with - API de Twitter para obtener tweets recientes de un usuario en particular

twitter api working with timelines

Question

¿Qué API necesitaría usar para obtener ''n'' tweets recientes de un usuario en particular con una cuenta pública?

Answer 1

A partir del 7 de mayo de 2013 , la v1.0 ya en desuso de Twitter se está retirando y v1.1 es el único método para acceder a la API, utilizando solicitudes autenticadas a través de OAuth .

Esto significa que no podrá utilizar el file_get_contents() PHP por su cuenta para tomar este tipo de cosas: necesita escribir un script que utilice API OAuth y Twitters v1.1.

Hace poco escribí una respuesta de para ayudar a los novatos a la API de Twitter v1.1, y escribí una clase para que esto sea más fácil para usted.

Debe crear una cuenta de desarrollador, obtener un conjunto de claves de desarrollador para usar dentro de su aplicación y realizar solicitudes autenticadas utilizando OAuth. Si lees la publicación anterior, verás que creé una clase simple para permitirte hacer esto.

TLDR: ya no puede usar v1.0, use 1.1 y esta clase para simplificar: https://github.com/J7mbo/twitter-api-php

Answer 2

Para obtener tweets de un usuario específico, querrá usar el método GET status / user_timeline API.

Answer 3

Podemos usar la API api de Rest para obtener los tweets de un usuario en particular. Puede descargar la fuente de Mostrar tweets de un usuario en particular en un Android

Answer 4

los últimos 5 tweets con código PHP.

$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);
