这篇文章主要介绍了PHP整合七牛实现上传文件的相关资料,需要的朋友可以参考下
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:
<?php /* * * @desc URL安全形式的base64编码 * @param string $str * @return string */function urlsafe_base64_encode($str){$find = array("+","http://www.jb51.net/");$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);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;} } ?>
