gatling负载测试中的动态标头

我尝试使用json feed使用以下代码为每个请求动态生成标头:

import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration._

class LoadTest extends Simulation {

val httpConf = http
.baseURL("http://example.com")

val tokensFeeder = jsonFile("Tokens.json");

val user1 = scenario("Download")
  feed(tokensFeeder)
  .exec(
    http("req")
     .post("/download")
     .headers("${header}")
     .body(StringBody("""{ "Device_Type":"iOS","Locations":[{"Latitude":"51.50719197","Longitude":"-0.127214091"}] }""")).asJSON
  )

setUp(
user1.inject(atOnceUsers(2)) 
).protocols(httpConf)
}

Tokens.json的数据格式如下:

[
   {"header" : {"token" : "12234"}},
   {"header" : {"token" : "12235"}},
   {"header" : {"token" : "12236"}}
]

但是我收到以下错误:

type mismatch;
found   : String("${header}")
required: Map[String,String]
11:23:07.862 [ERROR] i.g.c.ZincCompiler$ -          .headers("${header}")
11:23:07.864 [ERROR] i.g.c.ZincCompiler$ -                   ^
11:23:07.908 [ERROR] i.g.c.ZincCompiler$ - one error found
11:23:07.910 [ERROR] i.g.c.ZincCompiler$ - Compilation crashed
sbt.compiler.CompileFailed: null

据我所知,馈线包含地图矢量,所以不应该&#t;#34; $ {header}"评价为{token:12234}?

任何帮助都将不胜感激。

答案 0 :(得分:1)

修正了标题的以下更改:

.headers(Map("token" -> "${header.token}"))
