本人开发负责微信公众号端,菜单都是自定义菜单,然后每个菜单路径都是经过授权如:http://xxxx.com/ceshi/wechat/authorize?returnUrl=http://xxxx.com/charge/#/setParameters
经过后台授权后返回给前端页面拼接当前用户的openid
http://xxxx.com/charge/#/setParameters?openid=xxxxxxxx
这样进行注册,登录都可以传递openid让前端可以获取openid来关联微信账户信息.
理想状态是这样的,然而实验后发现,.微信授权返回的returnurl,会把路径截取成http://xxxx.com/charge/这样的重定向后,前端那边处理直接跳转到登录接口了,然后看了很多的解决方案,有跳转空白页面,来location.href真正的路径的.这边我的解决方案就是自定义菜单路径是先忽略掉#,比如之前的
http://xxxx.com/ceshi/wechat/authorize?returnUrl=http://xxxx.com/charge/#/setParameters
改正后returnUrl=http://xxxx.com/charge/setParameters
然后后台这边再把路径进行重新拼接#号,以下为代码片段帮助理解.

    WxMenuButton button1 = new WxMenuButton();
    button1.setName("充值");
    WxMenuButton button11 = new WxMenuButton();
    button11.setType(MenuButtonType.VIEW);
    button11.setName("充值");
    button11.setUrl("http://xxxx.com/ceshi/wechat/authorize?returnUrl=http://xxxx.com/charge/home");

    WxMenuButton button12 = new WxMenuButton();
    button12.setType(MenuButtonType.VIEW);
    button12.setName("充值历史记录");
    button12.setUrl("http://xxxx.com/ceshi/wechat/authorize?returnUrl=http://xxxx.com/charge/operationRecord");

  @RequestMapping(value = "authorize",method = RequestMethod.GET)
    public String authorize(@RequestParam("returnUrl") String returnUrl) throws Exception{
        String url=config.getRealmName()+"/ceshi/wechat/userInfo";
        String redirectUrl=wxMpService.oauth2buildAuthorizationUrl(url,WxConsts.OAuth2Scope.SNSAPI_USERINFO, URLEncoder.encode(returnUrl,
                "UTF-8"));
        logger.info("【微信网页授权】获取code,redirectUrl={}",redirectUrl);
        return "redirect:"+redirectUrl;//重定向到下面一个方法
    }
    @RequestMapping(value = "userInfo",method = RequestMethod.GET)
    public String userInfo(@RequestParam("code") String code,
                         @RequestParam("state") String returnUrl){
        WxMpOAuth2AccessToken wxMpOAuth2AccessToken=new WxMpOAuth2AccessToken();
        try {
            wxMpOAuth2AccessToken=wxMpService.oauth2getAccessToken(code);
        }catch (WxErrorException e){
            logger.error("【微信网页授权】,{}",e);
        }
        String openId=wxMpOAuth2AccessToken.getOpenId();
        logger.info("【微信网页授权】获取openid,returnUrl={}",returnUrl);
        try {

                WxMpUser wxMpUser = wxMpService.oauth2getUserInfo(wxMpOAuth2AccessToken, null);
               //TODO 保存授权用户信息
        } catch (WxErrorException e) {
            logger.info("【微信网页授权】获取用户信息异常={}",e.getError());
        }
        String[] split = returnUrl.split("/charge/");
        String url = "http://xxxx.com/charge/#/"+split[1];
        return "redirect:"+ url+"?openid="+openId;
    }
