ASP.NET Core表单POST导致HTTP 415不支持的媒体类型响应 [英] ASP.NET Core form POST results in a HTTP 415 Unsupported Media Type response
问题描述
将表单POST HTTP请求(Content-Type: application/x-www-form-urlencoded
)发送到以下控制器将导致 HTTP 415不支持的媒体类型响应.
Sending a form POST HTTP request (Content-Type: application/x-www-form-urlencoded
) to the below controller results into a HTTP 415 Unsupported Media Type response.
public class MyController : Controller
{
[HttpPost]
public async Task<IActionResult> Submit([FromBody] MyModel model)
{
//...
}
}
表单发布HTTP标头:
Form post HTTP headers:
POST /submit HTTP/1.1
Host: example.com:1337
Connection: keep-alive
Content-Length: 219
Pragma: no-cache
Cache-Control: no-cache
Origin: https://example.com:1337
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36
Content-Type: application/x-www-form-urlencoded
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Referer: https://example.com:1337/submit
Accept-Encoding: gzip, deflate, br
Accept-Language: en-US,en;q=0.8,nl;q=0.6
这曾经与.NET 4.6上的ASP.NET MVC 5一起使用.

推荐答案
对于表单,请使用 [FromForm]
属性而不是[FromBody]
属性.
For forms, use the [FromForm]
attribute instead of the [FromBody]
attribute.
以下控制器可与ASP.NET Core 1.1配合使用:
The below controller works with ASP.NET Core 1.1:
public class MyController : Controller
{
[HttpPost]
public async Task<IActionResult> Submit([FromForm] MyModel model)
{
//...
}
}
注意:如果控制器用[ApiController]
注释,则需要[FromXxx]
.对于普通视图控制器,可以将其省略.
Note: [FromXxx]
is required if your controller is annotated with [ApiController]
. For normal view controllers it can be omitted.
