在加特林中将标头从一个请求传递到另一个请求

Question

我试图将令牌从第一个请求的responseHeader 传递到循环中的后续请求。但是，我不断收到错误消息，指出“continuationToken”（如示例中所示）未定义

val httpProtocol = http
    .baseUrl("some-base-url")

  val scn = scenario("Scenario for 'Get store assortments by storeId'")
    .exec(http("request_1")
      .get("endpoint1")
      .header("api-key","api-key")
      .queryParam("param", true)
      .check(header("continuationToken").saveAs("${continuationToken}")))
    .doWhile(session => session("${continuationToken}").as[String] != null) {
      exec(http("request_2")
        .get("endpoint1")
        .header("api-key", "api-key")
        .queryParam("param", true)
        .queryParam("continuationToken", "${continuationToken}")
        .check(header("continuationToken").saveAs("${continuationToken}")))
    }
        setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)

错误：

Answer 1

您的

request_1

请求失败：

status.find.in([200, 209], 304), found 400

。 因此，它无法成功捕获预期的标头：它很可能仅在请求成功并返回 200 时才出现。

降低 logback conf 文件中的日志记录级别，检查您的负载，然后找出服务器响应“400：错误请求”的原因。
