今天完成的事情：
1，学习用nodejs写一个后台
const http = require('http');
const url = require('url');
const querystring = require('querystring');
const fs = require('fs');
let users = {
blue:123456
};
let server = http.createServer((req, res) => {
//GET
let {
pathname,
query
} = url.parse(req.url, true);
//POST
let str = "";
req.on('data', data => {
str += data;
});
req.on('end', () => {
let post = querystring.parse(str);
console.log(pathname, query, post);
});
let {user,pass} =query;
switch (pathname) {
case '/reg': //注册
if (!user) {
res.write('{"err":1,"msg":"user is required"}');
} else if (!pass) {
res.write('{"err":1,"msg":"pass is required"}');
} else if (!/^\w{8,32}$/.test(user)) {
res.write('{"err":1,"msg":"invalid username"}');
} else if (/^['|"]$/.test(pass)) { // /['|"]/
res.write('{"err":1,"msg":"invalid password"}');
} else if (users[user]) {
res.write('{"err":1,"msg":"username already exists"}');
} else {
users[user] = pass;
res.write('{"err":0,"msg":"success"}');
}
res.end();
break;
case '/login': //登录
if (!user) {
res.write('{"err":1,"msg":"user is required"}');
} else if (!pass) {
res.write('{"err":1,"msg":"pass is required"}');
} else if (!/^\w{8,32}$/.test(user)) {
res.write('{"err":1,"msg":"invalid username"}');
} else if (/^['|"]$/.test(pass)) {
res.write('{"err":1,"msg":"invalid password"}');
} else if (!users[user]) {
res.write('{"err":1,"msg":"no this user"}');
} else if (users[user]!=pass) {
res.write('{"err":1,"msg":"username or password is incorrect"}');
} else {
res.write('{"err":0,"msg":"success"}');
}
res.end();
break;
default: //文件
fs.readFile(`www${pathname}`, (err, data) => {
if (err) {
res.writeHeader(404);
res.write('Not Found');
} else {
res.write(data);
}
res.end();
})
};
});
server.listen(8080);
