Request handler for a function in Kotlin
A request handler is a method used to process each Kotlin function call. Here is an example of a script with the handle
method acting as a handler:
data class Response(
val statusCode: Int,
val body: String
)
fun handle(request: String): Response {
return Response(200, request)
}
The script processes an incoming HTTP request and outputs its structure and HTTP response code. The script uses a top-level function as the programming model in Kotlin.
When creating a function version, you specify the entry point, i.e., the function that the runtime environment calls as a handler. The entry point name depends on the programming model being used:
-
For a top-level fuction:
<package_name>.<handler_file_name>::<handler_method_name>
, e.g.,somepackage.Handler::handle_http
.When naming the entry point, specify the file name without its extension.
If your method is
handle
, you may skip it. -
For the YcFunction interface:
<package_name>.<class_name>
, e.g.,somepackage.Handler
.
The name of the handler file must contain no .
before the extension, e.g., .Handler.kt
.
Note
At any given time, a single function instance processes only one request. This allows you to use global variables without having to provide data integrity control.
