i know you shouldn't send a HTTP GET Request with a body, but ceilometer web api forces me to do so. I'm developing a ceilometer scala client, so I need a scala/java way to make a get request with a body. So far I tried with beeClient (http://www.bigbeeconsultants.co.uk) and in plain Java using httpConnection but I get a 404 error. In curl I can achieve the result in this way:
curl -X GET -H "X-Auth-Token: ..long long token here.."
-H "Content-Type: application/json"
-d '{"q": [{"field": "resource", "op": "eq", "value": "gdfsf"}]}'
http://137.204.57.150:8777/v2/meters/
That's my scala code that uses java HttpURLConnection:
import java.io._
import java.net._
val token = "myToken"
val url = new URL("http://137.204.57.150:8777/v2/meters/")
val body = "{\"q\": [{\"field\": \"resource\", \"op\": \"eq\", \"value\": \"gdfsf\"}]}"
val bodyLenght = body.length.toString
val connection = url.openConnection().asInstanceOf[HttpURLConnection]
connection.setRequestMethod("GET")
connection.setRequestProperty("Content-Type", "application/json")
connection.setRequestProperty("Content-Length", bodyLength)
connection.setRequestProperty("Accept", "*/*")
connection.setRequestProperty("X-Auth-Token", token)
connection.setDoInput(true)
connection.setDoOutput(true)
//SEND REQUEST
val wr = new DataOutputStream(connection.getOutputStream)
wr.write(body.getBytes)
wr.flush
wr.close
if (connection.getResponseCode == 200)
println("ok")
else
println("error")
What's the difference between my Java implementation and the curl command? I can't see any, I tried checking the header of curl calling it with the -v argument and that's what I get:
* Hostname was NOT found in DNS cache
* Trying 137.204.57.150...
* Connected to 137.204.57.150 (137.204.57.150) port 8777 (#0)
> GET /v2/meters/ HTTP/1.1
> User-Agent: curl/7.37.1
> Host: 137.204.57.150:8777
> Accept: */*
> X-Auth-Token: ...Token....
> Content-Type: application/json
> Content-Length: 60
>
* upload completely sent off: 60 out of 60 bytes
* HTTP 1.0, assume close after body
And then I get the response.
Thank you in advance
I resolved the problem using jetty-client implementation, that lets build http requests in anyway you want. Here's the code (it's not immutable but it's not that bad in scala):
val httpClient = new HttpClient()
httpClient.setConnectTimeout(connectTimeout)
httpClient.setFollowRedirects(false)
httpClient.setStopTimeout(readTimeout)
httpClient.start()
val resp = httpClient.newRequest(uri).
method(HttpMethod.GET).
header("X-Auth-Token",s).
send()
Look that i'm using the blocking API but jetty provides also a Java NIO API.
