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);
