file_get_contents on other port

问题

I must contact services rest on different ports by 80, but the function file_get_contents () returns an error: failed to open stream: Connection refused

$url = "http://nexusdigital.agency:81/API/....";

$result = file_get_contents($url, false);

How can I configure the reading on other ports?

回答1:

Use CURL :

<?php
$curl = curl_init('http://nexusdigital.agency/API/....'); 
curl_setopt($curl, CURLOPT_PORT, 81); 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 81); 
$result = curl_exec($curl);
?>

Well, if it doesn't work for you (whatever the reason) you can try using CURL http://php.net/curl

<?php
$tuCurl = curl_init(); 
curl_setopt($tuCurl, CURLOPT_URL, "http://nexusdigital.agency/API/...."); 
curl_setopt($tuCurl, CURLOPT_PORT , 81); 
curl_setopt($tuCurl, CURLOPT_VERBOSE, 0); 
curl_setopt($tuCurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($tuCurl, CURLOPT_CONNECTTIMEOUT, 5); // 5 seconds timeout

$tuData = curl_exec($tuCurl); 
curl_close($tuCurl);
