我用axios上传视频出现错误

let fd = new FormData();

let data = this.sendData;

$.each(data, function (index, item) {

    fd.append(index, item);

});

let face_img = $('#face_img')[0].files[0];

if ($('#right_box').has('#self_content').length) {

    var cOntent= $('#self_content')[0].files[0];

}

let html_cOntent= this.sendData.html_content;

if (!content) {

    cOntent= html_content;

}

console.log(content);

fd.append('face_img', face_img);

fd.append('content', content);

let cOnfig= {

    headers: {'Content-Type': 'multipart/x-www-form-urlencoded'},

    onUploadProgress: function (e) {

        console.log(e);

    },

    timeout:999999

}

axios.post('/self_class/add_self', fd, config).then(function (res) {

    console.log(res);

});
