Include content in response object Nswag client

[JanOgr]

I am currently learning about Nswag studio and have managed to generate a C# client. The generated client consumes an HTTP client and I manage to get a successful response when calling the available endpoints. However, I cannot seem to get the response body from each and every request. The only thing included in the swagger responses is the headers and the status code. Is there a way to automatically include the response content in the SwaggerResponse object or specifying what the response object should include? I.e I do not want to rewrite the generated code and check it it since I need to generate it on the fly for what I'm trying to do. I have googled for hours, tried different versions etc but cannot find what I am missing

nswag openapi2csclient /input:https://www.foodrepo.org/api-docs/swaggers/v3.json /namespace:BaseTestFrameworkCSharp.App.FoodApi /output:BaseTestFrameworkCSharp/App/FoodApi/FoodApi.cs /classname:FoodApi /usehttpclientcreationmethod:tru e /injectHttpClient:true /generateBaseUrlProperty:true /useBaseUrl:true /operationGenerationMode:SingleClientFromPathSegments /runtime:Net50 /clientClassAccessModifier:public /generateJsonMethods:true /generateDataAnnotations:true /gene rateDtoTypes:true /wrapResponses:true /generateResponseClasses:true /generateClientInterfaces:true /UseRequestAndResponseSerializationSettings:true

The generated response class looks like this, notice there is no response body only headers and status code:

    [System.CodeDom.Compiler.GeneratedCode("NSwag", "13.10.1.0 (NJsonSchema v10.3.3.0 (Newtonsoft.Json v11.0.0.0))")]
    public partial class SwaggerResponse
    {
        public int StatusCode { get; private set; }

        public System.Collections.Generic.IReadOnlyDictionary<string, System.Collections.Generic.IEnumerable<string>> Headers { get; private set; }

        public SwaggerResponse(int statusCode, System.Collections.Generic.IReadOnlyDictionary<string, System.Collections.Generic.IEnumerable<string>> headers) 
        {
            StatusCode = statusCode; 
            Headers = headers;
        }
    }

Is this functionality supported or have I missed something? If not is there a work around for generating clients on the fly based on openapi specs? @RicoSuter :D

Did you try to set ReadResponseAsString to true on the client?

[JanOgr]

Like this? Then yes.

var foodApi = new FoodApi(client) { BaseUrl = "https://www.foodrepo.org/api/v3", ReadResponseAsString = true };

[RicoSuter]

The idea is that there is also a SwaggerResponse where T is the type of the response where you can actually access the deserialized body as described by the spec.

[JanOgr]

Ok how would that look like? I Have tried a few api specs but seem to have the same problem. Eg if you would want HttpResponseMessage back.

[JanOgr]

Ok, misunderstood the response at first. So the response body needs to be specified in the spec then a class is created based on that json which is used for the T Result? And if there is no response model in the spec there is no way of just getting the plain httpresponsemessage and do the serialization on your own?

Hi, I'm facing the same problem. Not able to get the response content. I see only response code and Headers. Any suggestion would be helpful.

In below code only status and headers are returned

var response = await client.SendAsync(request, System.Net.Http.HttpCompletionOption.ResponseHeadersRead, cancellationToken).ConfigureAwait(false); var disposeResponse = true; try { var headers = System.Linq.Enumerable.ToDictionary(response.Headers, h => h.Key, h => h.Value); if (response.Content != null && response.Content.Headers != null) { foreach (var item in response.Content.Headers) headers[item.Key] = item_.Value; }

                    ProcessResponse(client_, response_);

                    var status_ = (int)response_.StatusCode;
                    if (status_ == 200)
                    {
                        return new RestResponse(status_, headers_);
                    }
                    else
                    {
                        var responseData_ = response_.Content == null ? null : await response_.Content.ReadAsStringAsync().ConfigureAwait(false);
                        throw new ApiException("The HTTP status code of the response was not expected (" + status_ + ").", status_, responseData_, headers_, null);
                    }
                }
