Question

问题：

我点击了upload.ejs中的提交，我收到错误：“无法发布/上传”

SOLUTION：

我的问题是建筑问题而不是编码问题。

我改变了项目的结构来解决问题。

我创建了一个名为“upload.js”的新文件，用于放入路由器代码。

我还将“upload.ejs”移动到项目的根目录。

我更新了我的“app.js”以考虑新的路由器文件“upload.js”。

我将表单更改为使用“upload.js”。

CODE：

upload.js

{'total_count': '8902', 
'total_pages': 179, 
'page': 1, # This is what I want to change
'results_per_page': 50, 
'data': [
    {'id': '7895426', 
        'team': '123456', 
        '_subtype': 'Standard Survey', 
        ... }, 
    {'id': '7895427', 
        'team': '123456', 
        '_subtype': 'Standard Survey', 
        ... },
    ...]}

upload.ejs

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;

您正在向/upload网址发帖，但您注册的路线是POST /users/upload。可能你必须将follwing函数移动到routes / index.js文件中：

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());

});

您需要使用multer模块：

server.js

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

upload.js

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

如何在Node.js中上传文件？错误：无法POST /上传
