如何在node.js中上传图像文件？

如何解决如何在node.js中上传图像文件？

 var title="this is title";
  var content="this is content";
  const config = { headers: {'Accept': 'application/json','Content-Type': 'multipart/form-data' } };
  const form = new FormData()
  let file =event.target.files[0]
  form.append('file',file)
 form.append('title',title)
   form.append('content',content)`enter code here`
Axios.post("http://localhost:3001/article/get/123",form,config ).then((res)=>{
     console.log(res.data)
   })

解决方法

在节点中，我已使用multer上传图片或其他任何内容。

下面是我用作中间件的上传代码。

const util = require("util");
const path = require("path");
const multer = require("multer");

const storage = multer.diskStorage({ 
    destination: function (req,file,cb) {
        cb(null,"./Uploads") // folder path where to upload
    },filename: function (req,cb) { 
      cb(null,file.originalname + "-" + Date.now() + path.extname(file.originalname))
    } 
  });

const maxSize = 1 * 20000 * 20000; // file size validation

const uploadFiles = multer({ storage: storage,limits: { fileSize: maxSize } }).array("myfiles",10); // key name should be myfiles in postman while upload

const uploadFilesMiddleware = util.promisify(uploadFiles);

module.exports = uploadFilesMiddleware;

下面是我在控制器中创建的用于上传和文件检查的功能。

fileUpload = async (req,res) => {
  try {
        let userCode = req.headers.user_code;
        await upload(req,res);
        if (req.files.length <= 0) {
            return res.status(httpStatusCode.OK).send(responseGenerators({},httpStatusCode.OK,'Kindly select a file to upload..!!',true));
        }
        let response = [];
        for (const element of req.files) {
            let data =  await service.addFileData(element,userCode);
            response.push(data); // for file path to be stored in database
        }
        if (response && response.length > 0) {
            return res.status(httpStatusCode.OK).send(responseGenerators(response,'File uploaded sucessfully..!!',false));
        } else {
            return res.status(httpStatusCode.OK).send(responseGenerators({},'Failed to upload file kindly try later..!!',true));
        }
      } catch (error) {
            logger.warn(`Error while fetch post data. Error: %j %s`,error,error)
            return res.status(httpStatusCode.INTERNAL_SERVER_ERROR).send(responseGenerators({},httpStatusCode.INTERNAL_SERVER_ERROR,'Error while uploading file data',true))
        }
    }

这条路线会这样。

router.post('/upload/file',fileUploadController.fileUpload);

在上传文件时，请确保在邮递员中保持与中间件相同的名字。

上面的代码在react.js中。我想在node.js中执行相同的工作，并且该文件将从公共文件夹中上传。主要问题是如何以前端event.target.files [0]

中的格式上传图像文件
