如何在Node.js中上传文件?错误:无法POST/上载

问题：

我在我的upload.ejs中点击提交，我得到错误："无法POST/上传">

---

解决方案：

我的问题是架构问题，而不是编码问题。

为了解决这个问题，我改变了项目的结构。

我创建了一个名为"upload.js"的新文件，将路由器代码放入.

我还将"upload.ejs"移到了项目的根目录中。

我更新了我的"app.js"，以考虑到新的路由器文件"upload.js"。

我将表单改为使用"upload.js"。

代码：

上传.js

var express = require("express");
var router = express.Router();
var flash = require("connect-flash");
var firebase = require("firebase");
var multer = require("multer");
var upload = multer({dest:"./public/images/uploads/"});
router.get("/", function(req, res, next){
    res.render("upload");
});
router.post("/", upload.single("image"), function(req, res, next){
    if (req.file){
        console.log("Uploading file...");
        var image = req.file.filename;
    }
    else {
        console.log("No file uploaded");
        var image = "noimage.jpg";
    }
    var post = {
        title: req.body.title,
        section: req.body.section,
        image: image,
    }
    var section = req.body.section.toLowerCase();
    firebase.database().ref("posts/"+section).push(post);
    req.flash("success_msg", "Post Created");
    res.redirect("/upload");

});
module.exports = router;

上传.ejs

<form enctype="multipart/form-data" method="post" action="upload">

router.post("/upload", upload.single("image"), function(req, res, next){
    if (req.file){
        console.log("Uploading file...");
        var image = req.file.filename;
    }
    else {
        console.log("No file uploaded");
        var image = "noimage.jpg";
    }
    var post = {
        title: req.body.title,
        section: req.body.section,
        image: image,
    }
    var postRef = fbRef.child("posts");
    postRef.push().set(post);
    req.flash("success_msg", "Post Created")
    res.redirect("/"+ req.body.section.toLowerCase());
});

multer = require('multer');
app.use(multer({
        dest: './public/uploads/',
        rename: function (fieldname, filename) {
            return filename.replace(/'W+/g, '-').toLowerCase();
        }
}));

router.post("/upload",function(req, res, next){
    console.log(req.file);
});
