无法从 Web 应用程序中找到 Web API 方法

Question

这是web应用程序中的启动破坏控制器方法：

public ActionResult PaginationOfBooks(string _title, string _author, string _description, string _publisher)
        {

            HttpClient client = new HttpClient();
            client.BaseAddress = new Uri("http://localhost:57752");
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            HttpResponseMessage response = client.GetAsync("api/Book/GetBooks").Result;

休息还不重要。实际上此时，在调试模式下，我希望在与 Web 应用程序相同的解决方案中切换 WebApi 项目，GetBooks 方法我在此方法的第一行有断点。这是结果的内容：

StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

我的网络 abi 项目：

public ActionResult GetBooks(string _title, string _author, string _description, string _publisher)
        {
            var draw = 1;
...

webapi 配置：

public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services

            // Web API routes
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/Book/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            config.Formatters.Remove(config.Formatters.XmlFormatter);
            config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/json"));
        }
    }

我怎样才能得到这个 web api 请求？

我运行 api 项目并尝试使用以下方法访问方法：

Answer 1

像这样更改您的 WebApiConfig-

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );

    config.Routes.MapHttpRoute(
        name: "BooksApi",
        routeTemplate: "api/{controller}/{email}/{firstname}/{lastname}/{source}"
    );

然后像这样从 PaginationOfBooks 调用-

HttpResponseMessage response = client.GetAsync("api/Book/GetBooks/" + _title + "/" + _author + "/" + _description + "/" + _publisher).Result;

看看这是否有帮助。

Answer 2

在api方法前添加路由属性

[Route("api/Book/GetBooks/{_title}/{_author}/{_description}/{_publisher}")]
public ActionResult GetBooks(string _title, string _author, string _description, string _publisher)
        {
            var draw = 1;
...

然后称它为

public ActionResult PaginationOfBooks(string _title, string _author, string _description, string _publisher)
        {

            HttpClient client = new HttpClient();
            client.BaseAddress = new Uri("http://localhost:57752");
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            HttpResponseMessage response = client.GetAsync("api/Book/GetBooks/" + _title + "/" + _author + "/" + _description + "/" + _publisher).Result;
