链接适用于所有浏览器，除了 safari(php 代码）

Link works in all browsers except safari (php code)

本文关键字：safari php 代码 除了 适用于 浏览器 链接 | 更新日期: 2023-09-27

>我创建了一个网站，显示特定文件夹（命名文档）的文件和目录。用户可以浏览目录，如果他选择一个文件（pdf文档等），它会下载它。问题是它适用于所有浏览器，但特别是在 safari 中，如果用户选择一个文件（pdf 文档等），它不会下载它，并且会弹出一个新窗口，例如：

请求的网址/root/documents/2013-01-13 1ηΈκÏ"ακÏ"η- 1·Î•Î£/Î ÏακÏ"ικά 1ηÏ' ΕκÏ'"ακÏ'"ηÏ' Î"。Σ.在此服务器上找不到 TÎœ.ΠΛΗΡΟΦΟΠΚΗΣ ΚÎ'ΠΤΗΛΕΠΠΊΟΙ™©™™©™ÎÎ ÎÎ .doc

奇怪的字母应该是希腊语。我试图弄清楚为什么，它只发生在野生动物园中的事实对我来说真的很奇怪。这是负责链接内容的代码。我在负责文件链接的代码上方放了一个大箭头作为注释（它在"if"内）。任何想法都会很有帮助。

您正在从 UTF-8 编码

转换为 UTF-8 编码。结果，野生动物园似乎在不受支持的编码中获取网址，这似乎无法正确处理。

尝试：

if ($encoding !== 'UTF-8'){
        return mb_convert_encoding( $source, 'UTF-8','UTF-8,ISO-8859-7 ');
    }

更新

我做了一些额外的测试，如果将"auto"指定为属性或没有传递第二个属性，似乎mb_detect_encoding()总是返回 UTF-8。我通过如下所示的方式解决了这个问题，但是如果没有实际的文件和路径，则无法完全测试它。试试它是否以这种方式工作：

function convert_to( $source ){
    $encoding = mb_detect_encoding( $source, "Windows-1253,ISO-8859-7,UTF-8" );
    if ($encoding !== 'UTF-8'){
        return mb_convert_encoding( $source, 'utf-8','Windows-1253,ISO-8859-7,UTF-8');
    }
    else {
        return $source;
    }
}
