使用带有 Pipedream SSE API 的 ServiceStack ServerEventsClient 找不到 404 错误

Question

I'm using Pipedream as a data source which provides event data via an SSE API.

As per the instructions here , I'm using the following code to subscribe to the SSE:

var client = new ServerEventsClient("https://api.pipedream.com/sources/dc_mXugEA/sse")
{
    EventStreamRequestFilter = req => req.AddBearerToken("[MYTOKEN]"),
    OnMessage = message => Console.WriteLine(message.Json)
}.Start();

However, I get a System.Net.WebException with the message 'The remote server returned an error: (404) Not Found.'

But if I use HttpClient directly, it succeeds:

var client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "[MYTOKEN]");

using var reader = new StreamReader(await client.GetStreamAsync("https://api.pipedream.com/sources/dc_mXugEA/sse"));
while (!reader.EndOfStream)
{
    Console.WriteLine($"Received message: {await reader.ReadLineAsync()}");
}

Of course, I want to use ServerEventsClient instead of HttpClient to avoid the boilerplate looping code. But why is ServerEventsClient not working in this case?

ServiceStack 的服务器事件客户端仅适用于 ServiceStack 的服务器事件功能，即它不能用于使用 3rd Party SSE 流。
