连接服务器 - TcpClientConnect ​

函数简介 ​

连接到服务器（异步操作，结果通过回调通知）。

接口名称 ​

TcpClientConnect

DLL调用 ​

c
int32_t TcpClientConnect(int64_t instance, int64_t client_handle, const char* host, int32_t port);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
client_handle长整数型客户端句柄
host字符串主机名或IP地址
port整数型端口号

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long client = ola.TcpClientCreate(nullptr, 0, 0);
int ret = ola.TcpClientConnect(client, "127.0.0.1", 9000);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
long client = ola.TcpClientCreate(nullptr, 0, 0);
int ret = ola.TcpClientConnect(client, "127.0.0.1", 9000);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
client = ola.TcpClientCreate(nullptr, 0, 0)
ret = ola.TcpClientConnect(client, "127.0.0.1", 9000)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
long client = ola.TcpClientCreate(nullptr, 0, 0);
int ret = ola.TcpClientConnect(client, "127.0.0.1", 9000);
cpp
var ola = com("OlaPlug.OlaSoft")
var client = ola.TcpClientCreate(nullptr, 0, 0)
var ret = ola.TcpClientConnect(client, "127.0.0.1", 9000)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
client = ola.TcpClientCreate(nullptr, 0, 0)
ret = ola.TcpClientConnect(client, "127.0.0.1", 9000)
text
.局部变量 ola, OLAPlug
ola.创建 ()
client ＝ ola.TcpClientCreate(nullptr, 0, 0)
ret ＝ ola.TcpClientConnect(client, “127.0.0.1“, 9000)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var client = ola.TcpClientCreate(nullptr, 0, 0);
var ret = ola.TcpClientConnect(client, "127.0.0.1", 9000);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
长整数 client = ola.TcpClientCreate(nullptr, 0, 0)
整数 ret = ola.TcpClientConnect(client, "127.0.0.1", 9000)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long client = ola.TcpClientCreate(nullptr, 0, 0);
int ret = ola.TcpClientConnect(client, "127.0.0.1", 9000);

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
long client = TcpClientCreate(instance, nullptr, 0, 0);
TcpClientConnect(instance, client, "127.0.0.1", 9000);
csharp
long instance = CreateCOLAPlugInterFace();
long client = TcpClientCreate(instance, nullptr, 0, 0);
TcpClientConnect(instance, client, "127.0.0.1", 9000);
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
client = TcpClientCreate(instance, nullptr, 0, 0)
TcpClientConnect(instance, client, "127.0.0.1", 9000)

返回值 ​

整数型，1 成功（开始连接，最终结果通过回调通知），0 失败。

注意事项 ​

  • 这是异步操作，函数立即返回
  • 连接结果通过回调函数通知（event_type=0成功，event_type=1失败）
  • 支持IPv4和IPv6地址
  • 支持域名解析
  • 如果已经连接，再次调用会失败
