问题描述
我必须在XML中调用使用EPP(可扩展供应协议)的Web API并返回XML作为响应。我还需要使用证书来调用它,但收到的响应为空。 PHP中只有一个示例代码可用。
eppClient.php
I have to call a web API in XML that use EPP (Extensible Provisioning Protocol) and returns a XML as response. I also need to use a certificate to call it, but the received response is null. There is only a sample code in PHP that works.
eppClient.php
<?php
require_once 'config.php';
require_once 'eppFunctions.php';
//Get XML variable via POST method
$xmlStr = stripslashes(trim($_POST['xmlStr']));
$response = send_epp_request($USER_CERTIFICATE_FILE, $EPP_SERVER_URL, $xmlStr);
if(!$response === false){
//Show Server Response as XML
header("Content-type: application/xml");
echo $response;
}
?>
config。 php
config.php
<?php
//Server URL Address For Sending XML
$EPP_SERVER_URL = "api.site.com/submit";
//URL CERTIFICATE FILE
$USER_CERTIFICATE_FILE = "";
?>
eppFunctions.php
eppFunctions.php
<?php
function send_epp_request_form($USER_CERTIFICATE_FILE, $EPP_SERVER_URL, $xmlStr)
{
$XML = array('xmlStr' => $xmlStr);
// create a new cURL resource
$ch = curl_init();
//FALSE to stop cURL from verifying the peer's certificate
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
//The name of a file containing a PEM formatted certificate.
curl_setopt($ch, CURLOPT_SSLCERT, $USER_CERTIFICATE_FILE);
//TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
//The contents of the "User-Agent: "
curl_setopt($ch, CURLOPT_USERAGENT, "IRNIC_EPP_Client_Sample");
//The URL to fetch.
curl_setopt($ch, CURLOPT_URL,"https://$EPP_SERVER_URL");
//TRUE to do a regular HTTP POST.
curl_setopt($ch, CURLOPT_POST, 1);
//The full data to post in a HTTP "POST" operation.
curl_setopt($ch, CURLOPT_POSTFIELDS, $XML);
// grab URL and pass it to the browser
$response = curl_exec($ch);
if($response === false) {
// echo Errors
echo 'Curl error: ' . curl_error($ch);
}
// close cURL resource, and free up system resources
curl_close ($ch);
return $response;
}
function send_epp_request($USER_CERTIFICATE_FILE, $EPP_SERVER_URL, $xmlStr)
{
// create a new cURL resource
$ch = curl_init();
//FALSE to stop cURL from verifying the peer's certificate
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
//The name of a file containing a PEM formatted certificate.
curl_setopt($ch, CURLOPT_SSLCERT, $USER_CERTIFICATE_FILE);
//TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
//The contents of the "User-Agent: "
curl_setopt($ch, CURLOPT_USERAGENT, "IRNIC_EPP_Client_Sample");
//TRUE to do a regular HTTP POST.This POST is the normal application/x-www-form-urlencoded kind, most commonly used by HTML forms.
curl_setopt($ch, CURLOPT_POST, false);
//The URL to fetch.
curl_setopt($ch, CURLOPT_URL,"https://$EPP_SERVER_URL");
//The full data to post in a HTTP "POST" operation.
curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlStr);
// grab URL and pass it to the browser
$response = curl_exec($ch);
if($response === false) {
// echo Errors
echo 'Curl error: ' . curl_error($ch);
}
// close cURL resource, and free up system resources
curl_close ($ch);
return $response;
}
?>
我尝试了什么:
我尝试了几种方式,如WebClient,HttpWebRequest或HttpClient,但所有方法都没有结果。
What I have tried:
I tried several ways like WebClient, HttpWebRequest or HttpClient, but all of them have no result.
protected string WebApiCall (string Data, string Url)
{
//Url in https
byte[] BytesOfData = Encoding.ASCII.GetBytes(Data);
string CertFile = Server.MapPath("~/crt/abc.p12");
string CertKey = "abc";
string ResponseData = string.Empty;
//ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
//ServicePointManager.ServerCertificateValidationCallback = (a, b, c, d) => true;
ServicePointManager.Expect100Continue = true;
X509Certificate2Collection SrvCertificate = new X509Certificate2Collection();
SrvCertificate.Import(CertFile, CertKey, X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet);
//X509Certificate2 SrvCertificate = new X509Certificate2(CertFile, CertKey);
HttpWebRequest HttpWebRequest = (HttpWebRequest)WebRequest.Create(Url);
HttpWebRequest.ClientCertificates = SrvCertificate;
//HttpWebRequest.ClientCertificates.Add(SrvCertificate);
HttpWebRequest.Method = "POST";
HttpWebRequest.Accept = "application/xml";
HttpWebRequest.ContentType = "application/xml";
HttpWebRequest.ContentLength = BytesOfData.Length;
Stream RequestStream = HttpWebRequest.GetRequestStream();
RequestStream.Write(BytesOfData, 0, BytesOfData.Length);
RequestStream.Close();
HttpWebResponse HttpWebResponse = (HttpWebResponse)HttpWebRequest.GetResponse();
if (HttpWebResponse.StatusCode == HttpStatusCode.OK)
{
Stream ResponseStream = HttpWebResponse.GetResponseStream();
ResponseData += new StreamReader(ResponseStream).ReadToEnd();
return ResponseData;
}
return null;
}
推荐答案
xmlStr = stripslashes(trim(
xmlStr = stripslashes(trim(
_POST [' xmlStr']));
_POST['xmlStr']));
response = send_epp_request(
response = send_epp_request(
