**使用方法**

### 1、坐标

Step 1. Add it in your root build.gradle at the end of repositories:
```
allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}
```
Step 2. Add the dependency

```
implementation 'com.github.javen205:JPay:AliPay:latest.release.here'
implementation 'com.github.javen205:JPay:WxPay:latest.release.here'
```

例如：版本号为`0.0.5`

```
implementation 'com.github.javen205.JPay:AliPay:0.0.5'
implementation 'com.github.javen205.JPay:WxPay:0.0.5'
```
### 2. Android Manifest配置

##### 2.1 权限声明

```
 // 最新版本无需特殊配置，已配置到 Library 
```

##### 2.2 注册activity

`application` 节点添加如下类容
```
// 最新版本无需特殊配置，已配置到 Library 
```

### 3. 发起支付

##### 3.1 微信支付

```
com.jpay.wxpay.JPay.getIntance(mContext).toWxPay(appId, partnerId, prepayId, nonceStr, timeStamp, sign, new com.jpay.wxpay.JPay.WxPayListener() {
    @Override
    public void onPaySuccess() {
        Toast.makeText(mContext, "支付成功", Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayError(int error_code, String message) {
        Toast.makeText(mContext, "支付失败>" + error_code + " " + message, Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayCancel() {
        Toast.makeText(mContext, "取消了支付", Toast.LENGTH_SHORT).show();
    }
});
```

或者

```
com.jpay.wxpay.JPay.getIntance(mContext).toWxPay(payParameters, new com.jpay.wxpay.JPay.WxPayListener() {
    @Override
    public void onPaySuccess() {
        Toast.makeText(mContext, "支付成功", Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayError(int error_code, String message) {
        Toast.makeText(mContext, "支付失败>" + error_code + " " + message, Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayCancel() {
        Toast.makeText(mContext, "取消了支付", Toast.LENGTH_SHORT).show();
    }
});
```

`payParameters` 为JSON字符串格式如下：
```
{
  "appId": "",
  "partnerId": "",
  "prepayId": "",
  "sign": "",
  "nonceStr" : "",
  "timeStamp": ""
}
```

或者

```
JPay.getIntance(mContext).toWxPay(appId, partnerId, prepayId, nonceStr, timeStamp, sign, new JPay.JPayListener() {
    @Override
    public void onPaySuccess() {
        Toast.makeText(mContext, "支付成功", Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayError(int error_code, String message) {
        Toast.makeText(mContext, "支付失败>"+error_code+" "+ message, Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayCancel() {
        Toast.makeText(mContext, "取消了支付", Toast.LENGTH_SHORT).show();
    }
});
```
##### 3.2 支付宝支付

```
JPay.getIntance(mContext).toAliPay(orderInfo, new JPay.AliPayListener() {
    @Override
    public void onPaySuccess() {
        Toast.makeText(mContext, "支付成功", Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayError(int error_code, String message) {
        Toast.makeText(mContext, "支付失败>" + error_code + " " + message, Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayCancel() {
        Toast.makeText(mContext, "取消了支付", Toast.LENGTH_SHORT).show();
    }
});
```
##### 3.3 银联支付

```
com.jpay.unionpay.JPay.getIntance(mContext).toUnionPay("01", tn, new com.jpay.unionpay.JPay.UnionPayListener() {
    @Override
    public void onPaySuccess() {
        Toast.makeText(mContext, "支付成功", Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayError(int error_code, String message) {
        Toast.makeText(mContext, "支付失败>" + error_code + " " + message, Toast.LENGTH_SHORT).show();
    }

@Override
    public void onPayCancel() {
        Toast.makeText(mContext, "取消了支付", Toast.LENGTH_SHORT).show();
    }

@Override
    public void onUnionPay(String dataOrg, String sign, String mode) {
        Log.d("onUnionPay", "支付成功>需要后台查询订单确认>dataOrg" + dataOrg + " sign>" + sign + " mode>" + mode);
        Toast.makeText(mContext, "支付成功>需要后台查询订单确认>" + dataOrg + " " + mode, Toast.LENGTH_SHORT).show();
    }
});
```

Activity 中 重写 onActivityResult 监听回调

```
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.e("UnionPay",requestCode+" "+resultCode);
    try {
        UnionPay.getInstance(this).onUnionPayResult(data);
    } catch (JSONException e) {
        e.printStackTrace();
    }
    super.onActivityResult(requestCode, resultCode, data);
}
```

### 4.案例的使用

> appId 以及相关的 key 我们都从服务端获取

#### 4.1 客户端使用说明
 
 1. 将`AndroidManifest.xml` 的包名修改为申请应用的包名
 2. 将应用中的 `build.gradle` 的 `applicationId` 修改为申请应用的包名
 3. 测试的时候修改默认的签名 key

> 将key复制到项目的根目录(app)中并修改 `buildTypes` 配置如下

```
signingConfigs {
    release {
        storeFile file("wxkey")
        storePassword '123456'
        keyAlias '1'
        keyPassword '123456'
    }
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug {
        signingConfig signingConfigs.release
    }
}
```
