使用以下 Node.js 架构:index.js + server.js + router.js + requestHandlers.js
刚接触 javascript 应用程序编程。Node.js 如何以最基本的方式与 MongoDB 对话?
猫鼬有必要吗?如果是这样,什么是基本实现?
requestHandlers.js:
var querystring = require("querystring"),
fs = require("fs");
function start(response, postData) {
console.log("Request handler 'start' was called.");
var body = '<html>'+
'<head>'+
'<meta http-equiv="Content-Type" '+
'content="text/html; charset=UTF-8" />'+
'</head>'+
'<body>'+
'<form action="/upload" method="post">'+
'<textarea name="text" rows="20" cols="60"></textarea>'+
'<input type="submit" value="Submit text" />'+
'</form>'+
'</body>'+
'</html>';
response.writeHead(200, {"Content-Type": "text/html"});
response.write(body);
response.end();
}
function upload(response, postData) {
console.log("Request handler 'upload' was called.");
response.writeHead(200, {"Content-Type": "text/plain"});
response.write("You've sent the text: "+
querystring.parse(postData).text);
response.end();
}
exports.start = start;
exports.upload = upload;
exports.show = show;
