c连接redis
1. 安装启动redis
2. 安装redis c语言客户端
#include <stdio.h> #include <stdlib.h> #include <hiredis.h> int main(int argc, char **argv) { // if (argc < 3) { // printf("usage: connRedis hostname port password\n"); // return 1; // } // char *hostname = argv[1]; // int port = atoi(argv[2]); // char *password = argv[3]; char *hostname = "127.0.0.1"; int port = 6379; char *password = ""; redisContext *conn; redisReply *reply; struct timeval timeout = {1, 500000}; conn = redisConnectWithTimeout(hostname, port, timeout); // conn erro if (conn == NULL || conn->err) { if (conn) { printf("connection error %s\n", conn->errstr); exit(1); } else { printf("cannot alloc redis context\n"); exit(1); } } // auth reply = redisCommand(conn, "AUTH %s", password); printf("auth is %s\n", reply->str); freeReplyObject(reply); // set reply = redisCommand(conn, "set %s %s", "name", "hello world"); printf("set is %s\n", reply->str); freeReplyObject(reply); // get reply = redisCommand(conn, "get name"); printf("name :%s\n", reply->str); freeReplyObject(reply); // free conn redisFree(conn); return 0; }
编译: gcc connRedis.c -o connRedis -I /usr/local/include/hiredis -lhiredis
这里用clion + cmake编译,运行。需要在CMakeList.txt中添加动态库hiredis
link_libraries(hiredis) add_executable(connRedis.c connRedis)
注意,link要放前面
