.net core 3.1 Console App找不到配置文件'appsettings.json'
如何解决.net core 3.1 Console App找不到配置文件''appsettings.json''？
在本地环境之外运行控制台应用程序时，.net core 3.1在与程序执行位置不同的目录中查找appsettings.json文件。
- 找不到配置文件''appsettings.json''，它不是可选的。物理路径为“ C：\ windows \ system32 \ appsettings.json”。
在早期版本的dotnet中，使用Environment.CurrentDirectory或Directory.GetCurrentDirectory（），但在3.1中不起作用。您如何更改它以使其在运行目录中显示？以下不起作用
using var host = Host.CreateDefaultBuilder()
.ConfigureHostConfiguration(builder =>
{
builder.SetBasePath(Environment.CurrentDirectory);
builder.AddCommandLine(args);
})
.UseConsoleLifetime(options => options.SuppressstatusMessages = true)
.UseServiceProviderFactory(new AutofacServiceProviderFactory())
.ConfigureAppConfiguration((hostContext,builder) =>
{
builder.AddJsonFile("appsettings.json");
hostContext.HostingEnvironment.EnvironmentName = Environment.GetEnvironmentvariable("NETCORE_ENVIRONMENT");
if (hostContext.HostingEnvironment.EnvironmentName == Environments.Development)
{
builder.AddJsonFile($"appsettings.{hostContext.HostingEnvironment.EnvironmentName}.json",optional: true);
builder.AddUserSecrets<Program>();
}
})
解决方法
这似乎可以通过在设置基本路径之前从AppDomain.CurrentDomain获取基本目录来实现。我仍然不明白为什么以前的dotnet版本中不需要这样做，而且我也找不到与此有关的任何MS文档。
Directory.SetCurrentDirectory(AppDomain.CurrentDomain.BaseDirectory);
using var host = Host.CreateDefaultBuilder()
.ConfigureHostConfiguration(builder =>
{
builder.SetBasePath(Directory.GetCurrentDirectory());
builder.AddCommandLine(args);
})
我们添加这样的应用设置：
public Startup(IWebHostEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json",optional: false,reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json",optional: true)
.AddEnvironmentVariables();
...
}

.net core 中如何读取 appsettings.json 相关配置
appsettings.json如下
{
"Logging": {
"LogLevel": {
"Default": "Debug",
"System": "Information",
"Microsoft": "Information"
},
"AllowedHosts": "*"
},
"ConfigSetting": {
"Ctu": 1,
"Btu": "Btu",
"Atu": "Atu"
}
}建立实体ConfigSetting
public class ConfigSetting
{
public int Ctu { get; set; }
public string Btu { get; set; }
public string Atu { get; set; }
}Startup配置
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
services.Configure<ConfigSetting>(Configuration.GetSection("ConfigSetting"));
}Controller配置
[Route("api/[controller]")]
[ApiController]
public class ValuesController : ControllerBase
{
private readonly IOptions<ConfigSetting> _ConfigSettingt;
public ValuesController(IOptions<ConfigSetting> ConfigSetting)
{
_ConfigSettingt = ConfigSetting;
}
[HttpGet("{id}")]
public ActionResult<string> Get(int id)
{
return _ConfigSettingt.Value.Atu;
}
}
.net core 中如何运用 appsettings.json 进行配置开发、生产不同配置
.net core 默认会有 appsettings.Development.json 文件，这是根据ASPNETCORE_ENVIRONMENT来读取的。
新建架构appsettings.Production.json用于生成环境
开发调试时通过此处进行配置。
正式环境发布
IIS版本 - - - 通过生成的 web.config 进行配置 ASPNETCORE_ENVIRONMENT 环境变量
<?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=".\TTTTTTTTT.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="InProcess">
<environmentVariables>
<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Production" /><!--Development-->
</environmentVariables>
</aspNetCore>
</system.webServer>
</location>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Credentials" value="true" />
</customHeaders>
</httpProtocol>
</system.webServer>
</configuration>后续更新。。。。
