Question

我是角度js和webapi的新手

问题：

我无法使用json url发布数据：＆＃34; NewRoute / firstCall＆＃34;从视图到WebAPI控制器

但我可以使用网址发布：＆＃34; http://localhost:2730/NewRoute/firstCall＆＃34;，

的情况下发布数据

事情是我在一个解决方案中有两个项目。 1.AngularJS 2.WebAPI

在视图中

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <script src="Scripts/angular.js"></script>
        <script>     
            var TestCtrl = function ($scope, $http) {
                $scope.SendData = function (Data) {
                    var GetAll = new Object();
                    GetAll.txt1 = Data.txt1;
                    $http({
                        url: "NewRoute/firstCall",
                        //url: "http://localhost:2730/NewRoute/firstCall",
                        dataType: 'json',
                        method: 'POST',
                        data: GetAll,
                        headers: {
                            "Content-Type": "application/json"
                        }
                    }).success(function (response) {
                        $scope.value = response;
                    })
                    .error(function (error) {
                        alert(error);
                    });
                }
            };
            var myApp = angular.module("myApp", []);
            myApp.controller("TestCtrl", TestCtrl);
        </script>
    </head>
    <body ng-app="myApp">
        <div ng-controller="TestCtrl">
            <hr />
            <div>
                Enter text
                <input type="text" placeholder="Enter your name" ng-model="details.txt1">
            </div>
            <hr />
            <input type="button" ng-click="SendData(details)" value="Submit" />
            <hr />
            <h4 style="color:blueviolet">{{value}}</h4>
        </div>
        <hr />
    </body>
</html>

在Web Api控制器中

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
namespace WebApplication1.Controllers
{
    [RoutePrefix("NewRoute")]
    public class NewController : ApiController
    {
        public class GetAll
        {
            public string txt1 { get; set; }
        }
        [Route("firstCall")]
        [HttpPost]
        public string firstCall(HttpRequestMessage request,
            [FromBody] GetAll getAll)
        {
            return "Success";
        }
    }
}

WebApi提供商

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;

namespace WebApplication1
{
    public class WebApiApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }
        protected void Application_BeginRequest()
        {
            if (Request.Headers.AllKeys.Contains("Origin")
                && Request.HttpMethod == "OPTIONS")
            {
                Response.Flush();
            }
        }
    }
}

Answer 1

这可能是问题的相对网址，因为当你有一个完整的网址时，它会正常工作。

试试这个：

   $http({
        url: "/NewRoute/firstCall",
        dataType: 'json',
        method: 'POST',
        data: GetAll,
        headers: {
            "Content-Type": "application/json"
        }
    }).success(function (response) {
        $scope.value = response;
    })
    .error(function (error) {
        alert(error);
    });

请注意网址前面的前导/。这将导致浏览器使用网址currentdomain.org/NewRoute/firstCall

发出请求

将数据从angularjs客户端发布到WEBAPI控制器
