根据要求使用RestSharp添加证书 [英] Add certificate on request with RestSharp

问题描述

我正在尝试与服务器通信。该服务器向我发送了证书和私钥，以便成功执行我的请求。

要测试服务器，请使用

现在我想在C＃中做同样的事情。

为此，我使用 RestSharp 即可创建请求。

这是我的代码

  var client = new RestClient（url ）; 
 
 byte [] certBuffer = UtilsService.GetBytesFromPEM（myCertificate，Models.Enum.PemStringType.Certificate）; 
 byte [] keyBuffer = UtilsService.GetBytesFromPEM（encryptedPrivateKey，Models.Enum.PemStringType.RsaPrivateKey）; 
 
 X509Certificate2证书=新的X509Certificate2（certBuffer，secret）; 
 client.ClientCertificates = new X509CertificateCollection（）{certificate}; 
 var request = new RestRequest（Method.POST）; 
 request.AddHeader（ Cache-Control， no-cache）; 
 request.AddHeader（ Accept， application / json）; 
 request.AddHeader（ Content-Type， application / json）; 
 request.AddParameter（ myStuff，ParameterType.RequestBody）; 
 IRestResponse响应= client.Execute（请求）; 
  

该请求无效。我认为问题出在我如何在RestSharp中加载证书。

我正在寻找有关如何在RestSharp中正确设置证书的信息。

我正在使用RestSharp ，但我可以是其他任何可以在C＃中工作的东西。

解决方案

好，我得到了解决方案。

首先，我必须停止使用.crt和.key作为证书。我必须得到一个.pfx。可以使用openssl命令（ openssl文档）完成 p>

  openssl pkcs12-导出-out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt 
  

创建证书后，只需将其添加到请求中即可

  var client = new RestClient（url）; 
 
 ServicePointManager.Expect100Continue = true; 
 ServicePointManager.DefaultConnectionLimit = 9999; 
 ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3; 
 
 var certFile = Path.Combine（certificateFolder， certificate.pfx）; 
 X509Certificate2证书=新的X509Certificate2（certFile，onboard.authentication.secret）; 
 client.ClientCertificates = new X509CertificateCollection（）{certificate}; 
 client.Proxy = new WebProxy（）; 
 var restrequest = new RestRequest（Method.POST）; 
 restrequest.AddHeader（ Cache-Control， no-cache）; 
 restrequest.AddHeader（ Accept， application / json）; 
 restrequest.AddHeader（ Content-Type， application / json）; 
 restrequest.AddParameter（ myStuff，ParameterType.RequestBody）; 
 IRestResponse响应= client.Execute（restrequest）; 
  

I'm trying to communicate with a server. This server send me a certificate and a private key in order to execute my request successfully.

To test the server, I use Postman. So I fill the certificate setting in postman, and my request works fine

Now I want to do the same in C#.

For that I use RestSharp in order to create the request.

Here is my code

 var client = new RestClient(url);

 byte[] certBuffer = UtilsService.GetBytesFromPEM(myCertificate, Models.Enum.PemStringType.Certificate);
 byte[] keyBuffer = UtilsService.GetBytesFromPEM(encryptedPrivateKey, Models.Enum.PemStringType.RsaPrivateKey);

 X509Certificate2 certificate = new X509Certificate2(certBuffer, secret);
 client.ClientCertificates = new X509CertificateCollection() { certificate };
 var request = new RestRequest(Method.POST);
 request.AddHeader("Cache-Control", "no-cache");
 request.AddHeader("Accept", "application/json");
 request.AddHeader("Content-Type", "application/json");
 request.AddParameter("myStuff", ParameterType.RequestBody);
 IRestResponse response = client.Execute(request);

The request doesn't work. I think the problem is from how I load the certificate in RestSharp.

I'm looking for information how to set correctly the certificate in RestSharp.

I'm using RestSharp, but I could be anything else that can work in C#

解决方案

Ok, I got the solution.

First of all, I had to stop using the .crt and the .key for the certificate. I have to get a .pfx. This can be done with openssl command (openssl documentation)

openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt

After creating the certificate, just add it to the request like this

var client = new RestClient(url);

ServicePointManager.Expect100Continue = true;
ServicePointManager.DefaultConnectionLimit = 9999;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3;

var certFile = Path.Combine(certificateFolder, "certificate.pfx");
X509Certificate2 certificate = new X509Certificate2(certFile, onboard.authentication.secret);
client.ClientCertificates = new X509CertificateCollection() { certificate };
client.Proxy = new WebProxy();
var restrequest = new RestRequest(Method.POST);
restrequest.AddHeader("Cache-Control", "no-cache");
restrequest.AddHeader("Accept", "application/json");
restrequest.AddHeader("Content-Type", "application/json");
restrequest.AddParameter("myStuff", ParameterType.RequestBody);
IRestResponse response = client.Execute(restrequest);
