用户服务

微服务(python)

目录结构

创建虚拟环境 

mkvirtualenv mxshop_srv

用户表设计 

pip3 install peewee
pip3 install pymysql

from abc import ABC

if __name__ == '__main__':
    settings.DB.create_tables([User])  # 创建表

密码处理 

# https://passlib.readthedocs.io/en/stable/

# 安装
pip install passwlib

# 使用
from passlib.hash import pbkdf2_sha256

hash1 = pbkdf2_sha256.hash("123456")
print(hash1)
print(pbkdf2_sha256.verify("123456", hash1))  # 校验 返回bool

# 存入用户
for i in range(10):
    user = User()
    user.nick_name = f"user{i}"
    user.mobile = f"1308822955{i}"
    user.password = pbkdf2_sha256.hash("admin123")
    user.save()

# 校验用户密码
for user in User.select():
    print(pbkdf2_sha256.verify("admin123", user.password))  # 返回 True

proto接口定义

user_srv/proto/user.proto 

syntax = "proto3";
import "google/protobuf/empty.proto";
option go_package = "../proto";

service User {
    rpc GetUserList(PageInfo) returns (UserListResonse); //用户列表
    rpc GetUserByMobile(MobileRequest) returns (UserInfoResponse); //通过mobile查询用户

    rpc UpdateUser(UpdateUserInfo) returns (google.protobuf.Empty); // 更新用户
    rpc CheckPassWord (PasswordCheckInfo) returns (CheckResponse); //检查密码
}

message PasswordCheckInfo {
    string password = 1;
    string encryptedPassword = 2;
}

message CheckResponse {
    bool success = 1;
}

message PageInfo {
    uint32 pn = 1;
    uint32 pSize = 2;
}

message MobileRequest {
    string mobile = 1;
}

message IdRequest {
    int32 id = 1;
}

message CreateUserInfo {
    string nickName = 1;
    string passWord = 2;
    string mobile = 3;
}

message UpdateUserInfo {
    int32 id = 1;
    string nickName = 2;
    string gender = 3;
    uint64 birthDay = 4;
}


message UserInfoResponse {
    int32 id = 1;
    string passWord = 2;
    string mobile = 3;
    string nickName = 4;
    uint64 birthDay = 5;
    string gender = 6;
    int32 role = 7;
}

message UserListResonse {
    int32 total = 1;
    repeated UserInfoResponse data = 2;
}

安装模块生成文件 

# 安装模块
pip3 install grpcio
pip3 install grpcio-tools

# 生成文件
cd user_srv/proto/
python3 -m grpc_tools.protoc --python_out=. --grpc_python_out=. -I. user.proto

# 修改导入
user_srv/proto/user_pb2_grpc.py 文件中
import user_pb2 as user__pb2 改为
from . import user_pb2 as user__pb2

日志库loguru 

pip install loguru

# 日志文件 切割
logger.add("logs/user_srv_{time}.log", rotation="200 MB")

# 颜色
logger.debug("调试信息")
logger.info("普通信息")
logger.warning("警告信息")
logger.error("错误信息")
logger.critical("严重错误信息")

# 装饰器
@logger.catch
def my_func(x, y, z):
    return 1 / (x + y + z)
my_func(0, 0, 0)

# 上下文比较全
