While working on a project that produces JSON and sends it to a server using an HTTP POST request, I found it sometimes inconvenient to start the server every time I needed it. Most of the time, unless I was working on the server code itself, I just wanted to see the raw request data. I learned that the nc utility (AKA Netcat) could do just that.

However, using nc the way others explained it didn't work well for my purposes. It turns out that it shouldn't be run in the background, as was suggested, and it should give a proper HTTP response to satisfy the client. I came up with this solution:

while [[ 1 ]]; do printf 'HTTP/1.1 200 OK\n\n' | nc -l localhost 8000; printf '\n\n= = = = = %s = = = = =\n\n' "$(date)"; done

It's helpful to run this in a shell in a separate window. As new requests are received, they will be seen scrolling up the display.

Copy Bitbucket repo to GitHub

Whenever possible, use GH's "Import repository" feature.

The import feature doesn't always work, though. In my experience, I tried to import a repo and it failed with a generic message. I had to contact GH support to ask for help. They told me my repo had a large file (>100MB), which couldn't be added to GH directly. I had to either remove the file or store it in GH LFS. In this case, one of the CLI methods below are needed:

CLI: Copy the master branch only (OK)

Intro

The plan is to create a pair of executables (ngrok and ngrokd) that are connected with a self-signed SSL cert. Since the client and server executables are paired, you won't be able to use any other ngrok to connect to this ngrokd, and vice versa.

DNS

Add two DNS records: one for the base domain and one for the wildcard domain. For example, if your base domain is domain.com, you'll need a record for that and for *.domain.com.

Two ways to do it, but only worked for me so I'll put it first and the second for reference:

$ openssl pkcs12 -export -in hostname.crt -inkey hostname.key -out hostname.p12
$ openssl pkcs12 -in hostname.p12 -nodes -out hostname.pem

Other options for this method in comments below:

# Note, the -certfile root.crt appends all CA certs to the export,
# I've never needed these so it's optional for my personal steps

$ openssl pkcs12 -export -in hostname.crt -inkey hostname.key -certfile root.crt -out hostname.p12

	 * Problem: `DateTime::getTimestamp` returns **_`int`_**! Calculations such as the following
	 * are incorrect if the `DateTime` object includes fractions of seconds:
	 *
	 * ```php
	 * $durationSeconds = strval($endTime->getTimestamp() - $startTimestamp);
	 * ```
	 *
	 * `DateTime::diff` can subtract properly, but only under PHP 7.1.  (Curiously,
	 * `DateTime::getTimestamp` still returns `int` under PHP 7.1!)
