我有两个项目的客户端和服务器端。客户方项目是纯粹的htmljs。服务器端是ASP.NET MVC 4和Web API。因为有两个项目，我需要启用CROS功能。我加入到服务器的 webconfig

I have two projects client side and server side. Client side project is pure htmljs. Server side is ASP.NET MVC 4 and Web Api. Because there are two projects I need to enable CROS functionality. I added into server's webconfig:

<system.webServer>
 <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Headers" value="Content-Type" />
      </customHeaders>
    </httpProtocol>
</system.webServer>

阿贾克斯后的版本这是工作：

$.post(url, appContext).done(
                function(data, textStatus, jqXHR) {
                    successFn(data, textStatus);
                })
                .fail(
                    function(jqXHR, textStatus, err) {
                        errorFn(err, textStatus);
                    });

角$ HTTP POST版本，这是不工作：

 $http({
                url: url,
                method: 'POST',
                params: { appContext: appContext },
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded'
                    /*'Accept': 'text/json'*/}
            }).success(successFn).error(errorFn);

当我使用的$ HTTP我得到两个错误：

When I use $http I am getting two errors:

ASP.NET MVC方法

ASP.NET MVC method is

[System.Web.Http.HttpPost]
public List<Module> GetModules([FromBody]SessionContext appContext)
{
 return  CreateModules();
}

编辑：

角车型的配置：

var emsApp = angular.module('EmsWeb', ['ui.bootstrap']);
emsApp.config(['$routeProvider', '$httpProvider', function($routeProvider, $httpProvider) {

    $httpProvider.defaults.useXDomain = true;
    delete $httpProvider.defaults.headers.common['X-Requested-With'];
}]);

选项的标题要求我在浏览器中看到：

Request URL:http://localhost/EmsWeb/api/ModuleApi/GetModules?appContext=%7B%22globalDate%22%3A%22Mon%2C%2008%20Jul%202013%2013%3A09%3A35%20GMT%22%2C%22userToken%22%3A%22AlexToken%22%7D

任何想法，为什么角的方式不起作用是AP preciated？

Any ideas why angular way does not work are appreciated?

更新，因为它原来是相当愚蠢的问题：因为我用PARAMS和代替数据：

Update the issue as it turns out to be quite silly: because I used params and instead of data in:

 $http({
                url: url,
                method: 'POST',
                params: { appContext: appContext },
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded'
                    /*'Accept': 'text/json'*/}
            }).success(successFn).error(errorFn);

角度转换成的GetRequest。不需要任何的ContentType。所以实际的code是

angular converted to GetRequest. No need for ContentType either. so actual code is

 $http({method: 'POST',
            url: url,                
            data: appCtx,
        }).success(successFn).error(errorFn);

所以几乎解决了，我看到的角仍然发出一个失败，但后请求经过...... OPTIONS请求

so ALMOST resolved, I see that angular still issues OPTIONS request that fails but post request goes through...

等等，一个任何想法都是pciated AP $ P $

so any ideas on that one are appreciated

推荐答案

我的问题是由于两方面的原因：我用PARAMS和代替数据

My issue were due to two reasons: I used params and instead of data in

 $http({
                url: url,
                method: 'POST',
                params: { appContext: appContext },
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded'
                    /*'Accept': 'text/json'*/}
            }).success(successFn).error(errorFn);

角度转换成的GetRequest。不需要任何的ContentType。所以实际的code是

angular converted to GetRequest. No need for ContentType either. so actual code is

 $http({method: 'POST',
            url: url,                
            data: appCtx,
        }).success(successFn).error(errorFn);

在服务器端我需要的东西处理选项的要求。一种方法是修饰方法W / [System.Web.Http.AcceptVerbs（选项），我不认为最好的方式。另一种方法是将自定义消息处理程序。我还在研究它......

on the server side I needed something handling OPTIONS request. One way is to decorate method w/ [System.Web.Http.AcceptVerbs("OPTIONS")], which I do not think the best way. Another way is to add Custom Message Handler. I am still researching it...
