支付宝沙箱支付——傻瓜教程

谁借莪１个温暖的怀抱￠ 2022-09-05 14:53 284阅读 0赞

个人网站想要接入支付，没有企业资质没办法接入。但是可以用沙箱支付测试一下。

**1.进入[支付宝开放平台][Link 1]首页，往下拉找到开发服务 > 沙箱**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mzk1MjczNg_size_16_color_FFFFFF_t_70]

**2.点击开放平台控制器，登录，进入研发服务**

**3.如上图所示，我们需要设置RSA2**

作用：  
**RSA非对称**  
发起支付：商户（商户应用私钥签名） -> 支付宝（商户应用公钥验签）  
异步通知：支付宝（支付宝私钥签名） -> 商户（支付宝公钥验签）

**4.点击进入[RSA应用私钥生成页面][RSA]复制应用公钥。**  
回到上一张图那里，点开设置RSA2，粘贴应用公钥，生成支付宝公钥

**5.IDEA新建项目pay，导入如下依赖**

<dependency>
                <groupId>com.alipay.sdk</groupId>
                <artifactId>alipay-sdk-java</artifactId>
                <version>4.16.2.ALL</version>
            </dependency>

新建controller，并创建类PayController，看下面注意事项

package com.jiafa.pay.controller;
    
    import com.alipay.api.AlipayApiException;
    import com.alipay.api.AlipayClient;

            for (Iterator<String> iter = requestParams.keySet().iterator(); iter.hasNext();) {
        
                String name = (String) iter.next();
                String[] values = (String[]) requestParams.get(name);
                String valueStr = "";
                for (int i = 0; i < values.length; i++) {
        
                    valueStr = (i == values.length - 1) ? valueStr + values[i] : valueStr + values[i] + ",";
                }
                // 乱码解决，这段代码在出现乱码时使用
                valueStr = new String(valueStr.getBytes("utf-8"), "utf-8");
                params.put(name, valueStr);
            }
    
            System.out.println(params);//查看参数都有哪些
            boolean signVerified = AlipaySignature.rsaCheckV1(params, ALIPAY_PUBLIC_KEY, CHARSET, SIGN_TYPE); // 调用SDK验证签名

                System.out.println("支付宝交易号="+trade_no);
                System.out.println("付款金额="+total_amount);
    
                //支付成功，修复支付状态

                return "ok";//跳转付款成功页面
            }else{
        
                return "no";//跳转付款失败页面
            }
        }
    }

修改**APP\_ID**、**APP\_PRIVATE\_KEY**（应用私钥）、**ALIPAY\_PUBLIC\_KEY**（支付宝公钥）、**NOTIFY\_URL**（异步通知路径，必须是公网地址，如果没有公网地址怎么办？等等下面介绍一个内网穿透的办法。）、**RETURN\_URL**，还有这里被我写死了，也可以通过查询orderId，获取Order对象，再写入信息。

这些信息改完就差不多了，我们来看一下内网穿透吧。

**6.打开[natapp][]网站，下载客户端。**  
需要购买隧道，咱们买个9元/月的就可以了

点开右边的配置，写上地址和端口号  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mzk1MjczNg_size_16_color_FFFFFF_t_70 8]  
**7.打开刚刚下载的客户端，运行exe文件**  
![在这里插入图片描述][1d07c8265392427c97231e49dccc8259.png]

**8. 运行pay项目。访问以下路径：**  
http://fafa-xxxx.natapp1.cc/pay/alipay?orderId=112  
显示支付界面  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mzk1MjczNg_size_16_color_FFFFFF_t_70 10]  
在刚刚配置RSA2那里有个沙箱账号，根据这个填入卖家信息即可。

**9.下载沙箱钱包，用上图的卖家账号和密码登录，能看到支付记录。**

**10.完成，配置成功点个赞噢。**
