需求:
用户点击公众号菜单跳转到自定义带引流码的链接

网页授权 | 微信开放文档
大致流程:
1.在公众号菜单配置链接:
https://open./connect/oauth2/authorize?appid=XXXXXXXXXXXX&redirect_uri=https%3A%2F%2F测试域名%2Fws_dabai%2Fweixin%2Fcallback%2FredirectInsurePage&response_type=code&scope=snsapi_userinfo&state=XXXXXXXXXXXXhttps://open./connect/oauth2/authorize?appid=XXXXXXXXXXXX&redirect_uri=https%3A%2F%2Fopen.anyitech.ltd%2Fws_dabai%2Fweixin%2Fcallback%2FredirectInsurePage&response_type=code&scope=snsapi_userinfo&state=wx689e5802c3e14e5c#wechat_redirect
上面浅蓝色部分需替换为当前公众号id,和测试环境对应的域名,测试域名https开头.
2.点击菜单用户会请求到后台服务: 根据返回的code 获取当前用户的openId, 然后根据openId查询引流人员编码 marketingCode, 最后根据 marketingCode查询对应推广员的链接
/*** @Title: 公众号回调 Controller* @Author: ken* @Description:* @Date: /7/26 18:14**/@Api(value = "获取微信openId总入口", tags = "获取微信openId总入口")@Slf4j@RestController@RequestMapping("/callback")public class WechatCallController {@Autowiredprivate MarketingService marketingService;@ApiOperation("微信回调获取openId并跳转投保H5链接")@GetMapping(value = "/redirectInsurePage")public void redirectInsurePage(@RequestParam String code, @RequestParam String state, HttpServletResponse response) {log.info("WechatPageController--> redirectInsurePage--> code：{}, state：{}", code, state);String url = marketingService.getUrl(code, state);log.info("WechatPageController--> redirectInsurePage--> url：{}", url);//重定向页面到投保连接页面(url 需要解码)String urlEncoder = "";try {urlEncoder = URLEncoder.encode(url, StandardCharsets.UTF_8.toString());log.info("WechatPageController--> redirectInsurePage--> urlEncoder：{}", urlEncoder);} catch (UnsupportedEncodingException e) {log.error("WechatPageController --> redirectInsurePage URLEncoder.encode error：{}", e.getMessage(), e);}try {response.sendRedirect(url);} catch (IOException e) {log.error("WechatPageController --> redirectInsurePage response.sendRedirect error：{}", e.getMessage(), e);}/*RedirectView redirectView = new RedirectView();// 设置重定向的URLredirectView.setUrl(urlEncoder);return redirectView;*/}}
实现类:
@Overridepublic String getUrl(String code, String appId) {//获取用户openIdCommonWechatByCodeReq commonWechatByCodeReq = new CommonWechatByCodeReq(code, appId);CommonWechatInfoByCode commonWechatInfoByCode = cbsWechatRemoteService.getAccessToken(commonWechatByCodeReq);log.info("MarketingServiceImpl-->getUrl--> cbsWechatRemoteService.getAccessToken ：{}",JSONObject.toJSONString(commonWechatInfoByCode));String openId = commonWechatInfoByCode.getOpenid();//调用2b2a 根据open获取第一次绑定的 marketingCodeString marketingCode = "";try {marketingCode = tbTaRemoteService.getMarketingCode(appId, openId);} catch (Exception e) {log.error("MarketingServiceImpl --> getUrl tbTaRemoteService.getMarketingCode error：{}", e.getMessage(), e);}log.info("MarketingServiceImpl --> getUrl tbTaRemoteService.getMarketingCode--> marketingCode ：{}", marketingCode);if(Objects.isNull(marketingCode) || StringUtils.isEmpty(marketingCode)){return DEFAULT_URL;}//根据 marketingCode 查询推广员对应的投保链接QueryWrapper<MarketingExt> wrapper = new QueryWrapper<>();wrapper.eq("marketing_code", marketingCode);List<MarketingExt> marketingExtList = marketingExtMapper.selectList(wrapper);if (CollectionUtils.isEmpty(marketingExtList)) {return DEFAULT_URL;}return marketingExtList.get(0).getUrl();}}
3.通过重定向跳转到查询到的推广链接页面.
注意:这里返回的链接不能再编码
