Download large file in python with requests - Stack Overflow
Nov 14, · How to download a file via HTTP POST and HTTP GET with Python 3 requests library When you are building a HTTP client with Python 3, you could be coding it to upload a file to a HTTP server or download a file from a HTTP server.. Previously, we discussed how to upload a file and some data through HTTP multipart in Python 3 using the requests library. By some reason it doesn't work this way. It still loads response into memory before save it to a file. UPDATE. If you need a small client (Python 2.x /3.x) which can download big files from FTP, you can find it here. It supports multithreading & reconnects (it does monitor connections) also it tunes socket params for the download task. Apr 17, · This post is about how to efficiently/correctly download files from URLs using Python. I will be using the god-send library requests for it. I will write about methods to correctly download binaries from URLs and set their filenames. Let's start with baby steps on how to download a file using requests --Author: Avi Aryan.
Python download file requests and save
I will be using the god-send library requests for it. I will write about methods to correctly download binaries from URLs and set their filenames. What do you think will happen if the above code is used to download it? If you said that a HTML page will be downloaded, you are spot on. This was one of the problems I faced in the Import module of Open Event where I had to download media from certain links.
When the URL linked to a python download file requests and save rather than a binary, I had to not download that file and just keep the link as is. To solve this, what I did was inspecting the headers of the URL. Headers usually contain a Content-Type parameter which tells us about the type of data the url is linking to. A naive way to do it will be. It works but is not the optimum way to do so as it involves downloading the file for checking the header.
So if the file is large, this will do nothing but waste bandwidth. I looked into the requests documentation and found a better way to do it. That way involved just fetching the headers of a url before actually downloading it. This allows us to skip python download file requests and save files which weren't meant to be downloaded.
To restrict download by file size, we can get the filesize from the Content-Length header and then do suitable comparisons. We can parse the url to get the filename. This will be give the filename in some cases correctly.
However, there are times when the filename information is not present in the url. In that case, the Content-Disposition header will contain the filename information. Here is how to fetch it.
The url-parsing code in conjuction with the above method to get filename from Content-Disposition header will work for most of the cases. Use them and test the results.
