c# - 从一个 API 调用方法已完成，但在第二个 API 上面临 Not found 错误

Question

我有两个 Wep API。我已经使用一个例如完成了 CRUD 操作。顾客。但是当我构建另一个类似的 Web API 并调用一个方法时，它显示:

{,…} Message: "No HTTP resource was found that matches the request URI http://localhost:23995/Product/Insert'."

MessageDetail: "No route providing a controller name was found to match request URI '[[same link as above here]]'"

这是我的 JS 调用方法:

$scope.Insert = function () {    

    $http({
        method: 'post',
        url: 'http://localhost:23995/Product/Insert',
        data: JSON.stringify($scope.Product)
    }).then(function (response) {
        alert("chec");

    });
}

在产品 Controller 中

// Insert 
[HttpPost]
[Route("{controller}/Insert")] 
public string Insert([FromBody] Product newProd) { 
    newProd.Insert(); 
    return newProd.DbResponse; 
} 

在供应商 Controller 中

// Insert 
[HttpPost] 
[Route("{controller}/Insert")] 
public string Insert([FromBody] Product newProd) { 
    newProd.Insert(); 
    return newProd.DbResponse; 
}

假设您已经启用了属性路由。

Attribute Routing in ASP.NET Web API 2

To enable attribute routing, call MapHttpAttributeRoutes during configuration. This extension method is defined in the System.Web.Http.HttpConfigurationExtensions class.

using System.Web.Http;

namespace WebApplication
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API routes
            config.MapHttpAttributeRoutes();

            // Other Web API configuration not shown.
        }
    }
}

并假设在给定的路线上出现错误

http://localhost:23995/Product/Insert

您的产品 Controller 应该看起来像这样。

[RoutePrefix("product")]
public class ProductController : ApiController {
    // ... other code removed for brevity

    // Insert 
    // eg: POST /product/insert
    [HttpPost]
    [Route("insert")] 
    public string Insert([FromBody] Product newProd) {...}
}

和你的供应商 Controller 看起来非常相似

[RoutePrefix("supplier")]
public class SupplierController : ApiController {
    // ... other code removed for brevity

    // Insert 
    // eg: POST /supplier/insert
    [HttpPost]
    [Route("insert")] 
    public string Insert([FromBody] Product newProd) {...}
}

你调用 JavaScript 应该能够正确调用所需的方法
