RunPy limitations
Limitation: Unable to Open External URLs with urlopen in RunPy
When using the urlopen
function within a RunPy query, you may encounter an error when trying to open external URLs, such as https://api.baserow.io
. This limitation is due to the underlying framework used by RunPy, Pyodide, which has certain constraints and may not support all features available in a standard Python environment.
Solution: Using fetch function with JavaScript
To overcome this limitation, you can utilize the fetch
function from JavaScript, as Pyodide supports interoperability between Python and JavaScript. Here's an example of how to make an HTTP request using the fetch
function in a RunPy query:
from js import fetch
import json
async def push_data(url, data):
response = await fetch(
url,
method='POST',
headers=[
["Authorization", "Token <my_token>"],
["Content-Type", "application/json"]
],
body=data
)
reply = await response.json()
return reply
url = "https://api.baserow.io/api/database/rows/table/.../?user_field_names=true"
reply = await push_data(url, json.dumps(<my_data>))
reply
In the example above, the fetch
function is used to make an HTTP POST request to the specified URL. The Authorization
header is included to provide the necessary authentication token, and the request body is passed as JSON data.
By using the fetch
function and incorporating JavaScript interoperability, you can successfully make HTTP requests within a RunPy query in scenarios where urlopen
may encounter limitations.
It's important to note that the solution provided here assumes you have the necessary authorization token and data to push to the Baserow table. Adjust the code accordingly to fit your specific requirements.
