Twitter API, um aktuelle Tweets eines bestimmten Benutzers zu erhalten

Question

Welche API müsste ich verwenden, um die letzten Tweets eines bestimmten Benutzers mit einem öffentlichen Konto zu erhalten?

Answer 1

Um Tweets von einem bestimmten Benutzer zu erhalten, möchten Sie die GET statuses/user_timeline API-Methode verwenden.

Answer 2

neuesten 5 Tweets mit PHP-Code.

$tweets_result=file_get_contents("https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=username&count=5"); 
$data=json_decode($tweets_result); 
print_r($data); 

Answer 3

Ab 7. Mai 2013 wird Twitters bereits veraltet v1.0 im Ruhestand ist und v1.1 ist die einzige Methode der Zugriff auf das API, authentifizierte Anforderungen über OAuth verwenden.

Das heißt, Sie nicht der Lage sein, PHP zu verwenden file_get_contents() ganz auf seine eigene diese Art der Sache zu packen - Sie benötigen ein Skript zu schreiben, die OAuth und Twitters v1.1 API verwendet.

I recently wrote a Stack Overflow answer, um Neulingen an der twitter v1.1 API zu helfen, und ich schrieb eine Klasse, um Ihnen dies zu erleichtern.

Sie müssen ein Entwicklerkonto erstellen, sich eine Reihe von Entwicklerschlüsseln zur Verwendung in Ihrer Anwendung besorgen und authentifizierte Anforderungen mithilfe von OAuth erstellen. Wenn Sie den obigen Beitrag lesen, sehen Sie, dass ich eine simple class erstellt habe, um Ihnen dies zu ermöglichen.

TLDR: Kann nicht v1.0 nicht mehr verwenden möchten, verwenden 1.1 und diese Klasse der Einfachheit halber: https://github.com/J7mbo/twitter-api-php

Wir können die twitter Ruhe api verwenden, um die Tweets von bestimmten Benutzer zu erhalten. Sie können
