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);
