"\r\n"; $http_request .= "\r\n"; $http_request .= $data; $response = ''; if (($fs = @fsockopen($host, $port, $errno, $errstr, 10)) == false) { die ('Could not open socket! ' . $errstr); } fwrite($fs, $http_request); while (!feof($fs)) $response .= fgets($fs, 1160); fclose($fs); $response = explode("\r\n\r\n", $response, 2); return $response[1]; } } ?> ``` 放在同级目录即可。 ![](https://puep.qpic.cn/coral/Q3auHgzwzM4fgQ41VTF2rDhibzpcv3KNVWcIKVGHpK5U7DH7DOrgM5A/0) 最后修改:2022 年 06 月 05 日 © 允许规范转载 打赏 赞赏作者 支付宝微信 赞 如果觉得我的文章对你有用,请随意赞赏
