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
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, $requestArr), '[{"error":false}]');
}
}
其他回答
我使用下面的函数来使用curl发布数据。$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。
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 $response;
}
我正在寻找一个类似的问题,并找到了更好的方法来做到这一点。所以它开始了。
您可以简单地在重定向页面(例如page1.php)上放置以下行。
header("Location: URL", TRUE, 307); // Replace URL with to be redirected URL, e.g. final.php
我需要这个来重定向REST API调用的POST请求。这个解决方案能够重定向post数据以及自定义头值。
这里是参考链接。
我更喜欢这个:
function curlPost($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"]);
