reading Json and Xml

Question

I am running this code and it works great ..except when I am reading the xml. it reads the json but not the xml.

I was following the directions in this post Combine XML And Json Requests And Responses In ASP.NET Core Web API .

I am trying to give the user the function to send data in either json or xml.

I don't know how to get it to also read the xml in the post function or what I did wrong

here is my code

[[Route("api/[controller]")]
    public class CancelController : Controller
    {
        [HttpGet("get.{format}"), FormatFilter]
        public IEnumerable<BatchData> Get()
        {
            List<BatchData> cancel = new List<BatchData>
                {
                    new BatchData { BatchNumber = "1"},
                    new BatchData { BatchNumber = "2"}
                };
            return cancel;
        }

        [HttpPost("post.{format}"), FormatFilter]
        public BatchData Post([FromBody] BatchData cancel)
        {
            if (ModelState.IsValid)
            {
                return cancel;
            }
            else
            {
                return cancel;
            }
        }
    ]

hi, You can trying by adding this as well public IServiceProvider ConfigureServices(IServiceCollection services) { services.AddMvc(); services.ConfigureMvc( options = > { // This adds both Input and Output formatters based on DataContractSerializer options.AddXmlDataContractSerializerFormatter(); // To add XmlSerializer based Input and Output formatters. options.InputFormatters.Add(new XmlSerializerInputFormatter()); options.OutputFormatters.Add(new XmlSerializerOutputFormatter()); });

Hi, You can resolve by these steps: 1. add Microsoft.AspNetCore.Mvc.Formatters.Xml package from nuget 2. Add in configurationservice public void ConfigureServices(IServiceCollection services) { services.AddMvc() .AddXmlSerializerFormatters(); } Alternatively, if the issue persist public void ConfigureServices(IServiceCollection services) { services.AddMvc( options = > { options.FormatterMappings.SetMediaTypeMappingForFormat ("xml", MediaTypeHeaderValue.Parse("application/xml")); options.FormatterMappings.SetMediaTypeMappingForFormat ("config", MediaTypeHeaderValue.Parse("application/xml")); options.FormatterMappings.SetMediaTypeMappingForFormat ("js", MediaTypeHeaderValue.Parse("application/json")); }) .AddXmlSerializerFormatters(); Try this to resolve.

Hi, Please skip step 2, if you are goind for alternative. Addtionally, add this in post method in controller [Consumes("application/xml")] [HttpPost("post.{format}"), FormatFilter] public BatchData Post([FromBody] BatchData cancel) { Can you try this way?

I had the first 2 steps already and the third also didn't work. so I have this code also and agian the only thing that doesn't work is the xml string being submited and the line public batchdata post([frombody] batchData Batch is null only when I send xml 431864 4/13/2021 12:15:25 PM DEMO jgalt using Microsoft.AspNetCore.Mvc; using System.Collections.Generic; namespace GaltBatchWebService.Controllers { [Route( "api/[controller]" )] public class BatchController : Controller { [HttpGet( "get.{format}" ), FormatFilter] public IEnumerable Get() { List batch = new List { new BatchData { BatchNumber = "1" , DateProcessed = "Sarath Lal" ,DealerNumber= "Cochin" ,MemberUsername = "MyName" }, new BatchData { BatchNumber = "2" , DateProcessed = "Anil Kumar" ,DealerNumber= "Bangalore" ,MemberUsername = "myName" } }; return batch; } [HttpPost( "post.{format}" ), FormatFilter] public BatchData Post([FromBody] BatchData batch) { if (ModelState.IsValid) { return batch; } else { return null ; } } } }
