[groovy-user] Groovy : REST Example ( HTTP Builder )

[Parth Vora]

Hello All,

 

I am trying to use a HTTP builder to automate a simple rest call.

 

I keep getting MissingMethodException.

 

My REST Query is as follows :

 

URL : someurl

Headers : h1:value1, h2:value2

Method : GET

 

I don’t know what to import. Can someone help ?

 

For now I am using :

import static groovyx.net.http.Method.GET

import static groovyx.net.http.ContentType.TEXT

import groovyx.net.http.HTTPBuilder

 

Am  I missing something ?

 

-Thanks,

Parth.

Hello Parth,

Could you show your example code?

Here is an example using HttpBuilder:

Hello,

Here you go..

import static groovyx.net.http.Method.GET
import static groovyx.net.http.ContentType.TEXT
import groovyx.net.http.HTTPBuilder

def http = new HTTPBuilder('http://URL')
ERROR is caught here --> http.request( Method.GET, ContentType.TEXT ) { req ->
uri.path = '/some-path'
headers.Accept = 'application/json'
headers.ClientRoles = 'ROLES'

response.success = { resp, reader ->
println "Got response: ${resp.statusLine}"
println "Content-Type: ${resp.headers.'Content-Type'}"
print reader.text
}
}

This is due to incorrect use/understanding of "import static..."

Once you have done:

import static groovyx.net.http.Method.GET

You only need to use:

GET

NOT:

Method.GET

See:

http://docs.oracle.com/javase/1.5.0/docs/guide/language/static-import.html

Thanks Bob. I got that.

I tried this but all in vain I still get the same error.

import groovyx.net.http.HTTPBuilder
importstatic groovyx.net.http.Method.GET
importstatic groovyx.net.http.ContentType.JSON

def http = new HTTPBuilder( 'URL' )
http.request( GET, JSON ) {
uri.path = '/somepathURL'
headers.Accept = 'application/json'
headers.ClientRoles = 'ROLE'
headers.Authorization = 'AuthToken'

response.success = { resp, json ->

println "Got response: ${resp.statusLine}"
println "Content-Type: ${resp.headers.'Content-Type'}"
print reader.text
}
}

This works for me with Groovy 2.1.4:

---
@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.6' )

import groovyx.net.http.HTTPBuilder
import static groovyx.net.http.Method.GET
import static groovyx.net.http.ContentType.JSON

new HTTPBuilder().request('http://baseballipsum.apphb.com/api/?paras=1&startwithlorem=true', GET, JSON ) {
// headers don't do anything useful in this example...

headers.Accept = 'application/json'
headers.ClientRoles = 'ROLE'
headers.Authorization = 'AuthToken'

//

response.success = { resp, reader ->
println "Got response: ${resp.statusLine}"
println "Content-Type: ${resp.headers.'Content-Type'}"

println reader
}
}
---

Note that the use of 'reader' is slightly different from what is given in the doco at: http://groovy.codehaus.org/modules/http-builder/doc/get.html
Note also that there are easier ways of doing a GET than using the response() method.

Hello Bob,

Can you send me the snap shot of your pom file where you have mentioned your groovy version ?

I can replicate that and try re-running it !

-Thanks,
Parth.

[Bob Brown]

The script will run as-is. Just copy it into the groovy console and run it.
