Question

我尝试将Hangfire与SQL Server一起使用，从 appsettings.json 文件中读取连接字符串。它不起作用。只有当我提供 UseSqlServerStorage 方法的连接字符串时，它才有效。

此处 appsettings.json ：

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

这里是在 Startup.ConfigureServices 中配置Hangfire的行：

{
  "ConnectionStrings": {
    "HangfireDemo": "Data Source=VSQL64;Initial Catalog=HangfireDemo;Integrated Security=SSPI;"
  },
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Debug",
      "System": "Information",
      "Microsoft": "Information"
    }
  }
}

如果我写＆＃34; HangfireDemo＆＃34;在 UseSqlServerStorage 方法中，它不起作用。此方法中只有完整的连接字符串有效我怎样才能提供连接字符串名称？

你应该可以这样做：

public Startup(IHostingEnvironment env)
{
    var builder = new ConfigurationBuilder()
        .SetBasePath(env.ContentRootPath)
        .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
        .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);


    builder.AddEnvironmentVariables();
    Configuration = builder.Build();

}


public IConfigurationRoot Configuration { get; }

public void ConfigureServices(IServiceCollection services)
{
    services.AddHangfire(configuration => 
    configuration.UseSqlServerStorage(Configuration.GetConnectionString("HangfireDemo"))
    );  

}

从ASP.NET CORE Web应用程序中的appsettings.json加载Hangfire配置
