这里只使用了一个没有cURL的命令。超级简单。

echo file_get_contents('https://www.server.com', false, stream_context_create([
    'http' => [
        'method' => 'POST',
        'header'  => "Content-type: application/x-www-form-urlencoded",
        'content' => http_build_query([
            'key1' => 'Hello world!', 'key2' => 'second value'
        ])
    ]
]));

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。

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。

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 !

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}]');
    }
}
