# 微信支付无法获取结果回调，正在修复

# 注意事项

1. 当前项目依赖Qmui 1.0.7，即在主项目中配置了Qmui，quicklib中的样式无需再次配置就与主项目中的样式一致，后期可能会脱离出来

# 本项目中的支付与二维码模块clone自RxTools

## 支付工具类
### 支付宝支付:

AliPayTools.aliPay(mContext,
APP_ID,//支付宝分配的APP_ID
isRSA2,//是否是 RSA2 加密
RSA_PRIVATE,// RSA 或 RSA2 字符串
new AliPayModel(order_id,//订单ID (唯一)
money,//价格
name,//商品名称
detail),//商品描述详情 (用于显示在 支付宝 的交易记录里)
new onRequestListener() {
@Override
public void onSuccess(String s) {RxToast.success("支付成功");}

@Override
public void onError(String s) {RxToast.error("支付失败");
}
});

### 微信支付:

> 第一种情景: 支付操作全部在APP端完成(包括统一下单接口) 即支付过程无后台参与
WechatPayTools.wechatPayUnifyOrder(mContext,
WX_APP_ID, //微信分配的APP_ID
WX_PARTNER_ID, //微信分配的 PARTNER_ID (商户ID)
WX_PRIVATE_KEY, //微信分配的 PRIVATE_KEY (私钥)
new WechatModel(order_id, //订单ID (唯一)
money, //价格
name, //商品名称
detail), //商品描述详情
new onRequestListener() {
@Override
public void onSuccess(String s) {}

@Override
public void onError(String s) {}
});

> 第二种情景: 从后台获取到 prepayid（预支付订单ID） 之后,在App端进行支付操作
wechatPayApp(mContext,
app_id, //微信分配的APP_ID
partner_id, //微信分配的 PARTNER_ID (商户ID)
wx_private_key, //微信分配的 PRIVATE_KEY (私钥)
prepay_id, //订单ID (唯一)
new onRequestListener() {
@Override
public void onSuccess(String s) {}

@Override
public void onError(String s) {}
});

### 微信分享:

> 分享网页
WechatShareTools.init(mContext, WX_APP_ID);//初始化

String url = "https://github.com/vondear/RxTools";//网页链接

String description = "工欲善其事必先利其器！";//描述

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);//获取Bitmap
byte[] bitmapByte = RxImageTool.bitmap2Bytes(bitmap, Bitmap.CompressFormat.PNG);//将 Bitmap 转换成 byte[]

mWechatShareModel = new WechatShareModel(url, "APP名称", description, bitmapByte);

//Friend 分享微信好友,Zone 分享微信朋友圈,Favorites 分享微信收藏
WechatShareTools.shareURL(mWechatShareModel, WechatShareTools.SharePlace.Friend);//分享操作
