testing - 从 Gatling 中的编码响应中提取数据

问题描述

我在从一个响应中提取数据时遇到问题，我在 Fiddler 中对其进行了检查，并收到消息表明此响应已编码： https ://i.postimg.cc/G3VfMtxh/2019-10-15-12-31-41- Progress-Telerik-Fiddler-Web-Debugger.png

当我将此内容复制到https://jsonpath.com/时，我看到 https://i.postimg.cc/rpYP4wh4/2019-10-14-22-41-19-jsonpath-online-evaluator.png

所以我尝试使用正则表达式，我在这里检查了它https://regex101.com/ https://i.postimg.cc/DZ6m6RX1/2019-10-14-22-58-57-Online-regex-tester-and -调试器-PHP-PCRE.png

它可以在在线编辑器中使用，但是脚本存在问题。

            .get("/UploadedFiles/5899f868-8473-4dfc-a39c-f13a94c47b3a.jpeg")
            .headers(headers_3),
            http("request_10")
            .get("/UploadedFiles/26ac4d69-8a63-4575-bec4-849d5a5e194a.png")
            .headers(headers_3),
            http("request_11")
            .get(uri1 + "/start?transport=serverSentEvents&clientProtocol=1.5&Authorization=Bearer%20${authToken}&connectionToken=${MyConnectionToken}&connectionData=%5B%7B%22name%22%3A%22livechat%22%7D%5D")
            .headers(headers_6)))
val printSesssionVar = scenario("print session var")
    .exec{session => println(session("printSesssionVar").as[String])
      session}
    setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)
}

但是在这两种情况下我都会出错

> request_11: Failed to build request: No attribute named 'MyCon      1 (50.00%)
nectionToken' is defined
> status.find.in(200,201,202,203,204,205,206,207,208,209,304), f      1 (50.00%)
ound 404

我试图在 request_6 上提取它并在 request_11 上使用它。

是否可以处理此请求？在其他方面，我毫无问题地提取不记名令牌。

解决方案

MyConnectionToken您已经在上面注释掉了这两个提取，但我想您已经知道了？

.exec { session =>尝试通过将块放在同一请求链中并将其打印出来，即：

// ... other code above
http("request_11")
            .get(uri1 + "/start?transport=serverSentEvents&clientProtocol=1.5&Authorization=Bearer%20${authToken}&connectionToken=${MyConnectionToken}&connectionData=%5B%7B%22name%22%3A%22livechat%22%7D%5D")
            .headers(headers_6)))
               .exec{session => println(session("printSesssionVar").as[String])
                session}

因为您声明val printSesssionVar = scenario会话中保存的变量没有被继承。
