如何格式化 websocket 请求? [英] How do I format a websocket request?

问题描述

我正在尝试用 Python 创建一个应用程序，当狗狗币地址的余额发生变化时，它会为 GPIO 端口供电.我正在使用 websocket API here 和 这个 websocket 客户端.

I'm trying to create an application in Python that powers a GPIO port when the balance of a Dogecoin address changes. I'm using the websocket API here and this websocket client.

我的代码如下所示:

from websocket import create_connection
ws = create_connection("wss://ws.dogechain.info/inv")
ws.send("op":"addr_sub", "addr":"dogecoin_address")
result =  ws.recv()
print (result)
ws.close()

这显然不是最终代码，但我只是想看看我是否能够连接到 websocket 并获得任何类型的响应.当我运行该代码时，它会因为请求中的冒号而引发错误.我不知道我应该如何格式化它才不会抛出错误.

It's obviously not the final code, but I just wanted to see if I'm even able to connect to the websocket and get any kind of response. When I run that code, it throws errors because of the colons in the request. I don't know what way I should format it that it won't throw an error.

推荐答案

我猜 API 需要 JSON 数据.你可以这样:

I'm guessing that the API wants JSON data. You can get that like so:

import json
from websocket import create_connection
ws = create_connection("wss://ws.dogechain.info/inv")
ws.send(json.dumps({"op":"addr_sub", "addr":"dogecoin_address"}))
result =  ws.recv()
print (result)
ws.close()
