从jmeter发布请求中提取值 [英] Extracting value from jmeter post request

问题描述

我想提取通过jmeter中的post请求发送的参数值. 我知道使用正则表达式来提取响应值或请求URL，但在这里我想提取后请求的值.

I want to extract value of the parameter sent through post request in jmeter. I know the use of regular expression for extracting response value or request URL but here I would like to extract the value of post request.

我已经很详尽地如何从Jmeter中的请求中提取值，但是没有用.

I've been thorough how to extract value from request in Jmeter but it didn't worked.

推荐答案

我在带有以下代码的http请求中添加了一个Beanshell PostProcessor.

I added a Beanshell PostProcessor in my http request with following code.

import org.apache.jmeter.config.Argument;
import org.apache.jmeter.config.Arguments;

Arguments argz = ctx.getCurrentSampler().getArguments();
for (int i = 0; i < argz.getArgumentCount(); i++) {
   Argument arg = argz.getArgument(i);
    String a = arg.getValue();
    vars.put("EMAIL",a);
 }    

说明:我将我的请求作为json并将其放在EMAIL中.现在，我可以在其他请求中将EMAIL用作变量.

Explanation: I get a my request as a json and put it in EMAIL. Now I can use EMAIL as a variable in my other request.

然后，我添加了一个jp @ gc Json路径提取器，并将其应用于Jmeter变量. 现在，电子邮件将用作变量，其中包含我的json请求，并且可以使用jsonPath Extractor进行提取.

Then, I added a jp@gc Json Path Extractor and I applied it to a Jmeter Varaible. Now, Email will be used as variable, which contains my json request and I can extract using jsonPath Extractor.
