WebAPI的AuthorizeAttribute扩展类中获取POST提交的数据

在WEBAPI中，AuthorizeAttribute类重写时，如何获取post数据是个难题，网上找资料也不好使，只能自己研究，通过研究发现，WEBAPI给了我们获取POST数据的可能，下面介绍一下：

//将POST数据以字符串的形式读取，例如post的json数据，就可以以这种方式读取
actionContext.Request.Content.ReadAsStringAsync();

---

actionContext.Request.Content.ReadAsStreamAsync();

---

actionContext.Request.Content.ReadAsFormDataAsync();

代码具体如下：

 1 using System;  2 using System.Collections.Generic;  3 using System.Linq;  4 using System.Net.Http;  5 using System.Web;  6 using System.Web.Http;  7 using System.Web.Http.Controllers;  8 using BoxSecurity;  9  10 namespace BoxWebApiFilter 11 { 12     [AttributeUsage(AttributeTargets.Interface | AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)] 13     public class ApiAuthorizeFilter : AuthorizeAttribute 14     { 15         private static List<string> PublicCmds = new List<string>() 16         { 17             "XXXX" 18         }; 19         protected override bool IsAuthorized(HttpActionContext actionContext) 20         { 21             // 验证token 22             //var token = actionContext.Request.Headers.Authorization; 23             var ts = actionContext.Request.Headers.Where(c => c.Key.ToLower() == "tokenxxx").FirstOrDefault().Value; 24             var requestContent = actionContext.Request.Content.ReadAsStringAsync();//读取post提交的json数据 25             requestContent.Wait();//等待异步读取结束 26             var inputJson = requestContent.Result; 27             //此接口无需token验证 28             BoxCommand.CmdRequest request = 29                 Newtonsoft.Json.JsonConvert.DeserializeObject<BoxCommand.CmdRequest>(inputJson); 30             if (PublicCmds.Contains(request.Cmd)) 31             { 32                 return true; 33             } 34  35             if (ts != null && ts.Count() > 0) 36             { 37                 var token = ts.First<string>(); 38                 // 验证token 39                 return TokenHelper.IsExistToken(token); 40             } 41  42             if (actionContext.Request.Method == HttpMethod.Options) 43                 return true; 44             return false; 45  46         } 47     } 48 }
