将BSF后处理器中使用的变量用作另一个采样器中的参数 [英] Using variables used in BSF post-processor as a parameter in another sampler

问题描述

我在采样器中添加了BSF后处理器.
后处理器中的脚本是:

I have a BSF post-processor added to a sampler.
The script in the post-processor is:

var array = JSON.parse(prev.getResponseDataAsString());

array.forEach(function(object)
{
  OUT.println("patient_id: "+object.patientId);
  OUT.println("fname: "+object.fname);
  OUT.println("lname: "+object.lname);
});

现在我想使用object.patientId，object.fname，object.lname值作为另一个请求的参数中的参数.

now i want to use object.patientId, object.fname, object.lname values as parameters in another request's parameters.

例如

Thread Group
- Sampler1
    BSF Post-Processor
- Sampler2

我要使用Sampler1的BSF Post Processor javascript中的变量作为Sampler2中的参数.有可能吗?

I want to use the variables in the BSF Post Processor's javascript of Sampler1 as parameters in Sampler2. Is that possible?

推荐答案

轻松: BSF PostProcessor 提供对Jmeter变量/属性的读/写访问权限:

Easily: BSF PostProcessor provides read/write access to Jmeter Variables / Properties:

vars-(JMeterVariables)-提供对变量的读/写访问权限: vars.get(key); vars.put(key，val); vars.putObject("OBJ1"，new Object()); vars.getObject("OBJ2");

vars - ( JMeterVariables) - gives read/write access to variables: vars.get(key); vars.put(key,val); vars.putObject("OBJ1",new Object()); vars.getObject("OBJ2");

道具-(JMeterProperties-类java.util.Properties)-例如 props.get("START.HMS"); props.put("PROP1"，"1234");

props - (JMeterProperties - class java.util.Properties) - e.g. props.get("START.HMS"); props.put("PROP1","1234");

在最简单的情况下，您可以使用

In the simplest case you can use

vars.put(patientId,object.patientId.toString());
vars.put(fName,object.fname.toString());
vars.put(lName,object.lname.toString());

在您的BSF PostProcessor中

设置变量，然后获得它们的值，如

in your BSF PostProcessor to set the variables, and then get they values like

vars.get("patientId")

或

${patientId}

但是由于您要立即提取foreach循环中的所有记录，因此无法使用这种方式.

But since you are extracting ALL the records in foreach loop at once you cannot use this way.

在这种情况下，您最好使用类似以下的方法:将在foreach循环中提取的所有记录值写入csv文件，然后使用例如 CSV数据集配置，以循环方式读取记录并使用值连同您的Sampler2:

In this case you have to better use something like the following: write all the records values extracted in foreach loop into csv-file, and then use e.g. CSV Data Set Config to read records one-by-one in loop and use values along with your Sampler2:

While Controller
    CSV Data Set Config
    Sampler 2

...同样，如果我找到另一种更好的方法，我将很高兴知道这一点.

...As well, if I find another, better way, I'll be glad to know about it.
