Passing complex parameters to a GET Action

Question

I need to pass parameters for filtering to ASP.NET Core REST API Server using HttpClient.

Filter contains complex data type. I used to pass data by HttpPost, but it not suitable for CRUD concept.

How can I send complex data type as json object in HttpGet request?

Answer 1

You can do it by defining your own Get method e.g.:

static async Task<HttpResponseMessage> GetAsync(this HttpClient client, string uri, HttpContent content, CancellationToken cancelToken)
{
    var request = new HttpRequestMessage(new HttpMethod("GET"), uri)
    {
        Content = content
    };
    return await client.SendAsync(request, cancelToken);
}

However! It is not recommended to do so, read about it here: HTTP GET with request body

The better solution would be to convert your complex object into URL parameters
