我正在尝试使用php进行Datumbox Twitter情绪分析，为此我使用了这里的代码
http://blog.datumbox.com/how-to-build-your-own-twitter-sentiment-analysis-tool/
但它显示了这样的错误，甚至我在config.php 中填写了密钥
Fatal error: Uncaught exception 'TwitterApiException' with message 'Operation timed out after 5015 milliseconds with 0 bytes received' in C:'xampp'htdocs'test'twitter'lib'twitter-client.php:423 Stack trace: #0 C:'xampp'htdocs'test'twitter'lib'twitter-client.php(349): TwitterApiClient::http_request('https://api.twi...', Array) #1 C:'xampp'htdocs'test'twitter'lib'twitter-client.php(239): TwitterApiClient->rest_request('search/tweets', Array, 'GET') #2 C:'xampp'htdocs'test'twitter'lib'TwitterSentimentAnalysis.php(56): TwitterApiClient->call('search/tweets', Array, 'GET') #3 C:'xampp'htdocs'test'twitter'lib'TwitterSentimentAnalysis.php(40): TwitterSentimentAnalysis->getTweets(Array) #4 C:'xampp'htdocs'test'twitter'index.php(31): TwitterSentimentAnalysis->sentimentAnalysis(Array) #5 {main} thrown in C:'xampp'htdocs'test'twitter'lib'twitter-client.php on line 423
我这边或者代码有问题吗？
在我看来，Twitter API客户端无法访问证书。请确保它位于正确的位置，并且具有读取权限。
