使用cython把python编译so

1.需求

为了保证线上代码安全和效率，使用python编写代码，pyc可直接反编译，于是把重要代码编译so文件

2.工作

2.1 安装相关库：

pip install cython

yum install -y gcc python-devel

2.2 创建setup.py

#!/usr/bin/env python

# coding=utf-8

from distutils.core import setup

from Cython.Build import cythonize

setup(

    ext_modules = cythonize("xxxx.py")

)

2.3 运行

root@868aec72d1a4:/xxx/xxx/xxx# python setup.py build_ext

Compiling xxx.py because it changed.

[1/1] Cythonizing xxx.py

running build_ext

building 'lib.xxx' extension

creating build

creating build/temp.linux-x86_64-2.7

x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fno-strict-aliasing -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -fPIC -I/usr/include/python2.7 -c xxx.c -o build/temp.linux-x86_64-2.7/xxx.o

creating build/lib.linux-x86_64-2.7

creating build/lib.linux-x86_64-2.7/lib

x86_64-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions -Wl,-z,relro -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wl,-Bsymbolic-functions -Wl,-z,relro -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security build/temp.linux-x86_64-2.7/xxx.o -o build/lib.linux-x86_64-2.7/lib/xxx.so

会在当年目录上传build目录，结构如下：

root@868aec72d1a4:/spider/codes/lib# tree build/

build/

|-- lib.linux-x86_64-2.7

|   `-- lib

|       `-- xxx.so

`-- temp.linux-x86_64-2.7

    `-- xxx.o

3 directories, 2 files

2.4 获取so文件即可
