Hi guys,
I want to use only one HttpClient to request multiple hosts. I use type-safe requests
@Resource("https://example.com/articles")
class Articles()

but the result request URL will be HTTP://localhos/https:<//example.com/articles>.
I saw https://youtrack.jetbrains.com/issue/KTOR-5586 fixed, but not for resources, only plain request.

The Resource annotation accepts a path, not a full URL. You can use the DefaultRequest plugin to set the default URL for all requests.

Thanks @Aleksei Tirman [JB] , how can I use 1 http client for multiple resources from mutiple host names. without Resource I can do it.

[Aleksei Tirman [JB]]

You can configure HttpRequestBuilder for each request to set the appropriate host. Here is an example:

@Resource("/get")
class Get()

suspend fun main() {
    val client = HttpClient(CIO) {
        install(Resources)
    }

    val response =  client.get(Get()) {
        url {
            protocol = URLProtocol.HTTPS
            host = "httpbin.org"
        }
    }

    println(response.bodyAsText())
}

I missed this one. I still have a small concern that I need to explicit specify the host ( which I believe is not “type-safe”. I can set a wrong host or forget to set host).
I still go with your suggestion. Thank you a lot for your help.
