PHP integrates Qiniu to upload files

This article mainly introduces the relevant information about integrating Qiniu with PHP to realize uploading files. Friends in need can refer to it

Qiniu supports grabbing remote image API, use access_key secret_key url to generate access_token, and put access_token Add it to the header and upload it to the post url to complete the upload.

Sample code:

<?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 = &#39;&#39;){ 
  $parsed_url = parse_url($url); 
  $path = $parsed_url[&#39;path&#39;]; 
  $access = $path; 
  if (isset($parsed_url[&#39;query&#39;])) { 
    $access .= "?" . $parsed_url[&#39;query&#39;]; 
  } 
  $access .= "\n"; 
  if($params){ 
    if (is_array($params)){ 
      $params = http_build_query($params); 
    } 
    $access .= $params; 
  } 
  $digest = hash_hmac(&#39;sha1&#39;, $access, $secret_key, true); 
  return $access_key.&#39;:&#39;.urlsafe_base64_encode($digest); 
} 
 
/** 
 * 测试 
 */ 
 
$access_key = &#39;&#39;&#39;your access_key&#39;; 
$secret_key = &#39;your secret_key&#39;; 
 
$fetch = urlsafe_base64_encode(&#39;http://203.208.46.200/images/srpr/logo11w.png&#39;); 
$to = urlsafe_base64_encode(&#39;ibeircn:11.jpg&#39;); 
 
$url = &#39;http://iovip.qbox.me/fetch/&#39;. $fetch .&#39;/to/&#39; . $to; 
 
$access_token = generate_access_token($access_key, $secret_key, $url); 
 
$header[] = &#39;Content-Type: application/json&#39;; 
$header[] = &#39;Authorization: QBox &#39;. $access_token; 
 
 
$con = send(&#39;iovip.qbox.me/fetch/&#39;.$fetch.&#39;/to/&#39;.$to, $header); 
var_dump($con); 
 
function send($url, $header = &#39;&#39;) { 
  $curl = curl_init($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 ($con === false) { 
    echo &#39;CURL ERROR: &#39; . curl_error($curl); 
  } else { 
    return $con; 
  } 
} 
?>
