API Test Menggunakan Curl dan Shell Script

Test API dengan Curl

Kali ini saya akan share cara test API dengan curl dan shell script.

Untuk API-nya, kita akan menggunakan API dari restfull-booker . Silahkan cek dokumentasinya sebelum mengikut tutorial ini.

Kita akan membuat tutorial ini seolah-olah seperti API “beneran”, untuk output dari curl akan kita buat “cantik” dengan menggunakan jq

1. Mendapatkan token untuk otentikasi

   curl -s -X POST \
   https://restful-booker.herokuapp.com/auth \
   -H 'Content-Type: application/json' \
   -d '{
   "username" : "admin",
   "password" : "password123"
   }' | jq
   

   

   Untuk mendapatkan value dari token saja gunakan (ini bakal kita gunakan nanti di shell script)

   curl -s -X POST \
   https://restful-booker.herokuapp.com/auth \
   -H 'Content-Type: application/json' \
   -d '{
   "username" : "admin",
   "password" : "password123"
   }' |  jq -r '.token'
   #outpunya hanya d4aebae5dd25ebd
   

2. Kita buat booking ID

   curl -s -X POST \
   https://restful-booker.herokuapp.com/booking \
   -H 'Content-Type: application/json' \
   -d '{
   "firstname" : "Anyong",
   "lastname" : "Haseo",
   "totalprice" : 111,
   "depositpaid" : true,
   "bookingdates" : {
       "checkin" : "2022-11-04",
       "checkout" : "2022-12-25"
   },
   "additionalneeds" : "Breakfast"
   }'
   

   

   Untuk mendapat booking id saja, gunakan

   curl -s -X POST \
   https://restful-booker.herokuapp.com/booking \
   -H 'Content-Type: application/json' \
   -d '{
   "firstname" : "Anyong",
   "lastname" : "Haseo",
   "totalprice" : 111,
   "depositpaid" : true,
   "bookingdates" : {
       "checkin" : "2022-11-04",
       "checkout" : "2022-12-25"
   },
   "additionalneeds" : "Breakfast"
   }' | jq -r '.bookingid'
   

3. Check booking ID (bookingid)

   curl -s -X GET \
   "https://restful-booker.herokuapp.com/booking/14153" | jq
   

   

4. Update booking ID, kita update “additional need” dari breakfast ke king size bed

   curl -s -X PUT \
   https://restful-booker.herokuapp.com/booking/1 \
   -H 'Content-Type: application/json' \
   -H 'Accept: application/json' \
   -H 'Cookie: token=abc123' \
   -d '{
   "firstname" : "Anyong",
   "lastname" : "Haseo",
   "totalprice" : 112,
   "depositpaid" : true,
   "bookingdates" : {
   "checkin" : "2022-11-04",
   "checkout" : "2022-12-25"
   },
   "additionalneeds" : "King Size Bed"
   }'
   

   

5. Delete booking ID

   curl -s -X DELETE \
   https://restful-booker.herokuapp.com/booking/14153 \
   -H 'Content-Type: application/json' \
   -H 'Cookie: token=d4aebae5dd25ebd'
   

   

Buat Otomatisasi dengan Shell Script

Buka editor kamu, copy script di bawah ini

#!/bin/bash

USER="admin"
PASS="password123"

BOOKING_FIRSTNAME="anyong"
BOOKING_LASTNAME="haseo"
BOOKING_TOTALPRICE="111"
BOOKING_DEPOSITPAID="true"
BOOKING_CHECKIN="2022-11-04"
BOOKING_CHECKOUT="2022-11-29"
BOOKING_ADDITIONALNEEDS="breakfast"
UPDATE_BOOKING_ADDITIONALNEEDS="king size bed"


#make json output using jo
JSON_AUTH=$( jo "username=$USER" "password=$PASS" )

JSON_BOOKING_DATA=$( jo -p "firstname=$BOOKING_FIRSTNAME" "lastname=$BOOKING_LASTNAME" \
            "totalprice=$BOOKING_TOTALPRICE" "depositpaid=$BOOKING_DEPOSITPAID" \
            "bookingdates[checkin]=$BOOKING_CHECKIN" "bookingdates[checkout]=$BOOKING_CHECKOUT" \
            "additionalneeds=$BOOKING_ADDITIONALNEEDS")

JSON_UPDATE_BOOKING_DATA=$( jo -p "firstname=$BOOKING_FIRSTNAME" "lastname=$BOOKING_LASTNAME" \
            "totalprice=$BOOKING_TOTALPRICE" "depositpaid=$BOOKING_DEPOSITPAID" \
            "bookingdates[checkin]=$BOOKING_CHECKIN" "bookingdates[checkout]=$BOOKING_CHECKOUT" \
            "additionalneeds=$UPDATE_BOOKING_ADDITIONALNEEDS")

#GET auth token
GET_TOKEN=`(curl -s -X POST \
    https://restful-booker.herokuapp.com/auth \
    -H 'Content-Type: application/json' \
    -d "$JSON_AUTH" | jq -r '.token')`

echo token: $GET_TOKEN

#GET bookingid
GET_BOOKING_ID=`(curl -s -X POST \
    "https://restful-booker.herokuapp.com/booking" \
    -H 'Content-Type: application/json' \
    -d "$JSON_BOOKING_DATA" \
    | jq -r '.bookingid')`

echo bookingid: $GET_BOOKING_ID

#GET booking data
GET_BOOKING_DATA=`(curl -s -X GET \
    "https://restful-booker.herokuapp.com/booking/$GET_BOOKING_ID" | jq)`

echo -e "booking data:\n $GET_BOOKING_DATA"

COOKIE_HEADER=(-H "Content-Type: application/json" -H "Cookie: token=${GET_TOKEN}" )

#UPDATE booking data
UPDATE_BOOKING_DATA=`(curl -s -X PUT \
    "https://restful-booker.herokuapp.com/booking/$GET_BOOKING_ID" \
    "${COOKIE_HEADER[@]}" \
    -d "$JSON_UPDATE_BOOKING_DATA")`

#GET updated booking data
GET_UPDATE_BOOKING_DATA=`(curl -s -X GET \
    "https://restful-booker.herokuapp.com/booking/$GET_BOOKING_ID" | jq)`

echo -e "update booking data:\n $GET_UPDATE_BOOKING_DATA"
# echo $JSON_TOKEN
# echo -e "$UPDATE_BOOKING_DATA"

# echo ${COOKIE_HEADER[@]}
# # echo ${HEADERS[@]}

#DELETE booking data
#try using URL in variable
#it was cleaner
URL="https://restful-booker.herokuapp.com/booking/$GET_BOOKING_ID"

curl "${COOKIE_HEADER[@]}" -X DELETE "$URL"
