示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int ret = ola.GetUnreadAnnouncements("value", "value", "value", "value");
csharp
using OLAPlug;

var ola = new OLAPlugServer();
int ret = ola.GetUnreadAnnouncements("value", "value", "value", "value");
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
ret = ola.GetUnreadAnnouncements("value", "value", "value", "value")
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
int ret = ola.GetUnreadAnnouncements("value", "value", "value", "value");
cpp
var ola = com("OlaPlug.OlaSoft")
var ret = ola.GetUnreadAnnouncements("value", "value", "value", "value")
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ret = ola.GetUnreadAnnouncements("value", "value", "value", "value")
text
.局部变量 ola, OLAPlug
ola.创建 ()
ret ＝ ola.GetUnreadAnnouncements(“value”, “value”, “value”, “value”)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var ret = ola.GetUnreadAnnouncements("value", "value", "value", "value");
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
整数 ret = ola.GetUnreadAnnouncements("value", "value", "value", "value")
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
int32_t ret = ola.GetUnreadAnnouncements("value", "value", "value", "value");

原生 DLL 调用 ​

cpp
long ptr = GetUnreadAnnouncements(instance, "value", "value", "value", "value");
if (ptr != 0) {
    char buffer[512] = {0};
    GetStringFromPtr(ptr, buffer, sizeof(buffer));
    FreeStringPtr(ptr);
}
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringFromPtr(long ptr, StringBuilder lpString, int size);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int FreeStringPtr(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringSize(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long GetUnreadAnnouncements(string userCode, string softCode, string softVersion, string dealerCode);

long ptr = GetUnreadAnnouncements(instance, "value", "value", "value", "value");
if (ptr != 0) {
    StringBuilder sb = new StringBuilder(GetStringSize(ptr) + 1);
    GetStringFromPtr(ptr, sb, sb.Capacity);
    FreeStringPtr(ptr);
    string result = sb.ToString();
}
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
ptr = ola.GetUnreadAnnouncements(instance, "value", "value", "value", "value")
if ptr:
    buf = create_string_buffer(512)
    ola.GetStringFromPtr(ptr, buf, 512)
    ola.FreeStringPtr(ptr)
    result = buf.value.decode("utf-8")

返回值 ​

成功返回 JSON 字符串格式的公告结果；失败返回 0。

注意事项 ​

  • 返回的字符串指针需要调用 FreeStringPtr 接口释放内存。
