redis使用（四）：C 同步接口

一.安装hredis

redis的源码，

下载，解压后，默认安装路径是/usr/local ,（也可以修改Makefile中的变量 DESTDIR PREFIX来设置安装路径），make&&make install 安装；

二，测试同步接口

test.c:

#include<stdio.h>
#include<hiredis/hiredis.h>

#define REDIS_SERVER_IP "x.x.x.x"
#define REDIS_SERVER_PORT 6379

const char* command_set = "set teststr testvalue";
const char* command_get = "get teststr";

void print_reply(const char* cmd, const redisReply* reply){
int i = 0;
switch(reply->type){
case REDIS_REPLY_STATUS:
printf("cmd:%s, reply:%s\n", cmd, reply->str);
break;
case REDIS_REPLY_ERROR:
printf("cmd:%s, reply:%s\n", cmd, reply->str);
break;
case REDIS_REPLY_INTEGER:
printf("cmd:%s, reply:%lld\n", cmd,  reply->integer);
break;
case REDIS_REPLY_NIL:
printf("cmd:%s, reply:nil\n", cmd);
break;

case REDIS_REPLY_STRING:
printf("cmd:%s, reply:%s\n", cmd, reply->str);
break;
case REDIS_REPLY_ARRAY:
printf("cmd:%s, reply:\n", cmd);
for(i = 0; i < reply->elements; ++i)
{
print_reply(cmd, reply->element[i]);
}
break;
default:
printf("unknown type:%d \n", reply->type);
break;
}
}
void test(){
redisReply* r = NULL;
redisContext* c = redisConnect("10.3.1.200", 6379);

if(NULL == c || c->err){
redisFree(c);
printf("connect redis server failed ！");
}

//exec set command
r = (redisReply*) redisCommand(c, command_set);

if(NULL==r){
printf("exe c cmd:%s failed !\n", command_set);
}
print_reply(command_set, r);
freeReplyObject(r);

//exec get command
r = (redisReply*) redisCommand(c, command_get);

if(NULL==r){
printf("exe c cmd:%s failed !\n", command_get);
}

print_reply(command_get, r);
freeReplyObject(r);

redisFree(c);
printf("test over\n");

return;
}

int main()
{
test();
return 0;
}

Makefile:

all:test.c
gcc -o test test.c -I/redis_dir/include -L/redis_dir/lib -lhiredis

测试结果：

$ ./test
cmd:set teststr testvalue, reply:OK
cmd:get teststr, reply:testvalue
