我遇到了测试脚本的问题。在我到达 for 循环之前，一切似乎都运行良好。我正在尝试对登录响应中保存到 ${items} 的每个值执行 itemChain 中的所有操作。

我收到以下错误：

12:08:30.460 [ERROR] i.g.c.a.InnerWhile - Could not evaluate condition: Can't cast value item1 of type class java.lang.String into interface scala.collection.Seq, exiting loop

当您编写用于获取项目的 JsonPath 表达式时，您使用了默认基数，即 find (= find(0))。

如果你想提取所有这些，并得到一个序列，而不是单个元素，你必须使用 findAll：https ://gatling.io/docs/current/http/http_check/#http-check-extracting
