node.js - Node Js 检索并显示图像

Question

我能够使用 Node.Js 和 Multer 上传图像。图像以加密格式保存，名称随机。如何检索和显示 .jade 文件或 .hetml 文件中的图像？

//My Code to upload image

router.post("/upload", function(req, res, next){
    if (req.files) { 
        console.log(util.inspect(req.files));
        if (req.files.myFile.size === 0) {
                    return next(new Error("Hey, first would you select a file?"));
        }
        fs.exists(req.files.myFile.path, function(exists) { 
            if(exists) { 
                res.end("Got your file!"); 
            } else { 
                res.end("Well, there is no magic for those who don’t believe in it!"); 
            } 
        }); 
    } 
});


// Upload page (Jade file)

    form#fileUpload(method="post" action="/uploads/upload" enctype="multipart/form-data")
        label(for="payload") Select a file to upload:
        input#fileToUpload(type='file', name='myFile')
        //input#payload(type="file" name="myFile" accept="image/*")
        br
        button#upload Upload

Answer 1

var multer = require('multer'),
upload = multer({dest: 'uploads/'});
app.post('/multipart-upload', upload.single('file'),  function(req, res){
   var filename = req.file.path;
   console.log('Uploading File: ' + JSON.stringify(req.file));
});

Multer 需要一个上传文件的路径。您可以将路径保留在express的public/static文件夹中，并直接链接该文件。

或者您可以使用静态文件中间件来提供上传文件夹中的文件并直接链接它们。

app.use('/image-uploads',express.static('uploads'));
