在C/C++与Python之间实现通信的常见方法

import subprocess
 
result = subprocess.run(['your_cpp_program'], input='input_data', text=True, capture_output=True)
print(result.stdout)

#include <fstream>
using namespace std;
 
int main() {
    ofstream output("output.txt");
    output << "Hello from C/C++!";
    output.close();
    return 0;
}

with open('output.txt', 'r') as file:
    result = file.read()
    print(result)

// C/C++ TCP Server
#include <iostream>
#include <cstring>
#include <arpa/inet.h>
#include <unistd.h>
 
int main() {
    int serverSocket = socket(AF_INET, SOCK_STREAM, 0);
 
    struct sockaddr_in serverAddress;
    serverAddress.sin_family = AF_INET;
    serverAddress.sin_addr.s_addr = INADDR_ANY;
    serverAddress.sin_port = htons(8888);
 
    bind(serverSocket, (struct sockaddr*)&serverAddress, sizeof(serverAddress));
    listen(serverSocket, 5);
 
    int clientSocket = accept(serverSocket, NULL, NULL);
 
    char buffer[1024] = {0};
    read(clientSocket, buffer, sizeof(buffer));
    std::cout << "Received from Python: " << buffer << std::endl;
 
    close(serverSocket);
    return 0;
}

# Python TCP Client
import socket
 
clientSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
clientSocket.connect(('127.0.0.1', 8888))
 
message = "Hello from Python!"
clientSocket.sendall(message.encode())
 
clientSocket.close()
