加特林的動態值的相關性

Question

我想在Gatling加載工具中關聯或創建一個「檢查」，但不知道如何去做。我通過官方Gatling網站的高級教程文檔，但無法準確找到動態值的相關性。

下面是代碼從我的腳本

.feed(feeder) 

    .exec(http("EnterDetails") 
     .post("/events/review.action") 
     .headers(headers_6) 
     .formParam("userInfo.spgEmail", "")

     .headers(headers_3)) 

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

的peice的在上面的代碼我在

.exec動態購買ID（HTTP（ 「CompleteReservation」） ，其獲取生成從服務器和需要相關。

從加特林文檔，我明白（糾正我，如果我錯了），我們需要檢查元素代碼來獲取CSS路徑。（顯示H ERE）。 Inspect Element

請讓我知道我們如何關聯.TIA。

在加特林你必須使用檢查從響應中提取一個值。看看documentation。

您可以選擇使用regex或xpath來提取標記中的值。但在你的情況下，我建議使用簡單的regex，因爲IMO在你的示例響應中沒有標籤或ID，您可以輕鬆掛鉤xpath。我的意思是說，xpath表達式仍將保持簡單易懂。接下來的事情是提取價值進入會議和事後使用它。

以下是示例場景從example.com收到的響應中提取URI的查詢路徑這是在控制檯事後印刷：

val scn = scenario("Checks") 
    .exec(
    http("root") 
    .get("/") 
    .check(
     // Extracting URI query path from response body via regexp and storing into session 
     regex("""www\.iana\.org/([a-z/]*)""").find.saveAs("queryPath") 
    ) 
) 
    // Printing the value from session 
    // Important thing to note is how you can access stored value from session 
    .exec { session => 
    println(" QUERY PATH --> " + session("queryPath").as[String]) 
    session 
    } 

在你的情況你最後可能會是這個樣子：

.exec(http("CompleteReservation") 
    .get(uri3 + "/s03623649917832?AQB=1&ndh=1&pf=1&t=21%2F3%2F2016%2012%3A46%3A5%204%200&D=D%3D&fid=31A8BC73D5B8ACEB-2B64CD0ACE185774&ce=UTF-8&pageName=Reservation%20Confirmation&g=https%3A%2F%2Fstg.starwoodmeeting.com%2Fevents%2Fconfirm.action&r=https%3A%2F%2Fstg.starwoodmeeting.com%2Fevents%2Freview.action&cc=CAD&purchaseID=20160421_734091125&ch=StarGroups&server=StarGroups&events=purchase&products=%3B271%3B1%3B100.00&c2=SOCIAL&c3=1603295001&c4=271&v4=20160421_734091125&c5=SI&c6=YES&c8=en&s=1600x838&c=24&j=1.6&v=N&k=Y&bw=1042&bh=733&AQE=1") 
    .headers(headers_3)) 
    .check(
     regex("""Your confirmation number is (\d+)""") // Regular expression with group which represents confirmation number. 
     .find 
     .saveAs("confirmationNumber") // Now the extracted regexp group is stored in session under "confirmationNumber" as name. 
    ) 
    // Missing, check, transformation or use of value from session 

我不知道你的提取值的用法，因此它在上面的代碼片段中缺少。但是我希望你已經知道如何處理響應以及下一步如何使用提取的值。

我希望它有幫助。
