Basic http auth of soap service…

[Viktor Hedefalk]

I'm consuming a soap service that uses basic http auth. Is this the
right way to add credentials:

val service = (new ServiceSoap11Bindings with scalaxb.Soap11Clients
with scalaxb.DispatchHttpClients {
override val httpClient = new DispatchHttpClient {
override def request(in: String, address: java.net.URI, headers:
Map[String, String]): String = {
val http = new Http
http x (url(address.toString) << (in) <:< headers as
("username", "password") as_str)
}
}
...
}

Thanks,
Viktor

That's an intended use case for the cake pattern.

what is the version of net.databinder.dispatch that we should use?

I am using as follows in order to use soap authentication:

    val remote = new MyServicePortBindings with Soap11Clients with DispatchHttpClients {

      override def baseAddress = new java.net.URI(myEndpointURI)

      import dispatch._

      override val httpClient = new DispatchHttpClient {

        override def request(in: String, address: java.net.URI, headers: Map[String, String]): String = {

          println("URL: " + address);

          println("REQUEST: " + in);

          val req = url(address.toString) << in <:< headers as(myLogin, myPassword)

          val s = Http(req OK as.String)

          val out = s()

          println("RESPONSE: " + out);

          out

        }

      }

    };

and this works with:

      <dependency>

        <groupId>net.databinder.dispatch</groupId>

        <artifactId>core_2.10</artifactId>

        <version>0.9.1</version>

      </dependency>

is this the right way? 

(but i have some other strange problems)

however, this example fails to compile with the last correct version of net.databinder.dispatch.

(this is the last correct version of net.databinder.dispatch, right?)

    <dependency>

      <groupId>net.databinder.dispatch</groupId>

      <artifactId>dispatch-core_2.9.2</artifactId>

      <version>0.9.5</version>

    </dependency>

do you know how I should modify the example to make it work?

I also didn't manage to compile the example of Viktor (It does not find the 'x' method for Http).

or, can you please provide an example of calling a soap service with authentication?

Regards,

David

The release note for 1.0.0 says "The default http client for SOAP binding is upgraded to Dispatch 0.9.5,"

so I think that's what should be used. (http://scalaxb.org/scalaxb-100)

Since Viktor's override was based on older version with Dispatch Classic, you might have to tweak it a little.

If I use the standard dispatch used by scalaxb (so, without authentication):

 val remote = new MyServicePortBindings with Soap11Clients with DispatchHttpClients {};

with 

    <dependency>

      <groupId>net.databinder.dispatch</groupId>

      <artifactId>dispatch-core_2.9.2</artifactId>

      <version>0.9.5</version>

    </dependency>

I get the following runtime error:

Exception in thread "main" java.lang.NoSuchMethodError: scala.util.control.Exception$Catch.either(Lscala/Function0;)Lscala/Either;

at scalaxb.DispatchHttpClients$DispatchHttpClient$class.request(httpclients_dispatch.scala:12)

package scalaxb

this is the source generated by scalaxb-maven-plugin 1.0.1:

trait DispatchHttpClients extends HttpClients {

  val httpClient = new DispatchHttpClient {}

  trait DispatchHttpClient extends HttpClient {

    import dispatch._

    def request(in: String, address: java.net.URI, headers: Map[String, String]): String = {

      val req = url(address.toString) << in <:< headers

      val s = Http(req OK as.String)

      s()    // <<< httpclients_dispatch.scala:12), error in the stack trace

    }

  }

}

any idea on this?

You're hitting NoSuchMethodError for standard lib stuff. I suspect there's Scala version mixup that's happening somewhere.

Are you using 2.9.2 for everything?

scala 2.10.0

[David Portabella]

ieppp, i see your point,

it works correctly with:

    <dependency>

      <groupId>net.databinder.dispatch</groupId>

      <artifactId>dispatch-core_2.10</artifactId>

      <version>0.9.5</version>

    </dependency>

thanks,

I just upgraded to dispatch 0.9.5 so the tweak became this:

/** Override http binding to use basic http auth creds */
override lazy val httpClient = new DispatchHttpClient {

override def request(in: String, address: java.net.URI, headers:
Map[String, String]): String = {

import dispatch._

val http = new Http

val req = (Config.CrmSettings.user, Config.CrmSettings.password) match {
case (Some(user), Some(pwd)) => url(address.toString) <<
(in) <:< headers as (user, pwd)
case _ => url(address.toString) << (in) <:< headers
}
val s = Http(req > as.String)
s()
}
}

Thanks,
Viktor

cool, thanks for sharing.

[Leonor Boga]

Hi all, 

The code shared by Viktor Hedefalk is quite old.

How would this code look like for dispatch version 0.11.3?

Thanks!

Leonor
