![]() ![]() ![]() Happily succeeds in handing us back a 403 Forbidden when we don’t send theĬSRF data - thus if our authApp were after it, we’d never reach it. Tokens! Because we’ve added Middleware.csrfValidate() to zApp, that portion We have to add authApp before zApp, or our basic auth route won’t beĪvailable! Why is that? It’s because we aren’t sending in any CSRF validation basicAuth ( "hooty", "tootie" ) val combined : Http = app ++ authApp ++ zApp If you’re already using the Apache HttpClient library for other purposes, this is a viable alternative.Package import zhttp.http._ import import zio._ object OwlServer extends ZIOAppDefault Middleware. This requires significantly more code than the omURL approaches, as well as the HttpClient library. tConnectionTimeout(httpParams, connectionTimeout) Private def buildHttpClient(connectionTimeout: Int, socketTimeout: Int): Val httpResponse = httpClient.execute(new HttpGet(url))Ĭontent = io.omInputStream(inputStream).getLines.mkString Val httpClient = buildHttpClient(connectionTimeout, socketTimeout) * socketTimeout The socket timeout, in ms. * connectionTimeout The connection timeout, in ms. * This function will also throw exceptions if there are problems trying * Returns a blank String if there was a problem. Before I learned about the previous approaches, I wrote a getRestContent method using this library like this: Using the Apache HttpClientĪnother approach you can take is to use the Apache HttpClient library. I haven’t tested this method with other request types, such as PUT or DELETE, but I have allowed for this possibility by making the requestMethod an optional parameter. If (inputStream != null) inputStream.closeĪs the Scaladoc shows, this method can be called in a variety of ways, including this:Ĭase ioe: java.io.IOException => // handle thisĬase ste: => // handle this Val content = io.omInputStream(inputStream).mkString Val inputStream = connection.getInputStream Val connection = (new URL(url)).openConnection.asInstanceOfĬtConnectTimeout(connectTimeout)ĬtRequestMethod(requestMethod) * readTimeout If the timeout expires before there is data available Scala versions: 2.11 2.12 2.13 3.x 679 68 22 zio/zio-http A next-generation Scala framework for building scalable, correct, and efficient HTTP clients and servers Scala versions: 2.12 2.13 3. A timeout of zero is interpreted as an infinite timeout. A Scala port of the popular Python Requests HTTP client: flexible, intuitive, and straightforward to use. ![]() If the timeout expires before the connection can * to be used when opening a communications link to the resource referenced * connectTimeout Sets a specified timeout value, in milliseconds, * The `connectTimeout` and `readTimeout` comes from the Java URLConnection * Returns the text (content) from a REST URL as a String. By using a combination of classes and the io.omInputStream method, you can create a more robust method that lets you control both the connection and read timeout values: Therefore, a better approach is to write a similar method that allows the setting of a timeout value. If the web service you’re calling isn’t responding, your code will become unresponsive at this point as well. As a result, you may want to annotate your method to indicate get(url: String): String = io.omURL(url).mkString Setting the timeout while using scala.io.omURLĪs mentioned, that simple solution suffers from a significant problem: it doesn’t time out if the URL you’re calling is unresponsive. Under the covers, the omURL method uses classes like and java.io.InputStream, so this method can throw exceptions that extend from java.io.IOException. You can use it to download web pages, RSS feeds, or any other content using an HTTP GET request. This GET request method lets you call the given RESTful URL to retrieve its content. to proxy requests the HTTP client should be configured to use an HTTP Proxy. * Warning: This method does not time out when the service is non-responsive.ĭef get(url: String): String = scala.io.omURL(url).mkString MockServer enables easy mocking of any system you integrate with via HTTP or. * Returns the text (content) from a URL as a String. If it doesn’t matter that your web service client won’t time out in a controlled manner, you can use this simple method to download the contents from a URL: These solutions are demonstrated in the following sections.
