基于thinkjs2.2的用户登录验证，中途传不了数据return this.model('user').checkUsername(username, phone);

有新的手机号注册，但是执行到console.log(‘a’)就不执行return this.model(‘user’).checkUsername(username, phone);小弟实在不懂 getUserByPhone (phone) { return this.model(‘users’).where({phone: phone}).find(); }; checkUsername (username, phone) { return this.model(‘users’).where({username: username, phone: [’!=’, phone]}).count(‘username’); };

if (isEmpty(errMsg)) {
          return this.model('user').getUserByPhone(phone).then(function (data) {
            if (!isEmpty(data) && data.status > 0) {
              return Promise.reject({
                code: -1,
                info: '手机号已被注册',
                data: {}
              });
            }else{
              **console.log('a');**
              return this.model('user').checkUsername(username, phone);
            }
          }).then(function (data) {
             console.log('b');
              if (data <= 0) {
                return this.model('user').ckeckVerificationOnReg(phone);
              } else {
                return Promise.reject({
