Hello everyone ! I have a problem adding path to my request with my ktor client. This is my code:

// Definition of my client
val client = HttpClient {
 ...
  defaultRequest {
    url {
        takeFrom("<http://localhost:8080>")
        appendPathSegments("v1")
    }
   }
}

// Example of request
<http://client.post|client.post> {
  url {
    appendPathSegments("test", "test2)
  }
}

With this code, the client will request:

<http://localhost:8080/test/test2>

and not

<http://localhost:8080/v1/test/test2>

However, if in the client definition, instead of

v1

I put

/v1/

, the client will request

<http://localhost:8080/v1/test/test2>

as expected Do you know why I have this behavior and how to fix it ?

If your basepath ends with / and your request starts with no slash it will append it else if your request starts with a slash it will start from the host. If your basepath does not end with a slash it will always start every request from the host. e.g: base.com/v1 , start -> base.com/start base.com/v1/ , start -> base.com/v1/start base.com/v1/ , /start -> base.com/start

So in my code, how can I define the basePath always as

<http://localhost:8080/v1>

for all requests ? (instead of put

/v1/

in add path)

defaultRequest {
        url("<http://localhost:8080/v1/>" )
    }

No you need the trailling slash

hum ok I will try
