开发接口文章来源地址https://www.toymoban.com/news/detail-509930.html
1.添加依赖
<!-- 支付宝核心sdk -->
<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>4.22.113.ALL</version>
</dependency>
<!-- 加解密钥sdk -->
<dependency>
<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>
<version>1.62</version>
</dependency>
2.配置信息
package com.ruoyi.common.utils.alipay;
public class AlipayConfig {
/**
* 支付宝AppId
*/
public static final String APP_ID = "";
// 商户id
public static String SELLERID = "";
// 应用私钥 pkcs8格式的
public static String RSA_PRIVATE_KEY = "";
// 支付宝公钥
public static String ALIPAY_PUBLIC_KEY = "";
// 请求网关地址
public static String URL = "https://openapi.alipay.com/gateway.do";
// 编码
public static String CHARSET = "UTF-8";
// 返回格式
public static String FORMAT = "json";
// 日志记录目录
public static String log_path = "/log";
// RSA2
public static String SIGNTYPE = "RSA2";
}
3.工具类AlipayUtils
package com.ruoyi.common.utils.alipay;
import com.alipay.api.AlipayApiException;
import com.alipay.api.CertAlipayRequest;
import com.alipay.api.DefaultAlipayClient;
import com.alipay.api.domain.AlipayOpenAppQrcodeCreateModel;
import com.alipay.api.request.AlipayOpenAppQrcodeCreateRequest;
import com.alipay.api.request.AlipaySystemOauthTokenRequest;
import com.alipay.api.request.AlipayUserInfoShareRequest;
import com.alipay.api.response.AlipayOpenAppQrcodeCreateResponse;
import com.alipay.api.response.AlipaySystemOauthTokenResponse;
import com.alipay.api.response.AlipayUserInfoShareResponse;
public class AlipayUtils {
/**
* 服务端获取access_token、user_id
*
* @param authCode
* @return
* @throws Exception
*/
public static AlipaySystemOauthTokenResponse getAccessToken(String authCode) throws Exception {
CertAlipayRequest certAlipayRequest = new CertAlipayRequest();
// 实例化客户端（参数：网关地址、商户appid、商户私钥、格式、编码、支付宝公钥、加密类型）
certAlipayRequest.setServerUrl(AlipayConfig.URL);
certAlipayRequest.setAppId(AlipayConfig.APP_ID);
certAlipayRequest.setPrivateKey(AlipayConfig.RSA_PRIVATE_KEY);
certAlipayRequest.setFormat(AlipayConfig.FORMAT); // JSON
certAlipayRequest.setCharset(AlipayConfig.CHARSET); // UTF-8
certAlipayRequest.setSignType(AlipayConfig.SIGNTYPE); // RSA2
// 上传csr文件后 完成配置,支付宝后台能下载3个文件
// 应用公匙/home/ruoyi
certAlipayRequest.setCertPath("");
// 支付宝公匙
certAlipayRequest.setAlipayPublicCertPath("/home/ruoyi/xmcrt/alipayCertPublicKey_RSA2.crt");
// 支付宝 根 公匙
certAlipayRequest.setRootCertPath("/home/ruoyi/xmcrt/alipayRootCert.crt");
DefaultAlipayClient alipayClient = new DefaultAlipayClient(certAlipayRequest);
// 实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.system.oauth.token
AlipaySystemOauthTokenRequest request = new AlipaySystemOauthTokenRequest();
request.setGrantType("authorization_code");
request.setCode(authCode);
AlipaySystemOauthTokenResponse response = alipayClient.certificateExecute(request);
if (response.isSuccess()) {
System.out.println("调用成功");
} else {
System.out.println("调用失败");
}
return response;
}
/**
* 生成支付宝小程序二维码
*
* @param urlParam 小程序中能访问到的页面路径
* @param queryParam 小程序的启动参数，打开小程序的query ，在小程序 onLaunch的方法中获取
* @param describe 对应的二维码描述
* @return
*/
public static String createQrCode(String urlParam, String queryParam, String describe) {
String qrCodeUrl = "";
try {
CertAlipayRequest certAlipayRequest = new CertAlipayRequest();
// 实例化客户端（参数：网关地址、商户appid、商户私钥、格式、编码、支付宝公钥、加密类型），为了取得预付订单信息
certAlipayRequest.setServerUrl(AlipayConfig.URL);
certAlipayRequest.setAppId(AlipayConfig.APP_ID);
certAlipayRequest.setPrivateKey(AlipayConfig.RSA_PRIVATE_KEY);
certAlipayRequest.setFormat(AlipayConfig.FORMAT);
certAlipayRequest.setCharset(AlipayConfig.CHARSET);
certAlipayRequest.setSignType(AlipayConfig.SIGNTYPE);
// 上传csr文件后 完成配置,支付宝后台能下载3个文件
// 应用公匙/home/ruoyi
certAlipayRequest.setCertPath("");
// 支付宝公匙
certAlipayRequest.setAlipayPublicCertPath("/home/ruoyi/xmcrt/alipayCertPublicKey_RSA2.crt");
// 支付宝 根 公匙
certAlipayRequest.setRootCertPath("/home/ruoyi/xmcrt/alipayRootCert.crt");
DefaultAlipayClient alipayClient = new DefaultAlipayClient(certAlipayRequest);
// 实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.open.app.qrcode.create
AlipayOpenAppQrcodeCreateRequest request = new AlipayOpenAppQrcodeCreateRequest();
// SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式
AlipayOpenAppQrcodeCreateModel model = new AlipayOpenAppQrcodeCreateModel();
model.setUrlParam(urlParam);
model.setQueryParam(queryParam);
model.setDescribe(describe);
request.setBizModel(model);
AlipayOpenAppQrcodeCreateResponse response = alipayClient.certificateExecute(request);
System.out.println(response.getQrCodeUrl());
qrCodeUrl = response.getQrCodeUrl();
} catch (AlipayApiException e) {
e.printStackTrace();
}
return qrCodeUrl;
}
}
4.controller层接口
@PostMapping("/authLogin")
@ResponseBody
public AjaxResult authLogin(@RequestParam String authCode, @RequestParam String nickName,
@RequestParam String avatar) {
logger.info("-----------授权登录 authCode[{}], nickName[{}], avatar[{}], parentId[{}]", authCode, nickName, avatar,
parentId);
try {
// 1. 服务端获取access_token、user_id
AlipaySystemOauthTokenResponse response = AlipayUtils.getAccessToken(authCode);
if (response.isSuccess()) {
// 获取用户信息
String accessToken = response.getAccessToken();
String alipayUserId = response.getUserId();
logger.info("-----------accessToken:" + accessToken);
logger.info("-----------alipayUserId:" + alipayUserId);
XmUser xmUser = iXmUserService.getByAlipayUserId(alipayUserId);
if (xmUser != null) {
return AjaxResult.success(xmUser);
} else {
XmUser newXmUser = new XmUser();
newXmUser.setAlipayUserId(alipayUserId);
newXmUser.setNickName(nickName);
newXmUser.setAvatar(avatar);
iXmUserService.insertXmUser(newXmUser);
// 生成用户id二维码
String qrCodeUrl = AlipayUtils.createQrCode("pages/index/index",newXmUser.getId(), "二维码");
XmUser newXmUser2 = new XmUser();
newXmUser2.setId(newXmUser.getId());
newXmUser2.setQrCode(qrCodeUrl);
iXmUserService.updateXmUser(newXmUser2);
return AjaxResult.success(iXmUserService.getByAlipayUserId(alipayUserId));
}
}
return AjaxResult.error("获取access_token - 调用失败！");
} catch (Exception e) {
e.printStackTrace();
return AjaxResult.error("授权登录异常");
}
}
