Groovy创建动态json

标签: groovy jmeter jsr223 jsonbuilder

我正在尝试使用JSR223 PreProcessor在jmeter中使用csv数据创建动态json

以下是我使用CSV来存储ID和名称数据的代码:

def builder = new groovy.json.JsonBuilder()

@groovy.transform.Immutable
class Items {
    String Id
    String Name
}

def items = new File("Item.txt").readLines().collect { line -> new Items(line.split(",")[0], line.split(",")[1]) }
builder.Rule(

        __type: "DataCollectionRule",
        DeviceFamily: '${__P(DeviceFamily)}',
        RuleId: 0,
        Name: 'test-${__time(yyyy-MM-dd'T'hh:mm:ss)}-${__counter(TRUE,)}',
        Targets:
                [
                        Groups :
                                [
                                        [
                                                Id: '${logicalid1_1}',
                                        ]
                                ],
                        Devices:
                                [

                                ]
                ],
        StartDate: '/Date(${__time(,)})/',        
        IsEnabled: true,
        Priority: 0,
        AlertType: 0,
        DeliverySchedule:
                [
                                                Id         :   1,
                                                Name       :  "Every 30 Minutes",
                                                Period     :  "30M"

                ],
        CollectionSchedule:                      
               [
                                              Id         :   1,
                                                Name       :  "Every 30 Minutes",
                                                Period     :  "30M"
              ],                    
        Items  : items.collect() [
        [

                                                Id         : it.Id,
                                                Name       : it.Name                                                

        ]
                ],
        LocationAccuracy:
                [
                                                UseGPS     :  false,
                                       DistanceInMeters : 100,
                                       ReportToServer  : true,
                                       AccuracyInMeters : 10
             ],
          HasDolphinCounters: false,
          EnrollmentCertificateId: null,
          EnrollmentCertificateName: "",
        DatabaseHighWatermark: 28,
        DatabaseLowWatermark: 14,
        DeviceHighWatermark: 400,
        DeviceLowWatermark:  200

)

sampler.getArguments().removeAllArguments()
sampler.addNonEncodedArgument('', builder.toPrettyString(), '')
sampler.setPostBodyRaw(true);

运行测试时,我收到HTTP 400的请求错误

提前谢谢

2 个答案:

答案 0 :(得分:1)

您必须在此处使用{}作为闭包:

items.collect() { // wrong: [
    // ...
} // wrong: ]

或者只是items.collect { ... }

使用[],编译器将其视为地图文字,并且您遇到上述错误(it未定义)

答案 1 :(得分:0)

我相信您应该更准确地复制和粘贴example code,以使“项目”部分看起来像这样:

Items: items.collect() {
    [
            Id  : it.Id,
            Name: it.Name
    ]
}

还请注意,您不应直接在Groovy脚本中使用JMeter Functions and or Variables,因为它与GString Template功能冲突并且使caching of compiled scripts不可能对性能产生负面影响。

所以我也建议更改:

  • ${__P(DeviceFamily)props.get('DeviceFamily)`
  • ${__time(yyyy-MM-dd'T'hh:mm:ss)}new Date().format("yyyy-MM-dd'T'hh:mm:ss")
