Twitter API 获取特定用户的最新推文

Question

我需要使用哪个 API 来获取具有公共帐户的特定用户的“n”条最近的推文？

Answer 1

要从特定用户那里获取推文，您需要使用GET statuses/user_timeline API 方法。

Answer 2

自 2013 年 5 月 7 日起，Twitter 已弃用的 v1.0 将停用，v1.1 是访问 API 的唯一方法，通过 OAuth 验证请求.

这意味着您不会完全靠自己使用 PHP 的 file_get_contents() 来获取这类东西 - 您需要编写一个利用 OAuth 和 Twitters v1.1 API 的脚本.

I recently wrote a Stack Overflow answer 帮助新手使用 twitter v1.1 API，我写了一个类来让你更容易。

您需要创建一个开发者帐户，为自己获取一组开发者密钥以在您的应用程序中使用，并使用 OAuth 发出经过身份验证的请求。如果您阅读上面的帖子，您会看到我创建了一个simple class 来允许您执行此操作。

TLDR： 不能再使用 v1.0，为简单起见使用 1.1 和此类：https://github.com/J7mbo/twitter-api-php

Answer 3

带有 PHP 代码的最新 5 条推文。

$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 4

我们可以使用 twitter Rest api 来获取特定用户的推文。可以下载Display Tweets of a particular user in an Android的源码

Answer 5

要获取特定 Twitter 帐户的推文，您可以使用 Twitter API v2 中添加的新 User Tweet Timeline API 方法。
