PHP integrates Qiniu to upload files,

Qiniu supports grabbing remote image API, use access_key secret_key url to generate access_token, add access_token in the header, and then post url The upload is complete.

Sample code:

<&#63;php 
/* 
 * 
 * @desc URL安全形式的base64编码 
 * @param string $str 
 * @return string 
 */ 
 
 
function urlsafe_base64_encode($str){ 
  $find = array("+","/"); 
  $replace = array("-", "_"); 
  return str_replace($find, $replace, base64_encode($str)); 
} 
 
/** 
 * generate_access_token 
 * 
 * @desc 签名运算 
 * @param string $access_key 
 * @param string $secret_key 
 * @param string $url 
 * @param array $params 
 * @return string 
 */ 
function generate_access_token($access_key, $secret_key, $url, $params = ''){ 
  $parsed_url = parse_url($url); 
  $path = $parsed_url['path']; 
  $access = $path; 
  if (isset($parsed_url['query'])) { 
    $access .= "&#63;" . $parsed_url['query']; 
  } 
  $access .= "\n"; 
  if($params){ 
    if (is_array($params)){ 
      $params = http_build_query($params); 
    } 
    $access .= $params; 
  } 
  $digest = hash_hmac('sha1', $access, $secret_key, true); 
  return $access_key.':'.urlsafe_base64_encode($digest); 
} 
 
/** 
 * 测试 
 */ 
 
$access_key = '''your access_key'; 
$secret_key = 'your secret_key'; 
 
$fetch = urlsafe_base64_encode('http://203.208.46.200/images/srpr/logo11w.png'); 
$to = urlsafe_base64_encode('ibeircn:11.jpg'); 
 
$url = 'http://iovip.qbox.me/fetch/'. $fetch .'/to/' . $to; 
 
$access_token = generate_access_token($access_key, $secret_key, $url); 
 
$header[] = 'Content-Type: application/json'; 
$header[] = 'Authorization: QBox '. $access_token; 
 
 
$con = send('iovip.qbox.me/fetch/'.$fetch.'/to/'.$to, $header); 
var_dump($con); 
 
function send($url, $header = '') { 
  $curl = curl_init($url); 
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
  curl_setopt($curl, CURLOPT_HEADER,1); 
  curl_setopt($curl, CURLOPT_HTTPHEADER, $header); 
  curl_setopt($curl, CURLOPT_POST, 1); 
 
  $con = curl_exec($curl); 
 
  if ($con === false) { 
    echo 'CURL ERROR: ' . curl_error($curl); 
  } else { 
    return $con; 
  } 
}
