Jmeter：动态生成请求时未填充的值

Question

    JDBCRequest - Written query to get data from database
        JSR223 PostProcessor 
ThreadGroup - CreateTransaction
    IFController - ${__jexl3("${udvBranchCode}"== "",)} If udvBranchCode is blank then only run JDBCRequest
        ModuleController - Pointed to JDBCRequest JSR223 PostProcessor
HttpRequest
    JSR223 PreProcessor - Here checking I am checking if udvBranchCode has value; if not then value from the database will get set.

下面是详细信息1. JDBCRequest的JSR223后处理器

这里我正在检查resultSet的大小，然后将分支代码随机存储为属性。

resultSet = vars.getObject("resultSetUserDetails")
if (resultSet.size() !=0 ) {
    Random random = new Random()
    int i = random.nextInt(vars.getObject("resultSetUserDetails").size())
    strBranchCode = vars.getObject("resultSetUserDetails").get(i).get("BranchCode")
    props.put("propsBranchCode" + ctx.getThreadNum(), strBranchCode)
} 

2。 HttpRequest详细信息 IFController

如果分支代码值在用户定义的值中为空，那么我正在调用数据库。

${__jexl3("${udvBranchCode}"== "",)}

3. HttpRequest详细信息

{
  "TR": {
     "BranchCode": "${brnCode}"  -> Here brnCode is not populating
     "CustomerType": "${udvCustomerType}"
   }
   "Individual": {
        "FirstName": "Deepak",
        "MiddleName": "Kumar",
        "LastName": "Verma",
   }
   "Company": {
        "CompanyName": "Company",
        "StartDate": "23/01/2020",
    }
}

4. 上面HttpRequest的JSR223预处理器详细信息

这里，我正在检查用户定义的值中是否不存在分支代码，然后设置从数据库获取的代码。同样基于客户类型，从请求中删除各个对象/元素也可以正常工作。但是对于BranchCode，我遇到了问题，这里不是填充BranchCode值，而是填充了“ $ {brnCode}”。

import groovy.json.JsonSlurper
import groovy.json.JsonOutput

def oldRequest = new JsonSlurper().parseText(sampler.getArguments().getArgument(0).getValue())

def bcode = props.get("propsBranchCode" + ctx.getThreadNum())
if (vars.get("udvBranchCode").isEmpty() == true) {
    vars.put("brnCode", bcode)
} else {
    vars.put("brnCode", vars.get("udvBranchCode"))
}

if (oldRequest.Transaction.CustomerType.equalsIgnoreCase("Individual")) {
    oldRequest.remove("Company")
}

def newRequest = new JsonOutput().toJson(oldRequest)
sampler.getArguments().removeAllArguments()
sampler.setPostBodyRaw(true)
sampler.addNonEncodedArgument('',new JsonOutput().prettyPrint(newRequest),'')

Answer 1

已通过替换为[[HttpRequest的JSR223预处理器详细信息]来解决此问题，>

vars.put（“ brnCode”，bcode）与

oldJSONRequest.TR.BranchCode = bcode

下

import groovy.json.JsonSlurper
import groovy.json.JsonOutput

def oldRequest = new JsonSlurper().parseText(sampler.getArguments().getArgument(0).getValue())

def bcode = props.get("propsBranchCode" + ctx.getThreadNum())
if (vars.get("udvBranchCode").isEmpty() == true) {
    oldJSONRequest.TR.BranchCode = bcode 
} else {
    oldJSONRequest.TR.BranchCode = vars.get("udvBranchCode")
}

if (oldRequest.Transaction.CustomerType.equalsIgnoreCase("Individual")) {
    oldRequest.remove("Company")
}

def newRequest = new JsonOutput().toJson(oldRequest)
sampler.getArguments().removeAllArguments()
sampler.setPostBodyRaw(true)
sampler.addNonEncodedArgument('',new JsonOutput().prettyPrint(newRequest),'')
