Angular 数据库错误消息中未找到电子邮件

大家好，我需要你们的帮助。我有一个密码重置表单，如果电子邮件是数据库中带有“成功警报消息”的已注册电子邮件，则会向用户电子邮件发送重置链接，但我注意到未注册的电子邮件仍然显示成功警报消息，而不是错误消息（“未找到用户”）。但当我在邮递员上测试它时，如果电子邮件已注册，它会显示成功警报，如果未注册，它会显示错误警报。我不知道哪里弄错了，下面是我的代码。谢谢

放弃密码。ts

async forgetPassword(){
   if(this.usernameEmail !==''){

    this.auth.resetPassword(this.usernameEmail).then( (res) =>{

      this.CFS.presentToast('Password reset link has been sent to your registered email. ', 'buttom',3000, 'success');

      this.route.navigate(['/login']);
    },
   (err) => {
      this.CFS.presentToast('Reset password fail, User not found', 'buttom',3000, 'danger');
      console.log(err)
    });
   } else{
    this.CFS.presentToast('Email address is required ', 'buttom',2000, 'danger');
   }

  }

resetPassword(usernameEmail){

  let headers = new HttpHeaders ({
    'Content-Type': 'application/x-www-form-urlencoded'
  });

  this.apiUrl = `${this.siteUrl}/api/forget_password.php?login=${usernameEmail}`;
  console.log('API URL for register a customer: ', this.apiUrl);

  return new Promise ((resolve) => {
    this.http.post(this.apiUrl, {headers}).subscribe((successResp) => {
        resolve(successResp);

    },
    error => {
      resolve(error);  
      console.log('email not found',error) 
    })
  });
}

authservice.ts

async forgetPassword(){
   if(this.usernameEmail !==''){

    this.auth.resetPassword(this.usernameEmail).then( (res) =>{

      this.CFS.presentToast('Password reset link has been sent to your registered email. ', 'buttom',3000, 'success');

      this.route.navigate(['/login']);
    },
   (err) => {
      this.CFS.presentToast('Reset password fail, User not found', 'buttom',3000, 'danger');
      console.log(err)
    });
   } else{
    this.CFS.presentToast('Email address is required ', 'buttom',2000, 'danger');
   }

  }

resetPassword(usernameEmail){

  let headers = new HttpHeaders ({
    'Content-Type': 'application/x-www-form-urlencoded'
  });

  this.apiUrl = `${this.siteUrl}/api/forget_password.php?login=${usernameEmail}`;
  console.log('API URL for register a customer: ', this.apiUrl);

  return new Promise ((resolve) => {
    this.http.post(this.apiUrl, {headers}).subscribe((successResp) => {
        resolve(successResp);

    },
    error => {
      resolve(error);  
      console.log('email not found',error) 
    })
  });
}

你能提供stackblitz吗？试试控制台在forgetPassword的第一行记录这个.username电子邮件吗？你能在控制台上记录吗。记录（成功响应）并共享相关信息？获取始终相同的结果意味着您始终输入subscribe。然后，您可以在订阅中发送成功和不成功结果检查失败响应的状态代码，它不应为200。然后，只有它会进入您的错误块并打印所需的内容。基本上检查您从后端收到的响应的状态代码。这是我的控制台中包含的消息“HttpErrorResponse{headers:HttpHeaders，status:0，statusText:“未知错误”，url:，ok:false，…}”，适用于已注册电子邮件或未注册电子邮件。对于已注册的电子邮件，我收到了一个重置链接
