在Node.js中上传多个文件不包含multer？

如何解决在Node.js中上传多个文件不包含multer？

目前，我可以将其发布到mongodb。很好。

问题 我应该能够发布多个彼此独立的附件，而不是一个附件，这N个上传将有N个不同的按钮。

const form = (req,res,next) => {

  const file = req.files.photo;

  file.name = `photo_${Math.random(0,10012)}-${Math.random(0,2000)}${
    path.parse(file.name).ext
  }`;

  file.mv(`./public/uploads/${file.name}`,async (err) => {
    if (err) {
      console.error(err);
      return res.status(500).json({
        message: `Problem With File Upload`,});
    }
    
    const upload = await Form.create({
       approved: req.body.approved,email_: req.body.email,formData: {
        name: "req.body.formData.claimantName",nationality: "req.body.formData.claimantNationality",address: "req.body.formData.claimantAddress",email: "req.body.formData.claimantEmail",},attachments: [
        {
          powerOfAttorney: file.name,// these are the next 

          // disputeDocuments: req.body.formData.disputeDocuments,// arbitrationAgreement: req.body.formData.arbitrationAgreement,// cvOfArbitrator: req.body.formData.cvOfArbitrator,],});
    return res.status(200).json({
      success: true,message: `File Uploaded Successfully`,path: file.name,});
  });
};

router.route("/add").post(form);

我尝试将const upload = await Form.create(...)移到file.mv(...)块之外并进行类似的操作`'' const file1 = req.files.photo1;

file1.name = photo_${Math.random(0,2000)}${ path.parse(file1.name).ext };

It doesn't work properly.

解决方法

我认为您可以在端点{} {1}}对象中的节点服务器的request对象中获取上载的文件。

您的端点应捕获这样的文件

req.files

由于您将获得键值对的对象，因为const uploads = Object.values(req.files); 将是文件名key将是包含名称等的文件数据对象。value会将那个对象转换为具有上载文件信息的对象数组。之后，创建一个Object.values，它将捕获如下所示的文件：

用于处理文件上传的功能

promise

之后，将上传的内容传递给Promise，并在handleFileUpload = (uploads) => { return new Promise((resolve,reject) => { const dbData = []; uploads.forEach(async (upload) => { const name = await `photo_${Math.random(0,10012)}-${Math.random(0,2000 )}${path.parse(upload.name).ext}`; dbData.push(name); await upload.mv(`your-path/${name}`,async (err) => { if (err) { reject("Something wrong"); } }); }); resolve(dbData); }); }; 块中创建数据库insertion。

then

handleFileUpload(uploads).then((response) => { ... }).catch((e) => { ... }); 将具有所有图像路径。

注意：我正在考虑将文件为response
