函数简介
写入 INFO 级别日志到默认日志实例。
接口名称
LogInfoDLL调用
c
int32_t LogInfo(int64_t instance, const char* message);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。 |
| message | 字符串 | 日志消息 |
示例
SDK 调用
cpp
#include "OLAPlugServer.h"
OLAPlugServer ola;
long log = ola.LogCreateInstance();
ola.LogInfo(log, "operation done");csharp
using OLAPlug;
var ola = new OLAPlugServer();
long log = ola.LogCreateInstance();
ola.LogInfo(log, "operation done");python
from OLAPlugServer import OLAPlugServer
ola = OLAPlugServer()
log = ola.LogCreateInstance()
ola.LogInfo(log, "operation done")java
import com.olaplug.OLAPlugServer;
OLAPlugServer ola = new OLAPlugServer();
long log = ola.LogCreateInstance();
ola.LogInfo(log, "operation done");cpp
var ola = com("OlaPlug.OlaSoft")
var log = ola.LogCreateInstance()
ola.LogInfo(log, "operation done");vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
log = ola.LogCreateInstance()
ola.LogInfo(log, "operation done");text
.局部变量 ola, OLAPlug
ola.创建 ()
log = ola.LogCreateInstance()
ola.LogInfo(log, "operation done")aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var log = ola.LogCreateInstance();
ola.LogInfo(log, "operation done");text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
长整数 log = ola.LogCreateInstance()
ola.LogInfo(log, "operation done");cpp
#include "OLAPlugServer.h"
OLAPlugServer ola;
long log = ola.LogCreateInstance();
ola.LogInfo(log, "operation done");原生 DLL 调用
cpp
long instance = CreateCOLAPlugInterFace();
long log = LogCreateInstance(instance);
LogInfo(instance, log, "operation done");csharp
long instance = CreateCOLAPlugInterFace();
long log = LogCreateInstance(instance);
LogInfo(instance, log, "operation done");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()
log = LogCreateInstance(instance)
LogInfo(instance, log, "operation done")返回值
1 成功,0 失败。
注意事项
- INFO 级别用于记录程序的正常运行信息
- 只有当日志级别设置为
OLA_LOG_LEVEL_INFO(2) 或更低时才会输出 - 这是默认的日志级别,适合生产环境使用
- 如果需要指定日志实例,请使用
LogInfoEx - 如果日志系统未初始化,第一次调用时会自动初始化
