如何基于jmeter中的先前响应值绕过采样器? [英] how to Bypass the Sampler based on previous response value in jmeter?

问题描述

我陷入了一种情况，在这种情况下，我需要验证某个值中前一个采样器的响应，如果该值是[]，则我需要触发以下请求，否则切换到另一个采样器.

I have caught up in a situation, where in i need to verify the response of the Previous Sampler for one of the value and if the Value for that is [], then i need to trigger the below request or else then switch to another Sampler.

Flow:
Check Response of Sampler for One of the attribute
IF(attribute value==[])
Execute the Sampler under IF Conditions.
ELSE
New Sampler

样品响应: {"id":8，"merchant_id":"39"，"title":"Shirts-XtraLarge"，"subtitle":null，"price":110，"description":null，"images":"image_thumbs" :[[]]，"options":[]，"options_available":[]，"custom_options":[]}

Sample Response: {"id":8,"merchant_id":"39","title":"Shirts-XtraLarge","subtitle":null,"price":110,"description":null,"images":"image_thumbs":[[]],"options":[],"options_available":[],"custom_options":[]}

我需要检查custom_options属性是否为空！如果为空，请执行一些操作，如果不为空，请执行其他操作！

I need to check if the attribute custom_options is empty or not! If Empty do some actions and if not empty do some other action !

需要条件来模拟这一点！

Need if condition to simulate this!

帮助很有用！

选择切换控制器

1. 将 JSR223 PostProcessor 添加为返回您JSON的请求的子代

2. 将以下代码放入脚本"区域:

1. Add JSR223 PostProcessor as a child of the request which returns your JSON

2. Put the following code into "Script" area:

def size = com.jayway.jsonpath.JsonPath.read(prev.getResponseDataAsString(), '$..custom_options')[0].size()
if (size == 0) {
    vars.put('size', 'empty')
} else {
    vars.put('size', 'notempty')
}

将切换控制器添加到您的测试计划中，并使用${size}作为切换值"

Add Switch Controller to your Test Plan and use ${size} as "Switch Value"

添加另一个简单控制器作为交换控制器的子代，并为其赋予notempty名称.将与不为空的"custom_options"相关的请求放在该notempty简单控制器下.

Add another Simple Controller as a child of the Switch Controller and give notempty name to it. Put request(s) related to not empty "custom_options" under that notempty Simple Controller.
