关于windows脚本的一些东西

server/2024/9/24 16:29:32/

我前几天碰到一个需求，需要在代码中实现将远程服务器中的文件拷贝到本地，在linux中很好实现，通过sshpass来实现用户名和密码的输入，并且通过scp来拷贝文件

sshpass -p hcsci123456 scp hcsci@192.168.50.50:~/GL01master.log ./

但是在windows环境下是不能执行sshpass的，于是我用到了pscp工具，在powershell中执行

pscp -pw ${password} -r ${username}@${remoteHost}:${remotePath} ${localPath}

将它整合为一个脚本文件就是

param([string]$localPath = "E:/test/" ,[string]$remoteHost
)$username = "hcsci"
$password = "1"
$remotePath = "/home/hcsci/TC384/base_map"$command = "pscp -pw ${password} -r ${username}@${remoteHost}:${remotePath} ${localPath}"
Invoke-Expression $command

在代码中调用这个脚本即可，demo如下：

//获取测试底图
bool PCRLightAccuracyWidget::getTestPhoto(const QString &path)
{//删除base_map文件夹QString deletePath = path + "/base_map";QDir dir(deletePath);if(dir.exists()){if(dir.removeRecursively()){qDebug() << "删除文件成功！" << deletePath;}else{qDebug() << "删除文件失败：" << deletePath;return false;}}else{qDebug() << "base_map不存在，不进行删除";}QProcess process;connect(&process, &QProcess::readyReadStandardOutput, this, [=](){QProcess *process = qobject_cast<QProcess *>(sender());if (process) {QString output = process->readAllStandardOutput();qDebug() << "Output:" << output;}});connect(&process, &QProcess::readyReadStandardError, this, [=](){QProcess *process = qobject_cast<QProcess *>(sender());if (process) {QString errorOutput = process->readAllStandardError();qDebug() << "Error Output:" << errorOutput;}});// 脚本路径QString scriptPath = QCoreApplication::applicationDirPath() + "/CopyFiles.ps1";// 准备参数QString ip;if(m_id == ENUM_CLASS::PCR_Id::M1){ip = "192.168.137.101";}else{ip = "192.168.137.102";}QStringList arguments;arguments << "-ExecutionPolicy" << "Bypass" << "-File" << scriptPath << path << ip;// 调用 PowerShell 执行脚本process.start("powershell", arguments);// 等待命令执行结束if(!process.waitForFinished(-1)){qDebug() << "执行获取测试底图脚本失败:" << process.errorString();return false;}QString output = process.readAllStandardOutput();QString errorOutput = process.readAllStandardError();qDebug() << "Output:" << output;if(!errorOutput.isEmpty()){qDebug() << "Error Output:" << errorOutput;return false;}return true;
}

但是在连接远程主机时，有时候会遇到一些问题，如：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the ECDSA key sent by the remote host is SHA256:ruFzQrEzCAM+pmhyMANEyVCJAKry4tqvkoMHcNzWhk8. Please contact your system administrator. Add correct host key in C:\\Users\\HCSCI/.ssh/known_hosts to get rid of this message. Offending ECDSA key in C:\\Users\\HCSCI/.ssh/known_hosts:1 ECDSA host key for 192.168.137.101 has changed and you have requested strict checking. Host key verification failed.

解决方式如下：

1、known_hosts 文件中删除与 IP 地址 192.168.137.101 相关的密钥
