怎么样使用SAE实时日志接口SDK?
本文实例讲述了SAE实时日志接口SDK用法。分享给大家供大家参考,具体如下:
新浪SAE是新浪研发中心开发的国内首个公有云平台,从2009年开始到现在也是也来越成熟,开放了很多接口以及服务供开发者使用。这次为了方便开发者调试分析,SAE新增实时日志查询接口。今后您可以通过API对日志信息进行筛选,并下载所需的实时日志。但是新浪SAE官方只给出的Python的实现,这里给出PHP版本的接口调用SDK
class SaeApiHandler{ /** * 定义accessKey */ private $accessKey; /** * 定义secretKey */ private $secretKey; /** * 定义时间戳 */ private $timestamp; /** * 构造函数 */ public function __construct($key,$sec){ $this->accessKey = $key; $this->secretKey = $sec; $this->timestamp = time(); } /** * 重载get方法 */ public function __call($name,$arg){ $ret = array(); if (is_array($arg[0])) { $len = count($arg); for ($i=0; $i < $len; $i++) { $ret[$i] = $arg[$i]['fop'] ? $this->$name($arg[$i]['service'],$arg[$i]['date'],$arg[$i]['ident'],$arg[$i]['fop']):$this->$name($arg[$i]['service'],$arg[$i]['date'],$arg[$i]['ident']); } }else{ $ret = $arg[3] ? $this->$name($arg[0],$arg[1],$arg[2],$arg[3]) : $this->get($arg[0],$arg[1],$arg[2]); } return $ret; } /** * 获取日志 * @param string 需要的日志 * @param string 时间 * @param string 日志类型 * @param string 过滤符 * @return array */ private function getLog($service,$date,$ident,$fop=null){ if ($fop) { $uri = '/log/'.$service.'/'.$date.'/'.$_SERVER['HTTP_APPVERSION'].'-'.$ident.'.log?'.$fop; }else{ $uri = '/log/'.$service.'/'.$date.'/'.$_SERVER['HTTP_APPVERSION'].'-'.$ident.'.log'; } $ret = explode(PHP_EOL,$this->get($uri)); array_splice($ret,0,7); array_pop($ret); return $ret; } private function get($uri){ $host = 'http://g.sae.sina.com.cn'.$uri; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$host); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, $this->saeHeader($uri)); curl_setopt($ch, CURLOPT_HEADER, 1); $ret = curl_exec($ch); curl_close($ch); return $ret; } /** * SAE请求头 * @return array */ private function saeHeader($uri){ return array( 'Host: g.sae.sina.com.cn', 'Accept: text/plain', 'x-sae-accesskey: '.$this->accessKey, 'x-sae-timestamp: '.$this->timestamp, 'Authorization: '. $this->getAuthorization($uri) ); } /** * 获取gAuthorization */ private function getAuthorization($uri){ $header = array( 'x-sae-timestamp' => $this->timestamp, 'x-sae-accesskey' => strtolower($this->accessKey) ); ksort($header); $sae_header = array('GET',$uri); foreach ($header as $key => $value) { $sae_header[count($sae_header)] = $key.':'.$value; } $ret = implode(PHP_EOL, $sae_header); $auth = 'SAEV1_HMAC_SHA256 '.base64_encode(hash_hmac('sha256',$ret,$this->secretKey,true)); return $auth; } }
使用也很简单,实例化SaeApiHandler类,调用getLog()方法即可。该方法可以传递数组参数或者字符串,具体可以到SAE文档看,如果需要返回多组日志,则传递多个数组即可。
$test = new SaeApiHandler(SAE_ACCESSKEY,SAE_SECRETKEY); $arr1 = array( 'service'=>'http', 'date'=>'2015-07-03', 'ident'=>'access', 'fop'=>'head/1/5' ); $arr2 = array( 'service'=>'http', 'date'=>'2015-07-03', 'ident'=>'access', 'fop'=>'head/1/5' ); $ret = $test->getLog($arr1,$arr2); var_dump($ret);
希望本文所述对大家PHP程序设计有所帮助。
