Accept x-www-form-urlencoded in Web API .Net Core

发布于 2020-03-30 21:14:11

I have a .Net Core Web API that is returning a 415 Unsupported Media Error when I try to post some data to it that includes some json. Here's part of what is returned in the Chrome Debugger:

Request URL:http://localhost:51608/api/trackAllInOne/set
Request Method:POST
Status Code:415 Unsupported Media Type
Accept:text/javascript, text/html, application/xml, text/xml, */*
Content-Type:application/x-www-form-urlencoded

action:finish
currentSco:CSharp-SSLA:__How_It_Works_SCO
data:{"status":"incomplete","score":""}
activityId:13
studentId:1
timestamp:1519864867900

I think this has to do with my controller not accepting application/x-www-form-urlencoded data - but I'm not sure. I've tried decorating my controler with Consumes but that does not seem to work.

[HttpPost]
[Route("api/trackAllInOne/set")]
[Consumes("application/x-www-form-urlencoded")]
public IActionResult Post([FromBody] PlayerPackage playerPackage)
{ etc..}

Any help greatly appreciated.

The following code worked fine in .Net 4.6.1 and I am able to capture and process the posts shown above.

[ResponseType(typeof(PlayerPackage))]
public async Task<IHttpActionResult> PostLearningRecord(PlayerPackage playerPackage)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        var id = Convert.ToInt32(playerPackage.ActivityId);
        var learningRecord = await _context.LearningRecords.FindAsync(id);
        if (learningRecord == null)
            return NotFound();
etc...

I have followed this, but my "data" is null when sending from postman. Any idea why?

@r3plica, I would use a custom type instead of string. Put data in a type itself, then next to the [FromForm], put [FromForm] CustomType request, and then in that custom type, access the data property (or other properties that are part of the form encoded request). That's what I did my case, and it works.

@firecape I am having the exact same issue, the data comes null and the former value is an string.
