影响我写文档的原因可能是代码和文档分离，有时候写完代码会忘记补文档，而且不能及时查看，使用 Flask-Docs 可以解决我的问题，这个插件可以根据代码注释生成文档页面，代码注释改动文档可以及时更新，而且支持离线文档下载。

Flask-Docs

Flask Api 文档自动生成插件

特性

• 根据代码注释自动生成文档
• 支持 Flask-RESTful
• 支持离线 markdown 文档下载

安装

pip install Flask-Docs

使用

from flask import Flask
from flask_docs import ApiDoc

app = Flask(__name__)

# 本地加载
# app.config['API_DOC_CDN'] = False

# 禁用文档页面
# app.config['API_DOC_ENABLE'] = False

# 需要显示文档的 Api
app.config['API_DOC_MEMBER'] = ['api', 'platform']

# 需要排除的 RESTful Api 文档
app.config['RESTFUL_API_DOC_EXCLUDE'] = []

ApiDoc(app)
