php - Error: "Illegal characters found in URL" - Code: 3 -

i want info api , code like:

<?php   $curl = curl_init();   $authorization = "authorization: token token='xxxxxx'";   $header = curl_setopt($curl, curlopt_httpheader, array($authorization));   curl_setopt($curl, curlopt_url, "https://customr.heliumdev.com/api/v1/customers/xxxx");   $result = curl_exec($curl);   if(!curl_exec($curl)){       print_r('error: "' . curl_error($curl) . '" - code: ' .curl_errno($curl)."<br>");   }   curl_close($curl);   print_r(json_decode($result)); ?> 

and got error error: "illegal characters found in url" - code: 3

the origin curl should curl https://customr.heliumdev.com/api/v1/customers/xxxx --header "authorization: token token="xxx"", idear illegal characters?

i not reproduce problem.

however, suggest avoid unnecessary double-execution of curl_exec , use $result instead...

... $result = curl_exec($curl); if (!$result) {    ... }
