vue中实现图片和文件上传的示例代码

<input type="file" value="" id="file" @change='onUpload'>//注意不能带括号

methods: {
//上传图片
onUpload(e){
      var formData = new FormData(); 
    f ormData.append('file', e.target.files[0]);
    formData.append('type', 'test');
      $.ajax({
        url: '/ShopApi/util/upload.weixun'，//这里是后台接口需要换掉
        type: 'POST',
        dataType: 'json',
        cache: false,
        data: formData,
        processData: false,
        contentType: false,
        success: (res) => {        
          if (res.code === 200) {
            var img_tpl ='<p class="picture" style="width:108px;float:left;">@@##@@<span class="r-span"
 onclick = "onDeletePicture()" style="color:#49BDCC;display:block;float:left;margin-left:10px;line-height:48px;">删除</span></p>';
            $("#refund_img").after(img_tpl);
          }
        },
        error: function(err) {
        alert("网络错误");
        }
      });
} 
}
