nameko http 微服务运行失败，cyphon 编译 pyd 文件但 py 文件很好

Question

我开发了一个nameko http微服务，可以正常运行，但是如果我把文件myhttp.py替换成cyphon编译的文件myhttp.py，就会得到[curl: (7) Failed to connect to localhost端口 8000：连接被拒绝]，请帮帮我。

第一步：使用以下3个文件（build.bat,setup.py,myhttp.py）生成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,
)

我的http.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))
    
    

第二步：使用下面3个文件（installer.bat、namekorun.py、namekorun.spec）和刚才生成的myhttp.pyd生成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

                 hiddenimports=partylibs,
                 hookspath=[],
                 hooksconfig={},
                 runtime_hooks=[],
                 excludes=[],
                 win_no_prefer_redirects=False,
                 win_private_assemblies=False,

    pyz = PYZ(a.pure, a.zipped_data,
                 cipher=block_cipher)
    
    exe = EXE(pyz,
              a.scripts, 
              [],
              exclude_binaries=True,
              name='namekorun',
              debug=False,
              bootloader_ignore_signals=False,
              strip=False,
              upx=True,
              console=True,
              disable_windowed_traceback=False,
              target_arch=None,
              codesign_identity=None,
              entitlements_file=None )
    coll = COLLECT(exe,
                   a.binaries,
                   a.zipfiles,
                   a.datas, 
                   strip=False,
                   upx=True,
                   upx_exclude=[],
                   name='namekorun')
           

第 3 步：启动 dist/namekorun/namekorun.exe，然后在命令中输入 curl -i -d "world" localhost:8000/hello 窗口，并得到 curl: (7) 无法连接到localhost 8000端口：连接被拒绝，如果用myhttp.py替换myhttp.pyd，它运行良好

我的包如下，使用 vs2015

python	3.6.8
Cython	3.0.0a9
decorator	4.4.2
eventlet	0.25.1

pyinstaller	4.7

Answer 1

追溯nameko.web.handlers.http的定义：

• https://github.com/nameko/nameko/blob/17ecee2bcfa90cb0f3a2f3328c5004f48e4e02a3/nameko/web/handlers.py#L105,
• https://github.com/nameko/nameko/blob/b0862d7f390f4e58f6de847305ad07a48ce127ae/nameko/extensions.py#L312,
• https://github.com/nameko/nameko/blob/b0862d7f390f4e58f6de847305ad07a48ce127ae/nameko/extensions.py#L249-L256

setattr(fn, ENTRYPOINT_EXTENSIONS_ATTR, descriptors)

本质上它是在尝试在函数对象上设置属性。 Cython 函数是与常规 Python 函数不同的类，并且该类没有实例字典，因此 setattr 将失败（我有点惊讶您没有收到明显的错误）。

因此，我不希望使用 Cython 编译此代码。
