概述
后端上传图片一般把图片存入文件夹中,然后把图片的链接写入数据库,前端访问时后端返回数据库中图片的链接
开始操作
var multer = require('multer'); var upload = multer({dest: '../public/upload_tmp/'}); router.post('/upload', upload.any(), function (req, res) { // console.log(req); // 上传的文件信息 let name = (new Date()).getTime() var des_file = '../public/idCardImage/' + req.files[0].originalname; console.log(req.files[0].originalname) fs.readFile(req.files[0].path, function (err, data) { fs.writeFile(des_file, data, function (err) { if (err) { console.log(err); } else { let response = { message: '图片上传成功', filename: req.files[0].originalname }; // console.log(response); res.json(response) } }); }); })
