+# 境外微信支付(Overseas WeChat Pay)支持
+
+本次更新添加了境外微信支付的支持，解决了 [Issue #3618](https://github.com/binarywang/WxJava/issues/3618) 中提到的问题。
+
+## 问题背景
+
+境外微信支付需要使用新的API接口地址和额外的参数：
+- 使用不同的基础URL: `https://apihk.mch.weixin.qq.com` 
+- 需要额外的参数: `trade_type` 和 `merchant_category_code`
+- 使用不同的API端点: `/global/v3/transactions/*`
+
+## 新增功能
+
+### 1. GlobalTradeTypeEnum
+新的枚举类，定义了境外支付的交易类型和对应的API端点：
+- `APP`: `/global/v3/transactions/app`
+- `JSAPI`: `/global/v3/transactions/jsapi`
+- `NATIVE`: `/global/v3/transactions/native`
+- `H5`: `/global/v3/transactions/h5`
+
+### 2. WxPayUnifiedOrderV3GlobalRequest
+扩展的请求类，包含境外支付必需的额外字段：
+- `trade_type`: 交易类型 (JSAPI, APP, NATIVE, H5)
+- `merchant_category_code`: 商户类目代码（境外商户必填）
+
+### 3. 新的服务方法
+- `createOrderV3Global()`: 创建境外支付订单
+- `unifiedOrderV3Global()`: 境外统一下单接口
+
+## 使用示例
+
+### JSAPI支付示例
+```java
+// 创建境外支付请求
+WxPayUnifiedOrderV3GlobalRequest request = new WxPayUnifiedOrderV3GlobalRequest();
+request.setOutTradeNo(RandomUtils.getRandomStr());
+request.setDescription("境外商品购买");
+request.setNotifyUrl("https://your-domain.com/notify");
+
+// 设置金额
+WxPayUnifiedOrderV3GlobalRequest.Amount amount = new WxPayUnifiedOrderV3GlobalRequest.Amount();
+amount.setCurrency(WxPayConstants.CurrencyType.CNY);
+amount.setTotal(100); // 1元，单位为分
+request.setAmount(amount);
+
+// 设置支付者
+WxPayUnifiedOrderV3GlobalRequest.Payer payer = new WxPayUnifiedOrderV3GlobalRequest.Payer();
+payer.setOpenid("用户的openid");
+request.setPayer(payer);
+
+// 设置境外支付必需的参数
+request.setTradeType("JSAPI");
+request.setMerchantCategoryCode("5812"); // 商户类目代码
+
+// 调用境外支付接口
+WxPayUnifiedOrderV3Result.JsapiResult result = payService.createOrderV3Global(
+    GlobalTradeTypeEnum.JSAPI, 
+    request
+);
+```
+
+### APP支付示例
+```java
+WxPayUnifiedOrderV3GlobalRequest request = new WxPayUnifiedOrderV3GlobalRequest();
+// ... 设置基础信息 ...
+
+request.setTradeType("APP");
+request.setMerchantCategoryCode("5812");
+request.setPayer(new WxPayUnifiedOrderV3GlobalRequest.Payer()); // APP支付不需要openid
+
+WxPayUnifiedOrderV3Result.AppResult result = payService.createOrderV3Global(
+    GlobalTradeTypeEnum.APP, 
+    request
+);
+```
+
+### NATIVE支付示例
+```java
+WxPayUnifiedOrderV3GlobalRequest request = new WxPayUnifiedOrderV3GlobalRequest();
+// ... 设置基础信息 ...
+
+request.setTradeType("NATIVE");
+request.setMerchantCategoryCode("5812");
+request.setPayer(new WxPayUnifiedOrderV3GlobalRequest.Payer());
+
+String codeUrl = payService.createOrderV3Global(
+    GlobalTradeTypeEnum.NATIVE, 
+    request
+);
+```
+
+## 配置说明
+
+境外支付使用相同的 `WxPayConfig` 配置，无需特殊设置：
+
+```java
+WxPayConfig config = new WxPayConfig();
+config.setAppId("你的AppId");
+config.setMchId("你的境外商户号");
+config.setMchKey("你的商户密钥");
+config.setNotifyUrl("https://your-domain.com/notify");
+
+// V3相关配置
+config.setPrivateKeyPath("你的私钥文件路径");
+config.setCertSerialNo("你的商户证书序列号");
+config.setApiV3Key("你的APIv3密钥");
+```
+
+**注意**: 境外支付会自动使用 `https://apihk.mch.weixin.qq.com` 作为基础URL，无需手动设置。
+
+## 兼容性
+
+- 完全向后兼容，不影响现有的国内支付功能
+- 使用相同的配置类和结果类
+- 遵循现有的代码风格和架构模式
+
+## 参考文档
+
+- [境外微信支付文档](https://pay.weixin.qq.com/doc/global/v3/zh/4013014223)
+- [原始Issue #3618](https://github.com/binarywang/WxJava/issues/3618)
