Unhandled exception. System.Net.Http.HttpRequestException: 405 - Method Not Allowed

Hi, I'm getting the below error using the Nuget package while running an IPFS node locally.

$ dotnet run
Unhandled exception. System.Net.Http.HttpRequestException: 405 - Method Not Allowed

at Ipfs.Http.IpfsClient.ThrowOnErrorAsync(HttpResponseMessage response)
at Ipfs.Http.IpfsClient.DownloadAsync(String command, CancellationToken cancel, String arg, String[] options)

I'm using your sample code as per instructions on the readme page

using Ipfs.Http;

var ipfs = new IpfsClient();

const string filename = "QmXarR6rgkQ2fDSHjSY5nM2kuCXKYGViky5nohtwgF65Ec/about";
string text = await ipfs.FileSystem.ReadAllTextAsync(filename);

Problem is caused by a breaking change in the HTTP interface of the IPFS daemon. Since version 0.5.0, all the endpoints accept only POST requests.

And this is my temp solution for this issue - override default methods using PostDownloadAsync instead of DownloadAsync (certainly not the best choice, but still works for me) 😅

public class CustomIpfsFileReader
{
	private readonly IpfsClient ipfs;

	internal CustomIpfsFileReader(IpfsClient ipfs)
	{
		this.ipfs = ipfs;
	}

	public async Task<string> ReadAllTextAsync(string path, CancellationToken cancel = default)
	{
		await using Stream data = await this.ReadFileAsync(path, cancel);
			using StreamReader reader = new StreamReader(data);
			return await reader.ReadToEndAsync();
	}

	public Task<Stream> ReadFileAsync(string path, CancellationToken cancel = default)
	{
		return this.ipfs.PostDownloadAsync("cat", cancel, path);
	}

	public Task<Stream> ReadFileAsync(string path, long offset, long length = 0, CancellationToken cancel = default)
	{
		return this.ipfs.PostDownloadAsync("cat", cancel, path, $"offset={offset}", $"length={length}");
	}

	public Task<IFileSystemNode> ListFileAsync(string path, CancellationToken cancel = default)
	{
		return this.ipfs.FileSystem.ListFileAsync(path, cancel);
	}

	public Task<Stream> GetAsync(string path, bool compress = false, CancellationToken cancel = default)
	{
		return this.ipfs.FileSystem.GetAsync(path, compress, cancel);
	}
}

That helped. Thanks
