实际上,我想读取搜索查询之后的内容,当它完成时。问题是URL只接受POST方法,它不采取任何行动与GET方法…
我必须在domdocument或file_get_contents()的帮助下读取所有内容。有没有什么方法可以让我用POST方法发送参数,然后通过PHP读取内容?

我更喜欢这个:
function curlPost($url, $data = NULL, $headers = []) {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 5); //timeout in seconds
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_ENCODING, 'identity');
if (!empty($data)) {
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
}
if (!empty($headers)) {
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
}
$response = curl_exec($ch);
if (curl_error($ch)) {
trigger_error('Curl Error:' . curl_error($ch));
}
curl_close($ch);
return $response;
}
使用的例子:
$response=curlPost("http://my.url.com", ["myField1"=>"myValue1"], ["myFitstHeaderName"=>"myFirstHeaderValue"]);

PHP5的无卷曲方法:
$url = 'http://server.com/path';
$data = array('key1' => 'value1', 'key2' => 'value2');
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }
var_dump($result);
有关该方法和如何添加头的更多信息,请参阅PHP手册,例如:
stream_context_create: http://php.net/manual/en/function.stream-context-create.php
根据主要答案,以下是我使用的方法:
function do_post($url, $params) {
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => $params
)
);
$result = file_get_contents($url, false, stream_context_create($options));
}
使用示例:
do_post('https://www.google-analytics.com/collect', 'v=1&t=pageview&tid=UA-xxxxxxx-xx&cid=abcdef...');
你可以使用cURL:
<?php
//The url you wish to send the POST request to
$url = $file_name;
//The data you want to send via POST
$fields = [
'__VIEWSTATE ' => $state,
'__EVENTVALIDATION' => $valid,
'btnSubmit' => 'Submit'
];
//url-ify the data for the POST
$fields_string = http_build_query($fields);
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
//So that curl_exec returns the contents of the cURL; rather than echoing it
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
//execute post
$result = curl_exec($ch);
echo $result;
?>
如果你碰巧使用Wordpress来开发你的应用(它实际上是一种获得授权、信息页面等非常简单的东西的方便方式),你可以使用下面的代码片段:
$response = wp_remote_post( $url, array('body' => $parameters));
if ( is_wp_error( $response ) ) {
// $response->get_error_message()
} else {
// $response['body']
}
它使用不同的方式来发出实际的HTTP请求,这取决于web服务器上可用的内容。有关更多详细信息,请参阅HTTP API文档。
如果你不想开发一个自定义主题或插件来启动Wordpress引擎,你可以在Wordpress根目录下的一个单独的PHP文件中执行以下操作:
require_once( dirname(__FILE__) . '/wp-load.php' );
// ... your code
它不会显示任何主题或输出任何HTML,只是hack away Wordpress api !
