我想调用’myActionID’变量的值.我怎么做？

如果我将像“actionId”：1368201这样的静态值传递给myActionID然后它可以正常工作,但如果我使用“actionId”：${actionIdd}则会出错.

这是相关的代码：

class LaunchWorkflow_Act extends Simulation {

val scenarioRepeatCount = 1

val userCount = 1

val myActionID = "13682002351"

val scn = scenario("LaunchMyFile")

.repeat (scenarioRepeatCount) {

exec(session => session.set("counter", (globalVar.getAndIncrement+" "+timeStamp.toString())))

.exec(http("LaunchRequest")

.post("""/api/test""")

.headers(headers_0)

.body(StringBody(

"""{ "actionId": ${myActionID} ,

"jConfig": "{\"wflow\":[{\"Wflow\":{\"id\": \"13500145349\"},\"inherit-variables\": true,\"workflow-context-variable\": [{\"variable-name\": \"externalFilePath\",\"variable-value\": \"/var/nem/nem/media/mount/assets/Test.mp4\"},{\"variable-name\": \"Name\",\"variable-value\": \"${counter}\"}]}]}"

}""")))

.pause(pause)

}

}

setUp(scn.inject(atOnceUsers(userCount))).protocols(httpProtocol)

一切正常如果我把值13682002351而不是myActionID.提前致谢.在Gatling中执行此脚本时我遇到此错误

ERROR i.g.http.action.HttpRequestAction – ‘httpRequest-3’ failed to

execute: No attribute named ‘myActionID’ is defined

解决方法:

Scala具有各种字符串插值机制(参见docs),可用于将变量嵌入字符串中.所有这些都可以与用于创建多行字符串的三重引号“”“结合使用.

在这种情况下,您可以使用：

val counter = 12

val myActionID = "13682002351"

val str = s"""{

"actionId": $myActionID ,

"jConfig": "{\"wflow\":[{\"Wflow\":{\"id\": \"13500145349\"},\"inherit-variables\": true,\"workflow-context-variable\": [{\"variable-name\": \"externalFilePath\",\"variable-value\": \"/var/nem/nem/media/mount/assets/Test.mp4\"},{\"variable-name\": \"Name\",\"variable-value\": \"${counter}\"}]}]}"

}"""

请注意s前置于字符串文字,并且美元符号前置于变量名称.
