How to create base HTTP request with common query parameters

[mike.pet...@gmail.com]

Hi. I am interested in defining a query parameter that will appear on every HTTP request that extends the trait where that query parameter is defined rather than added it individually on each simulation. How do I do that?

This would be similar to how Rest Assured allows you to merge RequestSpecifications in terms of the desired effect.

Thanks!

Sorry, I don't understand what you mean (mixing requests and simulations).

Could you please provide an example of what you're trying to achieve?

Hey Stephane. Where I am doing something like this where I am including uniqueCallId on each request,  I want to extend or merge an existing http request that already has uniqueCallId on it:

val search  =
exec(http("${entity}")
.get("${restURL}search/${entity}")
.header("BhRestToken", "${restToken}")
.queryParam("query", queryString)
.queryParam("count", 15)
.queryParam("uniqueCallId", uniqueCallId)
.check(status.is(200))
)

Hi Mike

You can try something like this


trait HttpSupport {


def getHttpConf(implicit httpParam:HttpParam): HttpProtocolBuilder = {
http
.baseUrl(httpParam.baseURL)
.acceptHeader("application/json")
.basicAuth(httpParam.userName, httpParam.password)
.header("Content-Type", "application/json")
.shareConnections
}

}

class <Simulation Name> extends Simulation  with HttpSupport  {

 val httpConf = getHttpConf

httpConf.queryParam()

......

......

......

Thanks. Is it possible to add HTTP query parameters in the HttpProtocol? I didn't think it was. Can you show an example of adding one?

[Sri Harsha G]

You can try adding that to the trait method getHttpConf... and pass the query param values are parameters to the method

Still not sure what you're trying to do, but:

• no, there's no way to define common queryParams on HttpProtocol
• you could create a method to create your requests, eg:

def makeRequest(name: String, url: String) =

  http(name).get(url).queryParam("foo", "bar")

Then

exec(makeRequest("name", "url").queryParam("baz", "qix"))

So far I haven't been able to get anything like the suggestion to work. Any other ideas? Maybe I am just misunderstanding and need a more explicit example.

 Here is the equivalent of what I want to do - in REST Assured:
spec
RequestSpecification spec(RequestSpecification requestSpecificationToMerge)

Add request data from a pre-defined specification. E.g. RequestSpecification requestSpec = new RequestSpecBuilder().addParam("parameter1", "value1").build(); given(). spec(requestSpec). param("parameter2", "value2"). when(). get("/something");

This is useful when you want to reuse an entire specification across multiple requests.

The following settings are merged:

• Parameters
• Cookies
• Headers
