- 流程：
- 客户端向自己的服务端申请订单，服务端同步到微信服务端
- 客户端收到订单后，调起微信进行支付
- 等微信返回后，会通知客户端，然后根据结果向自己的服务端请求相关信息
- 同时服务端会接受微信服务端的支付成功失败通知，也可以向微信服务端查询支付情况
- android的sdk已经升级过，从sdk变成了opensdk，下载wechat-sdk-android-without-mta-x.x.xjar或者wechat-sdk-android-with-mta-x.x.xjar
引入微信支付依赖，android studio的build.gradle文件中，添加如下依赖即可：

3dependencies {
compile 'com.tencent.mm.opensdk:wechat-sdk-android-with-mta:+'
}配置WXPayEntryActivity，从官网demo中copy一个来即可，必须放到app包下新建一个wxapi包里面
AndroidManifest.xml中注册

<!--wx pay-->
<activity

<activity/>发送支付信息给服务端，自定义处理
跳转微信进行支付，java代码大致如下，需要注意的是需要运行到UI主线程，不然Toast.makeText等操作会崩溃

mWXAPI.sendReq(req);
}else{
Toast.makeText(mAppActivity, "生成订单失败", Toast.LENGTH_SHORT).show();
}
}catch(Exception e){
Toast.makeText(mAppActivity, "支付失败"+e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
});
}微信客户端回调支付结果处理，微信会自动回调到继续IWXAPIEventHandler的WXPayEntryActivity::public void onResp(BaseResp resp)，如果在cocos上调用，同样要注意让回调运行在GLThread中

ios接入，参考文献
- 接入流程跟android是一样的，区别的是，一般ios游戏为了上AppStore，一般不接带支付功能的sdk，所以用微信去除支付功能的sdk
将解压的微信OpenSDK文件夹拷贝到项目文件夹下，并导入开发环境中。

4libWeChatSDK.a
WechatAuthSDK.h
WXApi.h
WXApiObject.h并根据官方文档导入依赖库
- 添加URL Schemes, 点击项目名称,点击“Info”选项卡,在“URL Types”选项中,点击“+”, 在“URL Schemes”中输入微信的注册码
使用URLScheme调起weixin

}等待微信回调，头文件中App继承WXApiDelegate，sdk会回调到openURL，但并不会回调到onResp
