C++服务器、QT客户端开发，烧录工具,第1张

C++服务器、QT客户端开发，烧录工具

项目参考基于C++实现的聊天室_csdn_wen的博客-CSDN博客_c++聊天室实现。

在此基础上修改了UI界面，增加了加密验证功能，客户端登陆时使用服务器公钥（RSA2048）加密用户名、密码、对称加密密钥（AES256），服务器接收到用户名和密码，用私钥解密，再和数据库对比，校验通过后，后续通信数据使用客户端发送的AES密钥进行对称加密。

注册功能修改为，客户端密码经过SHA256加密后发送给服务器，MySql中存储Sha256加密后的密码，防止通过数据库泄露密码。

烧录功能采用多线程，主线程负责显示UI、显示下载进度，子线程负责烧录，同时向主线程发送当前的烧录进度、结果。

项目地址：https://github.com/canghenzhilei123/downloadtool

一、环境： 客户端：

*** 作系统：windows10

IDE：Qt 5.14.2

编译器：MinGW 32-bit

服务器：

*** 作系统：华为云CentOS 7.6 64bit

数据库：MySql 5.7.36

二、使用方法 客户端使用方法：

1.安装CH341驱动，设备管理器中出现USB-EPP/I2C... CH341A代表安装成功。


2.安装windows版openssl，下载链接：文件分享，直接点击安装

安装完成后目录：include里面是头文件，lib是库文件，本系统需要用到libcrypto.lib

3.修改Qt项目配置，修改.pro文件，增加network，LIBS中配置CH341DLL.LIB路径，配置为实际路径。LIBS增加openssl libcrypto路径，INCLUDEPATH增加openssl头文件路径，修改为实际路径。

QT += core gui network

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

ConFIG += c++14

LIBS += E:/code/downloadtool/downloadtool/CH341DLL.LIB

LIBS += -L$$quote(D:/OpenSSL-Win32/lib) -llibcrypto
INCLUDEPATH += $$quote(D:/OpenSSL-Win32/include)

 4.编译、将config、image、libcrypto-1_1.dll添加到如下目录。

 5.运行，运行成功效果如下图，d出登录窗口。

服务器使用方法：

 1.安装linux版openssl，参考Centos7安装openssl-1.1.1_rdisme-CSDN博客_centos7 安装openssl，我用的版本是1.1.1d

[root@hecs-33591 ~]# openssl version
OpenSSL 1.1.1d  10 Sep 2019
[root@hecs-33591 ~]#

2.安装jsoncpp，安装方法参考：Jsoncpp的安装配置及示例使用_jenie的专栏-CSDN博客_jsoncpp安装

3.安装MySql，安装方法参考Centos7安装MySQL详细步骤_Horizon-CSDN博客_centos7安装mysql的步骤和方法

安装成功后登录如下：

[root@hecs-33591 jsoncpp-master]# mysql -uroot -p

建议安装Navicat Premium或其他客户端管理数据库。建立如下4个表，建表方法自行学习。

4.修改Makefile，加入openssl头文件和库文件路径，加入库文件引用：-I/opt/ssl/include/ -L/opt/ssl/lib/ -lcrypto，加入jsoncpp头文件和库文件路径，加入库文件引用

-I/usr/local/include/jsoncpp -L/usr/local/lib64

OBJS = ./out/main.o ./out/MyTime.o ./out/MySQLConnector.o ./out/UserService.o ./out/Online.o ./out/DataEncoder.o ./out/HeadData.o ./out/DataProcesser.o ./out/base64.o ./out/sha256.o ./out/rsacrypto.o ./out/aescrypto.o

clean:
	rm -rf ./out/*.o main

5.修改MySql配置，IP，用户名，密码，连接哪个数据库。

[root@hecs-33591 config]# ls
mysql_config.h  server_config.h
[root@hecs-33591 config]# vim mysql_config.h
#pragma once
#define HOST "127.0.0.1"
#define USERNAME "root"
#define PASSWORD ""
#define PORT 3306
#define DATAbase "chatroom"

修改服务器IP，端口，最大连接数。

#pragma once
#define HOST "127.0.0.1"
#define PORT 9999
#define MAX_ConNECTIONS 1024

编译环境如下：

[root@hecs-33591 server]# cmake --version
cmake version 3.21.0-rc2

CMake suite maintained and supported by Kitware (kitware.com/cmake).
[root@hecs-33591 server]# g++ -v

6.编译，在main.cpp路径中执行make，编译成功后生成main

[root@hecs-33591 server]# ls

[root@hecs-33591 server]# ls

7.执行./main，执行成功后提示listening...

[root@hecs-33591 server]# ls
config  crypto  Dao  fw  image  main  main.cpp  Makefile  out  ProtocolHead  Service  Util
[root@hecs-33591 server]# ./main
listening...

此时用客户端连接服务器，连接成功，提示如下：

[root@hecs-33591 server]# ./main
