用PHP發送/接收PUT請求，無法解析請求主體？

Question

我正在嘗試構建一個RESTful APi。

我發送一個PUT請求像這樣：/ API /客戶/ 1

$data['name'] = 'test'; 

$ch = curl_init('myurl/api/'.$name); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT'); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
curl_setopt($ch, CURLINFO_HEADER_OUT, true); 
$results = json_decode(curl_exec($ch)); 

我傳遞的POSTFIELDS，我以爲會在請求主體的$數據列表。

當我去分析，我想：

$params = file_get_contents('php://input'); 

不過，我沒有看到我在任何地方通過變量。

任何意見將是有益的，謝謝。

Answer 1

的$params = file_get_contents('php://input');值將需要使用parse_str字符串：

$input = file_get_contents('php://input'); 
parse_str($input, $params); 
print_r($params); 

在某些情況下php://input還要注意只能讀一次，所以你可能需要存儲。

Answer 2

接受的答案將不適用於multipart/form-data，出於無奈，我寫了我自己的方法。這處理文件上傳和多維請求。

/** 
* @param string $formData Raw response request of type FormData 
* @param array $header Meta data for each part of the form data (optional) 
* @return array Processed form data 
*/ 
public function parse_form_data($formData, &$header) 
{ 
    $endOfFirstLine = strpos($formData, "\r\n"); 
    $boundary = substr($formData, 0, $endOfFirstLine); 
    // Split form-data into each entry 
    $parts = explode($boundary, $formData); 
    $return = []; 
    $header = []; 
    // Remove first and last (null) entries 
    array_shift($parts); 
    array_pop($parts); 
    foreach ($parts as $part) { 
     $endOfHead = strpos($part, "\r\n\r\n"); 
     $startOfBody = $endOfHead + 4; 
     $head = substr($part, 2, $endOfHead - 2); 
     $body = substr($part, $startOfBody, -2); 
     $headerParts = preg_split('#; |\r\n#', $head);

    } 
    return $return;
