<!DOCTYPE html>
<html lang="en">
  <head>
    <title></title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
  </head>
  <body>
    <form method="post" action="/upload" enctype="multipart/form-data">
      <input type="text" name="name" value="" placeholder="请输入用户名">
      <input type="text" name="age" value="" placeholder="请输入年龄">
      <input type="file" name="uploadFile">
      <input type="submit" value="提交">
    </form>
  </body>
</html>

在vue中这种简单的表单提交其实使用的是 FormData 来模拟表单提交

<head>
  <title></title>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <script src="https://cdn.bootcss.com/vue/2.3.4/vue.js"></script>
  <script src="https://cdn.bootcss.com/axios/0.16.2/axios.js"></script>
</head>
 
<body>
  <form>
    <input type="text" value="" v-model="name" placeholder="请输入用户名">
    <input type="text" value="" v-model="age" placeholder="请输入年龄">
    <input type="file" @change="getFile($event)">
    <button @click="submitForm($event)">提交</button>
  </form>
 
  <script>
    window.onload = function () {
      Vue.prototype.$http = axios;
      new Vue({
        el: 'form',
        data: {
          name: '',
          age: '',
          file: ''
        },
        methods: {
          getFile(event) {
            this.file = event.target.files[0];
            console.log(this.file);
          },
          submitForm(event) {
            event.preventDefault();
            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'
              }
            }
 
            this.$http.post('/upload', formData, config).then(function (res) {
              if (res.status === 2000) {
                /*这里做处理*/
              }
            })
          }
        }
      })
    }
  </script>
</body>
