我有一個類,名字是廣告:沒有MediaTypeFormatter可讀取類型的對象「廣告」在asp.net網頁API
public class Advertisement
{
public string Title { get; set; }
public string Desc { get; set; }
}
,並在我的控制器:
public class OrderController : ApiController
{
public UserManager<IdentityUser> UserManager { get; private set; }
// Post api/Order/Test
[Route("Test")]
public IHttpActionResult Test(Advertisement advertisement)
{
var currentUser = User.Identity.GetUserId();
Task<IdentityUser> user = UserManager.FindByIdAsync(currentUser);
return Ok(User.Identity.GetUserId());
}
但是當我用郵差測試它時,我面對這個錯誤,
"Message": "The request contains an entity body but no Content-Type header. The inferred media type 'application/octet-stream' is not supported for this resource.",
"ExceptionMessage": "No MediaTypeFormatter is available to read an object of type 'Advertisement' from content with media type 'application/octet-stream'.",
"ExceptionType": "System.Net.Http.UnsupportedMediaTypeException",
"StackTrace": " at System.Net.Http.HttpContentExtensions.ReadAsAsync[T](HttpContent content, Type type, IEnumerable`1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)\r\n at System.Net.Http.HttpContentExtensions.ReadAsAsync(HttpContent content, Type type, IEnumerable`1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)\r\n at System.Web.Http.ModelBinding.FormatterParameterBinding.ReadContentAsync(HttpRequestMessage request, Type type, IEnumerable`1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)"
Can AnyBody能幫助我嗎?
內部從我出現的錯誤,你有沒有Content-Type頭?在Postman調用中添加適當的頭文件Content-Type,並且應該修復它。 –
我有'Content-Type'和'Accept'在我的頭文件中@DaveAgaba –
請查看下面的答案。 –
