接受Web API .Net Core中的x-www-form-urlencoded [英] Accept x-www-form-urlencoded in Web API .Net Core

问题描述

我有一个.Net Core Web API，当我尝试向其中发布包含一些json的数据时，返回415不支持的媒体错误.这是Chrome调试器返回的内容的一部分:

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

我认为这与我的控制器不接受application/x-www-form-urlencoded数据有关-但我不确定.我尝试用Consumes装饰我的控制器，但这似乎不起作用.

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..}

任何帮助，我们将不胜感激.

Any help greatly appreciated.

以下代码在.Net 4.6.1中工作正常，我能够捕获和处理上面显示的帖子.

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...

推荐答案

对于PlayerPackage，请求应发送一个 PlayerPackage Json对象，根据您的描述，您无法控制该请求从其他地方发布.

For PlayerPackage, the request should send a PlayerPackage Json Object, based on your description, you could not control the request which is posted from other place.

对于请求，其类型为 application/x-www-form-urlencoded ，它将发送带有 {"status":"incomplete"，"score":"的数据} ，而不是Json对象.如果您想接受 {"status":"incomplete"，"score":"} ，建议您像下面那样更改方法，然后通过Newtonsoft.Json将字符串转换为Object

For the request, its type is application/x-www-form-urlencoded， it will send data with {"status":"incomplete","score":""} in string Format instead of Json object. If you want to accept {"status":"incomplete","score":""}, I suggest you change the method like below, and then conver the string to Object by Newtonsoft.Json

    [HttpPost]
    [Route("~/api/trackAllInOne/set")]
    [Consumes("application/x-www-form-urlencoded")]
    public IActionResult Post([FromForm] string data)
    {
        PlayerPackage playerPackage = JsonConvert.DeserializeObject<PlayerPackage>(data);
        return Json(data);
    }
