Question

我有一个仅在将Web应用程序部署到服务器上时才发生的问题（错误500）。在本地运行该应用程序时，没有错误。

我有一个名为“ TestUnitaire.cshtml”的视图，我得到的错误是我调用XmlPreview操作的那一行。

<div class="row">
    <div id="partialTestUnitaireConfig" class="col-lg-8">
        @Html.Action("TestUnitaireConfig", "CommandeTest", new { testId = Model })
    </div>

    <div id="partialXmlPreview" class="col-lg-4 xmlPreview">
        @Html.Action("XmlPreview", "CommandeTest", new { testId = Model })
    </div>
</div>

在相应的控制器中，方法如下所示：

[HttpGet]
[AuthorizeUser(ProfilList.Superuser, ProfilList.Administrateur, ProfilList.Visiteur)]
public ActionResult TestUnitaireConfig(int? testId = null)
{
    var ctu = new CTU();
    return PartialView("_TestUnitaireConfig", ctu);
}

[HttpGet]
[AuthorizeUser(ProfilList.Superuser, ProfilList.Administrateur, ProfilList.Visiteur)]
public ActionResult XmlPreview(int? testId = null)
{
    var ctu = new CTU();
    return PartialView("_XMLPreview", ctu);
}

例外：

Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.

我不确定是什么问题导致它仅在部署应用程序时不起作用。如有需要，我将乐意提供更多详细信息。

预先感谢您的帮助。

看看Error executing child request for handler in view。也许上述提到的一种方法也适用于您。由于它可以在本地运行，但不能在Azure上运行，我怀疑项目配置有问题，例如数据库连接字符串（也许您没有为Azure更新cnn）

执行处理程序的子请求时出错（仅在服务器上部署应用程序）
