In order to visualise how download_file_from_server_endpoint works, we can reuse the server backend from the proof of concept that we can use jQuery to push a dynamically generated file to the web browser based on the user's input.

Using download_file_from_server_endpoint to download a file from a HTTP server endpoint via HTTP POST In addition, we had supplied server_endpoint as the url and data_dict as the POST variables for requests.post to construct and send the HTTP request to the server for a HTTP response.Īfter we had gotten the Response object, we save the file contents in the response just like the function that downloads the file via HTTP GET. In this case, we had used requests.post instead of requests.get to get a Response object. Response = requests.post(url=server_endpoint, data=data_dict)Īs shown above, the download_file_from_server_endpoint function now accepts a server endpoint, a local file path, and a data dictionary. Given these points, we can create a Python 3 function that downloads a file from a HTTP server endpoint via HTTP POST:ĭef download_file_from_server_endpoint(server_endpoint, local_file_path, data_dict): Python 3 function that downloads a file from a HTTP server endpoint via HTTP POST

Construct the HTTP POST request to send to the HTTP server.

In such a situation, HTTP POST is a more appropriate HTTP method to use for downloading the file.Īs with HTTP GET, downloading of a file from the HTTP server via HTTP POST consists of the following steps:

There could be cases where the client need to supply some information to the HTTP server in order to download a file. Downloading a file HTTP from a HTTP server endpoint via HTTP POST For example, if we want to download Techcoil's logo, we can call the download_file_from_server_endpoint function as follows:ĭownload_file_from_server_endpoint('', 'logo.png')Īfter the function call completes, you should find Techcoil's logo in the same directory as the Python script if your computer is connected to the Internet. Using download_file_from_server_endpoint to download a file from a HTTP server endpoint via HTTP GETĪfter we had defined the download_file_from_server_endpoint function, we can then use it to download a file from a HTTP server endpoint via HTTP GET. Inside the with statement, data is read from the HTTP response in 128-byte chunks and written to local_file.

#Python 3 install http.server code#

When the status code in the HTTP response is a 200 OK, a file handler is created to write binary data to the path specified by local_file_path. After the function is called, it first uses requests.get to get a Response object. With open(local_file_path, 'wb') as local_file:įor chunk in er_content(chunk_size=128):Īs shown above, the download_file_from_server_endpoint function expects a server endpoint and a local file path as input. # Write the file contents in the response to a file specified by local_file_path # Send HTTP GET request to server and attempt to receive a response Given these points, we can create a Python 3 function that downloads a file from a HTTP server endpoint via HTTP GET:ĭef download_file_from_server_endpoint(server_endpoint, local_file_path): Python 3 function that downloads a file from a HTTP server endpoint via HTTP GET Save the contents of the file from HTTP Response to a local file.Send the HTTP request and receive the HTTP Response from the HTTP server.Construct the HTTP GET request to send to the HTTP server.

Generally, downloading a file from a HTTP server endpoint via HTTP GET consists of the following steps: Downloading a file from a HTTP server endpoint via HTTP GET In this post, let's see how we can download a file via HTTP POST and HTTP GET.

#Python 3 install http.server how to#

Previously, we discussed how to upload a file and some data through HTTP multipart in Python 3 using the 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.
