如何使用PHP发送POST请求？ [英] How do I send a POST request with PHP?

问题描述

实际上我想阅读搜索查询后的内容，完成后。问题是URL只接受 POST 方法，并且它不会对 GET 方法采取任何操作...

Actually I want to read the contents that come after the search query, when it is done. The problem is that the URL only accepts POST methods, and it does not take any action with GET method...

我必须在 domdocument 或 file_get_contents（）<的帮助下阅读所有内容/ code>。是否有任何方法可以让我使用 POST 方法发送参数，然后通过 PHP 读取内容？

I have to read all contents with the help of domdocument or file_get_contents(). Is there any method that will let me send parameters with POST method and then read the contents via PHP?

推荐答案

使用PHP5的无CURL方法：

CURL-less method with PHP5:

$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);

有关方法以及如何添加标题的详细信息，请参阅PHP手册，例如：

See the PHP manual for more information on the method and how to add headers, for example:

• stream_context_create ： http://php.net/manual/en/function.stream-context-create.php

• stream_context_create: http://php.net/manual/en/function.stream-context-create.php
