Description
Hello,
The following code
```julia
# Import the WebSockets library for WebSocket communication and JSON for data handling
using WebSockets
using JSON
# Function to fetch data from Binance WebSocket API
function fetch_binance_data(url::String)
# Open a WebSocket connection to the provided URL
WebSockets.open(url) do ws
# Loop to continuously read incoming messages from WebSocket
while true
try
# Read a single message from the WebSocket connection
msg = read(ws, String)
# Parse the JSON message into a Julia dictionary
data = JSON.parse(msg)
# Print the received data (you may replace this with other processing code)
println(data)
catch e
# Print any errors encountered while reading/parsing data
println("Error encountered: $e")
# Break out of the loop on error to avoid infinite error printing
break
end
end
end
end
# Binance WebSocket URL to fetch depth data for ADA/USDT and BTC/USDT pairs
url = "wss://stream.binance.com:9443/stream?streams=adausdt@depth20@100ms/btcusdt@depth20@100ms"
# Call the function to initiate WebSocket data fetching
fetch_binance_data(url)
```
raises
```
Error encountered: ErrorException("OpenSSL.SSLStream does not support byte I/O")
```
I have no idea why?
Best regards
PS :
```julia
# Import the HTTP library for WebSocket communication and JSON for data handling
using HTTP
using JSON
# Function to fetch data from Binance WebSocket API
function fetch_binance_data(url::String)
# Open a WebSocket connection to the provided URL
HTTP.WebSockets.open(url) do ws
# Loop to continuously read incoming messages from WebSocket
for msg in ws
# Parse the JSON message into a Julia dictionary
data = JSON.parse(msg)
# Print the received data (you may replace this with other processing code)
println(data)
end
end
end
# Binance WebSocket URL to fetch depth data for ADA/USDT and BTC/USDT pairs
url = "wss://stream.binance.com:9443/stream?streams=adausdt@depth20@100ms/btcusdt@depth20@100ms"
# Call the function to initiate WebSocket data fetching
fetch_binance_data(url)
```
is a workaround
