Python Requests Post Stream

If you are writing a Python program and want to interact with HTTP URLs, you can use the Python Requests library. The requests library provides a fast and easy way to interact with web services.

What is POST Method?

POST method is used to submit an entity to the specified resource, often causing a change in state or side effects on the server.

What is Streaming?

Streaming means sending data in a continuous flow. It is used when sending large amounts of data so that the recipient can start processing the data before the entire message has been transmitted.

How to use Python Requests with POST method and Streaming?

You can use the "requests.post" method along with the "stream" parameter to make a POST request with streaming. Here is an example:


import requests

response = requests.post('http://example.com/stream', stream=True, data={'key': 'value'})

for chunk in response.iter_content(chunk_size=1024):
    if chunk:
        print(chunk)
  • The 'http://example.com/stream' URL is where the data will be sent.
  • The 'stream=True' parameter tells requests to use streaming.
  • The 'data={'key': 'value'}' parameter sends data along with request.
  • The 'chunk_size=1024' parameter specifies the size of data chunks to be received.

In the above example, we are iterating over the response content in chunks of size 1024 bytes using the "iter_content" method. This method returns chunks of data as it is downloaded from the server.

Alternatively, you can also use the "iter_lines" method to iterate over the response content line by line:


import requests

response = requests.post('http://example.com/stream', stream=True, data={'key': 'value'})

for line in response.iter_lines():
    if line:
        print(line)

In the above example, we are iterating over the response content line by line using the "iter_lines" method.

Conclusion

Python Requests is a powerful library that can be used to interact with web services. With the "stream" parameter, you can make POST requests with streaming and efficiently handle large amounts of data.
