深入解析：Win+VsCode关于C++项目改造成http服务

具体的MSYS2及vscode关于C++任务的调整，参考上一篇博客：

https://blog.csdn.net/weixin_41212298/article/details/154026060

本工程是在windows系统上进行设置的。

1.基本的 C++ 项目结构

my_project/

├── bin/

├── src/

│ └── main.cpp

├── include/

├── .vscode/

│ ├── tasks.json

│ ├── launch.json

│ └── c_cpp_properties.json

└── Makefile (或 CMakeLists.txt)

如：

2.编写示例代码

由于本人启用的windows环境，因此采用纯净版服务

2.1 src/main.cpp:

#define _WIN32_WINNT 0x0A00

#define WIN32_LEAN_AND_MEAN

#include <iostream>

#include <vector>

#include <thread>

#include <mutex>

#include <map>

#include <string>

#include <sstream>

#include <winsock2.h>

#include <ws2tcpip.h>

#pragma comment(lib, "ws2_32.lib")

using namespace std;

class MathService {

public:

static int add(int a, int b) { return a + b; }

static int multiply(int a, int b) { return a * b; }

static vector<int> fibonacci(int n) {

vector<int> result;

if (n <= 0) return result;

result.push_back(0);

if (n == 1) return result;

result.push_back(1);

for (int i = 2; i < n; i++) {

result.push_back(result[i-1] + result[i-2]);

}

return result;

}

};

string create_response(const string& content, const string& content_type = "application/json") {

stringstream response;

response << "HTTP/1.1 200 OK\r\n"

<< "Content-Type: " << content_type << "\r\n"

<< "Content-Length: " << content.length() << "\r\n"

<< "Connection: close\r\n"

<< "Access-Control-Allow-Origin: *\r\n"

<< "\r\n"

<< content;

return response.str();

}

string handle_request(const string& request) {

if (request.find("GET /health") != string::npos) {

return create_response(R"({"status": "healthy", "service": "Windows Socket Server"})");

}

else if (request.find("GET /api/add") != string::npos) {

int a = 15, b = 25;

int result = MathService::add(a, b);

return create_response(R"({"operation": "add", "a": )" + to_string(a) +

R"(, "b": )" + to_string(b) +

R"(, "result": )" + to_string(result) + "}");

}

else if (request.find("GET /api/multiply") != string::npos) {

int a = 8, b = 7;

int result = MathService::multiply(a, b);

return create_response(R"({"operation": "multiply", "a": )" + to_string(a) +

R"(, "b": )" + to_string(b) +
