支付宝支付接口的使用

今天药忘吃喽~ 2022-06-13 02:06 364阅读 0赞

首先当然是将支付宝封装好的接口的jar包导入到项目当中，文件地址

支付宝提供了沙箱模式，可以在开发的时候通过假的账号密码来进行测试，这点比微信好多了。并且支付宝的支付接口使用起来比微信简单很多。这纯属个人感觉，还希望有人能指点微信支付的接口的时候。

## 支付宝支付前期配置 ##

下面我们到支付宝的支付接口网站[https://openhome.alipay.com/][https_openhome.alipay.com]  
登陆后点击首页可以看到如下  
![页面][SouthEast 1]  
点击左面的加号看到弹出下面![窗口][SouthEast 2]  
可以看到有沙箱应用，沙箱账号，沙箱工具。接下来的测试都是使用沙箱 来完成的，点击加号添加到自己的工具中。  
然后点击沙箱应用，在跳转的页面申请沙箱应用，具体细节按照提示完成即可 ，沙箱应用页面申请完成之后填写相应的数据  
![这里写图片描述][SouthEast 3]  
只需要填写必看部分即可，填写RSA2就不用填写RSA了 填写的数据需要我们使用一个工具来完成，也是支付宝提供的，在上面的链接中都有。  
![这里写图片描述][SouthEast 4]  
使用bat文件打开工具  
![这里写图片描述][SouthEast 5]  
按照图中的样式选中，然后点击生成密钥，密钥分成公钥和私钥。  
这里的公钥是在支付宝网站中设置应用使用，密钥是在我们java程序中配置支付参数的时候使用，所以都要保留。  
上面生成的公钥我们复制下来  
RSA2(SHA256)密钥(推荐)  
![中][SouthEast 6]  
点击查看应用公钥，将用具生成的应用公钥粘贴进去  
![这里写图片描述][SouthEast 7]  
完成后，页面中的查看支付宝公钥也会自动生成，在后面会使用。  
然后就配置完成了。现在我们在点击页面左侧菜单中的沙箱账号，  
![这里写图片描述][SouthEast 8]  
可以看到给了我们一个商家账号，一个买家账号。下面的所有支付过程都要使用这两个账号来完成。到此网站上的设置就完成了。

## java程序中进行开发 ##

将jar包导入到项目中后，我们需要创建一个配置类

package com.yssoft.fs.supervise.web.test;
    
    
    import org.springframework.stereotype.Component;
    
    import com.alipay.api.AlipayClient;
    import com.alipay.api.DefaultAlipayClient;
    
    /** * 支付配置类 * @author cheny * */
    @Component
    public class TestPayConfiguration { 
    
        /** API调用客户端 */
        private static AlipayClient alipayClient;
    
    
        public static AlipayClient success(){
            //服务地址测试都使用这个不用改
            String serverUrl="https://openapi.alipaydev.com/gateway.do";
            //appId需要申请，在我们上面中有说到申请应用，
            String appId="2016080700185726";
            //企业的密钥
            String privateKey="就是我们上面使用工具生成的密钥";
            //数据传输方式
            String format="json";
            //编码形式
            String charset="utf-8";
            //支付宝公钥
            String alipayPulicKey="配置完成公钥后生成的支付宝公钥";
            //编码方式
            String signType="RSA2";
            //初始化方法
            if(alipayClient==null){
                alipayClient = new DefaultAlipayClient(serverUrl, appId, privateKey, format, charset, alipayPulicKey, signType);
            }
            return alipayClient;
        }
    
    }

配置类是进行初始化支付宝接口的。当我们要进行支付的时候，就先调用类中的success方法得到AlipayClient对象，然后使用他来和支付宝通信 。  
支付具体操作的流程如下  
这个类中使用了手机端html网站支付，pc端html网站支付，还有商家向客户转账的支付三种。可以访问相应的方法来完成支付。

    }

到此支付宝的支付就完成了，如有哪里不好，希望还能大家能补足
