七牛支持抓取远程图片 API，用 access_key + secret_key + url 生成 access_token,把 access_token 加在 header 里，然后向 post url 就完成上传了。
Sample code:
$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 .= "?" . $parsed_url['query'];
}
$access .= "\n";
if($params){
if (is_array($params)){
$params = http_build_query($params);
}
$access .= $params;
}
$digest = hash_hmac('sha1',$access,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,$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,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;
}
}
?>
