[flask] red map for module splitting

Introduction

Redprint, as the name suggests - Redprint.Blueprints are module-level splits, they're not designed to let you split up functions.To achieve a more specific split of view functions than at the module level, for example, when using Flask to create a REST API, when splitting according to the functions of different business objects under the version number, we need to customize a module with the same function as the blueprint.Here, in order to reflect the similarities and purposes of the blueprint, we named it the red map!

use

To implement Redprint, mainly refer to the source code/principle of blueprint to make some transformations redprint.pyfile

class Redprint:def __init__(self, name):self.name = nameself.mound = []def route(self, rule, **options):def decorator(f):self.mound.append((f, rule, options))return freturn decoratordef register(self, bp, url_prefix=None):if url_prefix is ​​None:url_prefix = '/' + self.namefor f, rule, options in self.mound:endpoint = options.pop("endpoint", f.__name__)bp.add_url_rule(url_prefix + rule, endpoint, f, **options)

Define red map

from app.utils.redprint import RedprintredApi = Redprint('api')

1. Register red image

from app.v1.api import redApicmsBlue = Blueprint('api_v1', __name__, template_folder='templates')redApi.register(cmsBlue, url_prefix='api')
