在Azure移動服務中啟用CORS-未授權的選項

Question

我正在使用Azure移動服務創建.Net Web服務。 服務本身可以正常工作，但是我想啟用CORS。

我的Global.asax包含：

protected void Application_BeginRequest(object sender, EventArgs e)
{
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
    if (HttpContext.Current.Request.HttpMethod != "OPTIONS") return;
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET,POST");
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers",
        "Authorization, Origin, Content-Type, Accept, X-Requested-With,x-zumo-application,x-zumo-installation-id");
    HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
    HttpContext.Current.Response.End();
}

我的WebAPIConfig.cs包含：

    public static void Register()
    {
        ConfigOptions options = new ConfigOptions();
        HttpConfiguration config = ServiceConfig.Initialize(new ConfigBuilder(options));

        var cors = new EnableCorsAttribute("*", "*", "*","*");
        config.EnableCors(cors);

        config.Routes.MapHttpRoute("DefaultApiWithAction", "Api/{controller}/{action}");
    }

這里有一個在移動服務中啟用CORS的解決方法：

https://gist.github.com/HenrikFrystykNielsen/6c934be6c6c8fa9e4bc8

您不需要Application_BeginRequest部分-請求/響應不通過該代碼路徑-它們通過OWIN管道。 好消息是，您只需要上面的要點即可開始。

希望這可以幫助！
