前端上传文件一直报错，后端显示读文件出问题，怎么解决？

Question

前端上传文件一直报错，后端显示读文件出问题，刚进函数在绑定参数的时候就出了问题返回了

明明都能打印出来但文件就是上传不上去，服务器会报错
400 {"msg": "multipart: NextPart: EOF",
"code": 40日，
"data": null}
400 {"msg": "multipart: NextPart: EOF"，"code": 400,
"data": null}

跟后端给的接口参数也是一样的

handleFileChange(event) {            this.upfile = event.target.files[0];        },        uploadCourseMaterial() {            if (!this.upfile) {                alert("请先选择文件");                return;            }            const  formData = new FormData();            formData.append('file', this.upfile);             formData.append('courseId', parseInt(this.courseId));             formData.append('parentId', parseInt(this.parentId));             formData.append('private', this.isPrivate.toString());             formData.append('folder', this.isFolder.toString());             formData.append('filePic', parseInt(this.filePicId));             formData.append('folderName', this.folderName);             console.log(formData.get('file'))            console.log(formData.get('courseId'))            console.log(formData.get('parentId'))            console.log(formData.get('private'))            console.log(formData.get('folder'))            console.log(formData.get('filePic'))            console.log(formData.get('folderName'))            const boundary = '----' + Math.random().toString(36).slice(2, 17);             axios.post('/api/course/uploadFile', formData,{                headers: {                    'Content-Type': `multipart/form-data; boundary=${boundary}`,                    Authorization: this.$store.state.teacher.teacherData.token,                }            })            .then(response => response.json())            .then(data => {                // 处理响应数据                console.log(data);                alert("上传成功！");                this.clear();            })            .catch(error => {                console.error('Error:', error);                alert("上传失败，请重试！");            });    },
