Why HttpPost isn't working in WebApi

I am making an ajax request from the clientside to my web service built in web api.

Here is the client side code :

$.ajax({

url: "http://localhost:1583/api/storage/processing/v1/preview/test.docx",

type: "POST",

contentType: "application/json; charset=utf-8",

dataType: "json",

cache: false,

responseType: "json",

beforeSend: onProgress,

success: GenerateHtml,

complete: onComplete,

error: onFail

});

Here is the controller's code:

[HttpPost]

[Route(WebApiConfig.RootApiUri + "/v1/preview/{docid}")]

public async Task> Preview(string docid)

{

///...ommitted the code..///

}

HttpPost isn't working, however if change it to HttpGet it works.

Any help on this would be greatly appreciated. Thanks.

@Bhuvanesh : your suggestion was helpful. I did a few tweaks removed {docid} from the route. Added [FromBody] in Preview([FromBody] string docid), changed the url in ajax code to http://localhost:1583/api/storage/processing/v1/previewand added data: JSON.stringify("test.docx")
It works now.

If you are passing a JSON object, your WEB API method should receive the parameter, however here in the sample you have only string object as parameter.
public async Task> Preview(string docid)
Sample:
public bool SaveContact(Contact contact)
publicboolSaveContact(Contactcontact)

@pritaeas:
[AllowAnonymous], is concern only during Authentication /Authorization issue,
Hereif the issue with Authentication, then the "GET" also may not worked andunauthorized error may occurred.

Have you tried what happens if you remove the routing?
I usually also test using SoapUI, it sometimes shows better errors than trying yourself with Javascript.

@bhuvanesh: I intend to send a json object from the ajax post request and convert the data into an object in the service hence I want to have POST request only.

@pritaeas : controller has [AllowAnonymous] attribute and both client side code and server side code are in the same project.

GET - Requests data from a specified resource
POST - Submits data to be processed to a specified resource
Here you are passing only a file name, which can be send through the URL itself, so better suggested is the Get method.
When you send a application model to the web api, then post is advisable.
Mark as answer, if helpful.

If you add
[AllowAnonymous]
does it work then?
