Flask框架學習筆記（API接口管理平台 V1.0）

今天博主終於完成了API接口管理平台，最后差的就是數據庫的維護，

博主這里介紹下平台的設計原理，首先基於python，利用flask的web框架+bootstrap前端框架完成，先階段完成了前台展示頁

二期要加入登錄退出，后台管理

下面是文檔結構圖

涉及的python第三方模塊：flask、flask-bootstrap、sqlalchemy

整體頁面的布局：頁頭的導航，右側的API分類，頁面信息

頁面信息內容包括：接口說明，請求參數，返回參數，請求示例，返回示例

下面是定義數據庫對象的model.py 文件

#!/usr/bin/env python
# -*- coding: utf-8 -*-


from sqlalchemy import Column, create_engine
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
import json
import sys
# 導入數據庫所有表字段類型
from sqlalchemy.dialects.mysql import \
    BIGINT, BINARY, BIT, BLOB, BOOLEAN, CHAR, DATE, \
    DATETIME, DECIMAL, DECIMAL, DOUBLE, ENUM, FLOAT, INTEGER, \
    LONGBLOB, LONGTEXT, MEDIUMBLOB, MEDIUMINT, MEDIUMTEXT, NCHAR, \
    NUMERIC, NVARCHAR, REAL, SET, SMALLINT, TEXT, TIME, TIMESTAMP, \
    TINYBLOB, TINYINT, TINYTEXT, VARBINARY, VARCHAR, YEAR

# 創建對象的基類:
Base = declarative_base()

reload(sys)
sys.setdefaultencoding("utf-8")


# 定義api表對象
class Api(Base):
    # 表的名字:
    __tablename__ = 'api'

    # 表的結構:
    id = Column(INTEGER(10), primary_key=True)
    name = Column(VARCHAR(50))
    url = Column(TEXT)
    method = Column(VARCHAR(10))
    service = Column(VARCHAR(50))
    access_token = Column(VARCHAR(255))
    reqParam = Column(TEXT)
    response = Column(TEXT)
    requestExam = Column(TEXT)
    responseExam = Column(TEXT)


# 定義model表對象
class Model(Base):
    # 表的名字:
    __tablename__ = 'model'

    # 表的結構:
    id = Column(VARCHAR(25), primary_key=True)
    name = Column(VARCHAR(50))
    ch_name = Column(VARCHAR(50))
    from_id = Column(VARCHAR(25))

下面是試圖views.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

博主根據路由對首頁，模塊，接口 定義了視圖

最后給大家看下效果
