在jmeter中通过beanshell执行shell命令

Question

在jmeter中通过beanshell执行shell命令。我想在jmeter

中的beanshell预处理器中执行shell命令

任何人都可以告诉你如何这样做。

Answer 1

Beanshell是JAVA（脚本语言）。 下面的陈述应该有所帮助。

Runtime.getRuntime().exec("COMMAND");

Answer 2

基于@vins的回答，我创建了ping测试，以验证我的电子邮件服务器是否可用。

此外，如果您想记录Runttime.getRuntime().exec("COMMAND");的输出，请在您的jmeter BeanShell Sampler中使用与此类似的内容：

// ********
// Ping the email server to verify it's accessable from the execution server
//
// Preconditions:
// custom variable is available named "emailServer" which contains the IP-Adress of the machine to ping
//
// ********

log.info(Thread.currentThread().getName()+": "+SampleLabel+": Ping email server: " + vars.get("emailServer"));

// Select the ping command depending on your machine type windows or unix machine. 
//String command = "ping -n 2 " + vars.get("emailServer");    // for windows
String command = "ping -c2 " + vars.get("emailServer");    // for unix

// Print the generated ping command
log.info(command);

// Create a process object and let this object execute the ping command
Process p = Runtime.getRuntime().exec(command);
p.waitFor();

log.info("Execution complete.");

// Read the output of the ping command and log it
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
StringBuilder logCommandOutput = new StringBuilder();
String line;
while( (line = in.readLine()) != null) {
  logCommandOutput.append(line);
}
in.close();
log.info("Output: " + logCommandOutput.toString());
