[英]Sentry configuration in appsettings.json with Serilog in .Net Core 3 Console App
[英]Adding multiple endpoint routes to .net core console app from appsettings.json
我正在使用 .net 核心 3.1 來構建一個控制台應用程序,該應用程序充當事件處理程序 API。
該應用程序實時捕獲對數據庫的更改並將這些更改定向到其他 API。 將“customer”go 更新為“customerAPI”,“product”更新為“productAPI”等等。 這意味着我有一個 appsettings.Local.json 看起來像這樣:
"DBConnectionStrings": {
"DefaultConnection": "AccountEndpoint=(my account)",
"SourceDatabaseName": "MyDB",
"SourceContainerName": "MySource",
"LeasesContainerName": "MyLease",
"PartitionKey": "/id"
},
"EndpointAPIStrings": {
"Endpoint1": {
"EndpointUrl": "https://localhost:7777",
"Username": "myusername1",
"Password": "mypassword1",
"Endpoint2": {
"EndpointUrl": "https://localhost:8888",
"Username": "myusername2",
"Password": "mypassword2",
"Endpoint3": {
"EndpointUrl": "https://localhost:9999",
"Username": "myusername3",
"Password": "mypassword3"
...
}
我目前正在使用一種糟糕的方法將它們聲明為 EnvironmentVariables 以從我的 Main 中獲取它們,在該 Main 中將配置構建到我的 CallAPI 任務中。
主要的:
public static async Task Main(string[] args)
{
...
IConfiguration configuration = BuildConfiguration(environmentName);
CosmosClient cosmosClient = BuildCosmosClient(configuration);
Environment.SetEnvironmentVariable("EndpointUrl", configuration["EndpointAPIStrings:Endpoint1:EndpointURL"]);
Environment.SetEnvironmentVariable("Username", configuration["EndpointAPIStrings:Endpoint1:Username"]);
Environment.SetEnvironmentVariable("Password", configuration["EndpointAPIStrings:Endpoint1:Password"]);
...
}
代表 function:
...
if (entityType == "myproduct")
{
var entity = "products";
var result = await Task.Run(() => CallAPIAsync(entity, item));
}
...
任務調用API:
public static async Task<HttpResponseMessage> CallAPIAsync(string entity, ProcessedItem item)
{
using (var client = new HttpClient())
{
Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
var endpointUrl = Environment.GetEnvironmentVariable("EndpointUrl");
var uri = new Uri($"{endpointUrl}/api/{entity}/{item.Id}/propagate");
string username = Environment.GetEnvironmentVariable("Username");
string password = Environment.GetEnvironmentVariable("Password");
...
}
}
這顯然只適用於第一個端點,而忽略其他端點。
如何重構它以將所有 EndpointAPIStrings 的值放入我的 CallAPI 任務中?
您可以為其創建一個 class 並將值讀入該 class。 也將其更改為 JSON 中的列表會很好。 我會做的步驟:
將“EndpointAPIStrings”更改為數組:
{ "EndpointAPIStrings":[ { "Id":"Endpoint1", "EndpointUrl":"https://localhost:7777", "Username":"myusername1", "Password":"mypassword1" }, { "Id":"Endpoint2", "EndpointUrl":"https://localhost:8888", "Username":"myusername2", "Password":"mypassword2" }, { "Id":"Endpoint3", "EndpointUrl":"https://localhost:9999", "Username":"myusername3", "Password":"mypassword3" } ] }
創建一個 C# class 定義 JSON 數組中的對象:
public sealed class EndPoint { public string Id { get; set; } public string EndPointUrl { get; set; } public string Username { get; set; } public string Password { get; set; } }
從配置中檢索更改數據:
IConfiguration configuration = BuildConfiguration(environmentName); CosmosClient cosmosClient = BuildCosmosClient(configuration); List<EndPoint> endPoints = configuration.GetSection("EndPointAPIStrings").Get<List<EndPoint>>();
現在您的所有端點都在endPoints
變量中。 您可以按照自己的喜好刪除和添加屬性到 JSON 中,您唯一需要做的就是相應地更改 class。 請注意,您需要在 JSON 和 C# class 中使用相同的名稱才能成功映射。
我在 Windows 服務 .net Core 3.1 應用程序中完成了此操作,非常相似。 本質上,當您在 program.cs 中調用 IHostBuilder function
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.UseWindowsService()
.ConfigureLogging(loggerFactory => loggerFactory.AddEventLog())
.ConfigureServices((hostContext, services) =>
{
services.AddHostedService<Worker>();
});
默認情況下,您可以從 appsettings.json 訪問配置變量。 然后可以在您的主啟動中訪問或執行 function:
private readonly ILogger<Worker> _logger;
private readonly IServiceScopeFactory _serviceScopeFactory;
private readonly IConfiguration _config;
public Worker(ILogger<Worker> logger, IServiceScopeFactory serviceScopeFactory, IConfiguration config)
{
_logger = logger;
_serviceScopeFactory = serviceScopeFactory;
_config = config;
}
然后在你的主要或執行function:
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
// Must be a scoped process in order to run correctly
using var scope = _serviceScopeFactory.CreateScope();
// Start timer and begin log
var startTime = DateTime.UtcNow;
var env = _config.GetValue<string>("ENV");
var stageTable = _config.GetValue<string>("StageTable");
var prevTable = _config.GetValue<string>("PrevTable");
var mainTable = _config.GetValue<string>("MainTable");
var sqlConnectionString = _config.GetValue<string>("SqlConnString_" + env);
var excelConnectionString = _config.GetValue<string>("ExcelConnectionString1") +
_config.GetValue<string>("ExcelFilePath_" + env) +
_config.GetValue<string>("ExcelFileName") +
_config.GetValue<string>("ExcelConnectionString2");
使用 appsettings.json 像:
"ENV": "LOCAL",
"StageTable": "Staging",
"PrevTable": "Previous",
"MainTable": "Courses",
