在Blazor WebAssembly应用程序中,可以使用本地存储或浏览器的IndexedDB来安全地存储应用程序密钥。下面是一个示例解决方法,使用本地存储来存储密钥:
LocalStorageService.cs
的服务类,用于处理本地存储操作:using Microsoft.JSInterop;
using System.Threading.Tasks;
public interface ILocalStorageService
{
Task SetItemAsync(string key, T value);
Task GetItemAsync(string key);
Task RemoveItemAsync(string key);
}
public class LocalStorageService : ILocalStorageService
{
private readonly IJSRuntime _jsRuntime;
public LocalStorageService(IJSRuntime jsRuntime)
{
_jsRuntime = jsRuntime;
}
public async Task SetItemAsync(string key, T value)
{
await _jsRuntime.InvokeVoidAsync("localStorage.setItem", key, value);
}
public async Task GetItemAsync(string key)
{
return await _jsRuntime.InvokeAsync("localStorage.getItem", key);
}
public async Task RemoveItemAsync(string key)
{
await _jsRuntime.InvokeVoidAsync("localStorage.removeItem", key);
}
}
ILocalStorageService
:@inject ILocalStorageService LocalStorageService
ILocalStorageService
来存储和获取密钥:private async Task StoreKey(string key)
{
await LocalStorageService.SetItemAsync("AppKey", key);
}
private async Task GetKey()
{
return await LocalStorageService.GetItemAsync("AppKey");
}
这样,你就可以安全地将应用程序密钥存储在本地存储中,以便在Blazor WebAssembly应用程序中使用。请注意,本地存储是特定于浏览器的,因此在不同的浏览器或设备上,存储的密钥可能会有所不同。
