I develop a nameko http micro servie, and it can run well, but if I replace the file myhttp.py with a cyphon compiled file named myhttp.py, I will get [curl: (7) Failed to connect to localhost port 8000: Connection refused],please help me.
step 1: use the below 3 files(build.bat,setup.py,myhttp.py) to generate myhttp.pyd
build.bat
python setup.py build_ext --inplace
setup.py
from setuptools import setup
from Cython.Build import cythonize
setup(
name = 'myapp',
ext_modules=cythonize("myhttp.py"),
zip_safe=False,
)
myhttp.py
from nameko.web.handlers import http
import json
class MyHttpService:
name = 'my_http_service'
@http('POST','/hello') #curl -i -d "world" localhost:8000/hello
def hello(self, request):
return "Hello, {}!".format(request.get_data(as_text=True))
step 2: use the below 3 files(installer.bat, namekorun.py, namekorun.spec) and generated myhttp.pyd just now to generate namekorun.exe
installer.bat
pyinstaller --noconfirm namekorun.spec
namekorun.py
import eventlet;
eventlet.monkey_patch()
from nameko.runners import ServiceRunner
import myhttp
import signal
runner = ServiceRunner(config={'WEB_SERVER_ADDRESS': '0.0.0.0:8000'})
runner.add_service(myhttp.MyHttpService)
def shutdown(signum, frame):
# signal handlers are run by the MAINLOOP and cannot use eventlet
# primitives, so we have to call `stop` in a greenlet
eventlet.spawn_n(runner.stop)
signal.signal(signal.SIGTERM, shutdown)
runner.start()
runnlet = eventlet.spawn(runner.wait)
while True:
try:
runnlet.wait()
except OSError as exc:
if exc.errno == errno.EINTR:
# this is the OSError(4) caused by the signalhandler.
# ignore and go back to waiting on the runner
continue
raise
except KeyboardInterrupt:
print() # looks nicer with the ^C e.g. bash prints in the terminal
try:
runner.stop()
except KeyboardInterrupt:
print() # as above
runner.kill()
else:
# runner.wait completed
break
namekorun.spec
# -*- mode: python ; coding: utf-8 -*-

step 3: start dist/namekorun/namekorun.exe, then type curl -i -d "world" localhost:8000/hello in a command window, and got curl: (7) Failed to connect to localhost port 8000: Connection refused, if replace myhttp.pyd with myhttp.py, it run well
