php curl訪問接口

1.post

public function getClassInfo($user_id, $token)
	{
		include(APPPATH."config/config.php");
		$pPostData = Array();
		$pPostData["token"] = $token;
		$pPostData["user_id"] = $user_id;
		
		$myurl = $config["api_esmart_get_class_info"];
		
		//跨域訪問測試(使用CURL)
		$ch = curl_init() ;
		//set the url, number of POST vars, POST data
		curl_setopt($ch, CURLOPT_URL,$myurl) ;
		$headers = array(
				"Cache-Control: no-cache",
		);
		curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);      //不使用緩存
		curl_setopt($ch, CURLOPT_POST,count($pPostData)) ;   // 啓用時會發送一個常規的POST請求，類型爲：application/x-www-form-urlencoded，就像表單提交的一樣。
		curl_setopt($ch, CURLOPT_POSTFIELDS,$pPostData);     // 在HTTP中的“POST”操作。如果要傳送一個文件，需要一個@開頭的文件名
		ob_start();
		curl_exec($ch);
		$result = ob_get_contents() ;
		ob_end_clean();
		//close connection
		curl_close($ch) ;
		return $result;
	}

public function getStudentList($pSchoolID, $pYearID, $pGradeID, $pClazzID, $pOffset, $pPageSize)
	{
		include(APPPATH."config/config.php");
		
		$myurl = sprintf($config["api_getstudentlist"],$pSchoolID,$pYearID,$pGradeID,$pClazzID,$pOffset,$pPageSize);
		//跨域訪問測試(使用CURL)
		$ch = curl_init($myurl);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ;     // 獲取數據返回
		$headers = array(
				"Cache-Control: no-cache",
		);
		curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);      //不使用緩存
		curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ;     // 在啓用 CURLOPT_RETURNTRANSFER 時候將獲取數據返回
		$output = curl_exec($ch) ;
		return $output;
