Android开发支付集成——支付宝集成

微信支付传送门：https://www.cnblogs.com/dingxiansen/p/9209159.html

 一、支付宝支付

1. 支付宝支付流程图

2. 集成前准备

1. 去蚂蚁金服注册应用获取appKey等信息
2. 创建应用，添加APP支付功能
3. 找到APP支付开发文档，下载 SDK&Demo

3. 开始集成

　　1、导入Demo中需要用到的Jar包

　　2、配置AndroidManifest.xml(这里直接放常用的权限)

 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.READ_LOGS" /><uses-permission android:name="android.permission.VIBRATE" /><uses-permission android:name="android.permission.WAKE_LOCK" /><uses-permission android:name="android.permission.WRITE_SETTINGS" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" /><uses-permission android:name="android.permission.GET_TASKS" /><uses-permission android:name="android.permission.RECEIVE_SMS" /><uses-permission android:name="android.permission.READ_SMS" /><uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

支付回调

<activityandroid:name="com.alipay.sdk.app.H5PayActivity"android:configChanges="orientation|keyboardHidden|navigation"android:exported="false"android:screenOrientation="behind" /><activityandroid:name="com.alipay.sdk.auth.AuthActivity"android:configChanges="orientation|keyboardHidden|navigation"android:exported="false"android:screenOrientation="behind" />

3、请求后台接口拿到签过名的信息(appKey,订单信息等等)，这里我获取数据，是直接给后台传递的商品id，如果有的需要商品数量直接给传给后台，后台根据id查询出商品的信息，然后返回给前台所需要的支付参数。

　　支付宝返回参数用例(开始集成的时候看过好多博客都没有返回参数数据结构，结果一脸懵逼，在这里贴出，未加密之前的0.0)：

格式化后的：

{"msg":"success","code":200,"data":"alipay_sdk=alipay-sdk-java-dynamicVersionNo&app_id=你们申请的app_id&biz_content=%7B%22out_trade_no%22%3A%22HY201806210002%22%2C%22product_code%22%3A%22QUICK_MSECURITY_PAY%22%2C%22subject%22%3A%22%E4%BC%98%E9%93%BA%E4%BC%9A%E5%91%98%E6%9C%8D%E5%8A%A1%E8%B4%B9%22%2C%22total_amount%22%3A%220.01%22%7D&charset=UTF-8&format=json&method=alipay.trade.app.pay¬ify_url=http%3A%2F%2F你们的回调地址%2FaliPayCallBack%2FcallBack&sign=buipaoj2F8xl5XCAUVoJz%2Fbh8dHbaoRmdzoAEzqKRJqtZATT4bfFdzSHurAAL5C5gvntFrDTGHgNRGw%2BNZBtG4DfetOzcpHMAyjslrmUIMIr1YGC7Qya04mFBCh%2B0UIa1E7RISZWSbIVCHpZISknNgF2oTuTixNosXvDXzkGYGBUoaxdh1f6%2F%2Bw9lqKz7mkhsUc0x8lCeJHw4MnTS4gSLU%2BDmOCk6Tkiwb4Yv4Mz%2F6j7XReeagfX7qxs5qbObnnPX%2FFmu9T%2BF0LwJaPxr5Xys8kr8E4bhd4f7Y5FimXiw%2BG7EFkY0I69boiRob7zo%2BbWQ%2F53TAMeTXX5RJybEdXhrA%3D%3D&sign_type=RSA2×tamp=2018-06-21+14%3A11%3A40&version=1.0","status":"0"
}

后台返回信息之后接下来就是我们的事情了，调起支付宝进行支付

 /*支付宝测试*/private void testZfbPay(final String key, final String value) {StringRequest stringRequest = new StringRequest(Request.Method.POST, NetWorkUrl.ZFBPAY, new Response.Listener() {@RequiresApi(api = Build.VERSION_CODES.M)@Overridepublic void onResponse(String s) {Log.e("GoPayOrderActivity", "-------getJson2-------" + s.toString());/*判断code*/String code = (JSONObject.parseObject(s.toString()).getString("code"));if (code.equals("200")) {String orderInfo = (JSONObject.parseObject(s.toString()).getString("data"));//返回的信息MyALipayUtils.ALiPayBuilder builder = new MyALipayUtils.ALiPayBuilder();builder.build().toALiPay(GoPayOrderActivity.this, orderInfo);}}}, new Response.ErrorListener() {@Overridepublic void onErrorResponse(VolleyError volleyError) {}}) {@Overridepublic Map getParams() throws AuthFailureError {Log.e("GoPayOrderActivity", "getParams:-----------------> " + userEntity.getPhone());Map map = new HashMap();map.put("account", userEntity.getPhone());map.put(key, value);map.put("token", userEntity.getToken());return map;}@Overridepublic Map getHeaders() throws AuthFailureError {HashMap headers = new HashMap();if (userEntity.getToken().equals("") && userEntity != null) {headers.put("Authorization", userEntity.getToken());}return headers;}};/*设置请求一次*/stringRequest.setRetryPolicy(new DefaultRetryPolicy(5000,//默认超时时间，应设置一个稍微大点儿的，例如本处的500000DefaultRetryPolicy.DEFAULT_MAX_RETRIES,//默认最大尝试次数
                        DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));AppApplication.getHttpQueues().add(stringRequest);/*请求数据*/}

MyALipayUtils.java这个类直接copy使用就可以

/*** Created by dingchao on 2018/3/20.*/public class MyALipayUtils {private static final int SDK_PAY_FLAG = 1;private Activity context;private ALiPayBuilder builder;private MyALipayUtils(ALiPayBuilder builder) {this.builder = builder;}private Handler mHandler = new Handler() {public void handleMessage(Message msg) {//            返回码    含义

}

完成上述操作，你的app在蚂蚁金服后台应用上线之后，就完全可以调用支付了，但是在开发阶段，应用没有上线，你是不能进行调试的，所以支付宝有沙箱模式可以进行调试，ios没有哟

进行沙箱调试在Activity的的onCreate()方法中添加

EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);//支付宝沙箱环境，正式需注释

别忘了让你们后台把appKey等信息换成沙箱的，然后测试支付的时候，需要下载一个沙箱支付宝，这个你可以随意支付，附上链接

沙箱首页：https://sandbox.alipaydev.com/user/accountDetails.htm?currentBar=1

App支付接入文档:https://docs.open.alipay.com/204/105051

沙箱钱包下载：

调试都没有问题之后，就可以在蚂蚁金服开发者平台进行应用上线，然后沙箱代码就可以注释了，这样支付宝支付就接入完成
