API 未找到网关 Websocket @Connection 端点

Question

我正在尝试从 $connect 路由向可能连接的客户端发送套接字消息。我成功地从 dynamodb 检索了连接 ID。每当我尝试发送任何东西时，我都会收到错误消息：

No method found matching route %40connections/aM50DdTXCYcCGEA%3D for http method POST

我用来发送的代码：

Amazon.Runtime.AWSCredentials cd = new Amazon.Runtime.BasicAWSCredentials("*******", "******");

var domainName = request.RequestContext.DomainName;
var endpoint = $"https://{domainName}/{stage}";
context.Logger.LogLine($"API Gateway management endpoint: {endpoint}");

 apiClient = new AmazonApiGatewayManagementApiClient(cd,
                new AmazonApiGatewayManagementApiConfig
                {
                    ServiceURL = endpoint,
                    RegionEndpoint = Amazon.RegionEndpoint.USEast2
                });
Message testMessage = new Message()
            {
                AppId = "TestApp",
                CommandData = "Testing"
            };


MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(testMessage)));

PostToConnectionResponse response = await apiClient.PostToConnectionAsync(new PostToConnectionRequest()
                    {
                        ConnectionId = Uri.EscapeUriString(existing.ConnectionId),
                        Data = stream
                    });

我似乎找不到任何可以说明为什么 POST 的端点不工作的原因（我在 nodejs 中有一个工作示例，但我们需要在 .Net 中完成）。如果有人对我如何找到问题所在有任何建议，我们将不胜感激。

我已确认端点与部署的 WebSocket API 网关 url 匹配。

我做了更多更少的相同代码并且有效

        AmazonApiGatewayManagementApiClient client = new AmazonApiGatewayManagementApiClient(new AmazonApiGatewayManagementApiConfig() {
            ServiceURL = "https://" + request.RequestContext.DomainName + "/" + request.RequestContext.Stage
        });

        MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(document)));
        PostToConnectionRequest postRequest = new PostToConnectionRequest()
        {
            ConnectionId = request.RequestContext.ConnectionId,
            Data = stream
        };

        var result = client.PostToConnectionAsync(postRequest);
        result.Wait();

我最终删除了所有 IAM 角色和 re-made 它们。我猜有些地方配置错误，或者如果 IAM 使用任何类型的缓存系统，它可能会锁定到旧版本。它现在正在工作。很抱歉延迟 post 我的发现！
