httpx VS AIOHTTP

Using the createSession, deleteSession endpoints and httpx, we can create a session for API interaction.

I've mostly ditched requests in favour of httpx these days. https://www.python-httpx.org

Now that your environment is set up, you’re going to need to install the HTTPX library for making requests, both asynchronous and synchronous which we will compare. Install this with the following command after activating your virtual environment:

Now time to code the implementation, as I wanted to both read from and write to ffmpeg concurrently, so this is going to be an asyncio application. The http client library we are using this time is httpx, which has a method to fetch download in smaller batches:

The concept of a Client in httpx is analogous to a Session in requests. However, httpx.Client is more powerful and efficient. You can read the article from the httpx documentation, to learn more about httpx.Client.

Let's look at a simple code example. This will work for requests, httpx, and aiohttp with a clean installation and no extensions.

For reference, it's a butterfly, not a moth.

Very cool, first I'm hearing of httpx https://www.python-httpx.org/

I think most people would start with trying out requests or something for this kind of work, I'm guessing that didn't work out? You've got a star from me.

To access 10 different commands at the same time, that is tricky but definitely doable.

First thing that comes to mind, you can use aliases.

To keep it simple, lets use 3 examples instead of 10: harlequin (this project), pgcli (https://www.pgcli.com/) and httpx (https://www.python-httpx.org/)

Setup a main home for all your venvs:

> AIOHTTP: The Python int constructor is used to parse Content-Lengths and chunk-sizes, so _, +, and - are misinterpreted.

Fun. I believe the fix is incomplete here[1]. Python's int() constructor accepts integers comprised of any unicode numeral, for example, int("٦٦٦") == 666, and "٦٦٦".isdecimal() == True.

aiohttp

If you want speed, I would try to rewrite everything using an asynchronous library like aiohttp.

requests does not support async out-of-the-box, so we will use aiohttp to avoid complications. requests can do the job, and there is no substantial performance difference. But the code is more readable using aiohttp.

I'm using aiohttp to build an API server that sends TCP requests off to a seperate server. The module that sends the TCP requests is synchronous and a black box for my purposes. So my problem is that these requests are blocking the entire API. I need a way to wrap the module requests in an asynchronous coroutine that won't block the rest of the API.

aiohttp - Everything that I need and nothing that I don't.

Use aiohttp to download the content of each page of lists. As of this Code Review post, this is the only step we execute.
