Can't import a certificate via XML API using C#

L0 Member

Hello,

 

I'm trying to import a certificate to a Palo Alto VM-50 via XML API with an App written in C# but I always get this error:

 

<response status = 'error' code = '400'><result><msg>No file uploaded</msg></result></response>

 

 

My C# code is below, I can't see where the problem is, if I use this curl command the file gets uploaded successfully:

 

curl --insecure --header "Authorization:Basic myauth" -F "file=@testCA.crt" "https://10.16.66.229/api?type=import&category=certificate&certificate-name=TestCA&format=pem"

 

 

Any ideas?

 

using System;
using System.IO;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;

namespace TestUploadPA
{
    internal class Program
    {
        static async Task Main(string[] args)
        {
            string url = "https://10.16.66.229/api/?type=import&category=certificate&certificate-name=TestCA&format=pem";
            string filePath = "testCA.crt";
            string username = "myuser";
            string password = "mypass";

            var handler = new HttpClientHandler
            {
                ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => true,
            };

            using (HttpClient client = new HttpClient(handler))
            {
                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes(username + ":" + password)));

                using (var formData = new MultipartFormDataContent())
                using (var fileContent = new ByteArrayContent(File.ReadAllBytes(filePath)))
                {
                    fileContent.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
                    formData.Add(fileContent, "file", Path.GetFileName(filePath));

                    HttpResponseMessage response = await client.PostAsync(url, formData);

                    if (response.IsSuccessStatusCode)
                    {
                        string content = await response.Content.ReadAsStringAsync();
                        Console.WriteLine($"XML result: {content}");
                    }
                    else
                    {
                        Console.WriteLine($"Error uploading file. Status code: {response.StatusCode}");
                    }
                }
            }
        }
    }
}

Hello,

I managed to figured out what was wrong: the boundary in the multipart/form-data content-type header was being double quoted. I added some code to remove the quotes and I was able to import the certificate to the Palo Alto firewall successfully.
