Wie kann ich Extrahieren Sie nur das Schlüsselwertpaar "followers_count". Da dies der einzige Teil ist, den ich brauche. Ich kann andere nachher wählen, aber das ist der Hauptteil. Ich habe versucht, etwas zu tun, wie:

console.log(response.body['followers_count']); 

Aber das funktioniert nicht.

Answer 1

Kurze Antwort ist:

var responseObject = JSON.parse(response); 
console.log(responseObject[0].followers_count) 

Wohlgemerkt, die Zeichenfolge, die Sie oben klebte als Antwort kein gültiger JSON, aber ich nehme an, es ist ein errore in copy/paste. Sie können eine online json validator verwenden, um es zu testen.

Answer 2

response[0].followers_count; das wird funktionieren.
