如何订阅coinbase websocket？

Question

我所提及的资源如下：

https://docs.cloud.coinbase.com/exchange/docs/websocket-overview https://docs.cloud.coinbase.com/exchange/docs/websocket-channels

在连接到wss://ws-feed.exchange.coinbase.com之后，我发送了一条订阅消息，但它总是被服务器拒绝。

示例1:

To coinbase:
{
    "type": "subscribe",
    "product_ids": [
        "ETH-USD",
        "ETH-EUR"
    ],
    "channels": [
        "level2",
        "heartbeat",
        {
            "name": "ticker",
            "product_ids": [
                "ETH-BTC",
                "ETH-USD"
            ]
        }
    ]
}

From coinbase: {"type":"error","message":"channel is required"}

示例2:

To coinbase:
{
  "type": "subscribe",
  "channels": [{ "name": "heartbeat", "product_ids": ["ETH-EUR"] }]
}
From coinbase: {"type":"error","message":"channel is required"}

示例3:

To coinbase:
{
  "type": "subscribe",
  "channels": [{ "name": "status"}]
}
From coinbase: {"type":"error","message":"channel is required"}

基本上，我不能订阅任何频道。

问题>我在这里做错了什么？

谢谢

Answer 1

也许有些东西被缓存在你发送的不是你认为你要发送的东西的地方？因为它对我来说非常有效，这里。

以wss://ws-feed.exchange.coinbase.com作为url和

{
  "type": "subscribe",
  "channels": [{ "name": "status"}]
}

作为信息。
