发送C＃对象的WebAPI控制器 [英] Sending C# object to webapi controller

问题描述

我想一个C＃对象传递到Web API控制器。 API被配置为存储投递到这类型的产品对象。我使用Jquery的Ajax方法成功添加的对象，现在我试图让在C＃中相同的结果。

我创建了一个简单的控制台应用程序发送POST请求的API：

 公共类产品
{
    公众诠释标识{搞定;组; }
    公共字符串名称{;组; }
    公共字符串类别{搞定;组; }
    公共十进制价格{搞定;组; }
}         静态无效的主要（字串[] args）
    {
        字符串apiUrl = @的http：//本地主机：3393 / API /产品;
        VAR的客户=新的HttpClient（）;
        client.PostAsJsonAsync＆LT;产品及GT;（apiUrl，新产品（）{ID = 2，名称=牛仔裤，价格= 200，类别=服装}）;    }
 

该postproduct方法是永远不会调用，如何将这些对象发送到控制器？

用于添加物品的方法：

 公开的Htt presponseMessage PostProduct（[FromBody]产品项）
    {
        项目= repository.Add（项目）;
        VAR响应= Request.CreateResponse＆LT;产品及GT;（的HTTPStatus code.Created，项目）;        字符串URI = Url.Link（DefaultApi，新{ID = item.Id}）;
        response.Headers.Location =新的URI（URI）;
        返回响应;
    }
 

解决方案

看起来你已经以某种方式禁用接受JSON作为发布格式。我能够将数据发送到您的端点和使用创造新产品应用程序/ x-WWW的形式urlen codeD 。这可能是你的jQuery请求是怎么做的吧。

您可以显示你的网页API的配置code？你更改默认格式化？

或者你可以从HttpClient的发送形式。例如。

 字符串apiUrl =htt​​p://producttestapi.azurewebsites.net/api/products;
    VAR的客户=新的HttpClient（）;
    VAR值=新词典＆LT;字符串，字符串＆GT;（）
        {
            {ID，6}，
            {姓名，滑雪}，
            {价格，100}，
            {类别，体育}
        };
    VAR内容=新FormUrlEn codedContent（值）;    VAR响应=等待client.PostAsync（apiUrl，内容）;
    response.EnsureSuccessStatus code（）;
 

I'm trying to pass a C# object to a web api controller. The api is configured to store objects of type Product that are posted to it. I have successfully added objects using Jquery Ajax method and now I'm trying to get the same result in C#.

I've created a simple Console application to send a Post request to the api:

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Category { get; set; }
    public decimal Price { get; set; }
}

         static void Main(string[] args)
    {
        string apiUrl = @"http://localhost:3393/api/products";
        var client = new HttpClient();
        client.PostAsJsonAsync<Product>(apiUrl, new Product() { Id = 2, Name = "Jeans", Price = 200, Category =  "Clothing" });

    }

The postproduct method is never invoked, how to send this object to the controller ?

Method used for adding items:

    public HttpResponseMessage PostProduct([FromBody]Product item)
    {
        item = repository.Add(item);
        var response = Request.CreateResponse<Product>(HttpStatusCode.Created, item);

        string uri = Url.Link("DefaultApi", new { id = item.Id });
        response.Headers.Location = new Uri(uri);
        return response;
    }

解决方案

Looks like you have somehow disabled accepting JSON as format for posting. I was able to send the data to your endpoint and create new product using application/x-www-form-urlencoded. That is probably how your jQuery request is doing it.

Can you show your configuration code of your web api? Do you change the default formatters?

Or you could send a form from HttpClient. e.g.

    string apiUrl = "http://producttestapi.azurewebsites.net/api/products";
    var client = new HttpClient();
    var values = new Dictionary<string, string>()
        {
            {"Id", "6"},
            {"Name", "Skis"},
            {"Price", "100"},
            {"Category", "Sports"}
        };
    var content = new FormUrlEncodedContent(values);

    var response = await client.PostAsync(apiUrl, content);
    response.EnsureSuccessStatusCode();
