Question

我正在开发一个股票图像网站，并面临使用cloudinar和multer将图像上传到cloudinary的问题。 “”添加图片功能有效，但添加个人资料图片功能无效。有人可以帮我这个忙吗？我的代码在下面的屏幕截图中。我正在使用node.js + Express进行开发。非常感谢！

//======================================================================
                            //CLOUDINARY + MULTER SETUP
//======================================================================
var multer = require('multer');
var storage = multer.diskStorage({
  filename: function(req, file, callback) {
    callback(null, Date.now() + file.originalname);
  }
});
var imageFilter = function (req, file, cb) {
    // accept image files only
    if (!file.originalname.match(/\.(jpg|jpeg|png|gif)$/i)) {
        return cb(new Error('Only image files are allowed!'), false);
    }
    cb(null, true);
};
var upload = multer({ storage: storage, fileFilter: imageFilter})

var cloudinary = require('cloudinary');
cloudinary.config({ 
  cloud_name: xxxxxxx ,
  api_key: xxxxxxx, 
  api_secret: 'xxxxxxx
});

下面给出的代码

//CREATING NEW IMAGE
app.post("/images", isLoggedIn, upload.single('image'),function(req, res){


           cloudinary.uploader.upload(req.file.path, function(result) {
          // add cloudinary url for the image to the campground object under image property
        var image=req.body.image;
        image = result.secure_url;
        var title= req.body.title;
            var price=req.body.price;
        var author={
        id: req.user._id,
        username: req.user.username,
        profile_picture: req.user.profile_picture
        };
         var description=req.body.description;

     var newImage = {title: title, image: image, description: description, price: price,author: author};

    Image.create(newImage, function(err, newlyCreated){
        if(err){
            console.log(err);
        }else{
            console.log(newlyCreated);
            res.redirect("/images");
        }
    });
});
});

这就是我要解决的问题

//Adding Profile Picture FORM
app.get("/profile/:id/edit", function(req, res){
    User.findById(req.params.id, function(err, foundUser){
        if(err){
            req.flash("error", "Oops Something went wrong! Try again Later!");
            res.redirect("back");
        }else{
            console.log(foundUser._id);
            res.render("userDisplayPicture", {user: foundUser});
        }
    });

});

app.put("/profile/:id", upload.single('image'), function(req, res){
            cloudinary.uploader.upload(req.file.path, function(result) {
                  // add cloudinary url for the image to the campground object under image property

                var profile_picture = req.body.profile_picture;
                profile_picture = result.secure_url;



            User.findByIdAndUpdate(req.params.id, profile_picture, function(err, foundUser){
                if(err){
                    req.body.flash("error", "Oops! Something went wrong! Try again later!");
                    res.redirect("/profile/"+ req.params.id);
                }
                else{
                    req.body.flash("success", "Profile Picture Updated Successfully!");
                    res.redirect("/profile/"+req.params.id);
                }
            });

        });
});

错误
