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?

当前回答
尝试PEAR的HTTP_Request2包来轻松地发送POST请求。或者,您可以使用PHP的curl函数或使用PHP流上下文。
HTTP_Request2还使模拟服务器成为可能,因此您可以轻松地对代码进行单元测试

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 $contents;
根据主要答案,以下是我使用的方法:
function do_post($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($options));
}
使用示例:
do_post('https://www.google-analytics.com/collect', 'v=1&t=pageview&tid=UA-xxxxxxx-xx&cid=abcdef...');
我使用下面的函数来使用curl发布数据。$data是一个要发布的字段数组(将使用http_build_query()正确编码)。
function httpPost($url, $data)
{
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($curl);
curl_close($curl);
return $response;
}
@Edward提到http_build_query()可能被省略,因为curl将正确编码传递给CURLOPT_POSTFIELDS参数的数组,这是正确的,但请注意,在这种情况下,数据将使用multipart/form-data进行编码,这可能不可取,因为一些端点希望数据使用application/x-www-form-urlencoded进行编码。当像上面的函数一样使用http_build_query()时,数据将使用application/x-www-form-urlencoded进行编码。
我正在寻找一个类似的问题,并找到了更好的方法来做到这一点。所以它开始了。
您可以简单地在重定向页面(例如page1.php)上放置以下行。
header("Location: URL", TRUE, 307); // Replace URL with to be redirected URL, e.g. final.php
我需要这个来重定向REST API调用的POST请求。这个解决方案能够重定向post数据以及自定义头值。

我想补充一些关于Fred Tanrikut基于卷曲的回答的想法。我知道大部分问题已经写在上面的答案中,但我认为给出一个包括所有问题的答案是个好主意。
下面是我编写的基于curl进行HTTP-GET/POST/PUT/DELETE请求的类,只涉及响应体:
class HTTPRequester {
/**
* @description Make HTTP-GET call
* @param $url
* @param array $params
* @return HTTP-Response body or an empty string if the request fails or is empty
*/
public static function HTTPGet($url, array $params) {
$query = http_build_query($params);
$ch = curl_init($url.'?'.$query);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
/**
* @description Make HTTP-POST call
* @param $url
* @param array $params
* @return HTTP-Response body or an empty string if the request fails or is empty
*/
public static function HTTPPost($url, array $params) {
$query = http_build_query($params);
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $query);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
/**
* @description Make HTTP-PUT call
* @param $url
* @param array $params
* @return HTTP-Response body or an empty string if the request fails or is empty
*/
public static function HTTPPut($url, array $params) {
$query = \http_build_query($params);
$ch = \curl_init();
\curl_setopt($ch, \CURLOPT_RETURNTRANSFER, true);
\curl_setopt($ch, \CURLOPT_HEADER, false);
\curl_setopt($ch, \CURLOPT_URL, $url);
\curl_setopt($ch, \CURLOPT_CUSTOMREQUEST, 'PUT');
\curl_setopt($ch, \CURLOPT_POSTFIELDS, $query);
$response = \curl_exec($ch);
\curl_close($ch);
return $response;
}
/**
* @category Make HTTP-DELETE call
* @param $url
* @param array $params
* @return HTTP-Response body or an empty string if the request fails or is empty
*/
public static function HTTPDelete($url, array $params) {
$query = \http_build_query($params);
$ch = \curl_init();
\curl_setopt($ch, \CURLOPT_RETURNTRANSFER, true);
\curl_setopt($ch, \CURLOPT_HEADER, false);
\curl_setopt($ch, \CURLOPT_URL, $url);
\curl_setopt($ch, \CURLOPT_CUSTOMREQUEST, 'DELETE');
\curl_setopt($ch, \CURLOPT_POSTFIELDS, $query);
$response = \curl_exec($ch);
\curl_close($ch);
return $response;
}
}
改进
Using http_build_query to get the query-string out of an request-array.(you could also use the array itself, therefore see: http://php.net/manual/en/function.curl-setopt.php) Returning the response instead of echoing it. Btw you can avoid the returning by removing the line curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);. After that the return value is a boolean(true = request was successful otherwise an error occured) and the response is echoed. See: http://php.net/en/manual/function.curl-exec.php Clean session closing and deletion of the curl-handler by using curl_close. See: http://php.net/manual/en/function.curl-close.php Using boolean values for the curl_setopt function instead of using any number.(I know that any number not equal zero is also considered as true, but the usage of true generates a more readable code, but that's just my opinion) Ability to make HTTP-PUT/DELETE calls(useful for RESTful service testing)
用法示例
GET
$response = HTTPRequester::HTTPGet("http://localhost/service/foobar.php", array("getParam" => "foobar"));
POST
$response = HTTPRequester::HTTPPost("http://localhost/service/foobar.php", array("postParam" => "foobar"));
PUT
$response = HTTPRequester::HTTPPut("http://localhost/service/foobar.php", array("putParam" => "foobar"));
删除
$response = HTTPRequester::HTTPDelete("http://localhost/service/foobar.php", array("deleteParam" => "foobar"));
测试
您还可以通过使用这个简单的类来进行一些很酷的服务测试。
class HTTPRequesterCase extends TestCase {
/**
* @description test static method HTTPGet
*/
public function testHTTPGet() {
$requestArr = array("getLicenses" => 1);
$url = "http://localhost/project/req/licenseService.php";
$this->assertEquals(HTTPRequester::HTTPGet($url, $requestArr), '[{"error":false,"val":["NONE","AGPL","GPLv3"]}]');
}
/**
* @description test static method HTTPPost
*/
public function testHTTPPost() {
$requestArr = array("addPerson" => array("foo", "bar"));
$url = "http://localhost/project/req/personService.php";
$this->assertEquals(HTTPRequester::HTTPPost($url, $requestArr), '[{"error":false}]');
}
/**
* @description test static method HTTPPut
*/
public function testHTTPPut() {
$requestArr = array("updatePerson" => array("foo", "bar"));
$url = "http://localhost/project/req/personService.php";
$this->assertEquals(HTTPRequester::HTTPPut($url, $requestArr), '[{"error":false}]');
}
/**
* @description test static method HTTPDelete
*/
public function testHTTPDelete() {
$requestArr = array("deletePerson" => array("foo", "bar"));
$url = "http://localhost/project/req/personService.php";
$this->assertEquals(HTTPRequester::HTTPDelete($url, $requestArr), '[{"error":false}]');
}
}
