Web API 2-现在允许使用方法(405)进行PUT

问题描述

我被Web API 2控制器困住了，从中我调用 PUT 方法，它给我一个错误，提示不允许使用该方法.我在 Web.config 中添加了几行代码，以防止WebDAV阻塞方法.我尝试了一切，但没有用.控制器中的 PUT 方法可能是问题.

I am stuck with Web API 2 controller, from which I call PUT method and it gives me an error that method isn't allowed. I added lines of code in Web.config that prevent WebDAV to block methods. I tried everything but it is not working. It is probably problem with my PUT method in a controller.

这是我的控制器代码:

public IHttpActionResult Put(int id, [FromBody]ArticleModel model) {
    var article = _articleService.UpdateArticle(model);
    return Ok<ArticleModel>(article);
}

这是我称之为put的代码:

This is a code from where I call put :

  response = await client.PutAsJsonAsync("api/article/2", articleModel);

在此代码之前，我将客户端定义为http并添加了所需的属性，并调用了其他控制器方法(GET，POST，DELETE)，它们都可以工作.这是从Windows Form应用程序发出的，我也从Postman打电话，但仍然是相同的错误.

before this code I defined client as http and added needed properties, and called other controller methods (GET, POST, DELETE) , they all work. This is from Windows Form app, and I am also calling from Postman but still the same error.

推荐答案

添加 [HttpPut] ， [RoutePrefix("api/yourcontroller")] 和[Route("put")] 属性分配给您的控制器方法

Add [HttpPut] , [RoutePrefix("api/yourcontroller")] and [Route("put")] attribute to your controller method

示例:

[RoutePrefix("api/yourcontroller")]
public class YourController
{
 [HttpPut]
 [Route("{id}/put")]
 public IHttpActionResult Put(int id, [FromBody]ArticleModel model) {
   var article = _articleService.UpdateArticle(model);
   return Ok<ArticleModel>(article);
 }
}

编辑1

public class YourController
{
 [HttpPut]
 [Route("api/article/{id}/put")]
 public async Task<HttpResponseMessage> Put(int id, [FromBody]ArticleModel model) {
   var article = _articleService.UpdateArticle(model);
   return Ok<ArticleModel>(article);
 }
}

从您的HttpRequest调用看来，似乎应该是 HttpResponseMessage ，因此将返回类型更改为 async Task< HttpResponseMessage>

From your HttpRequest call It seems what is expected is a HttpResponseMessage So changed the return type to async Task<HttpResponseMessage>

用于创建HttpRequest的代码:

Code for making HttpRequest:

response = await client.PutAsJsonAsync("api/article/2/put", articleModel);
