支付宝H5支付demo

支付宝H5支付

首先我们必须注册一个支付宝应用（本案例就直接用支付宝的沙箱环境，这个沙箱也就是支付宝提供给开发者的一个测试环境）

登录地址：https://open.alipay.com/platform/home.htm

1、怎么注册一个支付宝应用？看图（至于应用里面需要的资料你就跟着填就ok了，我就不多讲了，关于公钥秘钥这些，支付宝也有它自己的工具自动生成）

2、怎么获取沙箱环境？（看图）

就这样，支付宝的基本配置我们都能get到了，下面开始写代码吧！

3、思路描述

支付宝的h5支付比微信的h5支付简单很多，下面先跟大家看看项目文件数量吧

就7个文件左右就可以实现支付了，是不是很简单呢？（下一篇是微信h5就没有那么简单了）

接着我说说里面每个文件他们的作用后再看代码吧！！！

AlipayConfig.java 　　　----------------------------用于存储支付宝的相关配置信息

AlinotifyServlet.java　　 ----------------------------用于支付后，返回的结果，接着做你的对应业务的

AlipayServlet.java　　　----------------------------用于实现支付操作

logFile.java　　　　　　----------------------------用于打印日志

Constants.java　　　　 ----------------------------用于存储常量

index.jsp　　　　　　　----------------------------用于用户发起支付请求

return_jsp.jsp　　　　　---------------------------用于支付后返回的页面

好，现在开始代码展示：

首先要配置AlipayConfig.java （这些参数我现在用的都是沙箱环境的）

package fe.client.pay.alipay.config;

import fe.client.pay.tool.Constants;

public class AlipayConfig {
    // 商户appid
    public static String APPID = "2017092077552049";
    // 私钥 pkcs8格式的
    public static String RSA_PRIVATE_KEY = "greterthhoihrhigfdhouiihgfdooihrroihhigdshgfdfoihgdhgfdkjlnfdbknunifdhugfhidfhglkfdvkjlfilhfdiohrewiouihvfbkjnvfdbkjncdhkjoihfdi3uy9283hjdofhgghnxociby98knlknsdkljfsdlkfsdjsdjoflsdjfsldgfjsdf";
    // 服务器异步通知页面路径 需http://或者https://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问
    public static String notify_url = "http://"+Constants.SERVER_ADDRESS+"/goshop/notify_url.jsp";
    // 页面跳转同步通知页面路径 需http://或者https://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问 商户可以自定义同步跳转地址
    public static String return_url = "http://"+Constants.SERVER_ADDRESS+"/goshop/return_url.jsp";
    // 请求网关地址
    public static String URL = "https://openapi.alipaydev.com/gateway.do";
    // 编码
    public static String CHARSET = "UTF-8";
    // 返回格式
    public static String FORMAT = "json";
    // 支付宝公钥
    public static String ALIPAY_PUBLIC_KEY = "qazwsxdedcfrfvgytghbnujikfgvbbyujikjgfgfiuouyfugbgikbnojopih";
    // 日志记录目录
    public static String log_path = "/log";
    // RSA2
    public static String SIGNTYPE = "RSA2";
}

Constants.java

package fe.client.pay.tool;

/**
 * 该类专门用于存储项目中用到的常量类
 * ClassName: Constants
 * @Description: TODO
 * @author 邝梓荣
 * @date 2018-11-21
 */
public class Constants {

    //服务器地址
    public final static String SERVER_ADDRESS = "127.0.0.1";
//    public final static String SERVER_ADDRESS = "www.wigoule.com";

    //上传时读到服务器内存中设定的限制(与服务器配置成正比 与同时上传的人数成反比关系)
    public final static int SIZE_THRESHOLD = 64*1024;

    //3des加密24字节秘钥
    public final static byte[] keyBytes = {0x11, 0x22, 0x4F, 0x58, (byte)0x88, 0x10, 0x40, 0x38
            , 0x28, 0x25, 0x79, 0x51, (byte)0xCB, (byte)0xDD, 0x55, 0x66
            , 0x77, 0x29, 0x74, (byte)0x98, 0x30, 0x40, 0x36, (byte)0xE2}; 

}

logFile.java

package fe.client.pay.alipay.util;

import java.io.FileWriter;
import java.io.IOException;

import fe.client.pay.alipay.config.AlipayConfig;

public class logFile {
     /**
     * 写日志，方便测试（看网站需求，也可以改成把记录存入数据库）
     * @param sWord 要写入日志里的文本内容
     */
    public static void logResult(String sWord) {
        FileWriter writer = null;
        try {
            writer = new FileWriter(AlipayConfig.log_path + "alipay_log_" + System.currentTimeMillis()+".txt");
            writer.write(sWord);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (writer != null) {
                try {
                    writer.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
