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?

这里有这样的代码:
<?php
$postdata = http_build_query(
array(
'name' => 'Robert',
'id' => '1'
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('http://localhost:8000/api/test', false, $context);
echo $result;?>

我做了一个函数来请求一个使用JSON的帖子:
const FORMAT_CONTENT_LENGTH = 'Content-Length: %d';
const FORMAT_CONTENT_TYPE = 'Content-Type: %s';
const CONTENT_TYPE_JSON = 'application/json';
/**
* @description Make a HTTP-POST JSON call
* @param string $url
* @param array $params
* @return bool|string HTTP-Response body or an empty string if the request fails or is empty
*/
function HTTPJSONPost(string $url, array $params)
{
$content = json_encode($params);
$response = file_get_contents($url, false, // do not use_include_path
stream_context_create([
'http' => [
'method' => 'POST',
'header' => [ // header array does not need '\r\n'
sprintf(FORMAT_CONTENT_TYPE, CONTENT_TYPE_JSON),
sprintf(FORMAT_CONTENT_LENGTH, strlen($content)),
],
'content' => $content
]
])); // no maxlength/offset
if ($response === false) {
return json_encode(['error' => 'Failed to get contents...']);
}
return $response;
}
上面的答案对我不起作用。这是第一个完美运行的解决方案:
$sPD = "name=Jacob&bench=150"; // The POST Data
$aHTTP = array(
'http' => // The wrapper to be used
array(
'method' => 'POST', // Request Method
// Request Headers Below
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $sPD
)
);
$context = stream_context_create($aHTTP);
$contents = file_get_contents($sURL, false, $context);
echo $contents;
我更喜欢这个:
function curlPost($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"]);
这里有这样的代码:
<?php
$postdata = http_build_query(
array(
'name' => 'Robert',
'id' => '1'
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('http://localhost:8000/api/test', false, $context);
echo $result;?>
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:
