## 🚀 安装

### 直接使用

```bash
git clone https://github.com/your-repo/WkProtoPHP.git
cd WkProtoPHP
```

### 通过Composer（推荐）

```bash
composer require dongasai/wk-proto-php
```

## 🎯 快速开始

### 基本使用

```php
<?php
require_once 'vendor/autoload.php';

use Dongasai\WkProtoPhp\Protocol;
use Dongasai\WkProtoPhp\ConnectPacket;
use Dongasai\WkProtoPhp\DeviceFlag;

// 创建协议解析器
$protocol = new Protocol();

// 创建CONNECT连接包
$connectPacket = new ConnectPacket();
$connectPacket->setVersion(5);
$connectPacket->setUid('user_123456');
$connectPacket->setToken('your_token_here');
$connectPacket->setDeviceId('device_001');
$connectPacket->setDeviceFlag(DeviceFlag::APP);
$connectPacket->setClientTimestamp(time() * 1000);
$connectPacket->setClientKey('your_client_key');

// 编码数据包
$encodedData = $protocol->encodeFrame($connectPacket);

// 解码数据包
[$decodedPacket, $length, $error] = $protocol->decodeFrame($encodedData);

if ($error) {
    echo "解码失败: " . $error->getMessage();
} else {
    echo "解码成功: " . $decodedPacket;
}
```

### 发送消息

```php
<?php
use Dongasai\WkProtoPhp\SendPacket;
use Dongasai\WkProtoPhp\Setting;
use Dongasai\WkProtoPhp\ChannelType;

// 创建发送包
$sendPacket = new SendPacket();

// 设置消息选项
$setting = new Setting();
$setting->set(Setting::RECEIPT_ENABLED); // 启用回执
$sendPacket->setSetting($setting);

// 设置消息内容
$sendPacket->setMsgKey('unique_msg_key_' . time());
$sendPacket->setClientSeq(1);
$sendPacket->setClientMsgNo('msg_' . uniqid());
$sendPacket->setChannelId('user_002');
$sendPacket->setChannelType(ChannelType::PERSON);
$sendPacket->setPayload('你好，这是一条测试消息！');

// 编码并发送
$encodedMessage = $protocol->encodeFrame($sendPacket);
```

### JSON序列化

所有协议包都支持JSON序列化和反序列化，便于数据存储和传输：

```php
<?php
use Dongasai\WkProtoPhp\RecvPacket;
use Dongasai\WkProtoPhp\Setting;

// 创建RecvPacket
$recvPacket = new RecvPacket();
$recvPacket->setSetting(new Setting(1));
$recvPacket->setMsgKey('test_msg_key');
$recvPacket->setFromUid('user_123456');
$recvPacket->setChannelId('channel_001');
$recvPacket->setChannelType(1);
$recvPacket->setPayload('Hello, World!');
$recvPacket->setMessageId(123456789);
$recvPacket->setMessageSeq(987654321);
$recvPacket->setTimestamp(1640995200);

// 转换为JSON
$json = $recvPacket->toJson();
echo $json;
// 输出:
// {
//     "setting": 1,
//     "msgKey": "test_msg_key",
//     "expire": 0,
//     "messageId": 123456789,
//     "messageSeq": 987654321,
//     "clientMsgNo": "",
//     "streamNo": "",
//     "streamId": 0,
//     "streamFlag": 0,
//     "timestamp": 1640995200,
//     "channelId": "channel_001",
//     "channelType": 1,
//     "topic": "",
//     "fromUid": "user_123456",
//     "payload": "Hello, World!",
//     "clientSeq": 0
// }

// 从JSON恢复对象
$restoredPacket = RecvPacket::fromJson($json);
echo "FromUID: " . $restoredPacket->getFromUid() . "\n";
echo "Payload: " . $restoredPacket->getPayload() . "\n";

// 转换为数组
$array = $recvPacket->toArray();
echo "MessageID: " . $array['messageId'] . "\n";

// 从数组创建对象
$fromArray = RecvPacket::fromArray($array);
echo "ChannelID: " . $fromArray->getChannelId() . "\n";
```

#### 批量JSON处理

```php
// 批量处理多个包
$packets = [];
for ($i = 1; $i <= 3; $i++) {
    $packet = new RecvPacket();
    $packet->setSetting(new Setting($i));
    $packet->setMsgKey("batch_msg_$i");
    $packet->setFromUid("user_$i");
    $packet->setChannelId("channel_$i");
    $packet->setChannelType(1);
    $packet->setPayload("Batch message $i");
    $packet->setMessageId($i * 1000);
    $packet->setTimestamp(1640995200 + $i);
    $packets[] = $packet;
}

// 批量转换为JSON数组
$jsonArray = array_map(function($packet) {
    return json_decode($packet->toJson(), true);
}, $packets);

echo json_encode($jsonArray, JSON_UNESCAPED_UNICODE | JSON_PRETTY_PRINT);

// 批量从JSON恢复
$restoredPackets = array_map(function($jsonData) {
    return RecvPacket::fromJson(json_encode($jsonData));
}, $jsonArray);

echo "恢复的包数量: " . count($restoredPackets) . "\n";
```

#### 数据持久化

```php
// 保存包到文件
function savePacketToFile(Packet $packet, string $filename): void {
    $json = $packet->toJson();
    file_put_contents($filename, $json);
}

// 从文件加载包
function loadPacketFromFile(string $filename): Packet {
    $json = file_get_contents($filename);
    return RecvPacket::fromJson($json);
}

// 使用示例
$packet = new RecvPacket();
$packet->setSetting(new Setting(1));
$packet->setFromUid('user_001');
$packet->setChannelId('channel_001');
$packet->setPayload('Persistent message');

// 保存到文件
savePacketToFile($packet, 'message.json');

// 从文件加载
$loadedPacket = loadPacketFromFile('message.json');
echo "加载的消息: " . $loadedPacket->getPayload() . "\n";
```

## 📚 协议包详解

### CONNECT包

客户端连接时使用的包，包含用户认证信息：

```php
$connectPacket = new ConnectPacket();
$connectPacket->setVersion(5);                    // 协议版本
$connectPacket->setUid('user_001');               // 用户ID
$connectPacket->setToken('auth_token');           // 认证令牌
$connectPacket->setDeviceId('device_001');        // 设备ID
$connectPacket->setDeviceFlag(DeviceFlag::APP);   // 设备类型
$connectPacket->setClientTimestamp(time() * 1000); // 客户端时间戳
$connectPacket->setClientKey('encryption_key');   // 加密密钥
```

### SEND包

发送消息时使用的包：

```php
$sendPacket = new SendPacket();
$sendPacket->setClientSeq(1);                     // 客户端序列号
$sendPacket->setClientMsgNo('msg_001');           // 消息唯一ID
$sendPacket->setChannelId('channel_001');         // 频道ID
$sendPacket->setChannelType(ChannelType::PERSON); // 频道类型
$sendPacket->setPayload('消息内容');              // 消息内容
```

### Setting配置

消息设置标志位，用于控制消息行为：

```php
$setting = new Setting();
$setting->set(Setting::RECEIPT_ENABLED);  // 启用回执
$setting->set(Setting::TOPIC);           // 包含话题
$setting->set(Setting::NO_ENCRYPT);      // 不加密
$setting->set(Setting::STREAM);          // 流消息
```

### SUB包
订阅管理包，用于订阅或取消订阅频道：
```php
$subPacket = new SubPacket();
$subPacket->setSetting(new Setting(1));         // 消息设置
$subPacket->setSubNo('sub_001');               // 订阅编号
$subPacket->setChannelId('channel_001');        // 频道ID
$subPacket->setChannelType(ChannelType::GROUP); // 频道类型
$subPacket->setAction(Action::Subscribe);       // 订阅动作
$subPacket->setParam('subscribe_param');        // 订阅参数
```

### SUBACK包
订阅确认包，服务端响应订阅请求：
```php
$subackPacket = new SubackPacket();
$subackPacket->setSubNo('sub_001');               // 订阅编号
$subackPacket->setChannelId('channel_001');        // 频道ID
$subackPacket->setChannelType(ChannelType::GROUP); // 频道类型
$subackPacket->setAction(Action::Subscribe);       // 订阅动作
$subackPacket->setReasonCode(ReasonCode::Success); // 响应码
```

### EVENT包
事件处理包，用于系统事件通知：
```php
$eventPacket = new EventPacket();
$eventPacket->setId('event_001');          // 事件ID
$eventPacket->setType('user_online');      // 事件类型
$eventPacket->setTimestamp(time());        // 事件时间戳
$eventPacket->setData(json_encode([        // 事件数据
    'user_id' => 'user_001',
    'status' => 'online'
]));
```

## 🔧 常量定义

} catch (Exception $e) {
    echo "错误: " . $e->getMessage() . "\n";
}
```

## 🚀 性能优化

### 批量处理

```php
// 批量编码多个包
$packets = [$packet1, $packet2, $packet3];
$batchData = '';
foreach ($packets as $packet) {
    $batchData .= $protocol->encodeFrame($packet);
}
// 一次性发送
fwrite($socket, $batchData);
```

### 连接池

```php
class ConnectionPool {
    private $connections = [];
    
    public function getConnection($key) {
        if (!isset($this->connections[$key])) {
            $this->connections[$key] = new WuKongIMClient();
            $this->connections[$key]->connect($host, $port, $uid, $token);
        }
        return $this->connections[$key];
    }
}
```

## 🛡️ 错误处理

```php
try {
    [$packet, $length, $error] = $protocol->decodeFrame($data);
    if ($error) {
        throw new Exception("解码失败: " . $error->getMessage());
    }
    
    // 处理解码后的包
    $this->handlePacket($packet);
    
} catch (Exception $e) {
    error_log("协议处理错误: " . $e->getMessage());
    // 错误恢复逻辑
}
```

[固定头部(2字节)][可变长度编码][可变头部][Payload]
```

详细协议规范请参考 [protocol.md](protocol.md)。

## 开发

### 运行测试

```bash
# 运行所有测试
php tests/run_all_tests.php

# 运行特定包测试
php tests/ConnectPacketTest.php
php tests/SendPacketTest.php

# 使用Composer（如果已配置）
composer test
```

### 代码规范

```bash
# 检查代码规范
composer cs-check

# 自动修复代码规范
composer cs-fix
```

### 调试技巧

#### 启用详细日志

```php
$protocol = new Protocol();
$protocol->setDebugMode(true); // 启用调试模式

// 编码时显示详细信息
$encodedData = $protocol->encodeFrame($packet);
echo "编码数据长度: " . strlen($encodedData) . " 字节\n";
echo "编码数据 (hex): " . bin2hex($encodedData) . "\n";

// 解码时显示解析过程
[$packet, $length, $error] = $protocol->decodeFrame($data);
if ($error) {
    echo "解码错误: " . $error->getMessage() . "\n";
    echo "错误代码: " . $error->getCode() . "\n";
}
```

#### 数据包验证

```php
// 验证数据包完整性
public function validatePacket(FrameInterface $packet): bool {
    try {
        // 尝试编码解码循环
        $encoded = $this->protocol->encodeFrame($packet);
        [$decoded, $length, $error] = $this->protocol->decodeFrame($encoded);
        
        if ($error) {
            echo "验证失败: " . $error->getMessage() . "\n";
            return false;
        }
        
        return $packet->getFrameType() === $decoded->getFrameType();
        
    } catch (Exception $e) {
        echo "验证异常: " . $e->getMessage() . "\n";
        return false;
    }
}
```

### 性能分析

```php
// 性能测试示例
$startTime = microtime(true);

// 批量编码测试
$packets = [];
for ($i = 0; $i < 1000; $i++) {
    $packet = new SendPacket();
    $packet->setClientSeq($i);
    $packet->setClientMsgNo('msg_' . $i);
    $packet->setChannelId('user_' . ($i % 10));
    $packet->setChannelType(ChannelType::PERSON);
    $packet->setPayload('测试消息 ' . $i);
    $packets[] = $packet;
}

$encodedData = '';
foreach ($packets as $packet) {
    $encodedData .= $protocol->encodeFrame($packet);
}

$endTime = microtime(true);
echo "编码1000个包耗时: " . round(($endTime - $startTime) * 1000, 2) . " ms\n";
echo "总数据大小: " . strlen($encodedData) . " 字节\n";
echo "平均每个包: " . round(strlen($encodedData) / 1000, 2) . " 字节\n";
```

## 🚨 故障排除

### 常见问题

#### 1. 编码/解码失败

**问题**: `解码失败: Invalid frame type` 或 `编码失败: Data too large`

**解决方案**:
```php
// 检查数据包类型
if ($packet->getFrameType() === FrameType::UNKNOWN) {
    throw new Exception("未知的数据包类型");
}

// 检查数据大小
$maxSize = Protocol::MAX_REMAINING_LENGTH;
if (strlen($data) > $maxSize) {
    throw new Exception("数据超过最大限制: " . $maxSize . " 字节");
}

// 检查协议版本
if ($packet->getVersion() > Protocol::LATEST_VERSION) {
    throw new Exception("不支持的协议版本: " . $packet->getVersion());
}
```

#### 2. 连接认证失败

**问题**: CONNACK返回错误码

**解决方案**:
```php
// 检查CONNACK响应
if ($connack->getReasonCode() !== ReasonCode::SUCCESS) {
    $errorMsg = match($connack->getReasonCode()) {
        ReasonCode::AUTH_FAIL => "认证失败，请检查token",
        ReasonCode::RATE_LIMIT => "请求过于频繁，请稍后重试",
        ReasonCode::SYSTEM_ERROR => "系统错误，请联系管理员",
        default => "未知错误: " . $connack->getReasonCode()
    };
    throw new Exception($errorMsg);
}
```

#### 3. 内存溢出

**问题**: 处理大量消息时内存不足

**解决方案**:
```php
// 分批处理消息
function processMessagesInBatches(array $messages, int $batchSize = 100) {
    foreach (array_chunk($messages, $batchSize) as $batch) {
        foreach ($batch as $message) {
            $packet = $this->createPacketFromMessage($message);
            $encoded = $this->protocol->encodeFrame($packet);
            // 发送数据...
        }
        
        // 手动触发垃圾回收
        if (function_exists('gc_collect_cycles')) {
            gc_collect_cycles();
        }
    }
}

// 限制内存使用
ini_set('memory_limit', '512M');
```

#### 4. 网络连接问题

**问题**: Socket连接超时或断开

**解决方案**:
```php
// 设置socket超时
stream_set_timeout($socket, 30); // 30秒超时

// 检查连接状态
$socketStatus = socket_get_status($socket);
if ($socketStatus['timed_out']) {
    throw new Exception("连接超时");
}

if ($socketStatus['eof']) {
    throw new Exception("连接已断开");
}

// 重连机制
function reconnectWithBackoff($maxRetries = 5) {
    $retryCount = 0;
    $backoffTime = 1; // 初始1秒
    
    while ($retryCount < $maxRetries) {
        try {
            return $this->connect();
        } catch (Exception $e) {
            $retryCount++;
            if ($retryCount >= $maxRetries) {
                throw $e;
            }
            
            sleep($backoffTime);
            $backoffTime *= 2; // 指数退避
        }
    }
}
```

### 调试工具

#### 协议分析器

```php
class ProtocolAnalyzer {
    private Protocol $protocol;
    
    public function analyzeData(string $data): array {
        $analysis = [
            'total_length' => strlen($data),
            'packets' => []
        ];
        
        $offset = 0;
        while ($offset < strlen($data)) {
            $chunk = substr($data, $offset);
            [$packet, $length, $error] = $this->protocol->decodeFrame($chunk);
            
            if ($error) {
                $analysis['error'] = $error->getMessage();
                break;
            }
            
            $analysis['packets'][] = [
                'type' => $packet->getFrameType(),
                'type_name' => FrameType::toString($packet->getFrameType()),
                'length' => $length,
                'offset' => $offset,
                'packet' => $packet
            ];
            
            $offset += $length;
        }
        
        return $analysis;
    }
}
```

#### 数据包监控

```php
class PacketMonitor {
    private array $stats = [
        'encoded' => 0,
        'decoded' => 0,
        'errors' => 0,
        'bytes_sent' => 0,
        'bytes_received' => 0
    ];
    
    public function encodeWithMonitor(FrameInterface $packet): string {
        try {
            $data = $this->protocol->encodeFrame($packet);
            $this->stats['encoded']++;
            $this->stats['bytes_sent'] += strlen($data);
            return $data;
        } catch (Exception $e) {
            $this->stats['errors']++;
            throw $e;
        }
    }
    
    public function decodeWithMonitor(string $data): array {
        try {
            [$packet, $length, $error] = $this->protocol->decodeFrame($data);
            if ($error) {
                throw $error;
            }
            
            $this->stats['decoded']++;
            $this->stats['bytes_received'] += $length;
            return [$packet, $length, null];
        } catch (Exception $e) {
            $this->stats['errors']++;
            throw $e;
        }
    }
    
    public function getStats(): array {
        return $this->stats;
    }
}
```
