使用 vue js 和 axios 上传多个文件 [英] Upload multiple file with vue js and axios

问题描述

我正在尝试使用 vuejs 和 axios 上传多个图像，但在服务器端我得到了空对象. 我在标题中添加了 multipart/form-data 但仍然是空对象.

submitFiles() {/*初始化表单数据*/让 formData = new FormData();/*遍历通过附加文件发送的任何文件到表单数据.*/for( var i = 0; i < this.files.length; i++ ){让文件 = this.files[i];控制台日志(文件)；formData.append('files[' + i + ']', file);}/*`在此处输入代码`向 POST/file-drag-drop URL 发出请求*/axios.post('/文件上传',表单数据，{标题:{'内容类型':'多部分/表单数据'},}).then(函数(){}).catch(函数(){});},

HTML:

<div class="form-group files text-center" ref="fileform"><input type="file" multiple="multiple"><span id='val'></span><a class="btn" @click="submitFiles()" id='button'>上传照片</a><h6>拖拽&在此处删除文件

我的服务器端代码:

class FileSettingsController extends Controller{公共功能上传(请求 $request){返回 $request->all();}}

输出:

{文件:[{}]}文件:[{}]0:{}

Console.log() 结果:File(2838972) {name: "540340.jpg", lastModified: 1525262356769, lastModifiedDate: Wed May 02 2018 17:29:16 GMT+0530 (India Standard Time), webkitRelativePath:87,"}

解决方案

您忘记使用 $refs.将 ref 添加到您的输入中:

接下来，像这样访问您的文件:

submitFiles() {让 formData = new FormData();for( var i = 0; i < this.$refs.file.files.length; i++ ){让文件 = this.$refs.file.files[i];formData.append('files[' + i + ']', file);}axios.post('/fileupload', formData, {标题:{'内容类型':'多部分/表单数据'},}).then(函数(){}).catch(函数(){});},

这应该有效.

I am trying to upload multiple images using vuejs and axios but on server side i am getting empty object. I added multipart/form-data in header but still empty object.

submitFiles() {
    /*
      Initialize the form data
    */
    let formData = new FormData();

    /*
      Iteate over any file sent over appending the files
      to the form data.
    */
    for( var i = 0; i < this.files.length; i++ ){
      let file = this.files[i];
      console.log(file);
      formData.append('files[' + i + ']', file);
    }

    /*`enter code here`
      Make the request to the POST /file-drag-drop URL
    */
    axios.post( '/fileupload',
      formData,
      {
        headers: {
            'Content-Type': 'multipart/form-data'
        },
      }
    ).then(function(){
    })
    .catch(function(){
    });
  },

HTML:

<form method="post" action="#" id="" enctype="multipart/form-data">
    <div class="form-group files text-center" ref="fileform">
        <input type="file"  multiple="multiple">
        <span id='val'></span>
        <a class="btn"  @click="submitFiles()" id='button'>Upload Photo</a>
        <h6>DRAG & DROP FILE HERE</h6>
    </div>

My Server side code:

class FileSettingsController extends Controller
{
    public function upload(Request $request){
        return $request->all();
    }
}

Output:

{files: [{}]}
files: [{}]
0: {}

Console.log() result: File(2838972) {name: "540340.jpg", lastModified: 1525262356769, lastModifiedDate: Wed May 02 2018 17:29:16 GMT+0530 (India Standard Time), webkitRelativePath: "", size: 2838972, …}

解决方案

You forgot to use $refs. Add ref to your input:

<input type="file" ref="file" multiple="multiple">

Next, access your files like this:

submitFiles() {

    let formData = new FormData();

    for( var i = 0; i < this.$refs.file.files.length; i++ ){
        let file = this.$refs.file.files[i];
        formData.append('files[' + i + ']', file);
    }

    axios.post('/fileupload', formData, {
        headers: {
            'Content-Type': 'multipart/form-data'
        },
      }
    ).then(function(){
    })
    .catch(function(){
    });
},

This should be works.
