android支付之支付宝支付
先导入jar包alipaySDK-20150818
调用支付宝
AlipayUtils.pay(this,mHandler,"订单信息","订单描述","0.01");
接收支付宝的返回结果
/** * 接收支付宝的返回结果 */ private Handler mHandler = new Handler() { public void handleMessage(Message msg) { switch (msg.what) { case ConstantValues.SDK_PAY_FLAG: { PayResult payResult = new PayResult((String) msg.obj); // 支付宝返回此次支付结果及加签，建议对支付宝签名信息拿签约时支付宝提供的公钥做验签 String resultInfo = payResult.getResult(); String resultStatus = payResult.getResultStatus(); if (TextUtils.equals(resultStatus, "9000")) { Toast.makeText(MainActivity.this,"支付成功",Toast.LENGTH_SHORT).show(); } else { if (TextUtils.equals(resultStatus,"8000")) { Toast.makeText(MainActivity.this,"支付结果确认中",Toast.LENGTH_SHORT).show(); } else if (TextUtils.equals(resultStatus,"6001")){ Toast.makeText(MainActivity.this,"您取消了订单支付",Toast.LENGTH_SHORT).show(); }else if (TextUtils.equals(resultStatus,"6002")){ Toast.makeText(MainActivity.this,"网络连接出错",Toast.LENGTH_SHORT).show(); }else { Toast.makeText(MainActivity.this,"支付失败",Toast.LENGTH_SHORT).show(); } } break; } default: break; } }; };
以上是在支付页面中的调用↑
下面是几个必须的页面(类名不要改)
1、Base64

2、PayResult
import android.text.TextUtils; public class PayResult { private String resultStatus; private String result; private String memo; public PayResult(String rawResult) { if (TextUtils.isEmpty(rawResult)) return; String[] resultParams = rawResult.split(";"); for (String resultParam : resultParams) { if (resultParam.startsWith("resultStatus")) { resultStatus = gatValue(resultParam, "resultStatus"); } if (resultParam.startsWith("result")) { result = gatValue(resultParam, "result"); } if (resultParam.startsWith("memo")) { memo = gatValue(resultParam, "memo"); } } } @Override public String toString() { return "resultStatus={" + resultStatus + "};memo={" + memo + "};result={" + result + "}"; } private String gatValue(String content, String key) { String prefix = key + "={"; return content.substring(content.indexOf(prefix) + prefix.length(), content.lastIndexOf("}")); } /** * @return the resultStatus */ public String getResultStatus() { return resultStatus; } /** * @return the memo */ public String getMemo() { return memo; } /** * @return the result */ public String getResult() { return result; } }
3、SignUtils
import java.security.KeyFactory; import java.security.PrivateKey; import java.security.spec.PKCS8EncodedKeySpec; public class SignUtils { private static final String ALGORITHM = "RSA"; private static final String SIGN_ALGORITHMS = "SHA1WithRSA"; private static final String DEFAULT_CHARSET = "UTF-8"; public static String sign(String content, String privateKey) { try { PKCS8EncodedKeySpec priPKCS8 = new PKCS8EncodedKeySpec( Base64.decode(privateKey)); KeyFactory keyf = KeyFactory.getInstance(ALGORITHM); PrivateKey priKey = keyf.generatePrivate(priPKCS8); java.security.Signature signature = java.security.Signature .getInstance(SIGN_ALGORITHMS); signature.initSign(priKey); signature.update(content.getBytes(DEFAULT_CHARSET)); byte[] signed = signature.sign(); return Base64.encode(signed); } catch (Exception e) { e.printStackTrace(); } return null; } }
4、AlipayUtils
import java.io.UnsupportedEncodingException; import java.net.URLEncoder; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Locale; import java.util.Random; import android.os.Handler; import android.os.Message; import com.alipay.sdk.app.PayTask; import com.xh.boke.ConstantValues; import com.xh.boke.base.BaseActivity; /** * 支付宝支付工具类 * Created by Administrator on 2015/10/23 0023. */ public class AlipayUtils { /** * call alipay sdk pay. 调用SDK支付 */ public static void pay(final BaseActivity activity,final Handler handler,String title,String desc,String price) { // 订单 String orderInfo = getOrderInfo(title,desc,price); // 对订单做RSA 签名 String sign = sign(orderInfo); try { // 仅需对sign 做URL编码 sign = URLEncoder.encode(sign, "UTF-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } // 完整的符合支付宝参数规范的订单信息 final String payInfo = orderInfo + "&sign=\"" + sign + "\"&" + getSignType(); Runnable payRunnable = new Runnable() { @Override public void run() { // 构造PayTask 对象 PayTask alipay = new PayTask(activity); // 调用支付接口，获取支付结果 String result = alipay.pay(payInfo); Message msg = new Message(); msg.what = ConstantValues.SDK_PAY_FLAG; msg.obj = result; handler.sendMessage(msg); } }; // 必须异步调用 Thread payThread = new Thread(payRunnable); payThread.start(); } /** * check whether the device has authentication alipay account. * 查询终端设备是否存在支付宝认证账户 * */ public static void check(final BaseActivity activity,final Handler handler) { Runnable checkRunnable = new Runnable() { @Override public void run() { // 构造PayTask 对象 PayTask payTask = new PayTask(activity); // 调用查询接口，获取查询结果 boolean isExist = payTask.checkAccountIfExist(); Message msg = new Message(); msg.what = ConstantValues.SDK_CHECK_FLAG; msg.obj = isExist; handler.sendMessage(msg); } }; Thread checkThread = new Thread(checkRunnable); checkThread.start(); } /** * create the order info. 创建订单信息 * */ public static String getOrderInfo(String subject, String body, String price) { // 签约合作者身份ID String orderInfo = "partner=" + "\"" + ConstantValues.PARTNER + "\""; // 签约卖家支付宝账号 orderInfo += "&seller_id=" + "\"" + ConstantValues.SELLER + "\""; // 商户网站唯一订单号 orderInfo += "&out_trade_no=" + "\"" + getOutTradeNo() + "\""; // 商品名称 orderInfo += "&subject=" + "\"" + subject + "\""; // 商品详情 orderInfo += "&body=" + "\"" + body + "\""; // 商品金额 orderInfo += "&total_fee=" + "\"" + price + "\""; // 服务器异步通知页面路径 orderInfo += "¬ify_url=" + "\"" + "http://notify.msp.hk/notify.htm" + "\""; // 服务接口名称， 固定值 orderInfo += "&service=\"mobile.securitypay.pay\""; // 支付类型， 固定值 orderInfo += "&payment_type=\"1\""; // 参数编码， 固定值 orderInfo += "&_input_charset=\"utf-8\""; // 设置未付款交易的超时时间 // 默认30分钟，一旦超时，该笔交易就会自动被关闭。 // 取值范围：1m～15d。 // m-分钟，h-小时，d-天，1c-当天（无论交易何时创建，都在0点关闭）。 // 该参数数值不接受小数点，如1.5h，可转换为90m。 orderInfo += "&it_b_pay=\"30m\""; // extern_token为经过快登授权获取到的alipay_open_id,带上此参数用户将使用授权的账户进行支付 // orderInfo += "&extern_token=" + "\"" + extern_token + "\""; // 支付宝处理完请求后，当前页面跳转到商户指定页面的路径，可空 orderInfo += "&return_url=\"m.alipay.com\""; // 调用银行卡支付，需配置此参数，参与签名， 固定值 （需要签约《无线银行卡快捷支付》才能使用） // orderInfo += "&paymethod=\"expressGateway\""; return orderInfo; } /** * get the out_trade_no for an order. 生成商户订单号，该值在商户端应保持唯一（可自定义格式规范） * */ public static String getOutTradeNo() { SimpleDateFormat format = new SimpleDateFormat("MMddHHmmss", Locale.getDefault()); Date date = new Date(); String key = format.format(date); Random r = new Random(); key = key + r.nextInt(); key = key.substring(0, 15); return key; } /** * sign the order info. 对订单信息进行签名 * * @param content * 待签名订单信息 */ public static String sign(String content) { return SignUtils.sign(content, ConstantValues.RSA_PRIVATE); } /** * get the sign type we use. 获取签名方式 * */ public static String getSignType() { return "sign_type=\"RSA\""; } }
下面是支付宝商户的配置信息
/** * 常量 * Created by Administrator on 2015/10/23 0023. */ public class ConstantValues { /** 支付宝支付 */ //商户PID public static final String PARTNER = ""; //商户收款账号 public static final String SELLER = ""; //商户私钥，pkcs8格式 public static final String RSA_PRIVATE = ""; //支付宝公钥 public static final String RSA_PUBLIC = ""; public static final int SDK_PAY_FLAG = 1; public static final int SDK_CHECK_FLAG = 2; }
获取公钥和私钥
2、如何上传公钥
另外，在Android Manifest.xml 里面加上这句，在没有安装支付宝的情况下可以跳转一个H5页面进行支付
<!--没安装支付宝时弹出的支付页面--> <activity android:name="com.alipay.sdk.app.H5PayActivity" android:configChanges="orientation|keyboardHidden|navigation" android:exported="false" android:screenOrientation="behind" android:windowSoftInputMode="adjustResize|stateHidden" > </activity>
