之前写过一些文章讲了Groovy如何在JMeter中协助测试：
- 用Groovy处理JMeter断言和日志
- 用Groovy处理JMeter变量
- 用Groovy在JMeter中执行命令行
- 用Groovy处理JMeter中的请求参数
下面分享一下Groovy如何在JMeter文件操作，我选了一个保存超时请求和响应的脚本，抛砖引玉，各位可以依需拓展。如果将这个功能在拓展一些，比如分别记录某些响应错误的请求，超时请求，以及根据业务码不同分别记录请求和响应，对于BUG的追溯将会有很大的帮助。亦可以在请求中进行时间控制，对于某些查询结果响应时间较长的请求，尝试修改类似pageSize的参数，或者请求分页列表，page递增，遇到没有内容的就回头从page=1继续开始等等。
- 首先新建一个简单的线程组和一个简单的请求：
- 添加JSR223 后置处理程序
脚本内容：
代码语言：javascript复制def file = new File("fan.log")
if (!file.exists()) file.createNewFile()
log.info("工作目录地址:" file.getAbsoluteFile())
def end_time = prev.getEndTime()
def start_time = prev.getStartTime()
def response = prev.getResponseDataAsString()
if(end_time - start_time > 100)
file << "FunTester${System.currentTimeMillis()} 参数${sampler.getArguments()} 响应${response}n"
log.info("响应时间${end_time - start_time}")
file.eachLine{
log.info("文件内容:${it}")
}
- 控制台输出：
