未收到 PUT 发布数据

Question

我正在使用 cURL 通过 PHP 向我的网站发送 PUT 请求：

$data = array("a" => 'hello');
$ch = curl_init('http://localhost/linetime/user/1');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($data));

$response = curl_exec($ch);
var_dump($response);

然后，我正在侦听此 PUT 请求，但没有收到该请求的任何数据。请问你能告诉我哪里出错了吗？

$putData = '';
$fp = fopen('php://input', 'r');
while (!feof($fp)) {
    $s = fread($fp, 64);
    $putData .= $s;
}
fclose($fp);
echo $putData;
exit;

确保指定内容长度标头并将帖子字段设置为字符串

$data = array("a" => 'hello');    
$fields = http_build_query($data)
$ch = curl_init('http://localhost/linetime/user/1');

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); 

//important
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Length: ' . strlen($fields))); 

curl_setopt($ch, CURLOPT_POSTFIELDS,$fields);

使用 HTTP 客户端类来帮助发送请求。有几个可用的，但我创建了一个 (https://github.com/broshizzledizzle/Http-Client) 可以为您提供帮助。

发出 PUT 请求：

<?php
require_once 'Http/Client.php';
require_once 'Http/Method.php';
require_once 'Http/PUT.php';
require_once 'Http/Request.php';
require_once 'Http/Response.php';
require_once 'Http/Uri.php';

use Http\Request;
use Http\Response;

header('Content-type:text/plain');

    $client = new Http\Client();


    //GET request
    echo $client->send(
        Request::create()
            ->setMethod(new Http\PUT())
            ->setUri(new Http\Uri('http://localhost/linetime/user/1'))
            ->setParameter('a', 'hello')
    )->getBody();

?>

处理 PUT 请求：

//simply print out what was sent:
switch($_SERVER['REQUEST_METHOD']) {
    case 'PUT':
        echo file_get_contents('php://input');

        break;
}

请注意，我的项目中有一个自动加载器，它将为我加载所有这些包含，但如果您不想走这条路，您可能需要考虑制作一个包含所有内容的文件。

无库：

//initialization code goes here

$requestBody = http_build_query(
    array('a'=> 'hello'),
    '',
    '&'
);

$fh = fopen('php://memory', 'rw');
fwrite($fh, $requestBody);  
rewind($fh); 

curl_setopt($this->curl, CURLOPT_INFILE, $fh);  
curl_setopt($this->curl, CURLOPT_INFILESIZE, strlen($requestBody));  
curl_setopt($this->curl, CURLOPT_PUT, true); 

//send request here

fclose($fh);

请注意，您使用流来发送数据。
