在Blazor WASM项目中,如果无法调试GetAuthenticationStateAsync方法,可以尝试以下解决方法:
确保在调用GetAuthenticationStateAsync之前,已经正确配置了身份验证服务。
builder.Services.AddAuthorizationCore();
builder.Services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
}).AddJwtBearer(options =>
{
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true,
ValidIssuer = "your_issuer",
ValidAudience = "your_audience",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("your_secret_key"))
};
});
确保在调用GetAuthenticationStateAsync之前,已经在组件中添加了身份验证注入。
@using Microsoft.AspNetCore.Authorization
[Authorize]
public class MyComponent : ComponentBase
{
// Component code here
}
确保在调用GetAuthenticationStateAsync之前,已经在组件中注入了AuthenticationStateProvider服务。
@inject AuthenticationStateProvider AuthenticationStateProvider
public class MyComponent : ComponentBase
{
[Inject] protected NavigationManager NavigationManager { get; set; }
protected override async Task OnInitializedAsync()
{
var authState = await AuthenticationStateProvider.GetAuthenticationStateAsync();
// Authentication state handling code here
}
}
通过以上步骤,你应该可以在Blazor WASM项目中成功调试GetAuthenticationStateAsync方法。
