在PHP中使用参数调用外部网址

Question

I have been working to call external url from PHP (on submit) with parameter. I have looked different option ( curl , file_get_contents etc), but nothing seems to working.

This is how final url should look like:

http://XXXXX:8080/job/Clone_CentOS_VM/buildWithParameters?token=smlvyKf6tS&vm_user=temp&memory_mb=1024&num_cpus=1&eth0_ip=172.XX.XX.XXX&eth1_ip=192.XX.XX.XX

And with parameter it looks this way:

http://XXXXX:8080/job/Clone_CentOS_VM/buildWithParameters?token=smlvyKf6tS&vm_user=$login&memory_mb=$memory&num_cpus=$cpu&eth0_ip=$ip_172&eth1_ip=$ip_192";

Answer 1

You did not escaped the variables you used while creating the URL. If you placed variables in a string, you need to tell, what a variable is and what the string is.

For example, you could use bracers around the varibales:

$url = "http://XXXXX:8080/job/Clone_CentOS_VM/buildWithParameters?token=smlvyKf6tS&vm_user={$login}&memory_mb={$memory}&num_cpus={$cpu}&eth0_ip={$ip_172}&eth1_ip={$ip_192}";

Or exclude them from the string:

$url = "http://XXXXX:8080/job/Clone_CentOS_VM/buildWithParameters?token=smlvyKf6tS&vm_user=" . $login . "&memory_mb=" . $memory . "&num_cpus=" . $cpu . "&eth0_ip=" . $ip_172 . "&eth1_ip=" . $ip_192;

Answer 2

You have to use the correct quotation characters " instead of ' around the string or you might concat the parameters/strings using a .

A possible solution is:

$url = 'http://XXXXX:8080/job/Clone_CentOS_VM/buildWithParameters?token=smlvyKf6tS&vm_user='.$login.'&memory_mb='.$memory.'&num_cpus='.$cpu.'&eth0_ip='.$ip_172.'&eth1_ip='.$ip_192;

Answer 3

Build your url as a string then use file_get_contents()

$login = "userName";
$memory = "memoryValue";
$cpu = "cpuValue";
$ip = "127_0_100_"; 

$url = "http://XXXXX:8080/job/Clone_CentOS_VM/buildWithParameters?token=smlvyKf6tS&vm_user=" . $login . "&memory_mb=" . $memory . "&num_cpus=" . $cpu . "&eth0_ip=" . $ip . "_172&eth1_ip=" . $ip . "_192";

$content = file_get_contents($url);

Answer 4

Build your url with all define param as a string then use file_get_contents() or curl() .

$url = "http://XXXXX:8080/job/Clone_CentOS_VM/buildWithParameters?token=smlvyKf6tS&vm_user=".$login."&memory_mb=".$memory."&num_cpus=".$cpu."&eth0_ip=".$ip_172."&eth1_ip=".$ip_192;

1. with file_get_contents() :

   file_get_contents($url);

2. with curl()

     $request_headers[] = 'Content-Type:application/json'; if (!function_exists('curl_init')){ die('cURL is not installed. Install and try again.'); } $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET"); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 30); $result = curl_exec($ch);
