无法建立请求：在加特林脚本中未定义名为'token'的属性

Question

我将HAR文件转换为Gatling模拟脚本，但是从请求标头提取令牌时遇到问题。转换后，我有以下代码：

import scala.concurrent.duration._

import io.gatling.core.Predef._
import io.gatling.http.Predef._

但是当我改变

            .get("/api/account")

到

http("request_2")
            .get("/api/account")

                        .check(header("Bearer").saveAs("token"))

我遇到以下错误：https://i.postimg.cc/0yTMKrvm/2019-10-12-23-46-37-C-WINDOWS-system32-cmd-exe.png

我在做什么错？

Answer 1

查看屏幕快照，您得到的错误是：No attribute named 'token' is defined。

这表明您没有保存标题token中的Bearer。

调用/api/account时，请仔细查看HTTP请求-尤其是标头，并检查标头是否如预期的那样存在。您可以为此使用Chrome开发工具或任何HTTP代理。

您可能也想在Gatling中调试脚本，以便可以看到正在捕获的所有变量-有关此内容的一些想法，请参阅此帖子-https://www.james-willett.com/debug-gatling/
