It is possible to PutFilesWithRequest?

[colegottdank]

I am building a PUT endpoint which takes fields as well as files. However, I see there is no 'PostFilesWithRequest' variant for PUT methods. Is there anyway around this? I want to test my fluent validation for files in this endpoint, but am unable due to not being able to upload a file.

The vast majority of HTTP File Uploads with additional Request params are done with POST so we don't want to duplicate the API surface area to support an unused method.

You can override and Simulate alternative HTTP Methods in ServiceStack with the X-Http-Method-Override HTTP Header which you can configure with your HTTP Client with:

var client = new JsonServiceClient(baseUrl) {
    RequestFilter = req => req.Headers[HttpHeaders.XHttpMethodOverride] = HttpMethods.Put
};

Alternatively you can use the SendForm/Async APIs in the new JsonApiClient (.NET 6+) to send MultipartFormDataContent requests, with something like:

using var uploadRequest = new MultipartFormDataContent()
    .AddParams(new MyRequest {
      //...
    })
    .AddFile(fieldName, fileName, fileStream);

var api = await client.SendFormAsync<MyRequestResponse>(HttpMethods.Put, typeof(MyRequest).ToApiUrl(), uploadRequest);

So, the idea is that you simulate alternative HTTP Methods and then use PostFilesWithRequest? I attempted that and received the same error about an incorrect HttpMethod which is due to the HttpMethod.Post being hardcoded into the PostFilesWithRequest method.

Yeah it should override the HTTP Method, can you provide the raw Request/Response headers (i.e. w/o request body). You can use a HTTP sniffer like Fiddler or Wireshark.

It is failing before a request is sent in the UrlExtensions.ToUrl as the hardcoded HttpMethod.Post is not matching any of my HttpMethods in my route. Do I have to accept POST requests in my route for this to work? If so, that will not work as I only want that route to be a PUT.

I've added a change that changes the PostFilesWithRequest APIs to use its preferred HTTP Method if one exists, e.g. if you only have a single route with a single verb it will use PUT otherwise you'll need to add the IPost marker interface to your Request DTO.

This change is available from v6.1.1+ that's now available on MyGet.
