you have to remove String string argument :

@RequestMapping(value = "/test", method = RequestMethod.POST,@RequestAttribute(value = "string") String string)
    public String test(String string) {
        log.info("/test");
        return "ok !!";
    }

CodePudding user response：

RequestParam annotation is missing. Please use below method. You need to invoke POST method with request param key string

And ResponseBody annotation is also missing.

@Operation(summary = "test")
        @RequestMapping(value = "/test", method = RequestMethod.POST)
        public @ResponseBody String test(@RequestParam("string") String string) {
            log.info("/test");
            return "ok !!";
        }
