加特林不会保存访问令牌 [英] Gatling won't save access token

问题描述

在下面的示例中，我可以看到令牌的路径是正确的，因为更改令牌时会遇到诸如find.exists之类的错误.一无所获.但是由于某种原因，我无法保存令牌.我无法建立请求:未定义名为令牌"的属性

In this example below, I can see that path to token is correct, because when I change it I get errors such as find.exists. found nothing. Yet for some reason I can't save the token. I get Failed to build request: No attribute named 'Token' is defined

推荐答案

我认为问题出在这一行:

I think that the problem is in this line :

授权"->承载者$ {Token}"

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

从此块:

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

因为未定义名为令牌"的属性，表明您正在尝试使用尚未定义的变量.而且，实际上，您仅在方案执行期间保存 Token .

since No attribute named 'Token' is defined states that you are trying to use a variable not yet defined. And ,indeed, you save Token only during scenario execution.

加特林文档说明 Expession EL :

此表达式语言仅适用于传递给Gatling DSL方法的字符串值.实例化加特林模拟时，此类字符串仅解析一次.

因此，解决方案是重构代码并在标头中传递代码块，即使这意味着代码重复.

So the solution would be to refactor your code and pass the block inside headers, even if it would mean a code duplication.

您可以尝试通过打印出其值来验证您的令牌是否已提取:

And you could try to verify that your token is extracted by printing its value out like this:

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

      }}
