To use python io.open_code, you can follow the example provided in the context where requests library is utilized to send and receive values. Below is a detailed guide on how to implement it:

1. Import the requests library:
“`python
import requests
“`

2. Define a function to set camera values:
“`python
def set_camera_value(URL):
try:
response = requests.get(URL)
if response.status_code == 200:
print(“SET parameter Complete”)
return True
else:
print(f”SET Parameter FAIL. Status code: {response.status_code}”)
return False
except Exception as e:
print(f”set_camera_value Error: {e}”)
return False
“`

3. Define a function to get camera values:
“`python
def get_camera_value(URL):
try:
response = requests.get(URL)
root = ET.fromstring(response.content)
if response.status_code == 200:
get_value = root.find(“.//xsi:value”, namespaces={“xsi”: “http://www.w3.org/2001/XMLSchema-instance”}).text
return get_value
else:
print(f”Request failed with status code: {response.status_code}”)
return None
except Exception as e:
print(f”get_camera_value Error : {e}”)
return None
“`

4. Example of how to use the functions:
“`python
# Set camera value
set_camera_value(“http://192.168.0.178/prod/res/image/sysimg/measureFuncs/spot/1/active?set=false”)

# Get camera value
value = get_camera_value(“http://192.168.0.178/prod/res/image/sysimg/measureFuncs/spot/1/value”)
print(f”Received value: {value}”)
“`

This example demonstrates how to use the requests library in Python to send and receive values from a camera. By following this guide, you can effectively interact with the camera’s API to control various functionalities.
