As a quick note, I just found this getUrlInputStream
method in an old Scala project. It needs to be updated and cleaned-up, but if you are looking for some code to get you started with opening a URL as an InputStream in Scala, this may be helpful:
/** * See http://alvinalexander.com/blog/post/java/how-open-url-read-contents-httpurl-connection-java * * Note that this can throw a java.net.UnknownHostException * */ def getUrlInputStream(url: String, connectTimeout: Int = 5000, readTimeout: Int = 5000, requestMethod: String = "GET") = { val u = new URL(url) val conn = u.openConnection.asInstanceOf[HttpURLConnection] HttpURLConnection.setFollowRedirects(false) conn.setConnectTimeout(connectTimeout) conn.setReadTimeout(readTimeout) conn.setRequestMethod(requestMethod) conn.connect conn.getInputStream }
Again, the code isn’t great, but it can serve as a starter if you need some code to read from a URL as an input stream in Scala.
