Blazor WebAssembly:使用构造函数注入将Blazored.LocalStorage注入到服务中

Question

Blazored.LocalStorage包是：

一个库，用于访问Blazor应用程序中的本地存储

将服务注入组件很容易：

@inject Blazored.LocalStorage.ILocalStorageService localStorage

如果我们想把它注入后面的代码中：

[Inject]
private ILocalStorageService localStorage { get; set; }

但假设我想把它注入另一个服务(比如说集中控制(：

public class StorageManagement
{
public StorageManagement(LocalStorageService localStorage)
{
//How to initialize it here?
}
}

我不知道如何初始化StorageManagement构造函数中的服务实例，也不知道如何在Program.cs:中设置StorageManagement构造函数的参数

builder.Services.AddSingleton(e => new StorageManagement(//?));

Answer 1

只有builder.Services.AddBlazoredLocalStorage();或builder.Services.AddBlazoredLocalStorage(config => config.JsonSerializerOptions.WriteIndented = true);，正如README中所解释的那样
然后是builder.Services.AddScoped<StorageManagement>();或builder.Services.AddScoped(p => new StorageManagement(p.GetRequiredSerice<ILocalStorageService>()));

但是您的服务应该采用ILocalStorageService而不是LocalStorageService实例：

public class StorageManagement
{
public StorageManagement(ILocalStorageService localStorage)
{
//How to initialize it here?
}
}

Answer 2

您的构造函数中没有使用接口ILocalStorageServer，它应该是

public class StorageManagement
{
private readonly ILocalStorageService LocalStorage;

public StorageManagement(ILocalStorageService localStorage)
{
LocalStorage = localStorage;
}
}
