PHP中的RSS阅读器

 header('Access-Control-Allow-Origin: *');
 $tmpFile = 'tmpFile.txt';

 $val="http://rss.news.yahoo.com/rss/topstories";
  $curlHandle = curl_init($val);  
 $filePointer = fopen($tmpFile, "w");  
 curl_setopt($curlHandle, CURLOPT_FILE, $filePointer);  
 curl_exec($curlHandle);
 curl_close($curlHandle);
 fclose($filePointer); 

 $linesArr = file($tmpFile);  
 foreach($linesArr as $eachLine){
 echo($eachLine);
}

程序应该从Yahoo RSS站点获取所有材料，并将它们输出到tmpFile中。

执行程序后，我打开了tmpFile.txt。它显示

c1.ops.sp1.yahoo.com未压缩/分块星期三Apr 11 01：46：41 UTC 2012-->

这看起来不太对劲。我粘贴了urlhttp://rss.news.yahoo.com/rss/topstories有很多资料返回。

解决方案

您需要的是curl_setopt($curlHandle, CURLOPT_ENCODING , "gzip");.yahoo将compression用于其rss源.

其他信息包括。

A.CURLOPT_USERAGENT.如果您不这样做，就不会开始看起来像垃圾邮件，这很好

B.CURLOPT_TIMEOUT.只是为了提高效率

C.CURLOPT_FOLLOWLOCATION..由于干净的URL和路由问题

工作代码

header ( 'Access-Control-Allow-Origin: *' );
$tmpFile = 'out.txt';

$val = "http://rss.news.yahoo.com/rss/topstories";
$curlHandle = curl_init ( $val );
$filePointer = fopen ( $tmpFile, "w" );
curl_setopt ( $curlHandle, CURLOPT_FILE, $filePointer );
curl_setopt($curlHandle, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/533.2 (KHTML, like Gecko) Chrome/5.0.342.3 Safari/533.2');
curl_setopt($curlHandle, CURLOPT_ENCODING , "gzip");
curl_setopt($curlHandle, CURLOPT_TIMEOUT,5);
curl_setopt($curlHandle, CURLOPT_FOLLOWLOCATION, TRUE);
curl_exec ( $curlHandle );
curl_close ( $curlHandle );
fclose ( $filePointer );

$linesArr = file ( $tmpFile );
foreach ( $linesArr as $eachLine ) {
    echo ($eachLine);
}
