我试图从网站上找到file_get_contents,但它会输出奇怪的字符,例如 } r H y M n '2I “ ^ÏjI-[D T8w | -Y
<?
echo file_get_contents("http://mp3yum.top");
?>
有没有办法从这个网站上删除一些内容。

} catch (IOException ex){

}

System.out.println("Caught TikaException: " + tx.getMessage());

public static void main(String args[]){
String file = args[0];

DocParser textExtract = new DocParser();
Map<String, Object> extractedMap = textExtract.processRecord(file);
try {

writer.close();
} catch (FileNotFoundException e) {
