加特林拋出InvalidActorNameException當測試長查詢HTTP請求

Question

我有兩個HTTP端點聊天類服務：

• POST /聊天/用於發佈消息
• GET /聊天/調查/接收消息在長查詢方式

POST請求返回一個錯誤，如果有最後N分鐘內沒有註冊的監聽，所以我必須先製作一個長查詢GET請求。 我試圖用加特林的poll功能，但我發現了一個InvalidActorNameException一些虛擬用戶

的

val scn = scenario("Chat"). 
    feed(csv("users.csv").random). 
    exec(session => session.set("test-user-name","${userEmail}")). 
    exec(authenticateInSamlService). 
    exec(
     polling. 
     every(100 millis). 
     exec(
      http("Poll Chat Mesages"). 
      get("/chat/poll/") 
      queryParam("test-user-name","${test-user-name}") 
      header("X-Session-Id", "Session0") 
      check status.is(200) 
      check bodyString.is("YOMOMMA") 
     ) 
    ). 
    pause(2 seconds). 
    exec(
     http("Send Chat Messag"). 
     post("/chat/") 
     queryParam("test-user-name","${test-user-name}") 
     header("Content-Type", "application/octet-stream") 
     header("X-Session-Id", "Session2") 
     body StringBody("YOMOMMA") 
     check status.is(201) 
    ). 
    pause(2 seconds). 
    exec(polling.stop) 

setUp(scn.inject(
    atOnceUsers(1), 
    rampUsers(20) over (20 seconds) 
).protocols(httpConf))

我可以使用加特林測試長時間輪詢請求還是尚未支持？
