I am trying to implement a simple server in PyObjC for the Criollo HTTP server.
The server has a method to set route handlers by passing a block to setup the
route and then when it receives and HTTP request for the route it calls the
block. The block has the signature:
typedef void(^CRRouteBlock)(CRRequest* _Nonnull request, CRResponse* _Nonnull
response, CRRouteCompletionBlock _Nonnull completionHandler);
So, here is my simple proof of concept:
import objc
CRApplication = objc.lookUpClass("CRApplication")
global server
def helloHandler(self, request, response, handler):
response.send_("Hello World!")
handler()
if __name__ == "__main__":
server = CRApplication.sharedApplication().delegate().server()
server.get_block_("/", objc.selector(helloHandler,
signature=b'v@:@@@‘)) *** error occurs here
server.startListening()
But, when I try to setup the route I get the following error:
Traceback (most recent call last):
File "main.py", line 21, in <module>
server.get_block_("/", objc.selector(helloHandler, signature=b'v@:@@'))
TypeError: Argument 3 is a block, but no signature available
Any ideas how to workaround this issue and implement the route handlers in
PyObjC?
