【问题】
写了几行PHP代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | /** * add newline for print */function printAutoNewline($contentToPrint) { print_r($contentToPrint."<br />");}/** * get url reponse html */function getUrlRespHtml($url) { printAutoNewline("input url=".$url); $respHtml = ""; //resource fsockopen ( string $hostname [, int $port = -1 [, int &$errno [, string &$errstr [, float $timeout = ini_get("default_socket_timeout") ]]]] ) $res = fsockopen($url); printAutoNewline($res); return $respHtml;}$yesllRespHtml = getUrlRespHtml($yellEntryUrl);printAutoNewline("yesllRespHtml=".$yesllRespHtml); |
结果运行出错：
| Warning: fsockopen() [function.fsockopen]: unable to connect to http://www.yell.com/:-1 (Unable to find the socket transport "http" – did you forget to enable it when you configured PHP?) in xxx.php on line 27 |
【解决过程】
1. 参考了：
fsock: Unable to find the socket transport “http”
看到其解释说fsockopen不支持Laye5+，所以不能直接给url地址，而只能给ip地址。
然后其建议用curl extension。
2.所以去找找php的curl extension。
然后找到：
好像是用其实现url的访问，很是麻烦，需要类似于这样的代码：
1 2 3 4 5 6 7 8 | $ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_HEADER, TRUE);curl_setopt($ch, CURLOPT_NOBODY, TRUE); // remove bodycurl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);$head = curl_exec($ch);$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);curl_close($ch); |
3.重新参考官网的解释：
去把代码改改为：
1 | $fp = fsockopen($url, 80); |
结果还是同样错误：
| Warning: fsockopen() [function.fsockopen]: unable to connect to http://www.yell.com/:80 (Unable to find the socket transport "http" – did you forget to enable it when you configured PHP?) in xxx.php on line 27 |
4.把代码改为：
1 2 | $testHostname = "www.yell.com";$fp = fsockopen($testHostname, 80); |
然后就可以了。
然后可以看到打印输出了：
| Resource id #2 |
【总结】
把对应的url地址：
改为
xxx.xxx.com
然后再去调用fsockopen，记得port设置为80（默认是-1），就可以正常访问了：
1 2 | $testHostname = "www.yell.com";$fp = fsockopen($testHostname, 80); |
总之，使用fsockopen去获得网页内容，极其的不方便。还是尽量去想别的办法去获得网页内容吧。
