vue + axios + formdata 上传文件带参数的爬坑之路

submitform(event) {
 let formdata = new formdata()
 formdata.append('name', this.name)
 formdata.append('age', this.age)
 formdata.append('file', this.file)
let config = {
   headers: {
    'content-type': 'multipart/form-data;boundary = ' + new date().gettime()
    } 
}
 this.$http.post('/myupload', formdata, config).then(function (res) {
    if (res.status === 2000) {
     /*这里做处理*/
    }
 })
}
