【问题描述】：
我正在从 asp.net 学习 web.api。问题是，我的删除和放置方法现在不起作用。我认为我的代码有问题：*
这是我的删除控制器：
[ResponseType(typeof(Location))]
public IHttpActionResult DeleteLocation(Guid id)
{
Location location = _locationRepository.GetSingle(e => e.Id == id);
if (location == null)
{
return NotFound();
}
_locationRepository.Delete(location);
return Ok(location);
}
这些是我的观点：
[HttpPost]
[ResponseType(typeof(LocationViewModel))]
public async Task<IHttpActionResult> PutLocation(Guid id, LocationViewModel location)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
if (id != location.Id)
{
return BadRequest();
}
location.Id = id;
try
{
await _locationRepository.EditAsync(location.ToModel());
}
catch (DbUpdateConcurrencyException)
{
if (!LocationExist(id))
{
return NotFound();
}
else
{
throw;
}
}
return StatusCode(HttpStatusCode.NoContent);
}
这让我很困惑.. 我的获取和发布的东西完美无缺。 我正在使用邮递员来测试该方法，它说：
405 方法不允许.. 我不知道。这些是我的通用存储库。也许这也有问题..

也许这里有人可以帮助我:) 在此先感谢

可能您必须通过 web.config 或通过 owin 启用它，以允许您计划使用上述方法。还有
POST != PUT -
这对你有用吗？？
