A popular Kotlin web framework got rid of some annoying communication bugs with the release of Ktor 2.2.4 making API requsts more developer friendly

Ktor is a popular Kotlin based web framework that makes it possible to build a connected application with minimal effort. Ktor is an asynchronous framework for building web apps, microservices, and other things. But even the most robust software can fall victim to bugs, which is why the Ktor development team has recently rolled out a series of bug fixes designed to enhance the framework’s functionality and improve user experience. Let’s take a closer look at some of the recent bug fixes.

🏪 Improved URL Parsing For HTTP Client Requests

Using an underscore in the request URL with Ktor HTTP client would fail the request. Upon calling toURI() or URLBuilder() method, it fails to parse the port and hostname correctly. If you frequently use docker, then you might have come across this bug as hostnames with an underscore are quite common in the docker environments. After the latest release, you can now use the URLs with the underscore without having any issues.

Read to the end for an awesome bonus!

🪲 Wrong Content-Type Now Results In 415 Status Code

Previously, having a wrong content type would result in Error 405, but the problem is the that error should be 415 instead. Error 405 indicates that the server knows the request method, but the target resource doesn’t support this method. But in this scenario, the error should be 415, which indicates that the server refuses to accept the request because the payload format is in unsupported format. After the lasted bug fixes, you will get a correct error message upon entering the wrong content type in the route.

💎 Forceful Addition Of “charset=UTF-8” In Content-Type Header Resolved

While working with HTTPClient, the Accept-Charset: UTF-8 gets added in a request automatically, if you don’t add any Accept-Charset header. This can cause a problem because Web Application Firewalls with newer standards, refuse requests that contain Accept-Charset. This issue has been resolved according to the latest bug fixes.
