Redis接口的调用

1、hiredis是redis数据库的C接口，目录为/redis-3.2.6/deps/hiredis 2、示例代码如下： #include <stdio.h> #include <stdlib.h> #include <stddef.h> #include <stdarg.h> #include <string.h> #include <assert.h> #include "hiredis.h" int main() { //连接redis redisContext* c = redisConnect("127.0.0.1", 6379); if ( c->err) { redisFree(c); printf("Connect to redisServer faile\n"); return -1; } printf("Connect to redisServer Success\n"); const char* setCommand = "set name andy"; redisReply* r = (redisReply*)redisCommand(c, setCommand); if( NULL == r) { printf("Execut setCommand failure\n"); redisFree(c); return -1; } if( !(r->type == REDIS_REPLY_STATUS && strcasecmp(r->str,"OK")==0)) { printf("Failed to execute command[%s]\n",setCommand); freeReplyObject(r); redisFree(c); return -1; } freeReplyObject(r); printf("Succeed to execute command[%s]\n", setCommand); const char* getCommand = "get name"; r = (redisReply*)redisCommand(c, getCommand); if ( r->type != REDIS_REPLY_STRING) { printf("Failed to execute command[%s]\n",getCommand); freeReplyObject(r); redisFree(c); return -1; } printf("Succeed to execute command[%s]\n", getCommand); printf("The value of 'name' is %s\n", r->str); freeReplyObject(r); redisFree(c); return 0; } 3、编译，运行如下： [root@localhost hiredis]# g++ -o main main.cpp libhiredis.a [root@localhost hiredis]# ./main Connect to redisServer Success Succeed to execute command[set name andy] Succeed to execute command[get name] The value of 'name' is andy
