一.python中jsonschma庫

python中有時候我們想對json數據進行鍵值對（key，value）數據的數據格式進行校驗，因為數據類型不符合業務邏輯會導致業務邏輯代碼執行報錯，這時候我們可以對傳入的json數據格式定義一個schema，定義數據模式，然后通過schema對data進行校驗，python中我們進行進行如下校驗：

# _*_ coding: utf-8 _*_ # !/usr/bin/pythonimport jsonschemaschema = {"type": "object","properties": {"version_no": {"type": "string"},"versions": {"type": "array","minItems": 1,"items": {"type": "object","required": ["name", "type"],"properties": {"name": {"type": "string","minLength": 1},"type": {"type": "string","enum": ["python", "java"]},"size": {"type": "number",},}}},},"required": ["version_no", "versions"] }data = {"version_no": "x123","versions": [{"name": "jack","type": "python","size": 123},{"name": "will","type": "java",}] }def schema_check(data, schema):try:jsonschema.validate(data, schema)print("data中數據通過自定義的json schema校驗")except jsonschema.exceptions.ValidationError as e:print(e.message, "data數據沒有通過schema格式校驗")schema_check(data, schema)輸出結果： 'php' is not one of ['python', 'java'] data數據沒有通過schema格式校驗 Process finished with exit code 0
