HttpClientを作ってScalaの練習

How to build

Just run ant, then copy and paste jar file to your classpath. Ivy is needed to resolve dependencies.

Dependencies

All libraries are used to execute unit test.

• scalatest
• junit
• commons-codec

Created jar is executable without any dependencies.

How to use

Just import com.shc.http:

import com.shc.http._

Here is a simple GET request. This returns request.Response instance obj:

val url = "http://example.com"
var resp = Request.get(url)

If you want to add query strings, just pass key-value map to the method:

resp = Request.get(url, Map("name" -> "foofoo"))

How to retrieve response contents:

if(resp != None){
  val url = resp.get.url // java.net.URL
  val statusCode = resp.get.statusCode // String
  val headers = resp.get.headers // Map[String, List[String]]
  val message = resp.get.message // String
  val cookies = resp.get.cookies // List[java.net.HttpCookie]
}

Uploading files:

val files = Map("key" -> "/where/the/file/exist")
resp = Request.post(url, files = files)
resp = Request.post(url, Map("key" -> "value"), files)

Creating authentication credential. This support basic & digest auth:

if(resp != None & resp.get.statusCode == 401){
  resp = Request.get(url, auth = resp.auth("user", "pass"))
  println(resp.get.statusCode == 200)
}

Reusing cookieManager:

val cookies = resp.cookies.foreach(println)
val cookieManager = resp.cookieManager
resp = Request.get(url, cookie = cookieManager)

Storing contents:

val path = "/path/to/somewhere"
val bool = resp.store(path)
println(bool)
