Syntaxerror - Syntaxerror: unerwartetes Token <in JSON an Position 1 - Ionic

Wenn ich meine Daten zu meiner Datenbank drücken, bekomme ich ein Problem mit meinem JSON zurück:Syntaxerror - Syntaxerror: unerwartetes Token <in JSON an Position 1 - Ionic

1 
<br/>[email protected]{"userData": {"user_id":"21","name":"eman","email":"[email protected]","username":"username_name","token":"6de6b72ad590562b566675f6f780cb26cf67dc46e73cf025ad5ef7da92735b45"}}

Scheint mich zurück html und nicht JSON Daten, die folgende Fehlermeldung:

SyntaxError: Unexpected token < in JSON at position 1 
    at JSON.parse (<anonymous>)

Hier ist meine API-Code:

postData(credentials, type){ 

    return new Promise((resolve, reject) =>{ 
     let headers = new Headers(); 
     this.http.post(apiUrl+type, JSON.stringify(credentials), {headers: headers}). 
     subscribe(res =>{ 
     resolve(res.json()); 
     }, (err) =>{ 
     reject(err); 
     });

ich den ganzen Tag verbracht zu finden versuchen, eine Lösung, überprüfen Sie jeden Beitrag auf SO aber immer noch keine Lösung finden. Es könnte ein Duplikat sein, aber ehrlich gesagt habe ich die Antwort nicht auf anderen Posts gesehen.

warum diese => '
@ mail.comhere' Mail in ressponse bekommen, überprüft Wetter Ihrer api Antwort Prüfung ist es gültig json zurückkehrt? – Onkar

@Onkar das ist die Antwort, die ich von Json bekomme. Ich weiß nicht, warum ich diese
Mail vor meinem JSON bekomme. Es geht gut in meine Datenbank – ChinaXiaoHong

diese Antwort erstellt Fehler beim Auflösen von Json 'resolve (res.json());', seine Ursache für Fehler – Onkar

Problem ist in SIGNUP() Funktion, zwei mal unerwünschtes Echo gibt es ,

 echo $email_check.'<br/>'.$email;    // remove this unwanted stuff 

     if (strlen(trim($username))>0 && strlen(trim($password))>0 && strlen(trim($email))>0 && $email_check>0 && $username_check>0 && $password_check>0) 
     { 
      echo 'here';   // remove this unwanted stuff 
     ....

echo $email_check.'<br/>'.$email; entfernt diese unerwünschten Dinge

echo 'here'; entfernt diese unerwünschten Dinge

Vielen Dank! Ich weiß nicht, ob das verwandt ist, aber jetzt bekomme ich ein anderes Problem, das ist vendor.js: 1704 FEHLER Fehler: Uncaught (in Versprechen): TypeError: Kann die Eigenschaft 'user_id' von undefined nicht lesen TypeError: Kann Eigenschaft 'user_id' nicht lesen von undefined – ChinaXiaoHong

@ChinaXiaoHier ist das Problem mit dem Typoskript, überprüfen Sie Ihren Code, der nicht mit dieser Frage verbunden ist – Onkar

In Ihrer Anmeldung Funktion müssen Sie diese Zeile entfernen:

echo $email_check.'<br/>'.$email;
