HTTPBuilder set request contenttype

Question

I am using the following code to execute a HTTP POST towards an external system. The problem is that the external system always gets a 'null' content type when using the code below. Is there a way to set the contenttype when using HTTPBuilder.

I tried other tools that execute the same request but then the remote system gets a good contentType ('application/json').

 def execute(String baseUrl, String path, Map requestHeaders=[:], Map query=[:], method = Method.POST) { try { def http = new HTTPBuilder(baseUrl) def result = null // perform a ${method} request, expecting TEXT response http.request(method, ContentType.JSON) { uri.path = path uri.query = query // add possible headers requestHeaders.each { key, value -> headers."${key}" = "${value}" } // response handler for a success response code response.success = { resp, reader -> result = reader.getText() } } return result } catch (groovyx.net.http.HttpResponseException ex) { ex.printStackTrace() return null } catch (java.net.ConnectException ex) { ex.printStackTrace() return null } }

It seems you're doing it right. Is there a chance of your map parameter requestHeaders could be resetting Content-Type key? — Elias Dorneles

Nope, i removed the lines but still the remote system gets a 'null' as contentType — Marco

Adding a specific header to the request seems to solve my problem.

def execute(String baseUrl, String path, Map requestHeaders=[:], Map query=[:], method = Method.POST) { try { def http = new HTTPBuilder(baseUrl) def result = null // perform a ${method} request, expecting TEXT response http.request(method, ContentType.JSON) { uri.path = path uri.query = query headers.'Content-Type' = 'application/json' // add possible headers requestHeaders.each { key, value -> headers."${key}" = "${value}" } // response handler for a success response code response.success = { resp, reader -> result = reader.getText() } } return result } catch (groovyx.net.http.HttpResponseException ex) { ex.printStackTrace() return null } catch (java.net.ConnectException ex) { ex.printStackTrace() return null }

}

Try setting the requestContentType in the body of your request block...

http.request(method, ContentType.JSON) { uri.path = path uri.query = query requestContentType = groovyx.net.http.ContentType.URLENC ....... }

I tried your suggestion but still giving me 'null' on the receiver side.
