redis 收發資料最簡單的例子

首先第一步鏈結redis

rediscontext *context = redisconnect("127.0.0.1", 6379);

if (context->err)

第二和第三步可以不寫

//2、校驗密碼 

char *auth = "test123";

redisreply *reply = (redisreply *)rediscommand(context, "auth %s", auth);

if (null == reply)

freereplyobject(reply);

//3、選擇資料庫 - 不選擇也可

reply = (redisreply *)rediscommand(context, "select %d", 1);

if (null == reply || redis_reply_error == reply->type)

4. 下面就可以收發資料了

//發布訊息  publish 

redisreply* reply = (redisreply *)rediscommand(context, "subscribe %s %s", "spub","hello messge");

//redisreply* reply = (redisreply *)rediscommand(context, "subscribe %s %b", "spub",messge,size); //二進位制資料

if (null == reply)

freereplyobject(reply);

//訂閱訊息  可以訂閱psubscribe 

redisreply* reply = (redisreply *)rediscommand(context, "subscribe %s", "spub");

if (null == reply||reply->type != redis_reply_array)//訂閱成功返回乙個陣列標識

freereplyobject(reply);

//阻塞等待訂閱訊息

while (true)

reply = (redisreply*)_reply;

for (int nindex = 0; nindex < reply->elements; nindex++)

freereplyobject(reply);

std::cout << "***************" << std::endl;

}非訂閱模式

redisreply* reply = (redisreply *)rediscommand(context, "set %s %s", "spub","hello messge");

//redisreply* reply = (redisreply *)rediscommand(context, "set %s %b", "spub",messge,size); //二進位制資料

if (null == reply)

freereplyobject(reply);

redisreply* reply = (redisreply *)rediscommand(context, "get %s", "spub");

if (null == reply)

if (reply->len > 0)

freereplyobject(reply);
