支付宝手机网页支付接口调用
1.前期工作
1.1 登陆支付宝官网
网址：https://www.alipay.com/
1.2 下载手机网站支付的demo的步骤
1.2.1 先点击API,选择手机网站支付模块点击
1.2.2 点击SDK&Demo,选择java版本点击下载
1.2.3 点击下载后的文件压缩包
1.2.4 获取的文件接口名
1.3 沙箱准备工作
1.3.1 寻找沙箱的第一步
1.3.2 选择沙箱环境点击
1.3.3 沙箱应用，启动系统默认密钥
1.3.4 沙箱账号：显示买家信息和买家信息，这是支付宝提供的测试的数据
2 导入测试项目
2.1 AlipayConfig文件主要是配置，和沙箱中的商家信息对应，具体配置参考下文
public class AlipayConfig {
// 商户appid
public static String APPID = "";
// 私钥 pkcs8格式的
public static String RSA_PRIVATE_KEY = "";
// 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://商户网关地址/alipay.trade.wap.pay-JAVA-UTF-8/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://商户网关地址/alipay.trade.wap.pay-JAVA-UTF-8/return_url.jsp";
// 请求支付宝网关地址 https://openapi.alipaydev.com/gateway.do（测试环境的网址 alipaydev多个dev,一定别搞错了） 而不是https://openapi.alipay.com/gateway.do（正式环境的网址）
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（切记是支付宝公钥，而不是支付宝应用公钥）
public static String ALIPAY_PUBLIC_KEY = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAjrEVFMOSiNJXaRNKicQuQdsREraftDA9Tua3WNZwcpeXeh8Wrt+V9JilLqSa7N7sVqwpvv8zWChgXhX/A96hEg97Oxe6GKUmzaZRNh0cZZ88vpkn5tlgL4mH/dhSr3Ip00kvM4rHq9PwuT4k7z1DpZAf1eghK8Q5BgxL88d0X07m9X96Ijd0yMkXArzD7jg+noqfbztEKoH3kPMRJC2w4ByVdweWUT2PwrlATpZZtYLmtDvUKG/sOkNAIKEMg3Rut1oKWpjyYanzDgS7Cg3awr1KPTl9rHCazk15aNYowmYtVabKwbGVToCAGK+qQ1gT3ELhkGnf3+h53fukNqRH+wIDAQAB";
// 日志记录目录
public static String log_path = "/log";
// RSA2
public static String SIGNTYPE = "RSA2";
}
2.2 访问支付宝电脑网站支付体验入口页 index.jsp
访问链接：http://127.0.0.1:8080/alipay.trade.wap.pay-java-utf-8/index.jsp
2.3 点击订单查询
