Hi - does anyone know how to set the basePath value in either OpenApi2 or OpenApi3? Without this the links in our swagger documentation are unable to be executed. We are currently using http4k v. 3.154.0. thanks.

The basepath should be automatically picked up by how the handler is bound. Check out the full example test and let us know if you still have problems working it out: https://github.com/http4k/http4k/blob/master/http4k-contract/src/test/kotlin/org/http4k/contract/ContractRendererContract.kt

@dave the problem is I don’t actually want to change the url as such, I only want it to be changed in the documentation i.e. the link that gets executed when a user tries to test an endpoint. The problem is we have proxies in front of our service that requests are routed to so our urls are prefixed with this information e.g.

/routing1/routing2/my/actual/endpoint

so contract route is

/my/actual/endpoint

but the swagger generated link needs to be the full url with routing prefix. I can’t think of a way around this other than handcrafting the swagger.json at this point.

Does that mean your endpoints are available on 2 different URLs depending on the host you use?

No the routing, or what I am referring to as the “base path” (possibly incorrectly), will be the same regardless of host, except when running locally where there is no proxy, but I am less concerned about that at this stage

Am a little confused then. The entire basepath (other than hostname) should be present in the OpenApi docs if its bound at the correct place in the http4k app. In this case I'd expect you to be mounting the whole contract at "/routing1/routing2"
