Question

我使用角度js请求放置到Web API，但我得到了404响应。虽然上下班很棒。可能是什么原因。我瞪着眼睛，人们在谈论webdev我几乎所有的东西都是愚蠢的404。

请求者和API都位于同一个域http://locathost/api和http://localhost/app

服务器端代码

  // PUT: api/Projects/5
    [ResponseType(typeof(void))]
    public async Task<IHttpActionResult> PutProject(int id, Project project)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        if (id != project.Id)
        {
            return BadRequest();
        }

        db.Entry(project).State = EntityState.Modified;

        try
        {
            await db.SaveChangesAsync();
        }
        catch (DbUpdateConcurrencyException)
        {
            if (!ProjectExists(id))
            {
                return NotFound();
            }
            else
            {
                throw;
            }
        }

        return StatusCode(HttpStatusCode.NoContent);
    }

AngularJs服务

mediaApp.factory('Api', function ($resource) {
var data = $resource('http://localhost/api/projects/:id', {id: '@id'}, {
    update:{
        method:'PUT'
    }
});
return data;

}）;

angularjs控制器调用它

  Api.update({ id: 9}, {id:9,projectName: 'test', number: 'test', dateTime: 'test', inspector: 'test', neighborhood: 'test', field1: 'test', field2: 'test' });

和我得到的错误

看一下这两篇文章

如果此帖子无法访问，您需要检查IIS处理程序映射以确保所有动词都允许使用模块：

ExtensionlessUrlHandler-ISAPI-4.0_32bit
ExtensionlessUrlHandler-ISAPI-4.0_64bit
ExtensionlessUrlHandler集成-4.0

Web API PUT返回404
