Question

我在打开这个使用fopen

的网址时遇到了麻烦

http://sim8430.agni.lindenlab.com:12046/cap/ccab53e3-49d8-c4f8-b3ad-51ff22c1fa17/

然而，由于某种原因，它会默默地失败，它会打开其他网址，但没有像上面那样的网址

事实上，它不会给出错误并不是真正的问题，不加载是我试图解决的问题

$file = fopen("http://sim8430.agni.lindenlab.com:12046/cap/ccab53e3-49d8-c4f8-b3ad-51ff22c1fa17/", "r") or exit("Unable to open file!");

Answer 1

像这样抓住它

// add extensive logging
error_reporting(E_ALL);
$file = fopen("http://sim8430.agni.lindenlab.com:12046/cap/xyz/", "r");
if($file === false) { 
      // try through socket open
      $file = fsockopen("sim8430.agni.lindenlab.com", 12046, $errno, $errstr);
      if($file == false && $errno == 0) die("Socket initialization failed");
      else if(!$file) {
          die($errstr);
      } else {
          $out = "GET /cap/xyz/ HTTP/1.1\r\n";
          $out .= "Host: sim8430.agni.lindenlab.com\r\n";
          $out .= "Connection: Close\r\n\r\n";
          fwrite($file, $out);
      }
}
if($file) {
    while (!feof($file)) {
        $contents = fgets($file, 128);
    }
    fclose($file);
}

在读取/解析WWW服务器上的文件内容时，始终使用cURL。
