PHP致命錯誤：未捕獲HTTP_Request2_ConnectionException：無法連接到tls：//bingapis.azure-api.net:443

Question

我正在編寫我的第一個腳本以使用新的Bing搜索API，並且我一直收到錯誤。 根據我的研究，它可能與證書有關，但我不知道在哪里尋找解決方案。 我正在使用具有相同錯誤結果的Centos 6和7服務器。 以下是錯誤：

PHP Fatal error:  Uncaught HTTP_Request2_ConnectionException: Unable to connect to tls://bingapis.azure-api.net:443. Error: stream_socket_client(): unable to connect to tls://bingapis.azure-api.net:443 (Unknown error)
stream_socket_client(): Failed to enable crypto
stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed in /usr/share/pear/HTTP/Request2/Adapter/Socket.php on line 332
#0 /usr/share/pear/HTTP/Request2/Adapter/Socket.php(332): HTTP_Request2_SocketWrapper->__construct('tls://bingapis....', 10, Array)

#3 /usr/src/bingtest.php(33): HTTP_Request2->send()
#4 {main}
  thrown in /usr/share/pear/HTTP/Request2/SocketWrapper.php on line 134

有人可以建議我接下來要排除故障嗎？ 我只是復制並粘貼示例代碼： bing api示例php代碼

如下所示:(僅針對那些可能會問我插入我從Bing生成的API密鑰的人，我只是不想在此處包含它）

<?php
// This sample uses the Apache HTTP client from HTTP Components (http://hc.apache.org/httpcomponents-client-ga/)
require_once 'HTTP/Request2.php';

$request = new Http_Request2('https://bingapis.azure-api.net/api/v5/images/search');
$url = $request->getUrl();

$headers = array(
    // Request headers
    'Ocp-Apim-Subscription-Key' => '{subscription key}', // I did replace this with my key
);

$request->setHeader($headers);

$parameters = array(
    // Request parameters
    'q' => 'cats',
    'count' => '10',
    'offset' => '0',
    'mkt' => 'en-us',
    'safeSearch' => 'Moderate',
);

$url->setQueryVariables($parameters);

$request->setMethod(HTTP_Request2::METHOD_GET);

// Request body
$request->setBody("{body}");

try
{
    $response = $request->send();
    echo $response->getBody();
}
catch (HttpException $ex)
{
    echo $ex;
}

?>

這是代碼的修復，注釋標記了更改

<?php
// This sample uses the Apache HTTP client from HTTP Components (http://hc.apache.org/httpcomponents-client-ga/)
require_once 'HTTP/Request2.php';

//$request = new Http_Request2('https://bingapis.azure-api.net/api/v5.0/images/search');
$request = new Http_Request2('https://api.cognitive.microsoft.com/bing/v5.0/images/search');
$url = $request->getUrl();

// ######### To Fix the SSL issue ###########
$request->setConfig(array(
    'ssl_verify_peer'   => FALSE,
    'ssl_verify_host'   => FALSE
));
// ########################################


$headers = array(
    // Request headers
    'Ocp-Apim-Subscription-Key' => 'fakeasdfasdfasdfasdfasdf',
);

$request->setHeader($headers);

$parameters = array(
    // Request parameters
    'q' => 'cats',
    'count' => '10',
    'offset' => '0',
    'mkt' => 'en-us',
    'safeSearch' => 'Moderate',
);

$url->setQueryVariables($parameters);

$request->setMethod(HTTP_Request2::METHOD_GET);

// Request body
$request->setBody("{body}");

try
{
    $response = $request->send();
    echo $response->getBody();
}
catch (HttpException $ex)
{
    echo $ex;
}

?>
