如何在使用angular2登录前从cookie中获取设备ID

Question

我有一个应用程序，我需要在登录前获取设备ID。所以无论如何都要使用angular获取设备的DeviceId。请帮忙

TS：

login(value: any) {

    let userName = value.email.trim();
    let passWord = value.password.trim();
    let password =  Md5.hashStr(passWord)

    let params = { username: userName, password: password }
    this.authService.doLogin(params)
      .subscribe((data: any) => {

        if(data.Header.Message == "Please check accountId or password"){
          this.msgs = [{ severity: 'error', summary: 'Error Message', detail: 'AccountId Or Password Is Incorrect' }];
        }
        else if(data.Header.Message == "Account is already deleted"){
          this.msgs = [{ severity: 'error', summary: 'Error Message', detail: 'This user account is deleted from medicamind' }];

        }
        else if(Cookie.get("DeviceUID") != null){
          alert("hi")
          console.log(Cookie.get("DeviceUID"));
          this.msgs = [{ severity: 'error', summary: 'Error Message', detail: 'This is not registered device, please login with sms/email authentication' }];
         }
        else if (data.Body.Data.token && data.Body.Data.id != -2) {
          localStorage.setItem("userId_ls",data.Body.Data.userID)
          localStorage.setItem('accountId_ls',data.Body.Data.accountID)

          this.router.navigate(['/home']);
        }
        else {
        }
      })
