有没有办法将起始链接添加到未知的m3u8文件

Question

我最近写了一个代码，它使用file_get_contents以及一些USER_AGENT头和其他头来获取m3u8文件的源代码，当回显时，它看起来如下所示

#EXTM3U #EXT-X-STREAM-INF:CLOSED-CAPTIONS=NONE,RESOLUTION=1280x720,FRAME-RATE=25.000,CODECS="avc1.4d001f,mp4a.40.2",AVERAGE-BANDWIDTH=1500000,BANDWIDTH=1870000 tracks-v1a1/mono.m3u8?token=XYZ_YIE2kpAL6yriswpbrwGAvA%3D%3D%2C1608554743.5691007667

现在我写了一段代码，将曲目添加到url ( http://example.com/mono.php? -v1a1one)。

$test_value = str_replace('tracks-v1a1/mono.m3u8?token=' . "(*^\)", "http://example.com/mono.php/tracks-v1a1/mono.m3u8?token=" . "-1/", $hs2);

我也试过使用preg_replace，但是没有成功，有没有人能找出我的错误。

根据第四只鸟先生的链接和代码编辑，下面的代码工作起来很有魅力

<?php

$hs2 = '#EXTM3U #EXT-X-STREAM-INF:CLOSED-CAPTIONS=NONE,RESOLUTION=1280x720,FRAME-RATE=25.000,CODECS="avc1.4d001f,mp4a.40.2",AVERAGE-BANDWIDTH=1500000,BANDWIDTH=1870000 tracks-v1a1/mono.m3u8?token=XYZ_YIE2kpAL6yriswpbrwGAvA%3D%3D%2C1608554743.5691007667';
$pattern = "~tracks-v1a1/mono\.m3u8\?token=\S+~";
$replacement = "http://example.com/mono.php?$0";
$test_value = preg_replace($pattern, $replacement, $hs2);

echo $test_value;

非常感谢“第四只鸟”先生

你可以使用

$hs2 = '#EXTM3U #EXT-X-STREAM-INF:CLOSED-CAPTIONS=NONE,RESOLUTION=1280x720,FRAME-RATE=25.000,CODECS="avc1.4d001f,mp4a.40.2",AVERAGE-BANDWIDTH=1500000,BANDWIDTH=1870000 tracks-v1a1/mono.m3u8?token=XYZ_YIE2kpAL6yriswpbrwGAvA%3D%3D%2C1608554743.5691007667';
$pattern = "~tracks-v1a1/mono\.m3u8\?token=\S+~";
$replacement = "http://example.com/mono.php?$0";
$test_value = preg_replace($pattern, $replacement, $hs2);

echo $test_value;

输出

#EXTM3U #EXT-X-STREAM-INF:CLOSED-CAPTIONS=NONE,RESOLUTION=1280x720,FRAME-RATE=25.000,CODECS="avc1.4d001f,mp4a.40.2",AVERAGE-BANDWIDTH=1500000,BANDWIDTH=1870000 http://example.com/mono.php?tracks-v1a1/mono.m3u8?token=XYZ_YIE2kpAL6yriswpbrwGAvA%3D%3D%2C1608554743.5691007667
