在ASP.NET Core和GraphQL结合使用时,使用JWT进行身份验证可能涉及以下问题和解决方法:
Microsoft.AspNetCore.Authentication.JwtBearer
包。以下是一个使用该包的示例代码:// Startup.cs
public void ConfigureServices(IServiceCollection services)
{
// 添加身份验证服务
services.AddAuthentication(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"))
};
});
// ...
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
// 使用身份验证中间件
app.UseAuthentication();
// ...
}
[Authorize] // 需要身份验证
public class MyQuery
{
// ...
}
public class MyMutation
{
[Authorize] // 需要身份验证
public Task DoSomething([FromServices] MyService service)
{
// ...
}
}
public class GraphQLUserContext : IProvideClaimsPrincipal
{
public ClaimsPrincipal User { get; set; }
}
public class GraphQLMiddleware
{
private readonly RequestDelegate _next;
public GraphQLMiddleware(RequestDelegate next)
{
_next = next;
}
public async Task InvokeAsync(HttpContext httpContext, MyDbContext dbContext)
{
if (httpContext.User.Identity.IsAuthenticated)
{
var userContext = new GraphQLUserContext
{
User = httpContext.User
};
httpContext.Items["GraphQLUserContext"] = userContext;
}
await _next(httpContext);
}
}
public class Startup
{
public void Configure(IApplicationBuilder app)
{
// ...
app.UseMiddleware();
app.UseGraphQL();
// ...
}
}
public class MyQueryResolver
{
public async Task> GetUsers([GraphQLUserContext] GraphQLUserContext userContext)
{
// 检查用户是否有权限访问该查询
if (!userContext.User.HasClaim("role", "admin"))
{
throw new UnauthorizedAccessException("You are not authorized to access this resource.");
}
// 获取用户列表
return await userRepository.GetUsersAsync();
}
}
这些是使用ASP.NET Core和GraphQL进行JWT身份验证的一些常见问题和解决方法。请根据实际需求进行适当调整和扩展。
