我有这个PHP代码使用cURL解析来自Indeed.com的xml提要。我将服务器信息(例如REMOTE_ADDR和HTTP_USER_AGENT)传递到url的参数中,但它们没有被传递。
检查以下代码的这一部分。 '.geoCheckIP($_SERVER['REMOTE_ADDR']).'
这是正确的方法。在CURLOPT_URL =>中,当它是数组的一部分时,不确定它是否是正确的方法。
在cURL中使用数组时,将这些服务器片段传递到url参数的正确方法是什么,如CURLOPT_URL =>中的以下函数?
下面的php代码是我页面上的完整代码,因此您可以更好地了解正在发生的事情。
我试图检测用户城市,说明他们到达我的网站以显示他们当地的工作列表。 php代码有效,我可以在网页上回显城市状态,但它不会将相同的信息传递给数组中的curl_request()函数。请帮忙。
<?php
// Convert IP into city state country (Geo Location function)
function geoCheckIP($ip){
if(!filter_var($ip, FILTER_VALIDATE_IP))
{
throw new InvalidArgumentException("IP is not valid");
}
$response=@file_get_contents('http://www.netip.de/search?query='.$ip);
if (empty($response))
{
throw new InvalidArgumentException("Error contacting Geo-IP-Server");
}
$patterns=array();
$patterns["domain"] = '#Domain: (.*?) #i';
$patterns["country"] = '#Country: (.*?) #i';
$patterns["state"] = '#State/Region: (.*?)<br#i';
$patterns["town"] = '#City: (.*?)<br#i';
$ipInfo=array();
foreach ($patterns as $key => $pattern)
{
$ipInfo[$key] = preg_match($pattern,$response,$value) && !empty($value[1]) ? $value[1] : 'not found';
}
/*I've included the substr function for Country to exclude the abbreviation (UK, US, etc..)
To use the country abbreviation, simply modify the substr statement to:
substr($ipInfo["country"], 0, 3)
*/
$ipdata = $ipInfo["town"]. ", ".$ipInfo["state"]/*.", ".substr($ipInfo["country"], 4)*/;
return $ipdata;
}
// Indeed php function
function curl_request(){
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'http://api.indeed.com/ads/apisearch?publisher=&q=computer+repair&l='.geoCheckIP($_SERVER['REMOTE_ADDR']).'&sort=&radius=25&st=&jt=&start=&limit=&fromage=&highlight=1&filter=1&latlong=0&co=us&chnl=computer+help+wanted&userip='.$_SERVER['REMOTE_ADDR'].'&useragent='.$_SERVER['HTTP_USER_AGENT'].'&v=2',
));
$resp = curl_exec($curl);
curl_close($curl);
return $resp;
}
function xmlToArray($input, $callback = null, $recurse = false) {
$data = ((!$recurse) && is_string($input))? simplexml_load_string($input, 'SimpleXMLElement', LIBXML_NOCDATA): $input;
if ($data instanceof SimpleXMLElement) $data = (array) $data;
if (is_array($data)) foreach ($data as &$item) $item = xmlToArray($item, $callback, true);
return (!is_array($data) && is_callable($callback))? call_user_func($callback, $data): $data;
}
?>
功能调用
这是在正文中调用函数的方式
<ol>
<?php
for($i=0;$i<10;$i++){ // using for loop to show number of jobs
$resp=curl_request($i);
$arrXml = xmlToArray($resp);
$results=$arrXml['results'];
?>
<li>
<p><strong>Job :</strong> <a href="<?php echo $results['result'][$i]['url']; ?>" target="_blank"><?php echo $results['result'][$i]['jobtitle']; ?></a></p>
<p><strong>Company:</strong> <?php echo $results['result'][$i]['company']; ?></p>
<p><strong>Location:</strong> <?php echo $results['result'][$i]['formattedLocationFull']; ?></p>
<p><strong>Date Posted :</strong> <?php echo $results['result'][$i]['formattedRelativeTime'];?> on <?php echo $results['result'][$i]['date'];?></p>
<p><strong>Description :</strong> <?php echo $results['result'][$i]['snippet']; ?></p>
</li>
<?php } ?>
</ol>
什么有用
只有从CURLOPT_URL
中删除变量时,上面的代码才有效此作品
CURLOPT_URL => 'http://api.indeed.com/ads/apisearch?publisher=&q=computer+repair&l=city,state&sort=&radius=25&st=&jt=&start=&limit=&fromage=&highlight=1&filter=1&latlong=0&co=us&chnl=computer+help+wanted&userip=111.111.111.111&useragent=mozila&v=2',
这不起作用
CURLOPT_URL => 'http://api.indeed.com/ads/apisearch?publisher=&q=computer+repair&l='.geoCheckIP($_SERVER['REMOTE_ADDR']).'&sort=&radius=25&st=&jt=&start=&limit=&fromage=&highlight=1&filter=1&latlong=0&co=us&chnl=computer+help+wanted&userip='.$_SERVER['REMOTE_ADDR'].'&useragent='.$_SERVER['HTTP_USER_AGENT'].'&v=2',

此处不需要使用cURL,加载速度非常慢。这是一个非常简单的方法来获取纯PHP中的xml文档的结果,geoCheckIP函数完全使用它。
<?php
// Convert IP into city state country (Geo Location function)
function geoCheckIP($ip){
if(!filter_var($ip, FILTER_VALIDATE_IP))
{
throw new InvalidArgumentException('IP is not valid');
}
$response=@file_get_contents('http://www.netip.de/search?query='.$ip);
if (empty($response))
{
throw new InvalidArgumentException('Error contacting Geo-IP-Server');
}
$patterns=array();
$patterns["domain"] = '#Domain: (.*?) #i';
$patterns["country"] = '#Country: (.*?) #i';
$patterns["state"] = '#State/Region: (.*?)<br#i';
$patterns["town"] = '#City: (.*?)<br#i';
$ipInfo=array();
foreach ($patterns as $key => $pattern)
{
$ipInfo[$key] = preg_match($pattern,$response,$value) && !empty($value[1]) ? $value[1] : 'not found';
}
/*I've included the substr function for Country to exclude the abbreviation (UK, US, etc..)
To use the country abbreviation, simply modify the substr statement to:
substr($ipInfo["country"], 0, 3)
*/
$ipdata = $ipInfo["town"]. ", ".$ipInfo["state"]/*.", ".substr($ipInfo["country"], 4)*/;
return $ipdata;
}
// Indeed.com API URL parameters
$url = 'http://api.indeed.com/ads/apisearch'.'?';
$publisher = 'YOUR PUB NUMBER GOES HERE';
$q = 'title:(java or java+programmer or java+programming)';
$l = geoCheckIP($_SERVER['REMOTE_ADDR']);
$sort = 'date';
$radius = '20';
$st = '';
$jt = '';
$start = '0';
$limit = '25';
$fromage = '';
$highlight = '0';
$filter = '1';
$latlong = '0';
$co = 'us';
$chnl = 'YOUR CHANNEL NAME';
$userip = $_SERVER['REMOTE_ADDR'];
$useragent = isset($_SERVER['HTTP_USER_AGENT']) ? ($_SERVER['HTTP_USER_AGENT']) : 'unknown';
$v = '2';
然后,您在下面看到的其余代码将会显示在您希望输出显示的页面的<body>
标记下方。
<!-- BEGIN INDEED ORDERED LIST-->
<ol class="jobs">
<?php
$xml = simplexml_load_file($url."publisher=".$publisher."&q=".$q."&l=".$l."&sort=".$sort."&radius=".$radius."&st=".$st."&jt=".$jt."&start=".$start."&limit=".$limit."&fromage=".$fromage."&highlight=".$highlight."&filter=".$filter."&latlong=".$latlong."&co=".$co."&chnl=".$chnl."&userip=".$userip."&useragent=".$useragent."&v=".$v);
foreach($xml->results->result as $result) { ?>
<li class="job">
<div id="jobtitle"><strong><a onmousedown="<?php echo $result->onmousedown;?>" rel="nofollow" href="<?php echo $result->url;?>" target="_blank"><?php echo $result->jobtitle;?></a></strong></div>
<div id="company"><?php echo $result->company;?></div>
<div id="snippet">
<?php echo $result->snippet;?>
</div>
<div id="location"><strong>Location:</strong> <?php echo $result->formattedLocationFull;?></div>
<div id="date"><span class="posted">Posted <?php echo $result->formattedRelativeTime;?></span></div>
</li>
<?php } ?>
</ol>

这里有一个正确的解释: passing arrays as url parameter
您可以从那里获取语法并将其与curl一起使用!
一个函数示例,它可以帮助您以数组形式创建url-param:
public function createArrParam($key, $values) {
return implode('&' . $key . '[]=', array_map('urlencode', $values));
}
之后你只需拿走你的网址并将其与结果连接起来:
$values = array(1, 2, 3, 4, 5);
$url = 'http://stackoverflow.com?bla=blupp' . createArrParam('myArr', $values);
答案 2 :(得分:0)
像这样;
function curl_request()
{
// Get cURL resource
$curl = curl_init();
// Set some options
$curl_config = array(
CURLOPT_URL => 'http://api.indeed.com/ads/apisearch',
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_POSTFIELDS => array(
"publisher" => "",
"q" => "computer+repair",
"l" => $user_location,
"sort" => "",
"radius" => 25,
"st" => "",
"jt" => "",
"start" => "",
"limit" => "",
"fromage" => "",
"highlight" => 1,
"filter" => 1,
"latlong" => 0,
"co" => "us",
"chnl" => "computer+help+wanted",
"userip" => $user_ip,
"useragent" => $user_agent,
"v" => 2
)
);
curl_setopt_array($curl, $curl_config);
// Send the request & save response to $resp
$resp = curl_exec($curl);
// Close request to clear up some resources
curl_close($curl);
return $resp;
}
修改强> 可能有1个,可能有2个原因导致这不适合你;
1。你没有传递你在函数外定义的变量(我的第一个答案中也没有)。
要解决这个问题,您需要在函数定义中将它们传递给function curl_request($user_ip, $user_agent, $user_location)
,并在调用函数时传递它们。或者更改您在URL字符串中输入的方式;
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'http://api.indeed.com/ads/apisearch?publisher=&q=computer+repair&l='.geoCheckIP($_SERVER['HTTP_USER_AGENT']).'&sort=&radius=25&st=&jt=&start=&limit=&fromage=&highlight=1&filter=1&latlong=0&co=us&chnl=computer+help+wanted&userip='.$$_SERVER['REMOTE_ADDR'].'&useragent='.$_SERVER['HTTP_USER_AGENT'].'&v=2'
));
$_SERVER
是一个全局变量,所以它不需要作为参数传递给函数就可以这样工作。
2。您的通话api仅接受POST
请求GET
,在这种情况下,我的第一个示例无效,您的第一个示例应该可以正常工作通过点 1
