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。

其他回答
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}]');
}
}
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;
}
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 $result;
?>
如果你这样做的话,还有另一个CURL方法。
一旦您了解了PHP curl扩展的工作方式,将各种标志与setopt()调用结合起来,这就非常简单了。在这个例子中,我有一个变量$xml,它保存了我准备发送的xml -我将把它的内容发布到示例的测试方法。
$url = 'http://api.example.com/services/xmlrpc/';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
//process $response
首先初始化连接,然后使用setopt()设置一些选项。它们告诉PHP我们正在发出post请求,并且我们正在发送一些数据,提供数据。CURLOPT_RETURNTRANSFER标志告诉curl将输出作为curl_exec的返回值而不是输出。然后我们进行调用并关闭连接-结果显示在$response中。
我建议你使用开源包guzzle,它经过了完整的单元测试,并使用了最新的编码实践。
安装狂饮
转到项目文件夹中的命令行并键入以下命令(假设已经安装了包管理器编写器)。如果你需要如何安装Composer的帮助,你应该看看这里。
php composer.phar require guzzlehttp/guzzle
使用Guzzle发送POST请求
Guzzle的用法非常直接,因为它使用了一个轻量级的面向对象的API:
// Initialize Guzzle client
$client = new GuzzleHttp\Client();
// Create a POST request
$response = $client->request(
'POST',
'http://example.org/',
[
'form_params' => [
'key1' => 'value1',
'key2' => 'value2'
]
]
);
// Parse the response object, e.g. read the headers, body, etc.
$headers = $response->getHeaders();
$body = $response->getBody();
// Output headers and body for debugging purposes
var_dump($headers, $body);
