<div id="app">
<input class="file" name="file" type="file" accept="image/png,image/gif,image/jpeg" @change="update"/>
</div>
<script>
var vm = new Vue({
el: '#app',
methods: {
update: function (e){
let file = e.target.files[0];
let param = new FormData(); //创建form对象
param.append('file',file);//通过append向form对象添加数据
console.log(param.get('file')); //FormData私有类对象，访问不到，可以通过get判断值是否传进去
let config = {
headers:{'Content-Type':'multipart/form-data'}
}; //添加请求头
this.$http.post('http://127.0.0.1:8080/api/create/upload',param,config)
.then(response=>{
console.log(response.data);
})
}
}
})
</script>
</body>
</html>
