<div class =“post-text”itemprop =“text”>
  <P>
    你需要在这里实现Observable调用，
  </p>
   <pre>
    <code>
      import { Subscription } from "rxjs";

...

referralSubscription: Subscription;

...

createReferralUrls() {
    this.referralSubscription = this.referralService.generateReferralUrl(this.userData.referralId)
    .subscribe(
     (res)=>{        
        this.campaignMessage = 'Sign up here: ' + res + '.';
        this.facebookShareUrl = 'http://www.facebook.com/sharer/sharer.php?u=' + res;
        this.whatsappShareUrl = 'https://wa.me/?text=' + this.campaignMessage;
        this.twitterShareUrl = 'https://twitter.com/intent/tweet?text=' + this.campaignMessage;
        this.emailShareUrl = 'mailto:?subject=Welcome to our site!&body=' + this.campaignMessage;        
    }
   );      
  }

</code>
  </pre>
  <P>
    请同时添加您的服务，以便我们也可以编辑您的服务返回类型。

    </强>
    
如下更改您的服务，
  </p>
   <pre>
    <code>
        generateReferralUrl(referralId) {
    if (location.host === 'localhost:4200') {
      return Observable.create((observer) => { observer.next('localhost:4200/invite/' + referralId) });
    } else if (location.host === 'myapp.herokuapp.com') {
      return Observable.create((observer) => { observer.next('myapp.herokuapp.com/invite/' + referralId) });
    } else if (location.host === 'myapp.com') {
      return Observable.create((observer) => { observer.next('myapp.com/invite/' + referralId) });
    }
  }

</code>
  </pre>
</DIV>
