进出口新的节点JS现在我想要做的图像upload.so我下载快递框架来处理upload.Please帮助我如何处理在服务器一侧上传。
我创造了这样的形式，如何在后端节点JS处理这
<form method="post" enctype="multipart/form-data" action="/file-upload">
<input type="text" name="username">
<input type="password" name="password">
<input type="file" name="thumbnail">
<input type="submit">
使用上载该方法
app.post('/upload', function(req, res) {
// get the temporary location of the file
var tmp_path = req.files.thumbnail.path;
// set where the file should actually exists - in this case it is in the "images" directory
target_path = '/tmp/' + req.files.thumbnail.name;
// move the file from the temporary location to the intended location
fs.rename(tmp_path, target_path, function(err) {
if (err) throw err;
// delete the temporary file, so that the explicitly set temporary upload dir does not get filled with unwanted files
fs.unlink(tmp_path, function() {
if (err) throw err;
});
});
});
虽然retriving显示了此方法路径
fs.readFile(target_path, "binary", function(error, file) {
if(error) {
res.writeHead(500, {"Content-Type": "text/plain"});
res.write(error + "\n");
res.end();
} else {
res.writeHead(200, {"Content-Type": "image/png"});
res.write(file, "binary");
}
});
请参阅的NodeJS expressjs上传图片并显示它们的详细信息
