我正在建立一个股票分析网站来使用股票信息,例如价格历史等。一旦我获得数据,我将实施一些我自己的算法,但我在获取历史数据时遇到了麻烦。该网站托管在免费的网络托管上biz.nf. 包含的 connect.php 文件包含所有需要的 sql 信息并连接到数据库。我在那里进行了错误检查,所以我知道那不是问题所在。我还尝试手动复制/粘贴链接,它们可以正常工作,因此我正在正确创建 URL。我在这个网站和其他网站上遇到了一些类似的主题,但我没有看到如何解决它的明确解决方案或它发生的明确原因。雅虎是不是屏蔽了我?还,我想提一下,我对 php 编程很陌生,但我在 C 和 C++ 方面有很深的背景,所以如果可以的话,请在提供任何帮助时考虑这一点。提前致谢!
这是我执行的 index.php 文件的代码

这是我得到的错误:
[function.file-get-contents]: failed to open stream: Connection refused in /srv/disk12/1368341/www/nemanja.co.nf/index.php on line 26
我在发生错误的地方以粗体显示文本(每边 2 个星号)。
此外,托管该网站的服务器具有 allow_url_fopen = 1 如果是这种情况 yahoo.com 阻止了我,有没有办法解决这个问题?是否有另一种获取所有历史股票数据的方法?
