向Spring后端发送axios post请求时出现400错误

我有这些数据,我想发送到后端端点以执行一些数据库操作,现在的问题是,当我检查网络时,我可以看到请求确实启动了,并且确实包含了作为请求主体的数据,但不知何故,它告诉我,当它确实在请求主体中时,端点没有收到参数。

这是发送数据的函数,它从按钮内的value属性获取数据。

function sendThefknData(mangaId) {
        axios.post('/saveManga', {
            mangaId: mangaId
        })
            .then(response => {
                console.log('Manga saved successfully:', response.data);
            })
            .catch(error => {
                console.error('There was an error saving the manga:', error);
            });
    }

这是控制器端点

@PostMapping("/saveManga")
    public ResponseEntity<String> saveManga(@RequestParam("mangaId") String mangaId, HttpSession session) {
        try {
            Long userId = (Long) session.getAttribute("userId");
            if (userId == null) {
                return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body("User not logged in.");
            }

            System.out.println("Manga ID: " + mangaId);
            System.out.println("User ID from session: " + userId);

            usermangainfo.insertUserMangas(userId, mangaId);

            return ResponseEntity.ok("Manga saved successfully.");
        } catch (Exception e) {
            return ResponseEntity.status(HttpStatus.BAD_REQUEST).body("Error saving manga: " + e.getMessage());
        }
    }

老实说,我不知道会有什么问题,我试着用谷歌搜索,试着用chatgpt碰碰运气,但无济于事。 Network
