samples

1. custom log handler

我们可以自定义redis_cpp的内部日志处理函数以及设置内部日志级别, 默认是输出到控制台

#include <iostream>
#include <strstream>
#include <vector>
#include <redis_cpp.hpp>
#include <utility/asio_base/thread_pool.hpp>

//#define __standalone_sync_client_test__
//#define __standalone_sync_client_pool_test__
#define __cluster_sync_client_test__

//#define __standalone_async_client_test__
#define __cluster_async_client_tet__

void custom_log_handler(redis_cpp::internal::rds_log_level log_level, const char* data, int32_t len){
    printf("custom_log_handler, lvl[%d], msg[%s], len[%d]\n", log_level, data, len);
}

static const char* loglvl_str(redis_cpp::internal::rds_log_level lvl){
    static const char* log_level_strs[] = { "debug", "info", "warn", "error", "fatal" };
    static const char* uknow_level = "unknow";
    if (lvl >= redis_cpp::internal::rds_log_level_debug &&
        lvl <= redis_cpp::internal::rds_log_level_fatal){
        return log_level_strs[lvl];
    }
    return uknow_level;
}

void redis_cpp_log_handler_1(redis_cpp::internal::rds_log_level log_level, const char* data, int32_t len){
    auto tp = std::chrono::system_clock::now();
    auto tt = std::chrono::system_clock::to_time_t(tp);
    auto duration = tp.time_since_epoch();
    int32_t millis = std::chrono::duration_cast<std::chrono::milliseconds>(duration).count() % 1000;

    struct tm* ptm = localtime(&tt);
    char date[64] = { 0 };

    sprintf(date, "%d-%02d-%02d %02d:%02d:%02d,%03d",
        (int32_t)ptm->tm_year + 1900, (int32_t)ptm->tm_mon + 1, (int32_t)ptm->tm_mday,
        (int32_t)ptm->tm_hour, (int32_t)ptm->tm_min, (int32_t)ptm->tm_sec, millis);

    printf("--------[%s][%s][rds] %s\n", date, loglvl_str(log_level), data);
}

int main()
{
    std::cout << "redis_cpp test." << std::endl;

	// set the internal loggel level
	redis_cpp::set_log_lvl(redis_cpp::internal::rds_log_level_debug);
	// set the internal log handler
    redis_cpp::set_log_handler(redis_cpp_log_handler_1);

	return 0
}

2. redis stanalone, sentinel, cluster 三种模式下的operator

• 单例模式(standalone)
  • 单链接

    using namespace redis_cpp;
    using namespace redis_cpp::detail;
    
    utility::asio_base::thread_pool pool(2);
    pool.start();
    standalone_sync_client* sync_client = new standalone_sync_client(pool.io_service(), redis_uri.c_str());
    sync_client->connect();
    
    // operator
    redis_sync_operator client(sync_client);
    
    // set foo bar
    client.set("foo", "bar");
    
    // get foo
    std::string res_foo;
    if (client.get("foo", res_foo))
    {
        printf("get foo: %s\n", res_foo.c_str());
    }
    else
    {
        printf("get foo: failed\n");
    }
    

  • 连接池

    using namespace redis_cpp;
    using namespace redis_cpp::detail;
    
    utility::asio_base::thread_pool pool(2);
    pool.start();
    standalone_sync_client_pool client_pool(redis_uri.c_str(), 1, 2, &pool);
    base_sync_client* sync_client = &client_pool;
    
    // operator
    redis_sync_operator client(sync_client);
    
    // set foo bar
    client.set("foo", "bar");
    
    // get foo
    std::string res_foo;
    if (client.get("foo", res_foo))
    {
        printf("get foo: %s\n", res_foo.c_str());
    }
    else
    {
        printf("get foo: failed\n");
    }
    

• 哨兵模式(sentinel)

    using namespace redis_cpp;
    using namespace redis_cpp::detail;
    
    std::string master_name = "test_master";
    const char* srv_list = "127.0.0.1:26379";
    // sentinel client
    sentinel_client_pool_ptr client_pool = sentinel_client_pool::create(srv_list);
    client_pool->start();
    
    std::string redis_uri_str = "redis://foobared@127.0.0.1:6381/1";
    redis_uri uri(redis_uri_str.c_str());
    
    std::pair<std::string, int32_t> address;
    if (client_pool->get_master_address_by_name(master_name.c_str(), address))
    {
        uri.set_ip(address.first.c_str());
        uri.set_port(address.second);
    
        printf("master_name[%s]'s master address is [%s:%d].\n", 
    		master_name.c_str(), address.first.c_str(), address.second);
    
        redis_uri_str = uri.to_string();
    }
    else
    {
        printf("try get master_name[%s]' master address failed.\n", master_name.c_str());
    }
    
    // sentinal sync client
    sentinel_sync_client* client = new sentinel_sync_client("acmaster", redis_uri_str.c_str(), 1, 2);
    client->set_sentinel_client_pool(client_pool);
    redis_sync_operator redis_op(client);
  
    // set foo bar
    client.set("foo", "bar");
    
  

• 集群模式

    using namespace redis_cpp;
    using namespace redis_cpp::detail;
  
    utility::asio_base::thread_pool pool(2);
    pool.start();
    std::string redis_uri_list = "redis://foobared@127.0.0.1:7000;redis://foobared@127.0.0.1:7001;redis://foobared@127.0.0.1:7002";
    cluster_sync_client cluster(redis_uri_list.c_str(), 1, 2);
    base_sync_client* sync_client = &cluster;
    
    // operator
    redis_sync_operator client(sync_client);
  
    // set foo bar
    client.set("foo", "bar");
    
    // get foo
    std::string res_foo;
    if (client.get("foo", res_foo))
    {
        printf("get foo: %s\n", res_foo.c_str());
    }
    else
    {
        printf("get foo: failed\n");
    }
