python flask接口字段存在性校验函数（http接口字段校验）（返回提示缺少的字段信息）validate_fields()

字段存在性校验

from flask import Flask, request, jsonify

app = Flask(__name__)

def validate_fields(data, fields):
    missing_fields = [field for field in fields if field not in data]
    if missing_fields:
        return False, f"缺少以下字段: {', '.join(missing_fields)}"
    return True, "所有字段都存在"

@app.route('/your_endpoint', methods=['POST'])
def handle_request():
    data = request.get_json()

    # 需要验证的字段列表
    required_fields = ['interface_name', 'ip', 'subnet_mask', 'gateway', 'box_id', 'box_type', 'server_ip']

    # 检查所有需要的字段是否都存在
    valid, message = validate_fields(data, required_fields)
    if not valid:
        return jsonify({'error': message}), 400

    # 在此处添加你对字段值的校验逻辑...

    # 如果所有字段都符合要求，则处理请求并返回结果
    # TODO: 处理请求并返回结果
    return jsonify({'message': '成功'}), 200


if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000, debug=True)

该函数可方便地对字段的存在性统一校验，如果某个字段不存在，立马返回，并在返回信息中提示缺少的字段名。
