骨干RESTful同步：无法在IIS 7.5上启用PUT和DELETE

Question

我尝试了Stack Overflow上的所有解决方案，但没有成功。

我的web.config包含：

<system.webServer>
    <modules>
        <remove name="WebDAVModule" />
    </modules>
    <handlers>
        <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
        <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
    <httpProtocol>
        <customHeaders>
            <add name="Access-Control-Allow-Origin" value="*" />
            <add name="Access-Control-Allow-Methods" value="POST, GET, DELETE, PUT, OPTIONS" />
            <add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept" />
        </customHeaders>
    </httpProtocol>
</system.webServer>

我总是得到：

在我的应用中，我做了：

this.model.save({ firstname: name[0], lastname: name[1] });

我的收藏是：

app.AttendeeCollection = Backbone.Collection.extend({
    url: 'http://test-backbone/attendee',
    model: app.AttendeeModel
});

我的C＃：

[AcceptVerbs(HttpVerbs.Put)]
public JsonResult Index(int id, Attendee updatedAttendee)
{
    var attendee = db.Attendees.Where(a => a.id == id).FirstOrDefault();

    attendee.firstname = updatedAttendee.firstname;
    attendee.lastname = updatedAttendee.lastname;

    db.SaveChanges();

    return Json(attendee, JsonRequestBehavior.DenyGet);
}

问题

• 任何想法？
• 有没有办法用POST替换PUT和DELETE？ ：（

我认为您正在寻找emulateHTTP：

  

emulateHTTP Backbone.emulateHTTP = true

     

如果您想使用不支持Backbones默认REST / HTTP方法的旧版Web服务器，您可以选择启用Backbone.emulateHTTP。设置此选项会使用HTTP PUT伪造DELETE和POST个请求，并使用true方法设置X-HTTP-Method-Override标头。

您可能需要调整服务器代码以查看X-HTTP-Method-Override。
