动态网站
新建 index.html 内容如下所示
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>首页</title>
</head>
<body>
<form action="./info.html" method="post">
<input type="text" name="userName">
<input type="submit" value="查询">
</form>
</body>
</html>
然后紧接着新建 info.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>用户个人资料</title>
</head>
<body>
<ul>
<li>姓名: !!!name!!!</li>
<li>性别: !!!gender!!!</li>
<li>年龄: !!!age!!!</li>
</ul>
</body>
</html>
然后新建 index.js
let http = require("http");
let path = require("path");
let fs = require("fs");
let url = require("url");
let queryString = require("querystring");
let persons = {
"lisi": {
name: "lisi",
gender: "male",
age: "33"
},
"zhangsan": {
name: "zhangsan",
gender: "female",
age: "18"
}
};
// 1.创建一个服务器实例对象
let server = http.createServer();
// 2.注册请求监听
server.on("request", function (req, res) {
if (req.url.startsWith("/index") && req.method.toLowerCase() === "get") {
let obj = url.parse(req.url);
let filePath = path.join(__dirname, obj.pathname);
fs.readFile(filePath, "utf8", function (err, content) {
if (err) {
res.writeHead(404, {
"Content-Type": "text/plain; charset=utf-8"
});
res.end("Page Not Found");
}
res.writeHead(200, {
"Content-Type": "text/html; charset=utf-8"
});
res.end(content);
});
} else if (req.url.startsWith("/info") && req.method.toLowerCase() === "post") {
let params = "";
req.on("data", function (chunk) {
params += chunk;
});
req.on("end", function () {
let obj = queryString.parse(params);
let per = persons[obj.userName];
let filePath = path.join(__dirname, req.url);
fs.readFile(filePath, "utf8", function (err, content) {
if (err) {
res.writeHead(404, {
"Content-Type": "text/plain; charset=utf-8"
});
res.end("Page Not Found");
}
content = content.replace("!!!name!!!", per.name);
content = content.replace("!!!gender!!!", per.gender);
content = content.replace("!!!age!!!", per.age);
res.end(content);
});
});
}
});
// 3.指定监听的端口
server.listen(3000);
