decryptr/api
Dockerfile and plumber to start the api.
Usage
To serve the API on http://localhost:80 with no load balancing, run the command below:
docker build -t api .
docker run -p 80:80 api
Adding a new key
One can add new keys using the key_generator function found in key-generator.R.
Keys are a sequence of 64 random generated elements and their hash is saved in the keys.yaml file. The generated key can only be seen once.
To generate a new key you need to run:
source("key-generator.R")
key_generator("name-of-the-endpoint")
The function will make necessary modifications to keys.yaml. They generated key will be printed to the console. Note The key is printed only once.
Updating the endpoint
On shell, type:
docker build -t dfalbel/api .
docker push dfalbel/api
gcloud compute instances create-with-container decryptr \
--project=decryptr-196601 \
--container-image dfalbel/api \
--machine-type g1-small \
--tags http-server \
--address 104.197.127.86 \
--metadata startup-script='#! /bin/bash
sudo iptables -w -A INPUT -p tcp --dport 80 -j ACCEPT
EOF
'
You must have gcloud CLI installed.
Using from R
You can use the API from with the following chunk of code:
library(magrittr)
# parameters
arq <- "https://decryptr.netlify.com/img/sample-captcha.png"
key <- "your-api-key"
# converting the image to base64
img <- arq %>%
readr::read_file_raw() %>%
base64enc::base64encode()
# post request
res <- httr::POST(
"https://decryptr.now.sh/rfb",
body = list(
img = img,
key = key
),
encode = "json"
)
httr::content(res)
