使用 vue js 和 axios 上传多个文件

wea*_*ver 6 laravel vue.js axios

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(){
    });
  },

你忘了使用$refs. 添加ref到您的输入:

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

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];
        formData.append('files[' + i + ']', file);
    }

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

这应该是有效的。
