golang windows下监控进程IO操作-Go服务器开发

要在 Windows 下监控进程的 I/O 操作，可以使用 syscall 包提供的 ReadProcessMemory() 和 WriteProcessMemory() 函数。下面是一个示例代码：

package main

import (
	"fmt"
	"syscall"
	"time"
	"unsafe"

	"golang.org/x/sys/windows"
)

func main() {
	processName := "notepad.exe"
	
	fmt.Println("Waiting for process", processName, "to start...")
	
	var processHandle windows.Handle
	for {
		processId, err := getProcessIdByName(processName)
		
		if err == nil {
			processHandle, err = windows.OpenProcess(windows.PROCESS_ALL_ACCESS, false, uint32(processId))
			
			if err == nil && processHandle != 0 {
				fmt.Println("Successfully opened handle for process", processName)
				break
			}
		}
		
		time.Sleep(time.Second)
	}

	for {
	    var buffer [1024]byte
	    
	    // 监控 ReadProcessMemory()
	    bytesRead := uint32(0)
	    success := windows.ReadProcessMemory(processHandle,
                                             uintptr(unsafe.Pointer(&buffer)),
                                             uintptr(unsafe.Pointer(&buffer[0])),
                                             uintptr(len(buffer)),
                                             &bytesRead)
                                             
        if success && bytesRead > 0 {
            fmt.Printf("[Intercepted] ReadProcessMemory: %s\n", string(buffer[:bytesRead]))
        }
        
        // 监控 WriteProcessMemory()
        bytesWritten := uint32(0)
        success = windows.WriteProcessMemory(processHandle,
                                              uintptr(unsafe.Pointer(&buffer)),
                                              uintptr(unsafe.Pointer(&buffer[0])),
                                              uintptr(len(buffer)),
                                              &bytesWritten)
                                              
        if success && bytesWritten > 0 {
            fmt.Printf("[Intercepted] WriteProcessMemory: %s\n", string(buffer[:bytesWritten]))
        }
        
        time.Sleep(time.Second)
    }
}

// 根据进程名获取进程 ID
func getProcessIdByName(processName string) (int, error) {
	snapshotHandle, err := windows.CreateToolhelp32Snapshot(windows.TH32CS_SNAPPROCESS, 0)
	if err != nil {
		return 0, err
	}
	defer windows.CloseHandle(snapshotHandle)

	var processEntry windows.ProcessEntry32
	processEntry.Size = uint32(unsafe.Sizeof(processEntry))

	err = windows.Process32First(snapshotHandle, &processEntry)
	if err != nil {
		return 0, err
	}

	for {
		if syscall.UTF16ToString(processEntry.ExeFile[:]) == processName {
			return int(processEntry.ProcessID), nil
		}

		err = windows.Process32Next(snapshotHandle, &processEntry)
		if err != nil {
			break
		}
	}

	return 0, fmt.Errorf("process not found")
}

在上面的代码中，我们首先等待指定进程（notepad.exe）启动，然后打开其句柄并开始循环监控 ReadProcessMemory() 和 WriteProcessMemory() 函数。当这些函数被调用时，我们会输出相应的 I/O 操作信息。

需要注意的是，监控其他进程的 I/O 操作可能会有一定的安全风险，请谨慎使用。另外，在使用 ReadProcessMemory() 和 WriteProcessMemory() 函数时，请务必了解其参数和返回值的含义，并进行相关测试和优化。
