RxPay: A Kotlin repository from Cuiernao

What's RxPay ?

让支付从此简单下去，一键支付功能，支持支付宝支付，微信支付

使用步骤

step 1（Gradle）

java 项目配置

dependencies {
    	compile 'com.cuieney:rxpay-api:2.1.6'
    	annotationProcessor 'com.cuieney:rxpay-compiler:2.1.1'
        //如果你项目配置了kotlin请忽略下面这行的配置（否则会报错 Failed resolution of: Lkotlin/jvm/internal/Intrinsics）
        compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
}

kotlin 项目配置


apply plugin: 'kotlin-kapt'

dependencies {
    compile 'com.cuieney:rxpay-api:2.1.6'
    kapt 'com.cuieney:rxpay-compiler:2.1.1'
    ...
}

step 2

在你的AndroidManifest文件中添加权限

AndroidManifest


<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" />

step 3

如果你需要用到微信支付的话，请仔细看一下步骤 1.在你要使用微信支付的地方添加一下注解

@WX(packageName = "微信支付注册keystore时候的包名")
public class MainActivity extends AppCompatActivity

2.在AndroidManifest添加你微信支付的appid 和商户号，apiKey（商户平台设置的密钥key）

   <meta-data
            android:name="WX_APPID"
            android:value="xxxxx"/>
   //非必填项，此处填写后，请求json的partnerId字段就可以不填
   <meta-data
            android:name="PARTNER_ID"
            android:value="xxxx"/>
    //非必填项，此处填写后，请求json的sign字段就可以不填（即App端签名）
   <meta-data
            android:name="API_KEY"
            android:value="xxxxx"/>

3.在AndroidManifest的微信支付回调页面的Activity

     <activity
            android:name="xxx.xxx.xxx.wxapi.WXPayEntryActivity"
            android:exported="true"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="adjustPan"
            />

上面的xxx.xxx.xxx就是你微信支付注册keystore时候的包名，报错没关系，编译会生成对应的Activity。

对应的支付宝支付AndroidManifest需要添加的是

<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>

step 4

发起支付功能

1.发起支付宝支付请求

 rxPay.requestAlipay("服务器产生的订单信息")
                .subscribe(new Consumer<Boolean>() {
                    @Override
                    public void accept(Boolean aBoolean) throws Exception {
                        payState.setText("阿里支付状态："+aBoolean);
                    }
                }, new Consumer<Throwable>() {
                    @Override
                    public void accept(Throwable throwable) throws Exception {
                        payState.setText("阿里支付状态："+throwable.getMessage());
                    }
                });

2.发起微信支付请求

 rxPay.requestWXpay(new JSONObject(“服务器生成订单的后拼接成下图这种json”))
                .subscribe(new Consumer<Boolean>() {
                    @Override
                    public void accept(Boolean aBoolean) throws Exception {
                        payState.setText("微信支付状态："+aBoolean);
                    }
                }, new Consumer<Throwable>() {
                    @Override
                    public void accept(Throwable throwable) throws Exception {
                        payState.setText("微信支付状态："+throwable.getMessage());
                    }
                });

对应的json格式参考

{
    "nonceStr": "非必填项",
    "partnerId": "非必填项(如果不填此选项，必须在AndroidManifest配置PARTNER_ID)",
    "packageValue": "非必填项",
    "prepayId": "必填项",
    "sign": "非必填项（如果不填此选项，必须在AndroidManifest配置API_KEY）",
    "timeStamp": "非必填项"
}

code sample

混淆

-keep class com.alipay.android.app.IAlixPay{*;}
-keep class com.alipay.android.app.IAlixPay$Stub{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback$Stub{*;}
-keep class com.alipay.sdk.app.PayTask{ public *;}
-keep class com.alipay.sdk.app.AuthTask{ public *;}
-keep class com.alipay.sdk.app.H5PayCallback {
    <fields>;
    <methods>;
}
-keep class com.alipay.android.phone.mrpc.core.** { *; }
-keep class com.alipay.apmobilesecuritysdk.** { *; }
-keep class com.alipay.mobile.framework.service.annotation.** { *; }
-keep class com.alipay.mobilesecuritysdk.face.** { *; }
-keep class com.alipay.tscenter.biz.rpc.** { *; }
-keep class org.json.alipay.** { *; }
-keep class com.alipay.tscenter.** { *; }
-keep class com.ta.utdid2.** { *;}
-keep class com.ut.device.** { *;}

-dontwarn com.alipay.android.phone.mrpc.core.**

Tips

如果你的项目中有之前集成了支付宝，请记得删除了alipaySdk-xxxxxxxx.jar，不然会冲突。
对于调起微信支付的json的字段请参考以上的json
如果项目中还有Rxjava版本1的话为了防止代码冲突请在build.gradle里面添加一下代码

 packagingOptions {
        exclude 'META-INF/rxjava.properties'
    }
