带有 axios 的 Quasar 框架上传器 [英] Quasar Framework Uploader with axios

问题描述

一个关于quasar框架上传组件的问题.我需要将图像发布到一个 URL，该 URL 将重命名上传的文件并返回完整路径.

A question about the quasar framework uploader component. I need to post the images to a URL that will rename the uploaded file and return the full path.

我正在使用 upload-factory 和 axios

但是我在理解如何将文件传递给 axios 时遇到问题，就好像它只是一个输入类型文件一样.基本上我需要把它做成如果我发送一个带有单个输入文件的表单，如下所示:

But I'm having problems understanding exactly how to pass the file to axios as if it was just an input type file. Basically I need to make it as If I'm sending a form with a single input file like this:

<input type="file" name="banner">

这是组件:

<q-uploader
  url=""
  extensions=".gif,.jpg,.jpeg,.png"
  :filter="filterFiles"
  :upload-factory="uploadFile" />

这是上传方法，但我不断收到来自服务器的错误响应.

This is the upload method, but I keep getting an error response from the server.

uploadFile (file, updateProgress) {
  const formData = new FormData()
  formData .set('banner', file)
  var headers = {
    'Content-Type': 'multipart/form-data'
  }
  axios.post('http://someurl/uploadFile', formData , headers)
    .then(function (response) {
      console.log(response)
    })
    .catch(function (response) {
      console.log(response)
    })
}

如果我发布一个带有 method="post" enctype="multipart/form-data" 和一个

If I post a plain html form with method="post" enctype="multipart/form-data" and a

<input type="file" name="banner">

我通过处理/上传的图像 URL 从服务器获得我的 OK 响应

I get my OK response from the server with the processed/uploaded image URL

推荐答案

我已成功将文件上传到 python API.

I have successfully done uploading of the file to python API.

V1 更新

使用<代码>@已添加->函数(文件) 方法.

这是组件:

<q-uploader
  url=""
  extensions=".gif,.jpg,.jpeg,.png"
  @add="file_selected"
/>

<q-btn @click="uploadFile()">Upload</q-btn>

数据:

data() {
  return {
    selected_file:'',
    check_if_document_upload:false,
  }
}

方法

file_selected(file) {
  this.selected_file = file[0];
  this.check_if_document_upload=true;
},

uploadFile() {
  let fd = new FormData();
  fd.append("file", this.selected_file);

  axios.post('/uploadFile', fd, {
    headers: { 'Content-Type': undefined },
  }).then(function(response) {
    if(response.data.ok) {
    
    }
  }.bind(this));
}

这对我来说很好用.
