在PHP中使用飛行定價Skyscanner上，阿比獲取錯誤

Question

我下面的鏈接訪問飛行實時價格 Skyscanner API for all airport locations and Travel API using CURL

i have replace api key with my apikey. 

PHP代碼：

<?php 

    $varApiKey = '?apiKey=API KEY'; 
    $country_code = 'IR'; 
    $originplace = '51.845159,-8.492835-latlong'; 
    $curency = 'EUR'; 
    $destination = 'DUB-iata'; 
    $start_date = date('Y-m-d'); 
    $dateOneMonth = strtotime($start_date); 
//$end_date = date("Y-m-d", strtotime("+1 month", $dateOneMonth)); 
    $end_date = ''; 
    $audult = '1'; 
    $cabinclass = 'Economy'; 
    $locationschema = 'iata'; 
    $grouppricing = $preferDirects = 'true'; 

    $query = "&country=" . $country_code; 
    $query .= "&currency=" . $curency; 
    $query .= "&locale=en-IE"; 
    $query .= "&originplace=" . $originplace; 
    $query .= "&destinationplace=" . $destination; 
    $query .= "&inbounddate=" . $end_date; 
    $query .= "&outbounddate=" . $start_date; 
    $query .= "&adults=" . $audult; 
    $query .="&locationschema=" . $locationschema; 
    $query .="&cabinclass=" . $cabinclass; 
    $query .="&preferDirects=" . $preferDirects; 
    $query .="&grouppricing=" . $grouppricing; 


    $apiParamsUrl = "http://partners.api.skyscanner.net/apiservices/pricing/v1.0/" . $varApiKey . $query . ""; 

    $apiParamsStr = parse_url($apiParamsUrl, PHP_URL_QUERY); // get the query string parametures 
    parse_str($apiParamsStr, $apiParamsArray); 


    // parse into an array 
// the api url. First we need to request for a session 
    $apiSessionUrl = 'http://partners.api.skyscanner.net/apiservices/pricing/v1.0'; 

//open connection 
    $ch = curl_init(); 

//set the url, number of POST vars, POST data 
    curl_setopt($ch, CURLOPT_URL, $apiSessionUrl); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded', 'Accept: application/json')); // make api return json data 
    curl_setopt($ch, CURLOPT_POST, count($apiParamsArray)); // set how many fiels 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $apiParamsStr); // set the fields 
// caputre the headers 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_VERBOSE, 1); 
    curl_setopt($ch, CURLOPT_HEADER, 1); 

//execute post 
    $response = curl_exec($ch); 



// get the headers 
    $header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE); 
    $header = substr($response, 0, $header_size); 
    $body = substr($response, $header_size); 

//close connection 
    curl_close($ch); 

// print_r($response); 
// die(); 
// get the api session url 
    preg_match('~Location: ([^\s]+)~', $header, $matches); 
    $apiSessionUrl = $matches[1]; 

// add on the api key for the session 
    $apiSessionUrl .= $varApiKey; 

// get the json data 
    $data = file_get_contents($apiSessionUrl); 

// decode the json 
    $array = json_decode($data, true); 

// dump json array`enter code here` 
    printf('<pre>Poll Data %s</pre>', print_r($array, true)); 


?> 

乳寧我得到這個代碼後錯誤

Notice: Undefined offset: 1 in C:\xampp\htdocs\flyoften\price.php on line 64 

Warning: file_get_contents(?apiKey=in642116937922782575755373514454): failed to open stream: No such file or directory in C:\xampp\htdocs\flyoften\price.php on line 70 
Poll Data 

如何解決這個問題。好心幫助 1：是skyscanner航班直播價格api禁用？

Answer 1

的的preg_match不給這裏的任何結果，沒有$matches[1]：

preg_match('~Location: ([^\s]+)~', $header, $matches); 
$apiSessionUrl = $matches[1]; 

應測試的preg_match的結果：

if (preg_match('~Location: ([^\s]+)~', $header, $matches)) { 
    $apiSessionUrl = $matches[1]; 
} else { 
    // There is a problem !!! 
    // do something ... or exit the program 
}
