python web開發(fā)中對大量參數的校驗（返回自定義錯誤提示）

安裝schema

pip install schema

校驗創(chuàng)建賬號的參數

• name: string 由7—15個字母捷沸、數字伊群、下劃線組成
• phone: string 11位手機號
• education: int 1:primary school; 2: junior high school; 3: High school; 4: bachelor; 5: master; 6: doctor
• age: int [7-150] 可選
• level: high脐供、middle治专、low
• grade: int 可選

校驗示例（可直接運行）

我的運行環(huán)境：
python: 3.7.1
schema: 0.6.8

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