If you are working with Python Requests library, you may encounter situations where you need to encode your request data or response data in UTF-8 format. UTF-8 is a character encoding that can represent any character in the Unicode standard, making it a popular choice for internationalization and localization of applications.
When you send data in a request using the Requests library, it is sent as bytes. If your data contains non-ASCII characters, you need to encode it in UTF-8 format before sending it. Here's an example:
import requests data = response = requests.post('http://example.com', data=data.encode('utf-8'))
In this example, we're sending a POST request to 'http://example.com' with a dictionary containing a name that contains a non-ASCII character. We encode the data using UTF-8 before sending it.
When you receive data in a response using the Requests library, it is received as bytes. If the response contains non-ASCII characters, you need to decode it from UTF-8 format into a string. Here's an example:
import requests response = requests.get('http://example.com') data = response.content.decode('utf-8')
In this example, we're sending a GET request to 'http://example.com'. When we receive the response, we decode the content from UTF-8 format into a string.
If you are frequently working with non-ASCII characters, you may want to use UTF-8 encoding by default for all requests and responses. You can do this by setting the 'charset' parameter in the 'Content-Type' header of your requests:
import requests headers = data = response = requests.post('http://example.com', headers=headers, json=data)
In this example, we're setting the 'charset' parameter to UTF-8 in the 'Content-Type' header. This tells the server that we are sending UTF-8 encoded data. The Requests library will automatically encode our data in UTF-8 format and set the correct headers in our request.
Similarly, when we receive a response, we can tell Requests to automatically decode the response data using UTF-8 by setting the 'encoding' parameter:
import requests response = requests.get('http://example.com') response.encoding = 'utf-8' data = response.text
In this example, we're setting the 'encoding' parameter to UTF-8, which tells Requests to automatically decode the response data using UTF-8.
