无法发布错误-node.js-使用multer上传图像

Question

index.html通过单击主页“ localhost：9000 /”上名为“ spons”的链接到达浏览器，URL更改为“ localhost：9000 / spons”，现在当我对表单进行细分时，它会转到URL “ localhost：9000 / spons / uploads”并给出“ cannot POST / spons / uploads”，images文件夹与server.js文件位于同一目录，请您帮我解决这个问题并提出解决方案？

这是index.html文件

 <form name='uploadform' enctype='multipart/form-data' method='post' action='/spons/uploads'> <input name='imageupload' type='file'> <input type="submit" value="Upload Image" name="submit"> </form> 

这是server.js文件

 var express = require('express'); var multer= require('multer'); var upload= multer({dest:'/images'}).single('imageupload'); var router = express.Router(); router.post('/spons/uploads', upload, function(req,res){ res.end('uploaded'); } ); express().listen(9000); 

Answer 1

您cannot POST /spons/uploads ，因为您没有将router附加到应用程序。

var express = require('express');
var app = express();
var multer= require('multer');

var upload= multer({dest:'/images'}).single('imageupload');

var router = express.Router();
router.post('/spons/uploads', upload, function(req,res){
   res.end('uploaded');
});

app.use('/',router); // this line is the key. 

app.listen(9000);

希望能有所帮助。

Answer 2

您甚至不需要显式路由器，请检查以下示例

var express = require('express');
var app = express();
var multer= require('multer');

var upload= multer({dest:'/images'}).single('imageupload');

app.post('/spons/uploads', upload, function(req,res){
   res.end('uploaded');
});

app.listen(9000);
