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:
-
- /*
- *
- * @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 .= "?" . $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);
