Ionic2 / Angular2 MailChimp API GET response

问题

Okey so I've got a little problem with MailChimp response. So here is the thing.

I want to check the status of the subscribed user. I have the PHP code which is works fine and i have the code which is also works fine so I get the response BUT I can't use the response after it. So here is the codes:

I have a MailService provider which contain this function:

postCheck(post: {email: string}): Observable<any>{
    const email = JSON.stringify(post);
    let headers = new Headers();
    headers.append('Content-Type', 'application/x-www-urlencoded');
    return this.http.post('http://localhost:8100/getapi', email, {
      headers: headers
    }).map(res => {
          console.log(res.json())
          return res.json(); //add this line
       });
  }

In the main page I have this function:

sendCheck(email: string){
      this.mailservice.postCheck({email: email})
      .subscribe(
        response => this.response = response.status,
        error => console.log(error)
      );
  }

In the main page html when i call <p>{{ response }}</p> it write out 'pending' or 'subscribed'. But after it when I try console.log(this.response); it write out nothing so in the code I can't really do the checking.

From what I can gather, you want to do something with your response after the data has arrived. This you need to do inside the subscription, to ensure that the data is available. So something like this:

sendCheck(email: string){
  this.mailservice.postCheck({email: email})
  .subscribe(response => { 
     this.response = response.status;
     // here the value has been set to response, so do what you want
     this.doSomethingWithResponse();
  )};
}

doSomethingWithResponse() {
  if(this.response == 'subscribed') {
     // do stuff
  }
}
