WebApi 后台获取token值

前台传递一个token，后台不知道怎么获取那么不是很悲剧吗。

$(function () {
    
            $.ajax({
                url: "/api/TokensTest/FirstCode",
                data: {},
                type: "Get",
                dataType: "json",
                beforeSend: function (request) {
                    request.setRequestHeader("Test", "woshiyanzhengma");
                },
                success: function (data) {
                    console.log(JSON.stringify(data));
                },
                error: function (err) {
                    alert(err);
                }
    
            });
    
        });

至于token 作用就不必说了，大家都知道，要不你也不会看到这篇文章。

重点来了。我们使用 AuthorizeAttribute 这个过滤器来处理。

public class BautA : AuthorizeAttribute
        {
             
            public override void OnAuthorization(HttpActionContext actionContext)
            {
                var authorization = actionContext.Request.Headers.Authorization;
    
    
                var content = actionContext.Request.Properties["MS_HttpContext"] as HttpContextBase;
                var token = content.Request.Headers["Test"];   //这里是拿到了token 的值 也就是  “woshiyanzhengma”

if (actionContext.ActionDescriptor.GetCustomAttributes<AllowAnonymousAttribute>(true).Count != 0 || actionContext.ActionDescriptor.ControllerDescriptor.GetCustomAttributes<AllowAnonymousAttribute>(true).Count != 0) { base.OnAuthorization(actionContext);//正确的访问方法  } } }

下面是如何使用

[BautA]
        public class TokensTestController : ApiController
        {
    
            [HttpGet]
           
            public List<Company> FirstCode()
            {
                
                
    
                List<Company> list = new List<Company> {
                    new Company{id=1,Name="探路者",Address="江苏南京",Phone="15996413689" },
                    new Company{id=2,Name="探索者",Address="江苏南京",Phone="15996413689" },
                    new Company{id=3,Name="开拓者",Address="江苏南京",Phone="15996413689" },
                    new Company{id=4,Name="探路者",Address="江苏南京",Phone="15996413689" },
                    new Company{id=5,Name="探路者",Address="江苏南京",Phone="15996413689" },
                };
                 
                return list;
            }
