DigitalOcean Functions, Python Runtime: HTTP Method

Does anyone know how a DigitalOcean Functions serverless implementation (running in Python) is supposed to know what HTTP method (e.g GET, POST, PUT, etc) was used to invoke it? The documentation is exceptionally vague and none of the samples appear to make use of HTTP methods

Hi there,

I believe that you should be able to just use the function arguments, for example:

function main(array $args) : array
    return ["body" => $args];

The following function should contain all of your required data, if you were to make a POST request you would get the following response:

  • Request example:
curl -X POST https://your_function_host_here -H "Content-Type: application/json"  -d '{"name": "Bobby"}'
  • You would get the following response:
  "__ow_headers": {
    "accept": "*/*",
    "accept-encoding": "gzip",
    "cdn-loop": "cloudflare",
    "cf-connecting-ip": "",
    "cf-ipcountry": "US",
    "cf-ray": "someidhere-SOF",
    "cf-visitor": "{\"scheme\":\"https\"}",
    "content-type": "application/json",
    "host": "ccontroller",
    "user-agent": "curl/7.79.1",
    "x-forwarded-for": "",
    "x-forwarded-proto": "https",
    "x-request-id": "some_request_here"
  "__ow_method": "post",
  "__ow_path": "",
  "name": "Bobby"

The "__ow_method": "post", indicates that the function was invoked with a POST method.

So, let’s say you wanted to access the name value only, you could do the following:

function main(array $args) : array
    $name = $args["name"] ?? "stranger";
    $greeting = "Hello $name!";
    echo $greeting;
    return ["body" => $greeting];

Hope that this helps.
