javascript - 加特林不会保存访问 token

Question

在下面的示例中，我可以看到 token 的路径是正确的，因为当我更改它时，我会收到诸如 find.exists 之类的错误。什么也没找到。但由于某种原因我无法保存 token 。我收到“无法构建请求:未定义名为“Token”的属性”

            .headers(autentimata),

            .get("/events?page=0&size=25&relation=ASSIGNEE,CREATOR&status=OPEN,REOPEN,FINISHED,ARCHIVED&sort=createdDate,desc")
            .headers(autentitud)
            .header("authorization", "Bearer ${Token}")


    setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)
}

Answer 1

我认为问题出在这一行:

"authorization" -> "Bearer ${Token}"

从此 block :

 val autentitud = Map(
        "Accept" -> "application/json, text/plain, */*",
        "Origin" -> "https://testsite.com",
        "authorization" -> "Bearer ${Token}")

因为没有定义名为“Token”的属性表明您正在尝试使用尚 undefined variable 。事实上，您仅在场景执行期间保存Token。

加特林文档指出 Expession EL :

This Expression Language only works on String values being passed to Gatling DSL methods. Such Strings are parsed only once, when the Gatling simulation is being instanciated.

因此，解决方案是重构代码并将 block 传递到 header 内，即使这意味着代码重复。

您可以尝试通过打印其值来验证您的 token 是否已被提取，如下所示:

.exec{
        session=>{
                println(" Token value" + session("Token").as[String])
                session

      }}
