QT聊天项目DAY07

1.Win配置和使用GRPC

1.1 克隆GRPC库

克隆GRPC

git clone -b v1.34.0 https://gitee.com/mirrors/grpc-framework.git

查看Git有没有安装

没有安装

1.1.1 安装Git

https://git-scm.com/

一路next

添加Git的路径到系统环境变量下

我这次没用管理员权限，并且也没有创建grpc文件夹，直接调用下面这个git指令

git clone -b v1.34.0 https://gitee.com/mirrors/grpc-framework.git grpc

1.1.2 修改.gitmodules文件

全部修改成.Gitee上面的

[submodule "third_party/zlib"]path = third_party/zlib#url = https://github.com/madler/zliburl = https://gitee.com/mirrors/zlib.git# When using CMake to build, the zlib submodule ends up with a# generated file that makes Git consider the submodule dirty.

拉取grpc的所有依赖

git submodule update --init

1.1.3 下载CMake

去恋恋风辰老师的网盘下载cmake

https://pan.baidu.com/s/1Yg9Usdc3T-CYhyr9GiePCw?pwd=ng6x

1.1.4 下载nasm 2.16.01

由于nasm网站打不开，自己也编译不了，索性直接用恋恋风辰老师编译好的

2. 从网盘获取编译好的GRPC

https://pan.baidu.com/s/1BBaAZ8-R-GSxxcy2s7TRWA?pwd=ybno

3. 配置编译好的GRPC环境

我不使用属性管理器，直接配，我怕自己忘记怎么配置环境的

编译

D:\BoostNetLib\grpc\visualpro\third_party\abseil-cpp\absl\status\Debug

添加上，在编译，编译成功

4.定义通信协议Protobuf

protobuf的语法版本 为 proto3

定义当前的包名为message

定义一个服务 VerifyService

输入参数类型为 GetVerifyRequest

返回值类型为 GetVarifyRsponse

请求的参数结构为

string email = 1;

返回的参数结构为

错误码 邮箱 和 验证码

也就是这个.proto文件定义了一个基于gRpc的邮箱验证码服务接口，前端调用GetVerifyCode发起验证码请求，后端通过邮箱发出并返回结果，通信数据用Protobuf编码

syntax = "proto3";package message;service VerifyService {rpc GetVerifyCode (GetVerifyRequest) returns (GetVerifyRsponse) {}
}message GetVerifyRequest {string email = 1;
}message GetVerifyRsponse {int32 error = 1;string email = 2;string code = 3;
}

5. 编译通信协议

D:\BoostNetLib\grpc\visualpro\third_party\protobuf\Debug\protoc.exe  -I="." --grpc_out="." --plugin=protoc-gen-grpc="D:\BoostNetLib\grpc\visualpro\Debug\grpc_cpp_plugin.exe" "message.proto"

你们需要更换BoostNetLib

5.2 生成用于序列化和反序列化的文件

D:\BoostNetLib\grpc\visualpro\third_party\protobuf\Debug\protoc.exe --cpp_out=. "message.proto"

5.3 添加到服务器的解决方案中

编译一下，编译成功

6. 创建GRPC通信客户端

当客户端向我们自己写的服务器里发送Post请求时，根据客户端发来的邮箱然后向GRPC服务器去请求

#ifndef VERIFYGRPCCLIENT_H
#define VERIFYGRPCCLIENT_H#include <grpcpp/grpcpp.h>
#include "message.grpc.pb.h"
#include "GlobalHead.h"using grpc::Channel;
using grpc::ClientContext;
using grpc::Status;using message::VerifyService;
using message::GetVerifyRequest;
using message::GetVerifyRsponse;class VerifyGrpcClient : public Singletion<VerifyGrpcClient>
{friend class Singletion<VerifyGrpcClient>;
public:~VerifyGrpcClient();/* 向GRPC服务器请求验证码 */GetVerifyRsponse GetVerifyCode(string email);private:VerifyGrpcClient();unique_ptr<VerifyService::Stub> stub_;
};
#endif // VERIFYGRPCCLIENT_H

#include "VerifyGrpcClient.h"VerifyGrpcClient::VerifyGrpcClient()
{shared_ptr<Channel> channel = grpc::CreateChannel("localhost:50051", grpc::InsecureChannelCredentials());										// 创建GRPC通道stub_ = VerifyService::NewStub(channel);										// 创建Stub
}VerifyGrpcClient::~VerifyGrpcClient()
{}GetVerifyRsponse VerifyGrpcClient::GetVerifyCode(string email)
{ClientContext context;															// GRPC上下文GetVerifyRsponse response;														// 响应对象GetVerifyRequest request;														// 请求对象request.set_email(email);														Status status = stub_->GetVerifyCode(&context, request, &response);				// 发起GRPC请求if (status.ok()){return response;}else{response.set_error(ErrorCodes::RPC_FAILED);return response;}
}

所以在服务器处理客户端post请求中，获取到邮箱后立即向grpc服务器获取验证码

/* 向grpc 服务器获取验证码 */
GetVerifyRsponse verifyRsponse = VerifyGrpcClient::GetInstance()->GetVerifyCode(email);/* 返回响应报文给客户端 */
jsonResonse["error"] = verifyRsponse.error();

编译一下，编译成功

7. 为服务器创建配置文件

{"GateServer": {"Port": 8080},"VerifyServer": {"Port": 50051}
}

创建静态函数库，来解析json

函数实现

#ifndef SERVERSTATIC_H
#define SERVERSTATIC_H#include "GlobalHead.h"class ServerStatic
{
public:/* 解析配置文件 */static int ParseConfig(string configPath, string blockName, string key);
};
#endif // SERVERSTATIC_H

#include "ServerStatic.h"#include <fstream>/* 解析配置文件 */
int ServerStatic::ParseConfig(string configPath, string blockName, string key)
{ifstream file(configPath, ifstream::binary);if (!file.is_open()){cerr << "Failed to open config file: " << configPath << endl;return -1;}Json::Value jsonResult;Json::Reader reader;if (!reader.parse(file, jsonResult)){cout << "Failed to parse config file: " << configPath << endl;return -1;}if (!jsonResult.isMember(blockName)){cout << "Failed to find block: " << blockName << endl;return -1;}return jsonResult[blockName][key].asInt();
}

8. 邮箱验证服务

https://nodejs.org/en

一路安装下去

8.1 初始化Nodejs库的配置

报错

找到生成的包，修改命名

{"name": "VerifyServer","version": "1.0.0","main": "index.js","scripts": {"test": "echo \"Error: no test specified\" && exit 1"},"author": "","license": "ISC","description": ""
}

8.2 安装GRPC-JS库

npm install @grpc/grpc-js

8.3 安装proto库

npm install @grpc/proto-loader

8.4 安装Email处理的库

npm install nodemailer

8.5 将protobuf协议复制到VerifyServer文件夹下

8.6 新建proto.js解析proto文件

加载 message.proto 定义的 gRPC 服务或消息结构，并将其暴露出去供其他文件使用

首先导入库，然后获取当前目录下的message.proto文件，加载.proto文件，保持原始字段名，将int类型当作字符串进行处理，枚举类型也当作字符串处理；

然后将加载好的json对象转换成真正可用的gRpc服务对象

提取message包的内容，把提取到的内容暴露给其他文件使用

const path = require('path')
const grpc = require('@grpc/grpc-js')
const protoLoader = require('@grpc/proto-loader')
const PROTO_PATH = path.join(__dirname, 'message.proto')
const packageDefinition = protoLoader.loadSync(PROTO_PATH, { keepCase: true, longs: String, enums: String, defaults: true, oneofs: true })
const protoDescriptor = grpc.loadPackageDefinition(packageDefinition)
const message_proto = protoDescriptor.message
module.exports = message_proto

最终会被解析成下面这样

const message_proto = {VerifyService: class {constructor(address, credentials, options) { ... }GetVerifyCode(request, callback) {// 发起 gRPC 调用，request 是 { email: 'xxx@example.com' }// callback 是 (err, response) => { ... }}},GetVerifyRequest: class {constructor({ email }) {this.email = email}},GetVerifyRsponse: class {constructor({ error, email, code }) {this.error = errorthis.email = emailthis.code = code}}
}

8.7 开启smtp服务

8.8 读取配置

 8.8.1 新建config.json

8.8.2 新建Global.js

let code_prefix = "code_";const Errors = {Success : 0,RedisErr : 1,Exception : 2,
};module.exports = {code_prefix,Errors}

8.8.3 新建config.js 读取config.json

读取配置文件config.json中的配置信息，并将这些信息导出以供其他模块使用

const fs = require('fs');
let config = JSON.parse(fs.readFileSync('config.json', 'utf8'));
let email_userName = config.email.userName;
let email_passward = config.email.passward;
let mysql_host = config.mysql.host;
let mysql_port = config.mysql.port;
let redis_host = config.redis.host;
let redis_port = config.redis.port;
let redis_passwd = config.redis.passwd;
let code_prefix = "code_";
module.exports = { email_passward, email_userName, mysql_host, mysql_port, redis_host, redis_port, redis_passwd, code_prefix }

8.8.4 新建emial.js

const nodemailer = require('nodemailer');
const config_module = require("./config")
/*** 创建发送邮件的代理*/
let transport = nodemailer.createTransport({host: 'smtp.163.com',port: 465,secure: true,auth: {user: config_module.email_userName,                     // 发送方邮箱地址pass: config_module.email_passward                      // 邮箱授权码或者密码}
});

实现发送邮件的函数

/*** 发送邮件的函数* @param {*} mailOptions_ 发送邮件的参数* @returns */
function SendMail(mailOptions_) {return new Promise(function (resolve, reject) {transport.sendMail(mailOptions_, function (error, info) {if (error) {console.log(error);reject(error);} else {console.log('邮件已成功发送：' + info.response);resolve(info.response)}});})
}
module.exports.SendMail = SendMail

上面全部修改成password，我写错了

8.8.5 新建server.js

gRPC 服务端，提供一个叫 GetVerifyCode 的接口，接收一个邮箱地址，生成验证码并发邮件给这个地址

填写自己的邮箱账号

const grpc = require('@grpc/grpc-js')
const message_proto = require('./proto')
const const_module = require('./global')
const { v4: uuidv4 } = require('uuid');
const emailModule = require('./email');async function GetVerifyCode(call, callback) {console.log("email is ", call.request.email)try {uniqueId = uuidv4();console.log("uniqueId is ", uniqueId)let text_str = '您的验证码为' + uniqueId + '请三分钟内完成注册'//发送邮件let mailOptions = {from: '******@163.com',to: call.request.email,subject: '验证码',text: text_str,};let send_res = await emailModule.SendMail(mailOptions);console.log("send res is ", send_res)callback(null, {email: call.request.email,error: const_module.Errors.Success});} catch (error) {console.log("catch error is ", error)callback(null, {email: call.request.email,error: const_module.Errors.Exception});}
}
function main() {var server = new grpc.Server()server.addService(message_proto.VerifyService.service, { GetVerifyCode: GetVerifyCode })server.bindAsync('0.0.0.0:50051', grpc.ServerCredentials.createInsecure(), () => {server.start()console.log('grpc server started')})
}
main()

Java看不懂，只会c++，这些代码已经脱离我的掌控了，难崩

8.8.6 修改package.json

{"name": "VerifyServer","version": "1.0.0","main": "server.js","scripts": {"serve": "node server.js"},"author": "","license": "ISC","description": "","dependencies": {"@grpc/grpc-js": "^1.13.3","@grpc/proto-loader": "^0.7.15","nodemailer": "^6.10.1"},"devDependencies": {"eslint": "^9.25.1"}
}

8.8.7 卸载MySql并重装

1. 首先查看自己的Mysql的服务名，并停止服务

2. 以管理员权限运行cmd

彻底卸载Mysql的博客

重新安装MySql的博客

https://blog.csdn.net/m0_52559040/article/details/121843945

我的MySql密码  123456

我是因为忘了密码才选择重新安装的

8.8.8 修改config.json

  "mysql": {"host": "localhost","port": 3306,"password": "123456"},"redis": {"host": "81.68.86.146","port": 6380,"passwd": "123456"}
}

9. 测试

9.1 启动GRPC服务器，通过GRPC服务去发送邮件到注册的邮箱里面

9.2 服务器启动

9.3 QT客户端启动

9.4 获取验证码

已证实发送，从结果反推过程

10. 从结果反推过程

10.1 解决乱码问题

首先验证到底是哪里出了问题

查看自己的VS编码形式，不知道在哪里查的看这篇文章

https://blog.csdn.net/qq_41868108/article/details/105750175

改成UTF-8编码试试看

没有问题，所以是编码形式出错了，需要将中文按照utf-8编码

由于对JavaScript的语法不熟悉，放弃尝试，最后获取到的邮件

已解决

10.2 注册验证一条龙

当注册按钮点击时，将Email中的信息和URL都填充进去，然后发送Post请求给服务器，因为URL的格式如下

http://localhost:8080//getVarifycode,所以本地开启服务器后就能够收到客户端发来的请求了

服务端：

在这里是向GRPC服务器发送请求

在JavaScript中启动grpc服务器，监听本机是否有连接

在我们的message_proto中定义了一个名为VerifyService的服务

服务器会监听VerifyService.GetVerifyCode方法，一旦客户端调用这个方法，服务端就会进入实现的GetVerifyCode函数中去处理请求，然后把响应结果通过callback返回

客户端调用这个方法时(GetVerifyCode)会发送一个GetVerifyRequest服务器返回一个GetVerifyResponse，后续就是通过uuid生成为唯一的验证码去返回给c++调用GRPC中的GetVerifyCode的客户端，然后再qt的前端中输入自己qq邮箱中接收到的验证码，跟c++服务器中的验证码对比，就注册成功了
