基础环境

目标机：ubuntu20开发机：win10、mac 安装

远程开发套件

本机和目标机都需要安装。

参考 vscode 免密登录服务器编辑配置服务器信息，用vscode打开远程电脑的一个目录。

建立c文件

#include <stdio.h>#include <stdlib.h>#include <unistd.h>//系统函数#include <string.h>#include <pthread.h>//多线程库 #include "net_control_client.h" ts_tcp_client s_tcp_client;  static int connect_to_rver(void){while(connect(s_tcp_client.socket_fd, (母亲节母亲的背影图片struct sockaddr *) &(s_tcp_client.rver_socket_addr),sizeof(struct sockaddr)) != 0){//if connect error reconnect after 5 condsperror("connect");printf("***reconnect after 5s***\n");sleep(5);printf("***reconnect...***\n");}printf("***connected***\n");#if 1//test message nd    sleep(1);char test_msg[] = "this is from client";nd(s_tcp_client.socket_fd, test_msg ,sizeof(test_msg),0);#endifreturn 0;} /* * 接收socket数据函数. * client_fd - 客户端连接的socket。 */static int receive_packet(int client_fd){unsigned char buf[tcp_buffer_size];intrecvbytes;while(1){/*接收*/bzero(buf,sizeof(buf)); recvbytes = recv(client_fd,buf,tcp_buffer_size,0);printf("receive %d bytes\n",recvbytes); if (recvbytes <= 0){//receive error or disconnectedperror("recv");/*reconnect to rver*/printf("clo socket id = %d\n", s_tcp_client.socket_fd);clo(s_tcp_client.socket_fd);//关闭通道s_tcp_client.socket_fd = socket(af_inet, sock_stream, 0);if (s_tcp_client.socket_fd == -1){                printf("###socket init error###\n");perror("socket");return -1;}printf("new socket id = %d\n", s_tcp_client.socket_fd);if (connect_to_rver() != 0){printf("###connect_to_rver error###\n");return -1;}}el{//receive success#if 1//testint i;printf("***get:\n");for (i = 0; i < recvbytes; i++){printf("0x%02x  %c\n", *(buf+i), *(buf+i));}#endif}}return 0;}/*tcp clinet nd thread*/int tcp_nd_start(void){    char buf[100];    uint32_t i = 0;    while(1)    {        sleep(5);        memt(buf,0,sizeof(buf));        sprintf(buf,"***nd data:hello world : %d\n",i);        i++;        printf("%s",buf);        nd(s_tcp_client.socket_fd, buf ,strlen(buf),0);    }}/*tcp clinet running function*/int tcp_client_start(void){    pthread_t tcp_nd_thread_id;//返回的线程值printf("***connect to %s:%d....***\n", s_tcp_client.rver_ip,s_tcp_client.rver_port);/*connect to rver*/if (connect_to_rver() != 0){printf("###connect_to_rver error###\n");return -1;}        //create thread for tcp ndpthread_create(&tcp_nd_thread_id, null, (void *)tcp_nd_start, null);receive_packet(s_tcp_client.socket_fd);return 0;} /* * tcp_client initialize function * port_num -  tcp rver port number * rver_ip - tcp rver ip * */int tcp_client_init(unsigned short port_num, char *rver_ip){int res;struct in_addr test_addr;/*initialize variable*/if (port_num > 0){s_tcp_client.rver_port = port_num;}el{printf("###invalid tcp rver port:%d###\n", port_num);return -1;} if (rver_ip == null){printf("###rver_ip cannot be null###\n");return -1;}el{strcpy(s_tcp_client.rver_ip, rver_ip);绥靖主义//record ip}    printf("rver ip is: %s\r\n",s_tcp_client.rver_ip); /*建立socket描述符*/if ((s_tcp_client.socket_fd = socket(af_inet, sock_stream, 0)) == -1){perror("socket");return -1;}printf("socket id = %d\n", s_tcp_client.socket_fd); /* * 填充服务器sockaddr结构 */bzero(&(s_tcp_client.rver_socket_addr), si无憾青春zeof(struct sockaddr_in));//memts_tcp_client.rver_socket_addr.sin_family = af_inet;inet_pton(af_inet, s_tcp_client.rver_ip, &(s_tcp_client.rver_socket_addr.sin_addr.s_addr));//把ip地址转化为用于网络传输的二进制数值s_tcp_client.rver_socket_addr.sin_port= htons(s_tcp_client.rver_port);//将主机字节顺序转为网络字节顺序bzero(&(s_tcp_client.rver_socket_addr.sin_zero), 8); return 0;} int main(int argc, char *argv[]){int i = 0;int res;pthread_t tcp_thread_id;//返回的线程值char tcp_rver_port[256];char tcp_rver_ip[256];    printf("enter main\r\n");if (argc >= 2){if (strcmp(argv[1],"-v") == 0){printf("net_control_client v1.0\n");return 0;}el if (strcmp(argv[1],"-h") == 0){printf("-v for version\n");printf("-h for help\n");printf("tcp_connect <ip> <port>\n");return 0;}el if (strcmp(argv[1], "tcp_connect") == 0){/*tcp demo*/strcpy(tcp_rver_ip, argv[2]);strcpy(tcp_rver_port, argv[3]); /*initialize functions*/res = tcp_client_init((unsigned short)atoi(tcp_rver_port), tcp_rver_ip);//t tcp clinet ttingif (res == -1){printf("###tcp_rver_init error###\n");return -1;} //create thread for tcp communicationpthread_create(&tcp_thread_id, null, (void *)tcp_client_start, null);}el{printf("unknown argument %s\n",argv[1]);return -1;}}    el{        printf("plea input ip and port\r\n");        exit(0);    }while(1){if (i < 100){i++;}el{i = 0;}sleep(1);}exit(0);}

.h文件

#ifndef net_control_clinet_h_#define net_control_clinet_h_ #include <arpa/inet.h> #define tcp_buffer_size1024//max buff of receive buffer for tcp typedef struct{//tcp client classunsigned short  rver_port;char rver_ip[64];int socket_fd;//socketstruct sockaddr_in rver_socket_addr;}ts_tcp_client;  #endif /* net_control_clinet_h_ */

配置编译任务

进入 ‘main.c’文件，然后点击菜单栏 终端->配置默认生成任务，系统会自动建立一个task.json文件，如下

{"version": "2.0.0","tasks": [{"type": "cppbuild","label": "c/c++: gcc 生成活动文件","command": "/usr/bin/gcc","args": ["-fdiagnostics-color=always","-g","${file}","-o","${filedirname}/${filebanamenoextension}","-lpthread"],"options": {"cwd": "${filedirname}"},"problemmatcher": ["$gcc"],"group": {"kind": "build","isdefault": true},"detail": "编译器: /usr/bin/gcc"}]}

task.json 用来告诉vscode 怎么去编译源文件main.c

lablel 定义该任务的名称，后续调试会根据该名称调用本任务，这里名为c/c++: gcc 生成活动文args ：编译时的参数，比如假设程序依赖 pthread库，，那么在这里指定，这里和手动在命令行输入 gcc xxx 命令相同cwd：指定当前运行路径配置调试程序

仍然保证编辑区打开的是main.c文件，然后点击菜单栏 运行->添加配置，系统会自动建立一个launch.json文件，如下

{    // 使用 intellin 了解相关属性。     // 悬停以查看现有属性的描述。    // 欲了解更多信息，请访问: /d/file/titlepic/debugging#_launch-configurations    "version": "0.2.0",    "configurations": [        {            "name": "gcc - 生成和调试活动文件",            "type": "cppdbg",            "request": "launch",            "program": "${filedirname}/${filebanamenoextension}",            "args": ["tcp_connect","192.168.1.201","8888"],//调试时传递给程序的命令行参数             "stopatentry": true,//是否停留在main函数            "cwd": "${filedirname}",//调试程序时的工作目录             "environment": [],//环境变量             "externalconsole": fal,//调试时是否显示控制台窗口             "mimode": "gdb",//指定连接的调试器，可以为gdb或lldb             "tupcommands": [            老罗英语    {                    "description": "为 gdb 启用整齐打印",                    "text": "-enable-pretty-printing",                    "ignorefailures": true                }            ],            "prelaunchtask": "c/c++: gcc 生成活动文件",//调试开始前执行的任务，一般为编译程序 对应 tasks.json中的label            "midebuggerpath": "/usr/bin/gdb"        }    ]}

默认内容和我贴出来的略有不同，我增加了一些参数launch.json 文件用来告诉vscode怎么调用gdb去调试，指定了一些参数，prelaunchtask：调试开始前执行的任务，一般为编译程序对应 tasks.json中的labelstopatentry”: true,//是否停留在main函数“args”: [“tcp_connect”,“192.168.1.201”,“8888”],//调试时传递给程序的命令行参数比如我调试这个函数需要在命令行输入，也就起跑线上是标准输入输入一些参数，那么填在这里
