如何使用AWS Signature版本4发送停车请求？

Question

我正在尝试使需要在AWS上托管的Pod上产生负载的方案自动化。他们需要使用“ AWS签名版本4”进行身份验证。

我不确定如何通过加特林发送“ AWS签名版本4”的请求。AWS Signature版本4采用这些值。

1. AccessKey
2. SecretKey
3. AWS地区
4. 服务名称

返回

"X-Amz-Date":
"Authorization": "AWS4-HMAC-SHA256 Credential=AccessKey/us-east-1/apigateway/aws4_request, SignedHeaders=content-length;content-type;host;x-amz-date, Signature="somevalue",

提供所有这样的值会有所帮助吗？

.exec(http("RESTGetOAuthToken")
          .post("")
          .header("Content-Type", "application/x-www-form-urlencoded")
          .header("Content-Type", "application/json")
          .header("X-Amz-Date", "")
          .header("Authorization", "")
          .header("Cache-Control", "no-cache")
        .body(StringBody("""{
  "orders": [
      ]
    }
  ]

您需要生成X-Amz-日期和授权详细信息，并将其与标头一起传递。您可以使用下面的类来提取这两个信息。

[https://github.com/sandipperf/AWS_API_Request_Gatling/blob/master/RequestSigner.scala通过提供ASWAccessKey和AWSSecretKey提取AWS签名密钥。

**这是导入RequestSigner类**之后如何从scala测试类中提取信息的方法

/ ** ********************************************* ******生成AWS Signature密钥************************************** /val AwsAccessKey =“ XXXXXXXXXXXX”val AwsSecretKey =“ XXXXXXXXXXXXXXXXXXXXXXXX”

val signature = RequestSigner.sign(
        uriPath = "/Your/URL/HERE",

        method = "POST",
        //body = Some("""{ "hello": "foo" }"""),
        body = Some(requestBuildBody),

//您需要传递requestBuildBody i.eyour您将与postrequest一起传递的实际请求正文

        headers = Seq(("Host", List("XXXXXXXX.execute-api.us-XXXX-2.amazonaws.com"))),
        queryParameters = Seq.empty,
        credentials = new BasicAWSCredentials(AwsAccessKey, AwsSecretKey),
        region = "us-XXXX-2",
        service = "execute-api")


      val amzStamp = (signature.toString).substring(18, 34)
      val sign = (signature.toString).substring(35, 223)
      AmazonTimeDetails.append(amzStamp).toString
      SignatureDetails.append(sign).toString

从上面的代码中，您将获得X-Amz-Date和signatureDetails，需要在标头中使用

    "Host" -> "XXXXXX.execute-api.us-XXXX-X.amazonaws.com",
    "Content-Type" -> "application/json",
    "X-Amz-Date" -> "${amazonTimeDetails}",
    "Authorization" -> "${signatureDetails}")
