[英]ASP.NET WebApi Post Method - 404 When Passing Parameters
I cannot for the life of me figure this out. 我不能为我的生活弄清楚这一点。 I have a web api controller with Get and Post methods. 我有一个带有Get和Post方法的web api控制器。 The Get method works fine with and without parameters, but the post breaks when I try to add a String parameter to it. 使用和不使用参数时,Get方法可以正常工作,但是当我尝试向其添加String参数时,帖子会中断。 Below is my code. 以下是我的代码。
Route: 路线:
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "{controller}/{id}",
defaults: new { id = UrlParameter.Optional }
);
Controller: 控制器:
public class AuditController : ApiController
{
public String Post(String test)
{
return "Success : " + test;
}
public String Get(String test)
{
return "Success : " + test;
}
}
Request: 请求:
var request = WebRequest.Create("http://localhost:42652/Audit");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
using (var writer = new StreamWriter(request.GetRequestStream()))
{
writer.Write("test=TEST");
}
WebResponse webResponse = request.GetResponse();
I've tried many variations on the request, I feel like there's something simple I'm missing. 我已经在请求上尝试了很多变化,我觉得我有一些简单的缺失。 Thanks for your help. 谢谢你的帮助。
Since you are expecting parameter test
to come from body of a request, you would need to decorate it with FromBody
attribute. 由于您希望参数test
来自请求的主体,因此您需要使用FromBody
属性来装饰它。 Example: ([FromBody]String test)
. 示例: ([FromBody]String test)
。 This is not true for other complex types, for example: Employee
class which is implicitly considered to be coming from Body. 对于其他复杂类型,情况并非如此:例如:隐式地认为来自Body的Employee
类。
Rearding GET request. 等待GET请求。 It should be working only with test coming from query string /Audit?test=Mike
它应该只适用于来自查询字符串/Audit?test=Mike
Following blog post has more details about parameter binding: http://blogs.msdn.com/b/jmstall/archive/2012/04/16/how-webapi-does-parameter-binding.aspx 以下博客文章提供了有关参数绑定的更多详细信息: http : //blogs.msdn.com/b/jmstall/archive/2012/04/16/how-webapi-does-parameter-binding.aspx
Also, I see that you are using WebRequest. 另外,我看到你正在使用WebRequest。 Have you considered using HttpClient from System.Net.Http instead? 您是否考虑过使用System.Net.Http中的HttpClient?
Change your AuditController
to include the FromBody
attribute : 更改AuditController
以包含FromBody
属性:
public class AuditController : ApiController
{
public String Post([FromBody]String test)
{
return "Success : " + test;
}
public String Get(String test)
{
return "Success : " + test;
}
}
