微服务(二) php laravel 用户客户端

本节主要讲解通过laravel 作为客户端调用go kratos 服务端，实现用户注册登录

环境

docker desk
laradock
laravel

环境准备

1. 通过laradock php-fpm 安装 grpc protobuf
2. workspace 安装protoc安装 protoc 与 grpc_php_plugin 可执行文件(这个plugin创建整很久)
3. 为方便把grpc_php_plugin放到GRPC文件目录
4. 在worksapce使用protoc 与 grpc_php_plugin 生成客户端代码

protoc --proto_path=./ --php_out=./php-class="lazy" data-src/ --grpc_out=./php-class="lazy" data-src/ --plugin=protoc-gen-grpc=./grpc_php_plugin  ./api/user/v1/user.proto

生成客户端代码

实现

1. 添加客户端调用服务层代码
   
2. 添加grpc 调用组件及GRPC服务的自动加载

composer require grpc/grpccomposer require google/protobuf

grpc 服务文件自动加载

"autoload": {        "psr-4": {            "App\\": "app/",            "Database\\Factories\\": "database/factories/",            "Database\\Seeders\\": "database/seeders/",            "GPBMetadata\\":"GRPC/php-class="lazy" data-src/GPBMetadata/",            "":"GRPC/php-class="lazy" data-src/"        }    },

3. 增加jwt 中间件

composer require firebase/php-jwt

添加中间件app/Http/Middleware/ApiJwt.php

namespace App\Http\Middleware;use App\Service\Jwt;use Closure;use Illuminate\Http\Request;class ApiJwt{        public function handle(Request $request, Closure $next)    {        //将token放入header中传输        $token = $request->header('Authorization');        if (!$token) {            return response()->json(['code' => 500, 'msg' => 'token不存在', 'data' => []]);        }        $result = Jwt::decodeToken($token);        if ($result) {            //将加密id解密传入下一步            $request->attributes->add(['user_id' => $result->user_id, 'nickname' => $result->nickname]);        } else {            return response()->json(['code' => 500, 'msg' => 'token过期', 'data' => []]);        }        return $next($request);    }}

添加jwt 服务app/Service/Jwt.php

namespace App\Service;use Firebase\JWT\JWT as JwtService;use Firebase\JWT\Key;class Jwt{    protected static $key = 'laravel-tiway';    //加密    public static function createToken($userId, $nickname)    {        $payload = array(            "iss" => "http://example.org",            "aud" => "http://example.com",            'exp' => time() + (24 * 3600),            'user_id' => $userId,            'nickname' => $nickname,        );        $jwt = JwtService::encode($payload, self::$key, 'HS256');        return $jwt;    }    //解密    public static function decodeToken($jwt)    {        $decoded = JwtService::decode($jwt, new Key(self::$key, 'HS256'));        if ($decoded) {            return $decoded;        } else {            return false;        }    }}

4. 实现登录注册 app/Http/Controllers/UserController.php

namespace App\Http\Controllers;use App\Service\GrpcUser;use App\Service\Jwt;use Illuminate\Http\Request;class UserController extends Controller{        public function register(Request $request)    {        $input = $request->only('nickname', 'mobile', 'password');        //用户手机号码是否已注册        $user = GrpcUser::getUserByMobile($input['mobile']);        if (isset($user['id'])) {            throw new \Exception('手机号码已被注册');        }        //创建用户        $user = GrpcUser::CreateUser($input['nickname'], $input['mobile'], $input['password']);        if (!isset($user['id'])) {            throw new \Exception('创建失败');        }        return response()->json([            'success' => true,            'data' => $user        ], 200);    }        public function login(Request $request)    {        $input = $request->only('mobile', 'password');        //是否已经存在相同手机号码        $isLogin = GrpcUser::checkoutUserPassword($input['mobile'], $input['password']);        if (!$isLogin) {            throw new \Exception('账号或密码错误');        }        //获取用户信息        $user = GrpcUser::getUserByMobile($input['mobile']);        //jwt        if (isset($user['id'])) {            $token = Jwt::createToken($user['id'], $user['nickname']);        }        return response()->json([            'success' => true,            'token' => $token,        ]);    }        public function getUser(Request $request)    {        $userId = $request->attributes->get('user_id');        $user = GrpcUser::getUserById($userId);        return response()->json(['user' => $user]);    }}

代码参考：laravel-tiway

总结

1. 后期有时间把用户信息全部添加一个redis 缓存
2. 简化controller，添加仓库层实现数据
3. 如果你也是用docker desk,为求方便，联系我，我将提供workspace 和php-fpm 的镜像压缩包
