3、libmemcached简单測试使用

#include <iostream>
#include <string>
#include <libmemcached/memcached.h>

using namespace std;

int main(int argc, char *argv[])
{
    //connect server
    memcached_st *memc;
    memcached_return rc;
    memcached_server_st *server;
    time_t expiration = 0;
    uint32_t  flags = 0;

    memc = memcached_create(NULL);
    server = memcached_server_list_append(NULL, "localhost", 11211, &rc);
    rc = memcached_server_push(memc, server);
    memcached_server_list_free(server);

    string key = "key";
    string value = "value";
    size_t value_length = value.length();
    size_t key_length = key.length();


    //Save data
    rc = memcached_set(memc, key.c_str(), key.length(), value.c_str(), value.length(), expiration, flags);
    if (rc == MEMCACHED_SUCCESS)
    {
        cout << "Save data:" << value << " sucessful!" << endl;
    }

    //Get data
    char* result = memcached_get(memc, key.c_str(), key_length, &value_length, &flags, &rc);
    if (rc == MEMCACHED_SUCCESS)
    {
        cout << "Get value:" << result << " sucessful!" << endl;
    }

    //Delete data
    rc = memcached_delete(memc, key.c_str(), key_length, expiration);
    if (rc == MEMCACHED_SUCCESS)
    {
        cout << "Delete key:" << key << " sucessful!" << endl;
    }

    //free
    memcached_free(memc);
    return 0;
}
