记录自己的支付集成（微信支付宝）

首先，作为一个菜鸟表示，虽然网上的集成框架很多，但是我要自己写，就算被坑的死去活来也要自己写。

1. 支付宝

这个支付宝的文档是个好东西，挺简单，挺容易看懂的，其次还有沙箱测试，表示支付宝一次通过很开心。 支付沙箱联调指南

首先导包，这里使用0710的包，提前说明如果使用沙箱需要在支付的activity中添加

EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);

支付的账号和密码去沙箱中获取，支付沙箱联调指南页面的最下方，点击沙箱工具，跳转过后，页面左侧研发服务-沙箱账号

@Overrideprotected void onCreate(Bundle savedInstanceState) {EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);super.onCreate(savedInstanceState);setContentView(R.layout.activity_pay);initView();}

这个直接上代码：ALiPay.java

public class AliPay {// /7/20 沙盒测试通过 代码无误//支付宝支付业务：沙箱使用app_idpublic static final String APPID = "10239552";//支付宝支付业务：沙箱使用RSA2_PRIVATEpublic static final String RSA2_PRIVATE = "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";private static AliPay mAliPay;private Activity mContext;private PayListener mPayListener;private String orderTradeNo;private AliPay(Activity context) {mContext = context;}public static AliPay getInstance(Activity context) {if (mAliPay == null) {synchronized (AliPay.class) {if (mAliPay == null) {mAliPay = new AliPay(context);}}}return mAliPay;}public void startAliPay(final String signOrderInfo, PayListener listener) {mPayListener = listener;Runnable payRunnable = new Runnable() {@Overridepublic void run() {PayTask alipay = new PayTask(mContext);Map<String, String> result = alipay.payV2(signOrderInfo, true);Message msg = new Message();msg.obj = result;mHandler.sendMessage(msg);}};Thread payThread = new Thread(payRunnable);payThread.start();}private Handler mHandler = new Handler(Looper.getMainLooper()) {@SuppressWarnings("unchecked")public void handleMessage(Message msg) {PayResult payResult = new PayResult((Map<String, String>) msg.obj);String resultStatus = payResult.getResultStatus();String resultInfo = payResult.getResult();Log.i("resultinfo", resultInfo);if (mPayListener == null) {return;}// https://doc./doc2/detail.htm?spm=a219a.7629140.0.0.xN1NnL&treeId=204&articleId=105302&docType=1if (payResult == null) {mPayListener.onPayError("结果解析错误");return;}if (TextUtils.equals(resultStatus, "9000")) {//支付成功mPayListener.onPaySuccess();} else if (TextUtils.equals(resultStatus, "8000")) {//正在处理中，支付结果未知（有可能已经支付成功），请查询商户订单列表中订单的支付状态mPayListener.onPayError("正在处理结果中");} else if (TextUtils.equals(resultStatus, "6001")) {//支付取消mPayListener.onPayCancel();} else if (TextUtils.equals(resultStatus, "6002")) {//网络连接出错mPayListener.onPayError("网络连接出错");} else if (TextUtils.equals(resultStatus, "4000")) {//支付错误mPayListener.onPayError("订单支付失败");} else {mPayListener.onPayError(resultInfo);}}};/*** 使用支付宝创建订单信息* 这个签名工作要放在后台服务器中进行处理* 前端将 付订单参数信息 上传到服务器 后台进行签名处理后，将签名后的订单信息发回来** @param itemName* @param itemDescribe* @param itemPrice*/public Map createOrderParamMap(String itemName, String itemDescribe, double itemPrice, String itemTradeNo) {//这里默认使用rsa2私钥Map<String, String> params = buildOrderParamMap(APPID, itemName, itemDescribe, itemPrice, itemTradeNo, true);return params;}public String createOrderInfo(Map<String, String> params) {return buildOrderParam(params);}/*** 构造支付订单参数列表** @param app_id* @param itemName 商品名称* @param itemDecribe 商品详情* @param itemPrice 商品价格* @param rsa2 是否使用rsa2 建议true；* @return*/private Map<String, String> buildOrderParamMap(String app_id, String itemName, String itemDecribe, double itemPrice, String itemTradeNo, boolean rsa2) {Map<String, String> keyValues = new HashMap<String, String>();keyValues.put("app_id", app_id);keyValues.put("biz_content", "{\"timeout_express\":\"30m\",\"product_code\":\"QUICK_MSECURITY_PAY\",\"total_amount\":\"" + itemPrice + "\",\"subject\":\"" + itemName + "\",\"body\":\"" + itemDecribe + "\",\"out_trade_no\":\"" + itemTradeNo + "\"}");keyValues.put("charset", "utf-8");keyValues.put("method", "alipay.trade.app.pay");keyValues.put("sign_type", rsa2 ?

然后自定义一个支付结果接口: PayListener

public interface PayListener {//支付成功void onPaySuccess();//支付失败void onPayError(String resultStatus);//支付取消void onPayCancel();}

然后调用：

注意：

1、这里的signOrderInfo必须要从服务器获取，我的后台这里还是给力的，上传订单id就把signOrderInfo传过来了，都不用自己写，多亏了我的口才。

2、这里的orderInfo是是进行 URLEncoder.encode() 转码的（键为原文，值进行转码），具体内容可以打印出来看下，然后加密sign内容是使用原文（没有进行转码）进行加密

3、这里的Base64.java PayResult.java SignUtils.java 去支付宝的demo中获取（测试阶段）

这里的Base64.java PayResult.java SignUtils.java 去支付宝的demo中获取（测试阶段）

这里的Base64.java PayResult.java SignUtils.java 去支付宝的demo中获取（测试阶段）

这里就是Demo的下载地址了 https://docs./54/104509

自己测试的时候可以这么写：

AliPay aliPay = AliPay.getInstance(this);Map orderParamMap = aliPay.createOrderParamMap("商品名字", "商品描述", 0.01, "123123123123123");String orderInfo = aliPay.createOrderInfo(orderParamMap);String sign = aliPay.getSign(orderParamMap);String signOrderInfo = orderInfo + "&" + sign;AliPay.getInstance(PayActivity.this).startAliPay(signOrderInfo, new PayListener() {@Overridepublic void onPaySuccess() {Comm.Tip(mContext, "支付成功");}@Overridepublic void onPayError(String resultStatus) {Comm.Tip(mContext, "支付失败");}@Overridepublic void onPayCancel() {Comm.Tip(mContext, "支付取消");}});

2.微信支付

微信支付满满的都是坑，特别是官方Demo，看的我头晕，然后还是没弄好，很尴尬。

首先注意一个大坑：我们后台申请接入时候签名填写错误，我就想说ios没有签名，安卓要签名，然后导致了ios成功，安卓失败，我找了一下午的原因。

注意：微信开发平台的申请的应用签名，如果在手机上安装debug包获取的签名，那么只能debug包才能调用微信支付，如果是release包获取的签名，那么只有release包才能调用微信支付，当然，微信开发平台上的签名和包名都是可以更换的。

首先导个包，gradle方式也可以，然而我用AS下不下来，只好导包

简单粗暴上代码：WechatPay.java

public class WechatPay {private static WechatPay wechatPay;private Context mContext;private IWXAPI mIWXAPI;private PayListener mPayListener;private WechatPay(Activity context) {mContext = context;}public static WechatPay getInstance(Activity context) {if (wechatPay == null) {synchronized (WechatPay.class) {if (wechatPay == null) {wechatPay = new WechatPay(context);}}}return wechatPay;}/*** 初始化微信支付接口** @param appId*/public void init(String appId) {mIWXAPI = WXAPIFactory.createWXAPI(mContext, null);mIWXAPI.registerApp(appId);}/*** 获取微信接口** @return*/public IWXAPI getWXApi() {return mIWXAPI;}/*** 调起支付** @param appId* @param partnerId* @param prepayId* @param nonceStr* @param timeStamp* @param sign*/public void startWeChatPay(String appId, String partnerId, String prepayId,String nonceStr, String timeStamp, String sign, PayListener listener) {mPayListener = listener;init(appId);if (!checkWx()) {if (listener != null) {listener.onPayError("未安装微信或者微信版本过低");}return;}PayReq request = new PayReq();request.appId = appId;request.partnerId = partnerId;request.prepayId = prepayId;request.packageValue = "Sign=WXPay";request.nonceStr = nonceStr;request.timeStamp = timeStamp;request.sign = sign;mIWXAPI.sendReq(request);}/*** 响应支付回调** @param error_code* @param message*/public void onResp(int error_code, String message) {if (error_code == 0) {//支付成功mPayListener.onPaySuccess();} else if (error_code == -1) {//支付异常mPayListener.onPayError(message);} else if (error_code == -2) {//支付取消mPayListener.onPayCancel();}mPayListener = null;}//检测微信客户端是否支持微信支付private boolean checkWx() {return isWeixinAvilible() && mIWXAPI.isWXAppInstalled() && mIWXAPI.getWXAppSupportAPI() >= Build.PAY_SUPPORTED_SDK_INT;}/*** 判断微信是否安装** @return*/private boolean isWeixinAvilible() {return appIsAvilible("com.tencent.mm");}/*** 判断app是否安装** @param packageName* @return*/private boolean appIsAvilible(String packageName) {final PackageManager packageManager = mContext.getPackageManager();// 获取packagemanagerList<PackageInfo> pinfo = packageManager.getInstalledPackages(0);// 获取所有已安装程序的包信息if (pinfo != null) {for (int i = 0; i < pinfo.size(); i++) {String pn = pinfo.get(i).packageName;if (pn.equals(packageName)) {return true;}}}return false;}}

其次是：WXPayEntryActivity .java

public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);if (WechatPay.getInstance(this) != null) {WechatPay.getInstance(this).getWXApi().handleIntent(getIntent(), this);} else {finish();}}@Overrideprotected void onNewIntent(Intent intent) {super.onNewIntent(intent);setIntent(intent);if (WechatPay.getInstance(this) != null) {WechatPay.getInstance(this).getWXApi().handleIntent(intent, this);}}@Overridepublic void onReq(BaseReq baseReq) {}@Overridepublic void onResp(BaseResp baseResp) {if (baseResp.getType() == MAND_PAY_BY_WX) {if (WechatPay.getInstance(this) != null) {WechatPay.getInstance(this).onResp(baseResp.errCode, baseResp.errStr);finish();}}}}

再来清单文件中：

改下第二行和最后一行的地址

<!-- 微信 --><activity android:name=".Controller.wxapi.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=".Controller.wxapi.WXPayEntryActivity"/>

好的，现在开始调用：

我的order类当然也是后台发给我的喽

WechatPay.getInstance(PayActivity.this).startWeChatPay(order.getAppid(), order.getPartid(), order.getPrepayid(), order.getNoncestr(), order.getTimestamp(), order.getSign(), new PayListener() {@Overridepublic void onPaySuccess() {Comm.Tip(mContext, "支付成功");}@Overridepublic void onPayError(String resultStatus) {Comm.Tip(mContext, "支付失败");}@Overridepublic void onPayCancel() {Comm.Tip(mContext, "支付取消");}});

好的，打完收工，完成之后发现，其实也就是那么回事。
