The key is the name of the form field that accepts the file. We'll also save the response in a variable, write the following code: test_response = requests.post(test_url, files = ) We need two arguments to make this work: the URL of the server and files property. We'll use the post() method of the requests library to upload the file. We now have everything to make the request. Let's create a variable that stores the URL we'll post our files to: test_url = '' This API allows developers to test their HTTP requests. If the file is not read in bytes mode, the library may get an incorrect value for Content-Length, which would cause errors during file submission.įor this tutorial, we'll make requests to the free httpbin service. The requests library typically determines the Content-Length header, which is a value in bytes. Note: it's important to read the file in binary mode. Īctivate the virtual environment so that we would no longer impact the global Python installation: While not necessary, it's recommended that you install libraries in a virtual environment: $ python3 -m venv.

The first thing we need to do is install our the request library in our workspace.

To follow along, create three files called my_file.txt, my_file_2.txt and my_file_3.txt. This tutorial covers how to send the files, we're not concerned about how they're created. Uploading a Single File with Python's Requests Library Last but not least, we upload multiple files in one request. Next, we will cover how to upload a single file using the requests package. The article will start by covering the requests library and the post() function signature. In this tutorial, we will take a look at how to upload files using Python's requests library. It's also popular for interacting with servers! The library makes it easy to upload data in a popular format like JSON, but also makes it easy to upload files as well. The requests library is one of the most popular Python packages as it's heavily used in web scraping. Python is supported by many libraries which simplify data transfer over HTTP.
