Javascript 从节点js中的多个表单字段或多个输入类型上载多个图像

如何上传节点js中不同表单字段的所有图像这里是表单

<form action="/profile" method="post" enctype="multipart/form-data">
  <input type="file" name="img1" />
  <input type="file" name="img2" />
  <input type="file" name="img3" />
</form>

在你需要这个包裹之后

npm i --save multer

您还可以为每种文件类型增加多个图像上载的最大计数

npm i --save multer

const multer  = require('multer')

var cpUpload = upload.fields([{ name: 'img1', maxCount: 1 }, { name: 'img2', maxCount: 1 }, { name: 'img3', maxCount: 1 }])
app.post('/profile', cpUpload, function (req, res, next) {
  // req.files is an object (String -> Array) where fieldname is the key, and the value is array of files
  //
  // e.g.
  //  req.files['img1'][0] -> File
  //  req.files['img2'] -> Array
  //
  // req.body will contain the text fields, if there were any
})
