Python利用第三方模块实现压缩css文件

from csscompressor import compress

# 你需要压缩的 CSS 文件路径
css_file = '../flask_demo_learn/static/base.css'

# 读取 CSS 文件
with open(css_file, 'r',encoding='utf-8') as file:
    css = file.read()

print(css)
# 压缩 CSS 代码
compressed_css = compress(css)

# 将压缩后的 CSS 代码写入新的文件
with open(css_file, 'w') as file:
    file.write(compressed_css)

@app.route('/compress-css')
def compress_css():
    # 你需要压缩的 CSS 文件路径
    css_file = 'static/base_bak.css'

    # 读取 CSS 文件
    with open(css_file, 'r', encoding='utf-8') as file:
        css = file.read()

    # 压缩 CSS 代码
    compressed_css = css_compress(css)

    # 返回压缩后的 CSS 代码
    return Response(compressed_css, mimetype='text/css')


if __name__ == '__main__':
    app.run()

<link rel="stylesheet" type="text/css" href="{{ url_for('compress_css') }}" />

# 删除注释
compressed_css = compress(css, preserve_exclamation_comments=True)
print(compressed_css)

pip install cssmin

from cssmin import cssmin

# 你需要压缩的 CSS 文件路径
css_file = '../flask_demo_learn/static/base_bak.css'

# 读取 CSS 文件
with open(css_file, 'r', encoding='utf-8') as file:
    css = file.read()

# 压缩 CSS 代码

compressed_css = cssmin(css)
print(compressed_css)

pip install rcssmin

import rcssmin
# 你需要压缩的 CSS 文件路径
css_file = '../flask_demo_learn/static/base_bak.css'

# 读取 CSS 文件
with open(css_file, 'r', encoding='utf-8') as file:
    css = file.read()

# 压缩 CSS 代码

compressed_css = rcssmin.cssmin(css)
print(compressed_css)
