如何在基於XML的API調用中將標頭設置為“ application / x-www-form-urlencoded”

Question

我正在查看VerMail API的文檔，並且他們指定我需要將標頭設置為“ application / x-www-form-urlencoded”，但我必須以XML格式發送數據。我知道這是自動的，如果我將數據發送到數組中，但是如何使用XML？

這是我到目前為止的代碼：

$xmlcontent = "
<api>
  <authentication>
    <api_key>".$apiKey."</api_key>
    <shared_secret>".$apiSecret."</shared_secret>
    <response_type>xml</response_type>
  </authentication>

  <data>
    <methodCall>
      <methodname>legacy.message_stats</methodname>
      <last>100</last>
    </methodCall>
  </data>
</api>
";

$xmlcontent = urlencode($xmlcontent);

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "XML=".$xmlcontent);
$content = curl_exec($ch);

print_r($content);

這是我在運行源代碼時看到的：

手動添加標頭，以便您可以指定要發送並想要返回XML

您不必對XML進行URL編碼。

另外，后字段應該只是XML。 不是XML = $ xmlcontent

$xmlcontent = "
<api>
  <authentication>
    <api_key>".$apiKey."</api_key>
    <shared_secret>".$apiSecret."</shared_secret>
    <response_type>xml</response_type>
  </authentication>

  <data>
    <methodCall>
      <methodname>legacy.message_stats</methodname>
      <last>100</last>
    </methodCall>
  </data>
</api>
";

$xmlcontent = urlencode($xmlcontent);

$ch = curl_init();

$headers = array(
                "Content-type: text/xml;charset=\"utf-8\"",
                "Accept: text/xml",
                "Cache-Control: no-cache",
                "Pragma: no-cache",
                "Content-length: ".strlen($xmlcontent),
            );
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlcontent);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$content = curl_exec($ch);
