laravel 使用 vue js 和 axios 上传多个文件

Upload multiple file with vue js and axios

提问by weaver

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.

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() {
    /*
      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:

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:

我的服务器端代码：

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

Output:

输出：

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

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

你忘记使用$refs. 添加ref到您的输入：

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

Next, access your files like this:

接下来，像这样访问您的文件：

submitFiles() {

    let formData = new FormData();

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

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

This should be work.

这应该是工作。

If anyone wondering, "How can I send also data with it", there you go:

如果有人想知道，“我怎样才能用它发送数据”，你去吧：

formData.append('name[' + this.name + ']', name);
formData.getAll('files', 'name');
