python-Django项目通过编译为.pyc-形式发布

python Django项目通过编译为.pyc 形式发布：

一、批量编译代码

创建compile_pyc.py，代码如下：

import os
import sys
import shutil
from py_compile import compile

def clean(path):
    for parent, dirname, filename in os.walk(path):
        for dir in dirname:
            if dir == '__pycache__':
                try:
                    fullname = os.path.join(parent, dir)
                    shutil.rmtree(fullname)
                    print("Success clean Folder:%s" % fullname)
                except Exception as e:
                    print("Can't clean Folder:%s, reason:%s" % (fullname, e))

def compile_pyc(path):
    for parent, dirname, filename in os.walk(path):
        for cfile in filename:
            fullname = os.path.join(parent, cfile)
            if cfile[-3:] == '.py':
                try:
                    if compile(fullname):
                        if cfile != 'settings.py' and cfile != 'wsgi.py':
                            os.remove(fullname) #删除原文件，保留settings.py和wsgi.py
                        print("Success compile and remove file:%s" % fullname)
                    else:
                        print("Can't compile file:%s,The original file has been retained" % fullname)
                except Exception as e:
                    print("Can't compile file:%s, reason:%s" % (fullname, e))

def move(path):
    for parent, dirname, filename in os.walk(path):
        for c_file in filename:
            fullname = os.path.join(parent, c_file)
            if c_file[-4:] == '.pyc':
                try:
                    parent_path = os.path.dirname(parent)
                    shutil.move(fullname, parent_path)
                    print('update the dir of file successfully')
                except Exception as e:
                    print("Can't move file:%s, reason:%s" % (fullname, e))

def replace_name(path):
    for parent, dirname, filename in os.walk(path):
        for c_file in filename:
            fullname = os.path.join(parent, c_file)
            if c_file[-4:] == '.pyc':
                try:
                    cfile_name = ''
                    cfile_list = c_file.split('.')
                    version = sys.version_info
                    replace_name = 'cpython-' + str(version[0])+str(version[1])
                    for i in range(len(cfile_list)):
                        if cfile_list[i] == replace_name:
                            continue
                        cfile_name += cfile_list[i]
                        if i == len(cfile_list) - 1:
                            continue
                        cfile_name += '.'
                    shutil.move(fullname, os.path.join(parent, cfile_name))
                    print('update the name of the file successfully')
                except Exception as e:
                    print("Can't remove file:%s, reason:%s" % (fullname, e))

if __name__ == '__main__':
    if len(sys.argv) == 3:
        cmd = sys.argv[1]
        path = sys.argv[2]
        if os.path.exists(path) and os.path.isdir(path):
            if cmd == 'clean':
                clean(path)
            elif cmd == 'move':
                move(path)
            elif cmd == 'replace_name':
                replace_name(path)
            elif cmd == 'compile_pyc':
                compile_pyc(path)
            elif cmd == 'compile':
                clean(path)
                compile_pyc(path)
                move(path)
                replace_name(path)
                clean(path)
            else:
                print('没有该命令')
        else:
            print("Not an directory or Direcotry doesn't exist!")
    else:
        print("在命令行中使用以下命令:")
        print("\tpython3 compile_pyc.py compile_pyc PATH\t\t#生成pyc文件")
        print("\tpython3 compile_pyc.py move PATH\t\t#移动所有pyc文件至原位置")
        print("\tpython3 compile_pyc.py replace_name PATH\t\t#修改文件名文件")
        print("\tpython3 compile_pyc.py clean PATH\t\t#清除当前项目中所有的__pycache__文件夹及以内文件")
        print("\tpython3 compile_pyc.py compile PATH\t\t#一键编译pyc")

二、运行命令

逐步运行以下命令

python3 compile_pyc.py clean <PATH> #清除当前项目中所有的__pycache__文件夹及以内文件
python3 compile_pyc.py compile_pyc <PATH> #生成.pyc文件，并删除源文件
python3 compile_pyc.py move <PATH> #将.pyc文件移动到原py文件目录下
python3 compile_pyc.py replace_name <PATH> #去掉.pyc文件名中的版本号
python3 compile_pyc.py clean <PATH>

或者直接运行以下一条命令就可以

python3 compile_pyc.py compile <PATH>

三、注意

保留了settings.py和wsgi.py这两个文件，方便改变配置，以及之后的uwsgi部署

多次运行，.pyc会移动错乱，保证只移动在__pycache__下的.pyc文件，修改move代码

def move(path):
    for parent, dirname, filename in os.walk(path):
        for c_file in filename:
            fullname = os.path.join(parent, c_file)
            if os.path.basename(parent) == '__pycache__':
                if c_file[-4:] == '.pyc':
                    try:
                        parent_path = os.path.dirname(parent)
                        shutil.move(fullname, parent_path)
                        print('update the dir of file successfully')
                    except Exception as e:
                        print("Can't move file:%s, reason:%s" % (fullname, e))
