Hi,
What is the best way to get the JSON content of a POST request in a serverless function. The traditional way does not work. (traditional function for this is file_get_contents(‘php://input’))
Has anyone done this successfully? TIA

Hi there,
I believe that you should be able to just use the function arguments, for example:
<?php
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:
curl -X POST https://your_function_host_here -H "Content-Type: application/json" -d '{"name": "Bobby"}'
{
"__ow_headers": {
"accept": "*/*",
"accept-encoding": "gzip",
"cdn-loop": "cloudflare",
"cf-connecting-ip": "123.123.123.123",
"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": "123.123.123.123",
"x-forwarded-proto": "https",
"x-request-id": "some_request_here"
},
"__ow_method": "post",
"__ow_path": "",
"name": "Bobby"
}
So, let’s say you wanted to access the name value only, you could do the following:
<?php
function main(array $args) : array
{
$name = $args["name"] ?? "stranger";
$greeting = "Hello $name!";
echo $greeting;
return ["body" => $greeting];
}
Hope that this helps.
Best,
Bobby
