我正在尝试使用 JSR223 预处理器在 jmeter 中使用 csv 数据创建一个动态 json
以下是我使用 CSV 作为 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,我收到带有错误请求的HTTP 400
日志消息如下所示:

CSV如下:
-1,BatteryStatus
-3,AvailableMemory
-5,AvailableStorage
提前谢谢你
您必须在此处使用{}
作为闭包:
items.collect() { // wrong: [
// ...
} // wrong: ]
或者只是items.collect { ... }
使用[]
编译器将看到它作为映射文字,并且您得到上述错误(it
未定义(
我相信您应该更准确地复制和粘贴示例代码,以便您的"项目"部分应如下所示:
Items: items.collect() {
[
Id : it.Id,
Name: it.Name
]
}
另请注意,您不应该直接在Groovy脚本中使用JMeter函数和/或变量,因为它与GString Template功能冲突,并且无法缓存已编译的脚本,从而对性能产生负面影响。
所以我也建议更改:
${__P(DeviceFamily)
到props.get('DeviceFamily
('${__time(yyyy-MM-dd'T'hh:mm:ss)}
到new Date().format("yyyy-MM-dd'T'hh:mm:ss")
- 等。
