c# - 使用 IIS 时出现多个错误

标签 c# .net entity-framework asp.net-core iis

我最近使用 angular asp.net-core 和 SQLserver 完成了我的约会应用程序项目，我尝试将该项目发布到 IIS。

当我在本地运行项目时，所有请求都得到了理想的响应，并且工作正常，但是当我从 IIS 服务器打开网站时，应用程序运行正常，但任何请求都会返回 500 代码响应。 在我的 web.config 文件中将 stdoutLogEnabled 设置为“true”后，我看到有多个错误:

fail: Microsoft.EntityFrameworkCore.Database.Command[20102]

      Failed executing DbCommand (11ms) [Parameters=[], CommandType='Text', CommandTimeout='60']

      CREATE DATABASE [Datingapp];

似乎所有错误都绑定(bind)到 ef，它无法连接到 sqlserver(身份验证是基于 windows 的，如果重要的话......)，正如我在本地所说的那样，它工作正常。

web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\DatingApp.API.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>
  • .NET 托管 IIS 已安装并且是最新的。

有什么想法吗？

最佳答案

连接字符串指向错误的数据库或用于连接数据库的应用程序池标识没有足够的权限访问数据库。

尝试将应用程序池身份设置为具有访问 SQL Server 数据库的完全权限的自定义帐户(admin 用户)。

给他们一个服务器角色，让他们凭据创建数据库。设置 db_owner 和 public。
