如何解决仅打包cythonized二进制python文件和资源数据,但忽略python .py源文件
基于@hoefling的回答,我能够打包resource_folder并混淆了二进制a.so文件。
setup.py的配方
from Cython.distutils import build_ext
from Cython.Build import cythonize
from setuptools.extension import Extension
from setuptools.command.build_py import build_py as build_py_orig
from pathlib import Path
from setuptools import find_packages, setup, Command
import os
import shutil
here = os.path.abspath(os.path.dirname(__file__))
packages = find_packages(exclude=('tests',))
def get_package_files_in_directory(directory):
paths = []
for (path, directories, filenames) in os.walk(directory):
for filename in filenames:
paths.append(os.path.join('..', path, filename))
return paths
#to copy the __init__.py as specified in above references links
class MyBuildExt(build_ext):
def run(self):
build_ext.run(self)
build_dir = Path(self.build_lib)
root_dir = Path(__file__).parent
target_dir = build_dir if not self.inplace else root_dir
self.copy_file(Path('main_folder') / '__init__.py', root_dir, target_dir)
def copy_file(self, path, source_dir, destination_dir):
if not (source_dir / path).exists():
return
shutil.copyfile(str(source_dir / path), str(destination_dir / path))
#as specified by @hoefling to ignore .py and not resource_folder
class build_py(build_py_orig):
def build_packages(self):
pass
setup(
packages=find_packages(), # needed for obfuscation
ext_modules=cythonize(
[
Extension("main_folder.*", ["main_folder/*.py"])
],
build_dir="build",
compiler_directives=dict(
always_allow_keywords=True
)),
package_data={p: get_package_files_in_directory(os.path.join(here, p, 'resource_folder')) for p in packages}, #package_data as found in another reference
cmdclass={
'build_py': build_py
},
entry_points={
},
)
创建混淆的* .whl软件包命令集
python setup.py build_ext #creates the a.so
python setup.py build_py #copies the resource_folder excluding .py
python setup.py bdist_wheel # then whl generation
解决方法
我需要混淆我的python代码,要实现它,我正在使用cythonize扩展名,我能够实现它,并从a.py文件中获取二进制编译的a.so文件,但是在执行bdist_wheel之后,.whl包仅打包了a。因此归档并忽略resource_folder。
我的项目文件结构是
|main_project
|__,setup.py
|__,main_folder
|____,a.py
|____,__init__.py
|____resource_folder
|__,a.model
|__,a.json
我使用以下链接制作了模糊的python wheel包,

仅打包使用Cython编译的python库的二进制编译.so文件
以下是我的setup.py中的代码段
packages = find_packages(exclude=('tests',))
def get_package_files_in_directory(directory):
paths = []
for (path,directories,filenames) in os.walk(directory):
for filename in filenames:
paths.append(os.path.join('..',path,filename))
return paths
setup(
packages=[],ext_modules=cythonize(
[
Extension("main_folder.*",["main_folder/*.py"])
],build_dir="build",compiler_directives=dict(
always_allow_keywords=True
)),package_data={p: package_files + get_package_files_in_directory(os.path.join(here,p,'resources')) for p in packages},....,...
)
要打包我正在使用以下命令
python setup.py build_ext
python setup.py bdist_wheel
预期的结果是包含.so文件和资源文件夹的.whl文件
实际结果是.whl文件仅包含一个.so文件。
还要按照此链接“(如何将其他文件添加到车轮? ” )中的建议打包我使用的get_package_files_in_directory()函数的resource_folder,但这对我也不起作用
