+# Transfer模块API参数优化
+
+> 任务时间: 2025-06-18 20:27  
+> 任务类型: API优化  
+> 状态: ✅ 已完成
+
+## 任务概述
+
+针对用户反馈的"createTransferOut，createTransferIn 使用数组参数，是难以理解的"问题，对Transfer模块的核心API进行了全面优化，使用明确的参数列表替代数组参数，提高代码的可读性和类型安全性。
+
+## 优化内容
+
+### 1. TransferService 服务层优化
+
+**优化前：**
+```php
+public static function createTransferOut(array $data): TransferOrderDto|string
+public static function createTransferIn(array $data): TransferOrderDto|string
+```
+
+**优化后：**
+```php
+// 转出订单 - 明确参数
+public static function createTransferOut(
+    int $transferAppId,
+    int $userId,
+    string $amount,
+    string $password,
+    ?string $googleCode = null,
+    ?string $outUserId = null,
+    ?string $remark = null,
+    array $callbackData = []
+): TransferOrderDto|string
+
+// 转入订单 - 明确参数
+public static function createTransferIn(
+    int $transferAppId,
+    int $userId,
+    string $businessId,
+    string $amount,
+    ?string $outUserId = null,
+    ?string $remark = null,
+    array $callbackData = []
+): TransferOrderDto|string
+```
+
+### 2. TransferLogic 逻辑层优化
+
+**新增方法结构：**
+- `createTransferOut()` - 对外接口，使用明确参数
+- `createTransferOutFromArray()` - 内部实现，保持向后兼容
+- `createTransferIn()` - 对外接口，使用明确参数  
+- `createTransferInFromArray()` - 内部实现，保持向后兼容
+
+### 3. OpenAPI Handler 更新
+
+**优化前：**
+```php
+$result = TransferService::createTransferOut($validatedData);
+```
+
+**优化后：**
+```php
+$result = TransferService::createTransferOut(
+    transferAppId: $validatedData['transfer_app_id'],
+    userId: $validatedData['user_id'],
+    amount: $validatedData['amount'],
+    password: $validatedData['password'],
+    googleCode: $validatedData['google_code'] ?? null,
+    outUserId: $validatedData['out_user_id'] ?? null,
+    remark: $validatedData['remark'] ?? null,
+    callbackData: $validatedData['callback_data'] ?? []
+);
+```
+
+### 4. 新增便捷方法
+
+**快速创建方法：**
+```php
+// 快速转出 - 只需必要参数
+public static function quickCreateTransferOut(
+    int $transferAppId,
+    int $userId,
+    string $amount,
+    string $password
+): TransferOrderDto|string
+
+// 快速转入 - 只需必要参数
+public static function quickCreateTransferIn(
+    int $transferAppId,
+    int $userId,
+    string $businessId,
+    string $amount
+): TransferOrderDto|string
+```
+
+**向后兼容方法：**
+```php
+// 标记为废弃，但保持兼容
+public static function createTransferOutFromArray(array $data): TransferOrderDto|string
+public static function createTransferInFromArray(array $data): TransferOrderDto|string
+```
+
+### 5. 测试文件更新
+
+- 更新所有测试方法使用新的 `FromArray` 方法
+- 新增测试用例展示新的参数化API
+- 测试可选参数的默认值处理
+
+## 优化优势
+
+### 1. 类型安全

+
+## 使用示例
+
+### 基础用法
+
+```php
+// 转出订单
+$result = TransferService::createTransferOut(
+    transferAppId: 1,
+    userId: 12345,
+    amount: '100.50',
+    password: 'user_password'
+);
+
+// 转入订单
+$result = TransferService::createTransferIn(
+    transferAppId: 1,
+    userId: 12345,
+    businessId: 'BIZ_20250618_001',
+    amount: '100.50'
+);
+```
+
+### 完整参数用法
+
+```php
+$result = TransferService::createTransferOut(
+    transferAppId: 1,
+    userId: 12345,
+    amount: '100.50',
+    password: 'user_password',
+    googleCode: '123456',
+    outUserId: 'external_user_123',
+    remark: '游戏充值',
+    callbackData: ['game_id' => 'abc']
+);
+```
+
+### 错误处理
+
+```php
+$result = TransferService::createTransferOut(/* 参数 */);
+
+if (is_string($result)) {
+    // 处理错误
+    $errorMessage = $result;
+} else {
+    // 处理成功
+    $order = $result; // TransferOrderDto 对象
+}
+```
+
+## 迁移指南

+```php
+TransferService::createTransferOut(
+    transferAppId: $appId,
+    userId: $userId,
+    amount: $amount,
+    password: $password
+);
+```
+
+### 2. 现有项目
+可以继续使用数组参数（标记为废弃）：
+```php
+TransferService::createTransferOutFromArray($data);
+```
+
+### 3. 渐进迁移
+逐步将数组参数调用替换为新的参数化调用。
+
+## 文档更新
+

+ADD COLUMN fee_out_max DECIMAL(15,4) DEFAULT 0.0000 COMMENT '转出最高手续费',
+ADD COLUMN fee_account_uid INT DEFAULT 0 COMMENT '手续费收取账户UID';
+```
+
+### 订单表新增字段 (transfer_orders)
+
+```sql
+ALTER TABLE kku_transfer_orders
+ADD COLUMN fee_rate DECIMAL(5,4) DEFAULT 0.0000 COMMENT '使用的手续费率',
+ADD COLUMN fee_amount DECIMAL(15,4) DEFAULT 0.0000 COMMENT '手续费金额',
+ADD COLUMN actual_amount DECIMAL(15,4) DEFAULT 0.0000 COMMENT '实际到账金额';
+```
+
+## 核心代码实现
+
+### 1. 模型层增强

+- `getFeeAccount()` - 获取手续费账户信息
+
+**TransferOrder 模型新增方法:**
+- `hasFee()` - 判断是否有手续费
+- `setFeeInfo()` - 设置手续费信息
+- `calculateFeeFromApp()` - 从应用配置计算手续费
+
+### 2. 服务层扩展
+
+**TransferService 新增方法:**
+- `calculateInFee()` - 计算转入手续费
+- `calculateOutFee()` - 计算转出手续费
+- `getFeeConfig()` - 获取手续费配置
+- `getFeeStatistics()` - 获取手续费统计
+- `getAppFeeIncome()` - 获取应用手续费收入

+- 支持手续费账户的资金分配
+
+### 4. DTO层增强
+
+**TransferOrderDto 新增字段:**
+- `fee_rate` - 手续费率
+- `fee_amount` - 手续费金额
+- `actual_amount` - 实际到账金额
+- 新增手续费相关的格式化方法
+
+## API使用示例
+
+### 手续费计算
+
+```php
+// 计算转出手续费
+$feeInfo = TransferService::calculateOutFee(
+    transferAppId: 1,
+    amount: '100.00'
+);
+// 返回: ['fee_rate' => 0.01, 'fee_amount' => '1.0000', 'actual_amount' => '99.0000']
+
+// 计算转入手续费
+$feeInfo = TransferService::calculateInFee(
+    transferAppId: 1,
+    amount: '100.00'
+);
+```
+
+### 创建订单（自动计算手续费）
+
+```php
+// 转出订单 - 自动扣除手续费
+$result = TransferService::createTransferOut(
+    transferAppId: 1,
+    userId: 12345,
+    amount: '100.00',
+    password: 'password'
+);
+
+// 转入订单 - 自动计算实际到账金额
+$result = TransferService::createTransferIn(
+    transferAppId: 1,
+    userId: 12345,
+    businessId: 'BIZ_001',
+    amount: '100.00'
+);
+```
+
+### 手续费统计
+
+```php
+// 获取手续费配置
+$config = TransferService::getFeeConfig(transferAppId: 1);
+
+// 获取手续费统计
+$stats = TransferService::getFeeStatistics(
+    appId: 1,
+    startDate: '2025-06-01',
+    endDate: '2025-06-30'
+);
+
+// 获取应用收入统计
+$income = TransferService::getAppFeeIncome(appId: 1, days: 30);
+```
+
+## 手续费计算规则
+
+### 计算公式
+1. **按比例计算**: `手续费 = 金额 × 手续费率`
+2. **最低限制**: `if (手续费 < 最低手续费) 手续费 = 最低手续费`
+3. **最高限制**: `if (最高手续费 > 0 && 手续费 > 最高手续费) 手续费 = 最高手续费`
+4. **实际到账**: `实际到账金额 = 原金额 - 手续费`
+
+### 示例计算
+应用配置: 费率1%, 最低0.5, 最高10
+
+| 金额 | 按比例 | 应用限制 | 实际到账 |
+|------|--------|----------|----------|
+| 10.00 | 0.10 | 0.50 | 9.50 |
+| 100.00 | 1.00 | 1.00 | 99.00 |
+| 1500.00 | 15.00 | 10.00 | 1490.00 |
+
+## 资金流向
+
+### 转出订单
+```
+用户账户 → 目标账户 (实际到账金额，扣除手续费后)
+用户账户 → 手续费账户 (手续费，默认UID 1)
+```
+
+### 转入订单
+```
+来源账户 → 用户账户 (实际到账金额，扣除手续费后)
+来源账户 → 手续费账户 (手续费，默认UID 1)
+```
+
+### 默认手续费账户机制
+- **默认账户**: UID 1
+- **使用规则**: 当应用未配置 `fee_account_uid` 或配置为0时，自动使用UID 1
+- **优先级**: 应用配置 > 默认UID 1
+- **确保收取**: 无论是否配置，手续费都会被正确收取

+# Transfer模块API使用指南
+
+## 概述
+
+Transfer模块提供了明确的参数接口，替代了原来难以理解的数组参数方式。新的API更加类型安全，易于理解和维护。
+
+## 创建转出订单
+
+### 完整参数版本
+
+```php
+use App\Module\Transfer\Services\TransferService;
+
+// 创建转出订单 - 完整参数
+$result = TransferService::createTransferOut(
+    transferAppId: 1,                    // 划转应用ID
+    userId: 12345,                       // 用户ID
+    amount: '100.50',                    // 转出金额
+    password: 'user_password',           // 安全密码
+    googleCode: '123456',                // 谷歌验证码（可选）
+    outUserId: 'external_user_123',      // 外部用户ID（可选）
+    remark: '游戏充值',                   // 备注（可选）
+    callbackData: ['game_id' => 'abc']   // 回调数据（可选）
+);
+
+if (is_string($result)) {
+    // 处理错误
+    echo "创建失败: " . $result;
+} else {
+    // 成功，$result 是 TransferOrderDto 对象
+    echo "订单创建成功，ID: " . $result->id;
+}
+```
+
+### 简化版本
+
+```php
+// 快速创建转出订单 - 只需必要参数
+$result = TransferService::quickCreateTransferOut(
+    transferAppId: 1,
+    userId: 12345,
+    amount: '100.50',
+    password: 'user_password'
+);
+```
+
+## 创建转入订单
+
+### 完整参数版本
+
+```php
+// 创建转入订单 - 完整参数
+$result = TransferService::createTransferIn(
+    transferAppId: 1,                    // 划转应用ID
+    userId: 12345,                       // 用户ID
+    businessId: 'BIZ_20250618_001',      // 业务订单ID
+    amount: '100.50',                    // 转入金额
+    outUserId: 'external_user_123',      // 外部用户ID（可选）
+    remark: '游戏提现',                   // 备注（可选）
+    callbackData: ['game_id' => 'abc']   // 回调数据（可选）
+);
+```
+
+### 简化版本
+
+```php
+// 快速创建转入订单 - 只需必要参数
+$result = TransferService::quickCreateTransferIn(
+    transferAppId: 1,
+    userId: 12345,
+    businessId: 'BIZ_20250618_001',
+    amount: '100.50'
+);
+```
+
+## 向后兼容
+
+如果您的代码仍在使用数组参数，可以使用向后兼容方法：
+
+```php
+// 向后兼容 - 转出订单
+$data = [
+    'transfer_app_id' => 1,
+    'user_id' => 12345,
+    'amount' => '100.50',
+    'password' => 'user_password',
+    'google_code' => '123456',
+    'out_user_id' => 'external_user_123',
+    'remark' => '游戏充值',
+    'callback_data' => ['game_id' => 'abc']
+];
+
+$result = TransferService::createTransferOutFromArray($data);
+
+// 向后兼容 - 转入订单
+$data = [
+    'transfer_app_id' => 1,
+    'user_id' => 12345,
+    'business_id' => 'BIZ_20250618_001',
+    'amount' => '100.50',
+    'out_user_id' => 'external_user_123',
+    'remark' => '游戏提现',
+    'callback_data' => ['game_id' => 'abc']
+];
+
+$result = TransferService::createTransferInFromArray($data);
+```
+
+## 参数说明
+
+### 转出订单参数
+
+| 参数名 | 类型 | 必填 | 说明 |
+|--------|------|------|------|
+| transferAppId | int | 是 | 划转应用ID |
+| userId | int | 是 | 用户ID |
+| amount | string | 是 | 转出金额（字符串格式，支持小数） |
+| password | string | 是 | 用户安全密码 |
+| googleCode | string\|null | 否 | 谷歌验证码（6位数字） |
+| outUserId | string\|null | 否 | 外部用户ID |
+| remark | string\|null | 否 | 备注信息 |
+| callbackData | array | 否 | 回调数据（键值对数组） |
+
+### 转入订单参数
+
+| 参数名 | 类型 | 必填 | 说明 |
+|--------|------|------|------|
+| transferAppId | int | 是 | 划转应用ID |
+| userId | int | 是 | 用户ID |
+| businessId | string | 是 | 业务订单ID（外部系统的订单标识） |

+| outUserId | string\|null | 否 | 外部用户ID |
+| remark | string\|null | 否 | 备注信息 |
+| callbackData | array | 否 | 回调数据（键值对数组） |
+
+## 返回值处理
+
+所有创建方法都返回 `TransferOrderDto|string`：
+
+- 成功时返回 `TransferOrderDto` 对象
+- 失败时返回错误信息字符串
+
+```php
+$result = TransferService::createTransferOut(/* 参数 */);
+
+if (is_string($result)) {
+    // 处理错误
+    $errorMessage = $result;
+    // 记录日志、返回错误响应等
+} else {
+    // 处理成功
+    $order = $result; // TransferOrderDto 对象
+    $orderId = $order->id;
+    $status = $order->status;
+    $amount = $order->amount;
+    // 其他业务逻辑
+}
+```
+
+## 最佳实践
+
+1. **使用命名参数**：PHP 8.0+ 支持命名参数，提高代码可读性
+2. **类型检查**：利用返回值类型检查处理成功和失败情况
+3. **错误处理**：始终检查返回值类型，妥善处理错误情况
+4. **参数验证**：在调用API前进行基础参数验证
+5. **日志记录**：记录重要的操作和错误信息
+
+## 迁移指南
+
+### 从数组参数迁移
+
+**旧代码：**
+```php
+$data = [
+    'transfer_app_id' => 1,
+    'user_id' => 12345,
+    'amount' => '100.50',
+    'password' => 'password'
+];
+$result = TransferService::createTransferOut($data);
+```
+
+**新代码：**
+```php
+$result = TransferService::createTransferOut(
+    transferAppId: 1,
+    userId: 12345,
+    amount: '100.50',
+    password: 'password'
+);
+```
+
+### 优势
+
+1. **类型安全**：编译时检查参数类型
+2. **IDE支持**：更好的代码补全和提示
+3. **可读性**：参数含义一目了然
+4. **维护性**：减少参数错误和遗漏
+5. **文档化**：参数名称即文档
+
+## 注意事项
+
+1. 金额参数使用字符串类型，避免浮点数精度问题
+2. 可选参数使用 null 作为默认值
+3. 回调数据必须是关联数组格式
+4. 业务订单ID必须在同一应用内唯一
+5. 密码和验证码等敏感信息需要妥善处理

+# Transfer模块手续费功能使用指南
+
+## 概述
+
+Transfer模块现已支持转入/转出手续费功能，可以为每个划转应用配置不同的手续费率、最低手续费和最高手续费。
+
+## 数据库字段说明
+
+### 应用配置表 (transfer_apps)
+
+| 字段名 | 类型 | 说明 |
+|--------|------|------|
+| fee_in_rate | DECIMAL(5,4) | 转入手续费率(0.0000-1.0000) |
+| fee_out_rate | DECIMAL(5,4) | 转出手续费率(0.0000-1.0000) |
+| fee_in_min | DECIMAL(15,4) | 转入最低手续费 |
+| fee_in_max | DECIMAL(15,4) | 转入最高手续费(0为不限制) |
+| fee_out_min | DECIMAL(15,4) | 转出最低手续费 |
+| fee_out_max | DECIMAL(15,4) | 转出最高手续费(0为不限制) |
+| fee_account_uid | INT | 手续费收取账户UID（默认为1） |
+
+### 订单表 (transfer_orders)
+
+| 字段名 | 类型 | 说明 |
+|--------|------|------|
+| fee_rate | DECIMAL(5,4) | 使用的手续费率 |
+| fee_amount | DECIMAL(15,4) | 手续费金额 |
+| actual_amount | DECIMAL(15,4) | 实际到账金额(扣除手续费后) |
+
+## 手续费计算规则
+
+### 计算公式
+
+1. **按比例计算**: `手续费 = 金额 × 手续费率`
+2. **最低限制**: `if (手续费 < 最低手续费) 手续费 = 最低手续费`
+3. **最高限制**: `if (最高手续费 > 0 && 手续费 > 最高手续费) 手续费 = 最高手续费`
+4. **实际到账**: `实际到账金额 = 原金额 - 手续费`
+
+### 示例
+
+假设应用配置：
+- 转出手续费率: 1% (0.0100)
+- 最低手续费: 0.50
+- 最高手续费: 10.00
+
+不同金额的手续费计算：
+
+| 转出金额 | 按比例计算 | 应用限制后 | 实际到账 |
+|----------|------------|------------|----------|
+| 10.00 | 0.10 | 0.50 (最低) | 9.50 |
+| 100.00 | 1.00 | 1.00 | 99.00 |
+| 1500.00 | 15.00 | 10.00 (最高) | 1490.00 |
+
+## API使用示例
+
+### 1. 计算手续费
+
+```php
+use App\Module\Transfer\Services\TransferService;
+
+// 计算转出手续费
+$feeInfo = TransferService::calculateOutFee(
+    transferAppId: 1,
+    amount: '100.00'
+);
+
+// 返回结果
+[
+    'fee_rate' => 0.0100,        // 手续费率
+    'fee_amount' => '1.0000',    // 手续费金额
+    'actual_amount' => '99.0000' // 实际到账金额
+]
+
+// 计算转入手续费
+$feeInfo = TransferService::calculateInFee(
+    transferAppId: 1,
+    amount: '100.00'
+);
+```
+
+### 2. 创建订单（自动计算手续费）
+
+```php
+// 转出订单 - 手续费会自动计算并从用户账户扣除
+$result = TransferService::createTransferOut(
+    transferAppId: 1,
+    userId: 12345,
+    amount: '100.00',
+    password: 'user_password'
+);
+
+// 转入订单 - 手续费会自动计算，用户收到扣除手续费后的金额
+$result = TransferService::createTransferIn(
+    transferAppId: 1,
+    userId: 12345,
+    businessId: 'BIZ_001',
+    amount: '100.00'
+);
+```
+
+### 3. 获取手续费配置
+
+```php
+$config = TransferService::getFeeConfig(transferAppId: 1);
+
+// 返回结果
+[
+    'in' => [
+        'rate' => 0.0050,     // 转入费率 0.5%
+        'min' => 0.1000,      // 最低 0.1
+        'max' => 5.0000,      // 最高 5.0
+        'enabled' => true     // 是否启用
+    ],
+    'out' => [
+        'rate' => 0.0100,     // 转出费率 1.0%
+        'min' => 0.2000,      // 最低 0.2
+        'max' => 10.0000,     // 最高 10.0
+        'enabled' => true     // 是否启用
+    ],
+    'account_uid' => 999      // 手续费收取账户
+]
+```
+
+### 4. 获取手续费统计
+
+```php
+// 获取所有应用的手续费统计
+$stats = TransferService::getFeeStatistics();
+
+// 获取指定应用和时间范围的统计
+$stats = TransferService::getFeeStatistics(
+    appId: 1,
+    startDate: '2025-06-01',
+    endDate: '2025-06-30'
+);
+
+// 返回结果
+[
+    'total_orders' => 150,      // 总订单数
+    'total_fee' => 125.50,      // 总手续费
+    'avg_fee_rate' => 0.0075,   // 平均费率
+    'in_orders' => 80,          // 转入订单数
+    'in_fee' => 60.25,          // 转入手续费
+    'out_orders' => 70,         // 转出订单数
+    'out_fee' => 65.25,         // 转出手续费
+]
+
+// 获取应用的手续费收入统计
+$income = TransferService::getAppFeeIncome(
+    appId: 1,
+    days: 30
+);
+```
+
+## 资金流向说明
+
+### 转出订单资金流向
+
+1. **用户账户** → **目标账户** (实际到账金额，扣除手续费后)
+2. **用户账户** → **手续费账户** (手续费金额)
+
+```
+用户余额: 1000.00
+转出金额: 100.00
+手续费: 1.00
+实际转出: 99.00
+
+执行后:
+- 用户余额: 899.00 (扣除 100.00)
+- 目标账户: +99.00 (实际到账)
+- 手续费账户: +1.00
+```
+
+### 转入订单资金流向
+
+1. **来源账户** → **用户账户** (实际到账金额，扣除手续费后)
+2. **来源账户** → **手续费账户** (手续费金额)
+
+```
+来源账户余额: 1000.00
+转入金额: 100.00
+手续费: 1.00
+实际到账: 99.00
+
+执行后:
+- 来源账户余额: 900.00 (扣除 100.00)
+- 用户账户: +99.00 (实际到账)
+- 手续费账户: +1.00
+```
+
+### 默认手续费账户
+
+- **默认账户UID**: 1
+- **使用规则**: 如果应用未配置 `fee_account_uid` 或配置为0，系统自动使用账户UID 1收取手续费
+- **配置优先级**: 应用配置的手续费账户 > 默认账户UID 1
+
+## 配置示例
+
+### 1. 数据库配置
+
+```sql
+-- 配置应用手续费
+UPDATE kku_transfer_apps 
+SET 
+    fee_in_rate = 0.0050,    -- 转入手续费 0.5%
+    fee_out_rate = 0.0100,   -- 转出手续费 1.0%
+    fee_in_min = 0.1000,     -- 转入最低手续费 0.1
+    fee_in_max = 10.0000,    -- 转入最高手续费 10
+    fee_out_min = 0.2000,    -- 转出最低手续费 0.2
+    fee_out_max = 20.0000,   -- 转出最高手续费 20
+    fee_account_uid = 1      -- 手续费收取账户
+WHERE keyname = 'game_app';
+```
+
+### 2. 模型使用
+
+```php
+use App\Module\Transfer\Models\TransferApp;
+
+$app = TransferApp::find(1);
+
+// 检查是否启用手续费
+if ($app->isFeeEnabled('out')) {
+    echo "转出手续费已启用";
+}
+
+// 计算手续费
+$feeInfo = $app->calculateOutFee('100.00');
+echo "手续费: {$feeInfo['fee_amount']}";
+echo "实际到账: {$feeInfo['actual_amount']}";
+```
+
+### 3. 订单信息
+
+```php
+use App\Module\Transfer\Models\TransferOrder;
+
+$order = TransferOrder::find(1);
+
+// 检查是否有手续费
+if ($order->hasFee()) {
+    echo "手续费率: {$order->getFeeRatePercentAttribute()}";
+    echo "手续费金额: {$order->getFeeAmountTextAttribute()}";
+    echo "实际到账: {$order->getActualAmountTextAttribute()}";
+}
+```
+
+## 注意事项
+
+1. **手续费率范围**: 0.0000 - 1.0000 (0% - 100%)
+2. **最低手续费**: 不能为负数
+3. **最高手续费**: 0表示不限制，大于0时生效
+4. **手续费账户**: 必须是有效的Fund账户UID
+5. **精度处理**: 所有金额计算使用4位小数精度
+6. **向后兼容**: 现有订单的手续费字段默认为0
+
+## 监控和报警
+
+### 1. 手续费异常监控
+
+```sql
+-- 查找手续费异常高的订单
+SELECT 
+    id, transfer_app_id, amount, fee_rate, fee_amount, created_at
+FROM kku_transfer_orders 
+WHERE fee_rate > 0.1000  -- 手续费率超过10%
+OR fee_amount > amount * 0.1  -- 手续费超过金额的10%
+ORDER BY created_at DESC;
+```
+
+### 2. 手续费收入统计
+
+```sql
+-- 手续费收入日报
+SELECT 
+    DATE(created_at) as date,
+    COUNT(*) as orders,
+    SUM(fee_amount) as total_fee,
+    AVG(fee_rate) as avg_rate
+FROM kku_transfer_orders 
+WHERE status = 100 AND fee_amount > 0
+AND created_at >= DATE_SUB(CURDATE(), INTERVAL 30 DAY)
+GROUP BY DATE(created_at)
+ORDER BY date DESC;
+```
+
+## 最佳实践
+
+1. **合理设置费率**: 根据业务需求设置合理的手续费率
+2. **设置限制**: 使用最低和最高手续费限制保护用户
+3. **监控收入**: 定期监控手续费收入和异常情况
+4. **账户管理**: 确保手续费收取账户有足够的权限和安全性
+5. **用户提示**: 在用户界面明确显示手续费信息
+
+## 故障排除
+
+### 常见问题
+
+1. **手续费计算错误**: 检查应用配置和计算逻辑
+2. **手续费未收取**: 检查fee_account_uid配置
+3. **余额不足**: 确保来源账户有足够余额
+4. **精度问题**: 使用bcmath函数进行精确计算
+
+### 调试方法
+
+```php
+// 调试手续费计算
+$app = TransferApp::find(1);
+$feeInfo = $app->calculateOutFee('100.00');
+var_dump($feeInfo);
+
+// 检查订单手续费信息
+$order = TransferOrder::find(1);
+echo "原金额: {$order->amount}";
+echo "手续费: {$order->fee_amount}";
+echo "实际金额: {$order->actual_amount}";
