如何使用Jmeter存储整个响应并为下一次休息呼叫更新它 [英] How to store entire response and update it for next rest call using Jmeter

问题描述

问题:如何提取整个restAPI响应并使用某些值对其进行修改，以及如何将更新后的响应用于后续的rest调用.我正在使用Jmeter

Question: How to extract entire restAPI response and modify it with some values and use the updated response for sub-sequent rest call. I am using Jmeter

我有一个POST呼叫，例如:"/check1/id1/post"
POST正文:

I have one POST call ex: "/check1/id1/post"
POST body :

{ 
                "test":"rest",
                "check" :{ 
                           "id":1,
                           "name": "xyz"
                         }
             }

POST呼叫响应:

{ 
            "test":"rest",
            "check" :{ 
                       "id":1,
                       "name": "xyz"
                       "status":"updated"
                     }
         }

================================================ =====================

=====================================================================

问题:现在，我必须在下一个POST调用主体中使用整个上面的RESPONSE，如下所示，但是，我想将"id"值更新为2，然后需要进行POST调用.

QUESTION: Now, I have to use entire above RESPONSE in next POST Call body as below, BUT, I wanted to update "id" value as 2 and then need to POST rest call.

REST CALL:------>"/check1/id2/post" 发布身体如下:------->

REST CALL: ------ > "/check1/id2/post" POST BODY as below : ------->

{ 
            "test":"rest",
            "check" :{ 
                       "id":2,
                       "name": "xyz"
                       "status":"updated"
                     }
         }

任何人都可以对此进行指导吗? ，对于如何解决此问题一无所知?，我需要使用Jmeter解决.

Can anyone please guide on this? , I am clueless about how to solve this issue?, I need to solve this using Jmeter.

推荐答案

您可以使用 JSR223预处理器

假设有效的JSON

{ 
            "test":"rest",
            "check" :{ 
                       "id":1,
                       "name": "xyz",
                       "status":"updated"
                     }
         }

以下是步骤

1. 将JSR223预处理器添加到第二个发布请求中.

2. 将以下代码添加到预处理器

1. Add a JSR223 preprocessor to the 2nd post request.

2. Add the following code to the preprocessor

导入groovy.json.JsonBuilder

import groovy.json.JsonBuilder

导入groovy.json.JsonSlurper

import groovy.json.JsonSlurper

def slurped = new JsonSlurper().parse(prev.getResponseData())

def slurped = new JsonSlurper().parse(prev.getResponseData())

def builder =新的JsonBuilder(含糊) builder.content.check.id ='2' vars.put("POSTDATA"，builder.toPrettyString())

def builder = new JsonBuilder(slurped) builder.content.check.id = '2' vars.put("POSTDATA",builder.toPrettyString())

以上代码将ID值更新为2并将JSON存储在POSTDATA中，您可以使用${POSTDATA}发布JSON FILE

Above code will update ID value with 2 and stores the JSON in POSTDATA , you can use ${POSTDATA} to post the JSON FILE

在我的预处理器中，我使用prev.getResponseData()保存响应，这意味着该预处理器必须随第一个采样器的旁边的采样器一起提供.

In my pre processor i'm saving the response using prev.getResponseData() , that means this pre processor must included with the sampler right next to the first sampler.
