发布到Azure时“/”应用程序中的服务器错误
发布到Azure时“/”应用程序中的服务器错误
提问于 2015-04-20 08:47:33
我从我以前的一个NopCommerce网站复制了源代码，复制并重命名了Azure上的数据库，并更新了settings.txt文件以指向新的数据库。唯一的其他更改是对css的更改。
当我在本地主机上运行新站点时，它运行得非常完美，没有任何问题，但是，当我从VS发布到Azure，然后浏览到URL时，我会在'/‘Application中得到一个错误-服务器错误。对于我的生活，我无法弄清楚这个问题，我想知道是否还有其他人经历过这件事。
我用的是Nop 3.5
我的直觉告诉我，我的连接字符串有问题，然而，为什么要在本地主机上工作，而不是在发布时？
下面是异常详细信息和堆栈跟踪
提前感谢您的帮助
'/‘应用程序中的服务器错误。参数'nameOrConnectionString‘不能为空，也不能只包含空白。描述:在执行当前web请求时发生了未处理的异常。请查看堆栈跟踪以获得有关错误的更多信息，以及它起源于代码的位置。
异常详细信息: System.ArgumentException:参数'nameOrConnectionString‘不能为空、空或只包含空白。
源错误：
生成此未处理异常的源代码只能在调试模式下编译时显示。要启用此功能，请执行以下步骤之一，然后请求URL：
- 在生成错误的文件顶部添加"Debug=true“指令。示例：
或者：
2)将以下部分添加到应用程序的配置文件中：
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>请注意，第二种技术将导致以调试模式编译给定应用程序中的所有文件。第一种技术只会导致在调试模式下编译特定的文件。
重要:在调试模式下运行应用程序确实会导致内存/性能开销。在部署到生产场景之前，应确保应用程序已禁用调试。

从我的评论中的链接，我认为我需要在下面定义连接字符串？来自NopObjectContext.cs
namespace Nop.Data
{
/// <summary>
/// Object context
/// </summary>
public class NopObjectContext : DbContext, IDbContext
{
#region Ctor
public NopObjectContext(string nameOrConnectionString)
: base(nameOrConnectionString)
{
//((IObjectContextAdapter) this).ObjectContext.ContextOptions.LazyLoadingEnabled = true;
}
}

在NopCommerce中，连接字符串是在一个名为Settings.txt的文件中设置的，该文件位于Presnetation\Nop.Web\App_Data文件夹中。但是，它不是解决方案的一部分，因此不会被部署。你可以：
- 手动发布该文件。
- 将该文件添加到您的
Nop.Web项目并进行部署。

好的，这是我发现的。
如果DNS_PROBE_FINISHED_NXDOMAIN错误100%正确，则settings.txt在App_Data中的语句。问题是，URL提供的http://yourwebsite.azurewebsites.net/不起作用，直到自定义域连接起来并用于导航到该站点按预期运行的网站。
