获取 Django 项目下全部 URL，一个函数轻松搞定

    if resolver is None:

    for r in resolver.url_patterns:

        if isinstance(r, URLResolver):
            yield from get_all_url(r, pre + str(r.pattern))
if __name__ == '__main__':
    # 获取项目全部 url
    for url, name in get_all_url():
        print("url='{}'  name='{}'".format(url, name))
    # 获取某个 app 下的全部 url
    # 假设有一个 app 叫 dashboard
    # 通过 pre 参数传入相应前缀
    for url, name in get_all_url(get_resolver('dashboard.urls')):
