未在最终HTTP响应中添加自定义标头-AWS .NET Lambda SDK中的APIGatewayHttpApiV2ProxyResponse类日志环境

如何解决未在最终HTTP响应中添加自定义标头-AWS .NET Lambda SDK中的APIGatewayHttpApiV2ProxyResponse类日志环境

说明

我正在使用不带Amazon.Lambda.AspNetCoreServer软件包的AWS Lambda BUT，一切正常，除了我添加了一些基本的自定义响应标头（例如JSON内容类型）并且最终未添加任何内容之外HTTP响应标头。

在我的特定情况下，我没有使用Amazon.Lambda.AspNetCoreServer，因为我正在构建无服务器框架模板。

这是我的Lambda函数实现： https://github.com/RichardSilveira/UserServerlessMicroservice/blob/master/src/userService/Functions/GetUserByIdFunction.cs

    public class GetUserByIdFunction : FunctionBase
    {
        private IUserRepository _userRepository;

        protected override void ConfigureServices(IServiceCollection serviceCollection)
        {
            var connString = Configuration["UserServiceDbContextConnectionString"];

            // serviceCollection.AddDbContext<UserContext>(options => options.UseMysqL(connString));
            serviceCollection.AddDbContext<UserContext>(options => options.UseInMemoryDatabase(connString));//temporarily

            serviceCollection.AddScoped<IUserRepository,UserRepository>();
        }

        protected override void Configure(IServiceProvider serviceProvider)
        {
            _userRepository = serviceProvider.GetService<IUserRepository>();
        }

        // Invoked by AWS Lambda at runtime
        public GetUserByIdFunction()
        {
        }

        public GetUserByIdFunction(
            IConfiguration configuration,IUserRepository userRepository)
        {
            // Constructor used by tests
            _userRepository = userRepository;
        }


        public async Task<APIGatewayHttpApiV2ProxyResponse> Handle(APIGatewayHttpApiV2ProxyRequest request,ILambdaContext context)
        {
            LogFunctionMetadata(request,context);

            if (!RunningAsLocal) ConfigureDependencies();

            var userId = Guid.Parse(request.PathParameters["userid"]);

            var user = await _userRepository.GetByIdAsync(userId);
            if (user == null) return NotFound();

            return Ok(user);
        }
    }

我的函数库实现 https://github.com/RichardSilveira/UserServerlessMicroservice/blob/master/src/userService/Functions/FunctionBase.cs

    public abstract class FunctionBase
    {
        protected IConfiguration Configuration { get; private set; }
        protected bool RunningAsLocal = false;

        public FunctionBase() => Configuration = ConfigurationService.Instance.Configuration;

        public FunctionBase(IConfiguration configuration)
        {
            Configuration = configuration;
            RunningAsLocal = true;
        }

        protected void ConfigureDependencies()
        {
            var serviceCollection = new ServiceCollection();
            ConfigureServices(serviceCollection);
            Configure(serviceCollection.BuildServiceProvider());
        }

        protected abstract void ConfigureServices(IServiceCollection serviceCollection);
        protected abstract void Configure(IServiceProvider serviceProvider);

        protected void LogFunctionMetadata(APIGatewayHttpApiV2ProxyRequest request,ILambdaContext context)
        {
            LambdaLogger.Log($"CONTEXT {Serialize(context.GetMainProperties())}");
            LambdaLogger.Log($"EVENT: {Serialize(request.GetMainProperties())}");
        }

        protected APIGatewayHttpApiV2ProxyResponse Ok() =>
            new APIGatewayHttpApiV2ProxyResponse()
            {
                StatusCode = (int) HttpStatusCode.OK,Headers = new Dictionary<string,string>
                {
                    {"Content-Type","application/json"}
                }
            };

        protected APIGatewayHttpApiV2ProxyResponse NotFound() =>
            new APIGatewayHttpApiV2ProxyResponse()
            {
                StatusCode = (int) HttpStatusCode.NotFound,"application/json"}
                }
            };
    }

唯一的问题是添加到APIGatewayHttpApiV2ProxyResponse类的任何标头都没有按预期方式添加到最终HTTP响应中。

注意：我已经尝试使用它的SetHeaderValues，例如：

      protected APIGatewayHttpApiV2ProxyResponse Ok(object body)
        { 
            var response = new APIGatewayHttpApiV2ProxyResponse()
            {
                StatusCode = (int) HttpStatusCode.OK,Body = Serialize(body)
            };
            
            response.SetHeaderValues("Content-Type","application/json",false);
            response.SetHeaderValues("Access-Control-Allow-Origin","*",false);
            response.SetHeaderValues("Access-Control-Allow-Credentials","true",false);

            return response;
        }

复制步骤

git clone https://github.com/RichardSilveira/UserServerlessMicroservice cd UserServerlessMicroservice cd src/userService npm i -g serverless

注意：无服务器框架会在Cloudformation上创建一个抽象层，这意味着将一个堆栈部署到AWS账户中，您可以轻松删除该堆栈-您将在该堆栈上不收取任何费用。

provider:
  name: aws
  profile: default
  runtime: dotnetcore3.1
  stage: dev
  region: sa-east-1

您可以通过添加serverless.yml（例如上例中的示例）从profile: <name>文件中的本地计算机AWS凭证文件中通知配置文件名称。这是可选的，如果不执行任何操作，将使用默认配置文件。

build sls deploy -v

有什么想法吗？

谢谢！

解决方法

您是否已将“ application / json”添加到API Gateway的媒体类型？还是那是默认的？我知道我必须添加“ application / octet-stream”。

已解决

按如下所示创建响应很好

input:-webkit-autofill,input:-webkit-autofill:hover,input:-webkit-autofill:focus,input:-webkit-autofill:active,input:-webkit-autofill::first-line {
  font-size: 18px;
}

而不是将其他词典分配给Headers属性
