I have a request generated by putting map of parameters
val reqUrl = url("http://example.com")
val req = reqUrl << Map("key" -> "value")
I need to get request body in order to calculate it's hash. I'm trying this way
val data = req.toRequest.getStringData
println(data)
but it results null.
The request you currently defined is a GET request which normally has no body. So null is the expected body value.
You could try using a POST as described here : http://dispatch.databinder.net/HTTP+methods+and+parameters.html.
val reqUrl = url("http://example.com")
val postReq = reqUrl.POST
val req = postReq << Map("key" -> "value")
req.toRequest.getStringData

I have to send following curl POST request in my akka code where it is sending both json payload and file in the request:
curl \
-F "payload=</tmp/upload_file_payload.json" \
-F "file=#/tmp/file.pdf" \
-v https://host/api
I am trying to implement the same in akka-http, but not sure exactly how to do it. I found some example here and here, but it is not working as it is, so I have written following code, which also have some error, but seems like I am close:
val httpEntity = HttpEntity(MediaTypes.`application/octet-stream`, file, 100000)
// val httpEntity = HttpEntity.fromPath(ContentType.apply(MediaTypes.`application/octet-stream`), Paths.get(file.getAbsolutePath))
val fileFormData = Multipart.FormData.BodyPart.Strict("file", httpEntity, Map.empty)
val jsonFormData = Multipart.FormData.BodyPart.Strict("payload", payload, Map.empty)
// Multipart.FormData.Strict(scala.collection.immutable.Seq(jsonFormData, fileFormData)).toEntity()
val entity = Multipart.FormData( Source(List(jsonFormData, fileFormData))).toEntity()
val httpRequest = HttpRequest(HttpMethods.POST, uri = uri, entity = entity)
But this code is not compiling.
In between, when I made the code compile, I was getting error:
411 Length Requered
I tried added Content-Length header with request but no avail.
Finally after looking at the akka-http code and more attempts, finally I got this working as following, explanation in comments:
val httpEntity = HttpEntity(MediaTypes.`application/octet-stream`, file, 100000).toStrict(10.seconds)(mat) // I had to convert this into strict: which adds Content-Length and tells it is not streaming
val fileFormData = Multipart.FormData.BodyPart.Strict("file", Await.result(httpEntity, 10.seconds), Map.empty) // used Await here to get httpEntity from Future, this might be made better
val jsonFormData = Multipart.FormData.BodyPart.Strict("payload", payload, Map.empty)
val entity = Multipart.FormData(jsonFormData, fileFormData).toEntity() // Corrected this signature
val httpRequest = HttpRequest(HttpMethods.POST, uri = uri, entity = entity)
To avoid 411 error I had to make FormData strict, whcih itself adds required Content-Length header.
I'm trying to parse a response header value (which is a string) of one request into another method or function in gatling. Here is what I tried
val scn = scenario("DeviceAuth")
.feed(csvFeeeder)
.exec(http("Request1")
.post("endpoint")
.headers(headers_0)
.formParam("key", "value")
.check(headerRegex("header","pattern.*)").saveAs("value"))
.check(status.is(401)))
object getHeader{
def authenticationHeader: String = {
val header: String = "${value}"
val s = header.split("")
--so on and so forth--
}
}
So, when I tried to print the header value, it's just printed "${value}.
How can we pass that value into my function?
Please try this solution
val scn = scenario("DeviceAuth")
.feed(csvFeeeder)
.exec(http("Request1")
.post("endpoint")
.headers(headers_0)
.formParam("key", "value")
.check(headerRegex("header","pattern.*)").saveAs(value))
.check(status.is(401)))
object getHeader{
def authenticationHeader: String = {
val header: String = `$value`
val s = header.split("")
--so on and so forth--
}
}
I'm trying to connect to an IAM controlled ElasticSearch domain, I've created a request, and signed it, and everything works fine for method GET, but on method POST I get a 400 Bad Request
This clearly has something to do with the payload. If I provide a payload empty string ("") it works apporpriately, but anything else results in a bad request.
What am I missing?
val url = s"https://$host/TEST/article/_search"
val serviceName = "es"
val regionName = "us-east-1"
val request = new DefaultRequest(serviceName)
val payload =
"""{"1":"1"}""".trim
val payloadBytes = payload.getBytes(StandardCharsets.UTF_8)
val payloadStream = new ByteArrayInputStream(payloadBytes)
request.setContent(payloadStream)
val endpointUri = URI.create(url)
request.setEndpoint(endpointUri)
request.setHttpMethod(HttpMethodName.POST)
val credProvider = new EnvironmentVariableCredentialsProvider
val credentials = credProvider.getCredentials
val signer = new AWS4Signer
signer.setRegionName(regionName)
signer.setServiceName(serviceName)
signer.sign(request, credentials)
val context = new ExecutionContext(true)
val clientConfiguration = new ClientConfiguration()
val client = new AmazonHttpClient(clientConfiguration)
val rh = new MyHttpResponseHandler
val eh = new MyErrorHandler
val response =
client.execute(request, rh , eh, context);
note: if you run into this problem, inspect the actual content of the response, it may be a result of a mismatch between the index and your query.
My problem was that the specific query I was using was inappropriate for the specified index, and that resulted in a 400
I don't know how to send multipart data in play scala Test case(Specs2).
In my project, method receives multipart data, code look like this
def school_register() = Action(parse.multipartFormData) { implicit request =>
}
In my test case using Specs2 how to form multipart data manually and want hit the school_register method. Once method hitted values are inserted into DB. I have four parameters regno=100,name="xxxx", address="xxx", std=5. Without multipart its working but i have to use multipart data.
Without Multipart i'm using like this
"com.example.schooladmin" should {
"responds with 200 for addSchoolRegister action with all required parameters" in new WithApplication {
val controller = new TestController()
val result = controller.school_registerr() .apply(FakeRequest().withFormUrlEncodedBody(
“Reg No” -> “100”,“Name” -> “XXX”,“Address” -> “XXXXX”,“std” -> “5”))
status(result) must equalTo(OK)
}
}
Here is how I'm doing this, I create a temporary file and I post it with withMultipartFormDataBody:
val tempFile = TemporaryFile(new java.io.File("../server/idCards/5e7b7c6c-98b3-4245-a5fb-405c9cc904f4"))
val part = FilePart[TemporaryFile](key = "picture", filename = "the.file", contentType = Some("image/jpeg"), ref = tempFile)
val formData = MultipartFormData(dataParts = Map(), files = Seq(part), badParts = Seq(), missingFileParts = Seq())
val Some(result) = route(FakeRequest(userDomain.routes.UserController.createIdCard())
.withMultipartFormDataBody(formData))
status(result) mustEqual OK
I can't seem to set a cookie using Dispatch. The server resends a new session ID implying that the one I tried to send didn't get sent in the right way. Here is the code:
val domain = "myhost.com"
val host_req = host(domain).secure
val request = host_req / "path" / "path"
def post = request << Map("key" -> "SomeValue")
val response: Either[Throwable, Map[String, String]] =
Http(post OK asHeaders).either()
//The cookie comes down in the form "Set-Cookie: SESSIONID=<somesession>; Path=/path/; HttpOnly"
//successfully retrieves the session id...
val sessionId = getSessionId(response)
println(sessionId)
val sessionCookie = new com.ning.http.client.Cookie(domain, "SESSIONID", sessionId, "/path/", -1, true)
request.POST.addCookie(sessionCookie)
def establishPost = request << Map("key" -> "SomeValue")
establishPost.addCookie(sessionCookie)
val establishResponse: Either[Throwable, Map[String, String]] =
Http(establishPost OK asHeaders).either()
//Server sends down new SESSIONID...
//sessionId != getSEssionId(establishPost)
This is using the newest version of Dispatch. I'm trying to learn Scala as I go, and the only thing I can't figure out how to do either is inspect the establishPost object for its headers before it is sent as a request.
This should be better:
def reqWithParams = request << Map("key" -> "SomeValue")
val reqWithCookies = reqWithParams.addCookie(sessionCookie)
addCookie method returns the new object (the one with a cookie), but your code didn't use it.
