我需要在SFTP服务器上对上传/下载的某些场景进行测试。为此，我使用apacheJMeter插件SSH协议支持。我能够测试单个用户的单个文件上传。我很难使用这个插件来执行诸如单个用户的多个文件上传或多个用户的多文件上传之类的场景。你知道是否有其他插件可以实现这一点或其他方式吗？
自定义采样器代码
import com.jcraft.jsch.*;
import java.io.*;
def jsch = new JSch()
def session = jsch.getSession(${__property(loginUserName)}, ${__property(hostURL)}, ${__property(port)})
session.setConfig("StrictHostKeyChecking", "no")
session.setPassword(${__property(loginUserPassword)})
def sftpSession = session.connect()
def channel = session.openChannel("sftp")
channel.connect();
def channelSftp = (ChannelSftp)channel;
log.info("SFTP Connection with host is acquired" + channelSftp)
channelSftp.cd(${__property(sftpDestinationFolder)});
for(i = 0; i <100; i++){
def f1 = new File(${__property(inputFileLocationOfBigFile)});
channelSftp.put(new java.io.FileInputStream(f1), f1.getName()+i);
}
session.disconnect()
在apache服务器的GUI模式下运行良好，但在linux盒子或无头方式下运行时，会出现以下错误。

关于如何解决这个问题，有什么帮助吗？
您不能通过单个SFTP连接一次传递多个文件，需要对多个文件进行排队。
但是，您可以由单个用户或与不同用户打开多个连接，只需确保正确参数化凭据和文件名/位置即可。
例如：
- 凭据可以使用CSV数据集配置参数化
- 可以使用目录列表配置对文件进行参数化
