Forcing trailing slash before query params with OkHttp3

Question

I have a String url with queries (https://example.com/path/segments?q1=1&q2=2 for example). I need to add trailing slash (https://example.com/path/segments/?q1=1&q2=2) before queries if it does not exist using okhttp 3. How can I do this?

Before using the string you could just do an replace on the ? and replace it with /? and you get the result you want.

Here's an example in Kotlin

var url:String = "https://example.com/path/segments?q1=1&q2=2"
url = url.replace("?", "/?")

This should work since the query variables should be urlencoded and there should only be one occurence of ? in your urls.

It will work, but I thought there is something better with [HttpUrl.Builder](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-http-url/-builder/) using – Alexey Nikitin Oct 28 '19 at 06:44

Use httpUrlBuilder.addPathSegment("") to force a trailing slash at the end of the path. HttpUrl models each path segment as being prefixed by a /, with an empty string indicating a lone slash.
