我的代码：

package load
import io.gatling.core.scenario.Simulation
import io.gatling.core.Predef._
import io.gatling.http.Predef._
import scala.concurrent.duration._

class LoadScript extends Simulation{

 val httpConf = http
  .baseURL("http://blabla.com:5000")
  .authorizationHeader("Bearer 35dfd7a3c46f3f0bc7a2f06929399756029f47b9cc6d193ed638aeca1306d")

 val basicLoad = scenario("BASIC_LOAD").exec(BasicLoad.start)

 setUp(
   basicLoad.inject(rampUsers(1) over (1 minutes))
  .protocols(httpConf))
 }

 object BasicLoad {
   val start =
   exec(
    http("HTTP Request createCompany")
      .post("/Companies/CreateCompanyAndStartTransaction")
      .queryParam("inn","7733897761")
      .queryParam("ogrn","5147746205041")
      .check(status is 200, jsonPath("$.id").saveAs("idCompany"))
  )
}

当您不发送消息正文时，您需要添加 .header("Content-Length", "0")作为解决方法。我有类似的问题。我在两个环境上运行测试，不同之处在于应用程序基础结构。测试通过了Amazon AWS，但在Azure上获得了HTTP 411。因此，问题似乎不在于加特林本身。

Gatling小组在和的聊天记录中也很好地回答了这个问题： https://groups.google.com/forum/#!topic/gatling/mAGzjzoMr1I

Answer 2

我刚刚将加特林从2.3升级到3.0.2。他们编写了自己的HTTP客户端，它现在发送content-length：0，但此错误中描述的一种情况除外： https://github.com/gatling/gatling/issues/3648

因此，如果您避免将httpRequest（）的方法类型作为字符串使用，例如：

exec(http("empty POST test").httpRequest("POST","https://gatling.io/"))

并按以下方式使用post（）：

exec(
http("HTTP Request createCompany")
  .post("/Companies/CreateCompanyAndStartTransaction")...

或

exec(
http("HTTP Request createCompany")
  .httpRequest(HttpMethod.POST, "/Companies/CreateCompanyAndStartTransaction")

然后将Gatling升级到3.0.2就足够了。否则，您需要等待Gatling 3.0.3

响应411 Gatling所需的长度
