本文介绍如果通过微信小程序的getPhoneNumber方法获取用户微信绑定的手机号并自动注册登录。
1、前端获取手机号
<template><nut-button size="large" block color="#1890FF" :loading="loading" openType="getPhoneNumber" @getphonenumber="wxLogin">微信一键登录</nut-button></template>
1、按钮类型 openType 指定 "getPhoneNumber"
2、@getphonenumber必须全部小写
// 微信一键登录事件async function wxLogin(e) { loading.value = true;try {const result = await wxNumberLogin({appid: getAppId(), // 微信小程序APPIDcode: e?.detail?.code,openId: openId.value, // 微信小程序openID });if (isRespondSuccess(result)){const from_url = Taro.getCurrentInstance().router?.params["from_url"];if (from_url && (from_url !== 'undefined')){Taro.reLaunch({url: from_url});} else {Taro.switchTab({url: `${ROUTER_ENUM.PAGE_HOME}`});}}} finally {loading.value = false;}}
code：手机号获取凭证：动态令牌。可通过动态令牌换取用户手机号。
2、后台自动注册账号
后台根据前端传入的code获取手机号并自动将手机号注册为账号。
public CommonResult<UserToken> getPhoneNumberRegister(String code, String appid, RegisterParams params) {String urlGetPhoneNumber = WxPlatformConstants.CODE_GET_PHONENUMBER.replaceFirst("ACCESS_TOKEN", getAuthAccessToken(appid));Map<String, String> map = new HashMap<>();map.put("code", code);String result = HttpUtil.doPostUseJsonParams(urlGetPhoneNumber, map, HttpCharset.UTF8);log.info("getPhoneNumber_result:" + result);JSONObject object = JSON.parseObject(result);JSONObject phoneObject = object.getJSONObject("phone_info");String phone = phoneObject.getString("phoneNumber");params.setMobile(phone);return sysUserService.register(params, false); // 不需要校验验证码}
1、 常量参数CODE_GET_PHONENUMBER ：
CODE_GET_PHONENUMBER = "https://api./wxa/business/getuserphonenumber?access_token=ACCESS_TOKEN";
2、微信返回的参数：
{"errcode":0,"errmsg":"ok","phone_info": {"phoneNumber":"xxxxxx","purePhoneNumber": "xxxxxx","countryCode": 86,"watermark": {"timestamp": 1637744274,"appid": "xxxx"}}}
