前端：
文档：https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/getPhoneNumber.html

uniapp调用的时候，要将bind用@替换

<button open-type="getPhoneNumber" @getphonenumber="getPhoneNumber"></button>

function getPhoneNumber(e){console.log(e.detail.code)  // 动态令牌console.log(e.detail.errMsg) // 回调信息（成功失败都会返回）console.log(e.detail.errno)  // 错误码（失败时返回）if (e.detail.code){User.getUserTelNumber(e.detail.code).then(res=>{// 授权成功setTimeout(()=>{uni.navigateBack({delta:1 //返回的页面层级，1为返回上一个页面})},1000)}).catch((err)=>{console.log(err,"errrrrrr")})}else{// 拒绝授权toast("拒绝授权","error")setTimeout(()=>{uni.navigateBack({delta:1 //返回的页面层级，1为返回上一个页面})},1000)}}

掉这个获取电话号码，需要先获取access_token
https://developers.weixin.qq.com/miniprogram/dev/OpenApiDoc/mp-access-token/getAccessToken.html
获取token，有效期是两小时，需要缓存，

    @GetMapping("/getTelNumber")@LoginRequired@ApiOperation(value = "getTelNumber",notes = "getTelNumber")public RespBean getTelNumber(String code){userService.getWechatTelNumber(code);return RespBean.ok("授权成功");}

    /*** 获取微信的 accessToken，， 需要缓存起来，，， 两小时过期* @return*/public String getAccessToken(){String tokenUrl = String.format("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s", wechatPayConfig.getAppId(), wechatPayConfig.getAppSecret());Map map = restTemplate.getForObject(tokenUrl, Map.class);String accessToken = (String) map.get("access_token");System.out.println("accessToken = " + accessToken);return accessToken;}

    public void getWechatTelNumber(String code) {try {String accessToken= globalMap.get("access_token");if (accessToken == null){accessToken = getAccessToken();globalMap.put("access_token",accessToken);}//通过token和code来获取用户手机号String url = "https://api.weixin.qq.com/wxa/business/getuserphonenumber?access_token=" + accessToken + "&code=" + code;Map<String, String> map = new HashMap<>();map.put("code",code);Object obj = restTemplate.postForObject(url, map, Object.class);System.out.println("obj = " + obj);Map<String,Object> resultMap = (Map<String,Object>) obj;Map<String,Object> phoneInfo = (Map<String, Object>) resultMap.get("phone_info");System.out.println("phoneInfo = " + phoneInfo);String phoneNumber = (String) phoneInfo.get("phoneNumber");// 将number更新到user表User user = SecurityContextHolder.getUser();user.setTel(phoneNumber);this.updateById(user);} catch (RestClientException e) {throw new ServiceException(e.getMessage());}}
