【问题描述】:
我尝试为我的 ASP.NET Core 2.0 应用程序设置“dev”和“prod”环境,但它不起作用...这是我的配置:
appsettings.json的内容(和appsettings.Development.json完全一样)
{
"Logging": {
"IncludeScopes": false,
"LogLevel": { "Default": "Warning" }
},
"ConnectionStrings": {
"MyAppContext":
"...AccountName=MyApptables4dev; AccountKey=xxxxxx==;EndpointSuffix=core.windows.net"
},
"Authentication": {
"AzureAd": {
"AADInstance": "https://login.microsoftonline.com/",
"CallbackPath": "/signin-oidc",
"ClientId": "xxxxxxx",
"Domain": "MyAppapp-dev.azurewebsites.net",
"TenantId": "yyyyyyy"
}
}
}
对于 appsettings.Production.json 只是连接字符串和域名更改:
"MyAppContext":"...AccountName=MyApptables4dev;AccountKey=yyyyyy==;EndpointSuffix=core..."
和
"Domain": "MyAppapp.azurewebsites.net",
Startup.cs:
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, reloadOnChange: true);
if (env.IsDevelopment())
{
builder = builder.AddUserSecrets<Startup>();
}
builder.AddEnvironmentVariables();
Configuration = builder.Build();
}
public void ConfigureServices(IServiceCollection services)
{
// Adds services required for using options.
services.AddOptions();
// Register the IConfiguration instance which "ConnectionStrings" binds against.
//services.Configure<ConnectionStrings>(Configuration.GetSection("ConnectionStrings"));
services.Configure<AppSecrets>(Configuration);
services.AddSingleton<ITableRepositories, TableClientOperationsService>();
// ...
secrets.json(位于用户文件夹中)内容
{
"MyAppTablesConnectionString": "DefaultEndpointsProtocol=https;AccountName=myapptables4dev;AccountKey=xxx==;EndpointSuffix=core.windows.net"
}
最后是访问数据库的类(在我的例子中是 AzureTables)
public class TableClientOperationsService : ITableRepositories
{
// ...
public TableClientOperationsService() { }
public TableClientOperationsService(IOptions<AppSecrets> optionsAccessor)
{
tables = new Dictionary<string, CloudTable>();
// 'null' in 'prod'!
connectionString = optionsAccessor.Value.MyAppTablesConnectionString;
}
知道MyAppTablesConnectionString 在“生产”中是“null”,也许问题出在那儿,但我不知道如何使它与MyAppContext 和MyAppTablesConnectionString 连接字符串一起工作。 .
