Sending C# object to webapi controller
提问by neo112
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#.
我正在尝试将 C# 对象传递给 Web api 控制器。api 被配置为存储发布到它的 Product 类型的对象。我已经使用 Jquery Ajax 方法成功添加了对象，现在我正在尝试在 C# 中获得相同的结果。
I've created a simple Console application to send a Post request to the api:
我创建了一个简单的控制台应用程序来向 api 发送 Post 请求：
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 ?
postproduct 方法永远不会被调用，如何将此对象发送到控制器？
Method used for adding items:
用于添加项目的方法：
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;
}

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.
看起来您以某种方式禁止接受 JSON 作为发布格式。我能够将数据发送到您的端点并使用application/x-www-form-urlencoded. 这可能是您的 jQuery 请求正在执行的操作。
Can you show your configuration code of your web api? Do you change the default formatters?
你能显示你的 web api 的配置代码吗？您是否更改默认格式化程序？
Or you could send a form from HttpClient. e.g.
或者您可以从 HttpClient 发送表单。例如
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();
