Gatling - 关联 json 响应并在会话中对其进行修改

如何解决Gatling - 关联 json 响应并在会话中对其进行修改

我执行一个请求并获得响应正文。 我想在下一个请求中使用这个响应体，但在这样做之前需要添加一个 json 节点。 请求 1 => 响应 1：

 {
  "resourceType": "Parameters","parameter": [
    {
      "name": "medication","resource": {
        "resourceType": "Bundle","id": "08eb0474-23a2-429b-93b2-ba38b96271ec","meta": {
          "lastUpdated": "2021-01-18T16:18:22.4474168+00:00","source": "http://base-fhir.qa.forskrivning.no/Patient/$getMedication","profile": [
            "http://ehelse.no/fhir/StructureDefinition/sfm-MedicationBundle"
          ]
        },"type": "document","timestamp": "2021-01-18T16:18:22.4473963+00:00","total": 27,"link": [
          {
            "relation": "self","url": "http://base-fhir.qa.forskrivning.no/Patient/$getMedication"
          }
        ],"entry": [
          {
            "fullUrl": "urn:uuid:8d3fd453-2933-4f39-9c90-4df868080f40","resource": {
              "resourceType": "Composition","id": "a79f08c0-0b3c-4e26-adf4-6fc5d1305b36","meta": {
                "profile": [
                  "http://ehelse.no/fhir/StructureDefinition/sfm-MedicationComposition"
                ]
              },"identifier": {
                "use": "official","value": "9f9fdefe-4c5e-456f-b419-4871645ebd01"
              },"status": "final","type": {
                "coding": [
                  {
                    "system": "http://loinc.org","code": "11503-0","display": "Medical records"
                  }
                ]
              },"subject": {
                "reference": "urn:uuid:75ad528e-2db7-47a6-90cd-3677b9c5c7e4","display": "Agnieszka Øvrelid"
              },"date": "2021-01-18T16:18:22.4183485+00:00","author": [
                {
                  "reference": "urn:uuid:a01b883a-752c-4b02-8b94-c175ff8602b3","display": "Bengt Fos Minde,HPR: 431002790"
                }
              ],"title": "Medication summary","confidentiality": "N","section": [
                {
                  "title": "Medication","code":

我想在再次调用之前将此元素添加到 json 正文的正确位置：

 "relatesTo": [
            {
              "code": "replaces","targetIdentifier": {
                "use": "official","value": "57a9d650-ce21-42b2-a317-7d33a1eb4582"
              }
            }
          ]

完成的请求正文应该是这样的：

    {
  "resourceType": "Parameters","id": "307a7183-06af-465e-b094-8514cdedf9f5","meta": {
          "lastUpdated": "2020-11-06T07:44:28.6590617+00:00","timestamp": "2020-11-06T07:44:28.6590219+00:00","total": 24,"entry": [
          {
            "fullUrl": "urn:uuid:160f33ca-29c6-4ff7-ad9d-366fb17ebe9a","id": "cf61d45e-bae5-44e0-a64e-45f449958c3c","value": "57a9d650-ce21-42b2-a317-7d33a1eb4582"
              },"subject": {
                "reference": "urn:uuid:09d55df4-b2db-45e2-a8b3-9891feef83ea","date": "2020-11-06T07:44:28.6385246+00:00","author": [
                {
                  "reference": "urn:uuid:a4e51226-ea04-4f41-b6b2-b7a1b287f990","display": "Selma Hadland,HPR: 2037661"
                }
              ],"relatesTo": [
                {
                  "code": "replaces","targetIdentifier": {
                    "use": "official","value": "57a9d650-ce21-42b2-a317-7d33a1eb4582"
                  }
                }
              ],"code": {
                    "coding": [
                      {
                        "system": "http://ehelse.no/fhir/CodeSystem/sfm-section-types","code": "sectionMedication","display": "List of Medication statements"
                      }
                    ]
                  },

如何获取响应并在会话中动态添加元素？

解决方法

这里有两个想法：

• 使用会话：

  exec {
    callMyService
      .check(jsonPath("$..*").saveAs("myJson")) 
  }.exec { session =>
    val json = session("myJson").as[Map[String,Any]]
    val newJson = json.updated("relatesTo",Seq(Map("code" -> "replaces",...)))
    // do something
    session
  }
  

• 或使用变换：

  exec(
    callMyService
      .check(jsonPath("$..*").ofType[Map[String,Any]]
        .transform { json =>
          json.updated("relatesTo",..)))
        }.saveAs("myJson")
      ))
  

但是我无法测试这些想法。特别是你要添加的部分的数据格式 - 我不确定。
