在ASP.NET CORE Web应用程序中，我有一个class BookInfo(convrMgr: ConversationMgr, id: String, queue: RequestQueue, queueTag:String) {
val TAG = "BookInfo"
var title: String? = ""
init {
val url = "https://api.douban.com/v2/book/$id"
// Request a string response from the provided URL.
val stringRequest = StringRequest(Request.Method.GET, url,
Response.Listener<String> { response ->
Log.d(TAG + " Response", response.substring(0))
// Parse JSON from String value
val parser = Parser()
val jsonObj: JsonObject =
parser.parse(StringBuilder(response.substring(0))) as JsonObject
// Initial book title of book properties.
title = jsonObj.string("title")
Log.d(TAG + " Book title", title)
convrMgr.addNewMsg(title)
},
Response.ErrorListener { error -> Log.e(TAG + " Error", error.toString()) })
// Set the tag on the request.
stringRequest.tag = queueTag
// Add the request to the RequestQueue.
queue.add(stringRequest)
}
类和一个接口MyRepository来管理对存储库（数据库）的访问。
每次用户连接到应用程序（在站点上）时，我都需要在数据库中记录一个条目。
在Startup.cs中，我使用IMyRepository方法
ConfigureServices然后在public void ConfigureServices(IServiceCollection services)
{
// Adds services required for using options.
services.AddOptions();
// ...
services.AddSingleton<IMyRepository, MyRepository>();
方法中我需要更新数据库
Configure所以我的问题是如何/在哪里注入public void Configure(IApplicationBuilder app,
IHostingEnvironment env, ILoggerFactory loggerFactory) {
// ...
IMyRepository myRep = ??? // should inject somehow
// ...
app.UseOpenIdConnectAuthentication(new OpenIdConnectOptions
{
ClientId = Configuration["...ClientId"],
Authority = Configuration["...AADInstance"] + Configuration["...TenantId"],
CallbackPath = Configuration["...CallbackPath"],
Events = new OpenIdConnectEvents
{
OnTicketReceived = context =>
{
var user = (ClaimsIdentity)context.Ticket.Principal.Identity;
if (user.IsAuthenticated)
{
var firstName = user.FindFirst(ClaimTypes.GivenName).Value;
var lastName = user.FindFirst(ClaimTypes.Surname).Value;
var email = user.FindFirst(ClaimTypes.Email).Value;
var connectedOn = DateTime.UtcNow;
var userId = user.Name;
//
// HERE ADD the info in the DB via IMyRepository
//
myRep.AddUserInfo(userId, firstName, lastName, email, connectedOn);
}
return Task.FromResult(0);
}
}
});
// ...
}
以便在IMyRepository方法中使用它？
答案 0 :(得分：3)
修改您的Configure方法以获取其他参数IMyRepository myRep，只要您在ConfigureServices注册该参数，就会为其注入。
public void Configure(IApplicationBuilder app,
IHostingEnvironment env,
ILoggerFactory loggerFactory,
IMyRepository myRep) { ... }
