编写监控软件程序涉及多个步骤,包括系统信息捕获、数据采集、数据存储、界面设计、屏幕截图、键盘输入监控等。以下是一些关键步骤和示例代码:
1. 系统信息捕获
使用Python的psutil库
```python
import psutil
import time
def monitor_system_info():
while True:
cpu_usage = psutil.cpu_percent()
memory_usage = psutil.virtual_memory().percent
disk_usage = psutil.disk_usage('/').percent
network_connections = len(psutil.net_connections())
print("CPU使用率:", cpu_usage)
print("内存使用率:", memory_usage)
print("磁盘使用率:", disk_usage)
print("网络连接数:", network_connections)
time.sleep(5) 每5秒更新一次
monitor_system_info()
```
2. 数据采集与存储
使用Go语言
```go
package main
import (
"fmt"
"runtime"
"os"
)
func main() {
fmt.Println("OS:", runtime.GOOS)
fmt.Println("CPU cores:", runtime.NumCPU())
mem := runtime.MemStats{}
runtime.ReadMemStats(&mem)
fmt.Printf("Memory used: %v bytes\n", mem.Alloc)
// 将数据写入文件
file, err := os.Create("system_info.txt")
if err != nil {
fmt.Println("Error creating file:", err)
return
}
defer file.Close()
data := fmt.Sprintf("CPU load: %d%%, Memory usage: %d%%", cpu_usage, memory_usage)
_, err = file.WriteString(data)
if err != nil {
fmt.Println("Error writing to file:", err)
}
}
```
3. 界面设计与布局
使用C的Windows窗体应用程序
```csharp
using System;
using System.Drawing;
using System.Windows.Forms;
public class MonitorForm : Form
{
private Button btnStart;
private TextBox txtLog;
public MonitorForm()
{
btnStart = new Button();
btnStart.Text = "开始监控";
btnStart.Click += BtnStart_Click;
txtLog = new TextBox();
txtLog.Multiline = true;
txtLog.ScrollBars = ScrollBars.Vertical;
this.Controls.Add(btnStart);
this.Controls.Add(txtLog);
this.ClientSize = new Size(400, 300);
this.Text = "系统监控软件";
}
private void BtnStart_Click(object sender, EventArgs e)
{
// 开始监控逻辑
}
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MonitorForm());
}
}
```
4. 屏幕截图与监控功能
使用C的System.Drawing命名空间
```csharp
using System;
using System.Drawing;
public class ScreenCapture
{
public static Bitmap CaptureScreen()
{
Bitmap screenshot = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
Graphics gfx = Graphics.FromImage(screenshot);
gfx.CopyFromScreen(0, 0, 0, 0, screenshot.Size);
return screenshot;
}
}
```
5. 远程屏幕监视
使用Java的java.awt.Robot类
