.NET Core 中读取appsettings.json配置文件的方法

appsettings.json配置文件结构如下：

{

"WeChatPay": {
"WeChatApp_ID": "wx9999998999",
"WeChatMCH_ID": "1880000000",
"WeChatApp_secret": "123ggg456ddfd355dsa"
}
}

Startup.cs 配置文件 Services

public void ConfigureServices(IServiceCollection services)
{
//微信支付配置文件 配置Services
services.Configure<WeChatPayOptions>(Configuration.GetSection("WeChatPay"));
//////////////////////////////////////////////////////////////////////////////////
}

然后把设置注入进相应的Controller后就可以使用了

public class HomeController : Controller
{
//把设置注入进相应的Controller
private WeChatPayOptions WeChatPayConfigSettings { get; set; }

public HomeController(IOptions<WeChatPayOptions> settings)
{
WeChatPayConfigSettings = settings.Value;
}

[HttpPost]
public IActionResult Test([FromBody]JObject postVal)
{

string appid = WeChatPayConfigSettings.WeChatApp_ID;
string mchid = WeChatPayConfigSettings.WeChatMCH_ID;
string appkey = WeChatPayConfigSettings.WeChatApp_secret;
return AsResult.Success(appkey+ appid+mchid );
}

models 中的实体类结构：

WeChatPayOptions

public class WeChatPayOptions
{

public string WeChatApp_ID { get; set; }
public string WeChatMCH_ID { get; set; }
public string Gatewayurl { get; set; }
public string WeChatApp_secret { get; set; }

}
