I'd like to submit json from a controller in an MVC app to a Web API app.
In the Web API app, one of the controller methods takes a string:
//In ValuesController.cs
[HttpGet("{myjson}")]
public string Index (string myjson) {
...
}
If I try the url http://localhost/api/values/testing, it will go into:
[HttpGet("{id}")]
public string Get (int id) {
...
}
Which is also in ValuesController.cs.
Any ideas why the first method is not triggering?
You can build a URL that contains the properties of MyClass on the query string and invoke the remote client with HttpClient (or a third party option like RestSharp).
In addition, you need to mark your WebAPI endpoint method with [FromUri] so that it knows to expect a complex type from the query string rather than the request body.
[HttpGet("/")]
public string Index ([FromUri] MyClass aclass) {
...
}
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://.../");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var url = String.Format("api/ControllerName?ID={0}&Dept={1}",
myModel.ID, myModel.Dept);
HttpResponseMessage response = await client.GetAsync(url);
if (response.IsSuccessStatusCode)
{
MyModel model = await response.Content.ReadAsAsync<MyModel>();
}
}
In this particular case you actually don't need to create a JSON string since you can pass all of the required data on the query string. If you don't want to expose the data, you should consider changing it to a post, at which point you can post the object directly.
...
response = await client.PostAsJsonAsync(url, myModel);
...
Check out Json.NET by Newtonsoft. If you change your endpoint to accept a Stream, I think you can do something like this:
var myClass = new JsonSerializer()
.Deserialize<MyClass>(
new JsonTextReader(
new StreamReader(stream, Encoding.UTF8, false, 1, true)));
You can use a library to serialize and deserialize JSON into objects. Json.NET is pretty good at doing this.
You can use simple RestSharp client: http://restsharp.org
var client = new RestClient(" http://localhost/api/values");
var request = new RestRequest("", Method.POST);
request.RequestFormat = DataFormat.Json;
request.AddBody(new { Name = "Miroslav" });
RestResponse response = client.Execute(request);
I did not catch your controller structure, but you can update this example.

C#class instead of creating aJSONobject and then passing it to a web api that takes a c# class?
