Question

我正在尝试通过.aspx文件执行代码。但是它显示了这个错误：

“ /”应用程序中的服务器错误。

描述：服务器上发生应用程序错误。目前   此应用程序的自定义错误设置阻止了   远程查看应用程序错误（出于安全原因）。   但是，可以由本地服务器上运行的浏览器查看它   机。        详细信息：要使此特定错误消息的详细信息可以在远程计算机上查看，请创建标签   在根目录中的“ web.config”配置文件中   当前Web应用程序。然后，此标签应   将其“模式”属性设置为“关闭”。

我现在无法检查服务器错误或更改其设置。

这是我的代码：

<%@ Page Language="C#"%>

<%@ import Namespace="System"%>
<%@ import Namespace="System.IO"%>
<%@ import Namespace="System.Linq"%>


<script runat="server">

            "...\\properties.txt"))
        {
            string line;

            while ((line = sr.ReadLine()) != null)
            {
                // Divide all '_'
                string[] lineParts = line.Split('_');

            }
        }
    }

private  string CorrectHtml(string url, string title, string initCode, string og_desc, string desc, string og_img)
    {
        string Html = "<html lang=\"en\">" +
        "<head>" +
            "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\"/>" +

            "<meta property=\"og:title\" content=\"\"/>" +
            "<meta property=\"og:description\" content=\"/*OG_DESCRIPTION*/\"/>" +
            "<meta property=\"og:image\" content=\"'/*OG_IMAGE*/'\"/>" +
            "<meta property=\"og:type\" content=\"website\"/>" +
            "<meta property=\"og:site_name\" content=\"\"/>" +

            "<script src=\"...properties/scripts.js\"></script>" +
            "<link rel=\"icon\" href=\"...properties/images/\">" +

        "<body>" +
            "<div id=\"main\" class=\\">" +
            "</div><!-- /#main -->" +
        "</body>" +
       "</html>";

        Html = Html.Replace("OG_URL", url).Replace("PAGE_TITLE", title).Replace("/*PAGE_INIT*/", initCode).Replace("/*OG_DESCRIPTION*/", og_desc)
            .Replace("/*DESCRIPTION_DESC*/", desc).Replace("/*OG_IMAGE*/", og_img);

        return Html;
    }
</script>

问题出在这部分上：

"<script>PAGE_INIT</script>" +
"<script src=\"...properties/scripts.js\"></script>"

编译器将其识别为新的runat脚本。解决方案是将包含脚本标签的字符串分开：

"<script>PAGE_INIT<" + "/script>" +
"<script src=\"...properties/scripts.js\"><" + "/script>"

在配置文件中，您可以通过在system.web中使用以下命令来关闭“自定义错误”选项：

<system.web>
    <customErrors mode="Off"/>
    <compilation debug="true"/>
    <authentication mode="None"/>
</system.web>
