逸逸肆云

使用已建好的运维开发环境，可用区为华北-北京4，在/root/huaweicloud_fastapi目录下创建main.py文件，基于FastAPI框架，完成虚拟私有云VPC管理服务的封装，端口为7045。
提示说明：华为云主机支持安装所需Python库。提交前答案前，需安装所开发程序所依赖的Python库。
（1）封装创建接口，路径为/cloud_vpc/create_vpc，参数格式为{"name": "","cidr": ""},name为VPC名称，cidr为虚拟私有云下可用子网的范围；方法为POST，返回数据类型为JSON类型。
（2）封装单个VPC查询接口，路径为/cloud_vpc/vpc/{vpc_name}，路径中{vpc_name}为待查询VPC；方法为GET，返回数据类型为JSON类型。
（3）封装服务查询接口，要求可以查询到所有VPC，路径为/cloud_vpc/vpc；方法为GET，返回的数据类型JSON类型的列表类型。
（4）封装更新VPN名称接口，路径为/cloud_vpc/update_vpc，参数格式为{"new_name": "","old_name": ""}，new_name为VPC新名称，old_name为待删除的VPN名称；方法为PUT，返回JSON类型的更新后数据。
（5）封装删除接口，接口名为/cloud_vpc/delete_vpc，参数格式为{"vpc_name": ""}，vpc_name为VPC新名称；方法为DELETE，返回JSON类型的删除后的数据。
功能编写完成后，手工启动Restful服务，再提交检测。
