Step 1: Create an Upload Form Create a Node.js file that writes an HTML form, with an upload field: ExampleGet your own Node.js Server This code will produce an HTML form: varhttp = require('http'); http.createServer(function(req, res) { ...
如果任何文件上传到这个模式,将发生 "LIMIT_UNEXPECTED_FILE" 错误。这和 upload.fields([]) 的效果一样。*/app.post('/upload/:type', upload.single('file'), (req, res) =>{ let rt= new pojo.ResultData([req.fileCode, req.fileMsg, req.file]); res.send(rt) }) 二、一些问题 nodejs exp...
chunks.push(file.slice(i, i + size)) } return chunks } 1. 2. 3. 4. 5. 6. 7. 循环调用接口上传,并且存储一些信息,当前分片的索引,注意file必须写在最后一个,因为nodejs端的multer会按照顺序去读的,不然读不到参数, 最后通过promise.all 并发发送请求,等待所有请求发送完成,通知后端合并切片。 const...
nodejs-upload-file.js varhttp =require('http');varfs =require('fs');varformidable =require('formidable');// 包含上传表单的html文件varupload_html = fs.readFileSync("upload_file.html");// 将其替换为保存上传文件的位置varupload_path ="/home/arjun/workspace/nodejs/upload_file/"; http.crea...
2、upload.js var express = require('express'); var app = express(); var fs = require("fs"); var bodyParser = require('body-parser'); var multer = require('multer'); //app.use(express.static('public')); //app.
function(req,file,cb){cb(null,file.originalname)// 使用原始文件名保存上传的文件}});constupload...
使用Node.js上传文件是指通过Node.js编写的服务器端代码来实现文件上传功能。Node.js是一个基于Chrome V8引擎的JavaScript运行环境,具有高效、轻量级、事件驱动等特点,非...
var upload = multer({dest:'upload/'}); 1. 替换为: var storage = multer.diskStorage({ //设置上传后文件路径,uploads文件夹需要手动创建!!! destination: function (req, file, cb) { cb(null, './public/uploads') }, //给上传文件重命名,获取添加后缀名 ...
varupload=multer({storage:storage}); 这样设置uploads文件夹作为上传路径时,需要手动在public内创建uploads。若没有uploads文件夹,浏览器报错" Not found No such file or directory, open ..." 这里有人说没有uploads也能自动创建(我的反正是报错了) ...
PORT}`+'/uploads/'+req.file.filename, }); } }); 直接测试我们的接口地址http://localhost:8888/api/upload 返回数据如下: {"fieldname":"file","originalname":"123.xlsx","encoding":"7bit","mimetype":"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet","destination":"uploads/"...
