Question

我正在尝试使用一个类使用twitter api v1.1进行一些搜索，但每次我得到并且身份验证错误消息：

这是我正在使用的代码：

尝试使用 Twitter API 1.1 Client for WordPress 。

实施起来非常简单，您只需要 consumer_key 和 consumer_secret 。

示例（来自README）：

<?php

// Include Twitter API Client
require_once( 'class-wp-twitter-api.php' );

// Set your personal data retrieved at https://dev.twitter.com/apps
$credentials = array(
  'consumer_key' => 'xxxxxxxxxxxxxxxx',
  'consumer_secret' => 'xxxxxxxxxxxxxxxx'
);

// Let's instantiate Wp_Twitter_Api with your credentials
$twitter_api = new Wp_Twitter_Api( $credentials );

// Example a - Retrieve last 5 tweets from my timeline (default type statuses/user_timeline)
$query = 'count=5&include_entities=true&include_rts=true&screen_name=micc1983';
var_dump( $twitter_api->query( $query ) );
