代码如下所示：

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <meta http-equiv="X-UA-Compatible" content="ie=edge">

        <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
        <script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.0.min.js"></script>
        <script src="https://cdn.staticfile.org/vue-resource/1.5.1/vue-resource.min.js"></script>
    </head>
    <body>
        <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>

最后的结果如下：
