Question

我在import.io上使用web scraper服务尝试了Owl数据集示例，但是当我尝试将它与示例PHP集成时，我不断得到'NULL'作为结果。

$userGuid = "MY_USER_ID";
$apiKey = "MY_API_KEY";

// Issues a query request to import.io
function query($connectorGuid, $input, $userGuid, $apiKey) {

    $url = "https://query.import.io/store/connector/" . $connectorGuid . "/_query?_user=" . urlencode($userGuid) . "&_apikey=" . urlencode($apiKey);

    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        "Content-Type: application/json",
        "import-io-client: import.io PHP client",
        "import-io-client-version: 2.0.0"
    ));
    curl_setopt($ch, CURLOPT_POSTFIELDS,  json_encode(array("input" => $input)));
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    $result = curl_exec($ch);
    curl_close($ch);

    return json_decode($result);
}

// Query for tile owltest
echo "Test";
$result = query("71e57dbc-9996-4fa3-8715-c564a347d002", array(
  "webpage/url" => "http://owlkingdom.com/",
), $userGuid, $apiKey, false);
var_dump($result);

我在几台服务器上试过这个并没有快乐。无论如何我还没有修改代码。如果我将URL弹出到浏览器中，我会在JSON中将数据集返回给我。

其他人对示例脚本有任何问题吗？

已更改

$url = "https://query.import.io/store/connector/" . $connectorGuid . "/_query?_user=" . urlencode($userGuid) . "&_apikey=" . urlencode($apiKey);

到

$url = "http://query.import.io/store/connector/" . $connectorGuid . "/_query?_user=" . urlencode($userGuid) . "&_apikey=" . urlencode($apiKey);

解决了这个问题。我相信如果需要安全连接，您也可以修改curl选项以接受站点的SSL证书。
