3.使用方法

3.1 简单的echo服务器案例

• [1] 编译运行server

>> mkdir build && cd build && ./TestServer
[2024-09-14 09:51:12.961] [chenjingyu] [info] [TestServer.cc: 59] pid = 2485
[2024-09-14 09:51:12.961] [chenjingyu] [info] [Acceptor.cc: 24] Acceptor create nonblocking socket [fd = 6]
[2024-09-14 09:51:12.961] [chenjingyu] [info] [EventLoop.cc: 68] EventLoop start looping.
[2024-09-14 09:51:12.961] [chenjingyu] [info] [EventLoop.cc: 68] EventLoop start looping.
[2024-09-14 09:51:12.961] [chenjingyu] [info] [EventLoop.cc: 68] EventLoop start looping.
[2024-09-14 09:51:12.961] [chenjingyu] [info] [EventLoop.cc: 68] EventLoop start looping.

• [2] 命令模拟client

>> nc 127.0.0.1 8080
aadadadad
aadadadad
112121
112121
hello
hello

3.2 TinyWebServer案例

• [1] Win11的WSL安装MySQL：

# 系统环境：Win11的WSL
# 1.安装mysql相关模块
>> sudo apt-get install mysql-server -y
>> sudo apt-get install libmysqlclient-dev -y

• [2] 配置MySQL

# 1.进入mysql
>> sudo mysql
# 2.进入mysql数据库
mysql> use mysql;
# 3.修改root用户密码
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
# 4.修改远程访问
mysql> UPDATE user SET `Host` = '%' WHERE `User` = 'root' LIMIT 1;
mysql> flush privileges;
mysql> exit;
# 5.创建数据库
mysql> create database webdb;
# 6.给创建的数据库创建表
mysql> use webdb;
mysql> create table user(
  username char(50) NULL,
  passwd char(50) NULL
) engine=InnoDB;
# 7.创建用户
mysql> create user 'mirror'@'localhost' identified by 'cjy';
# 8.给用户mirror表访问权限
mysql> grant all on webdb.user to 'mirror'@'localhost';
# 9.刷新系统权限，即时生效
mysql> flush privileges;

• [3] 修改test/TestHttpServer.cc文件：

server.InitDatabase("localhost", "mirror", "cjy", "webdb", 3306, 8);

• [4] 编译运行HttpServer

>> mkdir build && cd build && ./TestHttpServer
