app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
/// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
/// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
6）package.json 是依赖包管理
{
"name": "file-server",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node ./bin/www"
},
"dependencies": {
"express": "~4.2.0",
"static-favicon": "~1.0.0",
"morgan": "~1.0.0",
"cookie-parser": "~1.0.1",
"body-parser": "~1.0.0",
"debug": "~0.7.4",
"jade": "~1.3.0",
"formidable":"*"
}
}
项目用到了expressjs框架。
3、简单写一个html上传页面
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>upload</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link type="text/css" href="https://www.linuxidc.com/styles.css">
-->
</head>
<body>
<form action="http://localhost/upload" method="post" enctype="multipart/form-data">
<input type="file">
<p>
<input type="submit" value="上传">
</form>
</body>
</html>
4、启动node服务器和Nginx服务器
进入项目根目录，执行 node bin\www 或 npm start (这个是在package.json中配置的脚本命令"scripts")
5、测试
1）上传图片
2）上传成功
3）直接访问image_url就可以看到图片了
