JPay

对微信App支付、支付宝App支付的二次封装,对外提供一个相对简单的接口以及支付结果的回调

oschina:http://git.oschina.net/javen205/JPay

使用方法

1、坐标

compile 'com.jpay:jpaysdk:latest.release.here'

或者 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

compile 'com.github.javen205.JPay:jpaylib:0.0.3'

2. Android Manifest配置

2.1权限声明

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2.2注册activity

application节点添加如下类容

 <!-- 微信支付 -->
        <activity
            android:name="com.jpay.weixin.WXPayEntryActivity"
            android:configChanges="orientation|keyboardHidden|navigation|screenSize"
            android:launchMode="singleTop"
            android:theme="@android:style/Theme.Translucent.NoTitleBar" />
        <activity-alias
            android:name=".wxapi.WXPayEntryActivity"
            android:exported="true"
            android:targetActivity="com.jpay.weixin.WXPayEntryActivity" />
        <!-- 微信支付 end -->


        <!-- alipay sdk begin -->

        <activity
            android:name="com.alipay.sdk.app.H5PayActivity"
            android:configChanges="orientation|keyboardHidden|navigation|screenSize"
            android:exported="false"
            android:screenOrientation="behind"
            android:windowSoftInputMode="adjustResize|stateHidden" >
        </activity>
        <activity
            android:name="com.alipay.sdk.app.H5AuthActivity"
            android:configChanges="orientation|keyboardHidden|navigation"
            android:exported="false"
            android:screenOrientation="behind"
            android:windowSoftInputMode="adjustResize|stateHidden" >
        </activity>

        <!-- alipay sdk end -->

3. 发起支付

3.1 微信支付

JPay.getIntance(mContext).toPay(JPay.PayMode.WXPAY, payParameters, 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();
			}
		});

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).toPay(JPay.PayMode.ALIPAY, orderInfo, 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();
			}
		});

或者

Alipay.getInstance(mContext).startAliPay(orderInfo, new JPay.JPayListener() {
			@Override
			public void onPaySuccess() {

			}

			@Override
			public void onPayError(int error_code, String message) {

			}

			@Override
			public void onPayCancel() {

			}
		});

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

将AndroidManifest.xml 的包名修改为申请应用的包名
将应用中的build.gradle的 applicationId修改为申请应用的包名
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
        }
    }
