See body-content-workflow and anycodings_stream er_content for further anycodings_stream reference. Note that the number of bytes returned anycodings_stream using iter_content is not exactly the anycodings_stream chunk_size it's expected to be a random anycodings_stream number that is often far bigger, and is anycodings_stream expected to be different in every anycodings_stream iteration. # If you have chunk encoded response uncomment if With requests.get(url, stream=True) as r:įor chunk in r.iter_content(chunk_size=8192):
# Or do anything shown above using `uncompressed` instead of `response`.With the following streaming code, the anycodings_stream Python memory usage is restricted anycodings_stream regardless of the size of the downloaded anycodings_stream file: def download_file(url): With gzip.GzipFile(fileobj=response) as uncompressed:įile_header = uncompressed.read(64) # a `bytes` object # Read the first 64 bytes of the file inside the. gz (and maybe other formats) compressed data on the fly, but such an operation probably requires the HTTP server to support random access to the file. But this works well only for small files. If this seems too complicated, you may want to go simpler and store the whole download in a bytes object and then write it to a file. With (url) as response, open(file_name, wb) as out_file: So the most correct way to do this would be to use the function to return a file-like object that represents an HTTP response and copy it to a real file using pyfileobj. tmp/tmpb48zma.txt) in the `file_name` variable:įile_name, headers = (url)īut keep in mind that urlretrieve is considered legacy and might become deprecated (not sure why, though). # Download the file from `url`, save it in a temporary directory and get the # Download the file from `url` and save it locally under `file_name`: The easiest way to download and save a file is to use the function: import urllib.request
Text = code(utf-8) # a `str` this step cant be used if data is binary If you want to obtain the contents of a web page into a variable, just read the response of : import urllib.requestĭata = response.read() # a `bytes` object
