尝试使用Windows Azure新的基于Bing的API创建新的API请求时,请使用以下代码

$url= 'https://'.$this->m_host.'/Web?Query={keyword}&Adult=%27Off%27&$top=50&$format=Atom';     

        $url=str_replace('{keyword}', urlencode($this->m_keywords), $url);

        // Replace this value with your account key
                    $accountKey = $this->key;

                    $WebSearchURL = $url;

                    $context = stream_context_create(array(
                        'http' => array(
                            'proxy' => 'tcp://127.0.0.1:8888',
                            'request_fulluri' => true,
                            'header'  => "Authorization: Basic " . base64_encode($accountKey . ":" . $accountKey)
                        )
                    ));

                    $request = $WebSearchURL;
                    $response = file_get_contents($request, 0, $context);

        print_r($response);

我收到以下错误。

Warning: file_get_contents() [function.file-get-contents]: 
Couldn't connect to server in /home/xxxxx on line 43

Warning: file_get_contents(https://api.datamarket.azure.com/ 
failed to open stream: operation failed in /home/xxxx/ bing_search.php on line 43

知道为什么会失败吗?或者最好使用CURL库而不是file_get_contents()?

以下代码适用于我,它是搜索新闻,但它也适用于网络搜索。

只需将appkey替换为您的appkey,保留用户名(即username),因为服务器会忽略它

function getBingResult($keyword)
{
    $credentials = "username:appkey";
    $url= "https://api.datamarket.azure.com/Data.ashx/Bing/Search/v1/News?Query=%27{keyword}%27". "&\$format=json";        
    $url=str_replace('{keyword}', urlencode($keyword), $url);
    $ch = curl_init();
    $headers = array(
       "Authorization: Basic " . base64_encode($credentials)
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,5);
    curl_setopt($ch, CURLOPT_FAILONERROR, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_AUTOREFERER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($session, CURLOPT_VERBOSE, TRUE); 

    $rs = curl_exec($ch);
    $jsonobj = json_decode($rs);
    curl_close($ch);    
    return $jsonobj;
}

测试功能:

$bingResult = getBingResult("John");
foreach($bingResult->d->results as $value)
{   
    echo '<pre>'."URL:". $value->Url.'</pre>';
    echo '<pre>'."Title:". $value->Title.'</pre>';
    echo '<pre>'."Description:". $value->Description.'</pre>';   
    echo '<pre>'."Source:". $value->Source.'</pre>';   
    echo '<pre>'."Date:". $value->Date.'</pre>';   
}

file_get_contentsCURL适用于Bing API,您可以使用适用于您系统的内容以及您认为合适的内容。

首先,我会检查您的服务器是否可以连接到Windows Azure服务器。尝试从命令行运行ping然后运行wget以查看是否可以。你通过代理吗?您需要在流上下文中设置这些详细信息。

我不确定你设置的$this->m_host是什么,但新的Bing API应该是: https://api.datamarket.azure.com/Bing/Search/https://api.datamarket.azure.com/Bing/SearchWeb/。网址https://api.datamarket.azure.com/Web返回无效。

以下是Search API的工作示例,只需用&#34; XXXX&#34;替换您的访问密钥。即使我浪费了几个小时才能使用cURL工作,但它失败的原因是&#34; CURLOPT_SSL_VERIFYPEER&#34;在当地:(

$process = curl_init('https://api.datamarket.azure.com/Bing/Search/Web?Query=%27xbox%27');
curl_setopt($process, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($process, CURLOPT_USERPWD, "username:XXXX");
curl_setopt($process, CURLOPT_TIMEOUT, 30);
curl_setopt($process, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($process, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($process);

# Deliver
return $response;

# Have a great day!
curl_close($process);

1。)您不需要str_replace()。直接在url中使用var:
$url= 'https://'.$this->m_host.'/Web?Query='.urlencode($this->m_keywords).'&Adult=%27Off%27&$top=50&$format=Atom';

2。)您定义了三个具有相同值的不同变量:
$WebSearchURL = $url;
$request = $WebSearchURL;

仅使用$url

3。)base64_encode($accountKey . ":" . $accountKey)可以缩减为base64_encode(":" . $accountKey)

4。)将Accept-Encoding: gzip添加到标题中以减少流量并提高速度。

5.)你的问题应该是这一行:
'proxy' => 'tcp://127.0.0.1:8888',

将其删除或将其更改为正确的值。
