Very simple, here is the code example:
# This code is only used for learning and research interfaces, it just provides a reference
require 'typhoeus'
# Send SMS interface URL, if not necessary, this parameter does not need to be modified
api_send_url="http://222.73.117.156/msg/HttpBatchSendSM"
# Create a blue account, replace it with your own account
account="xxxxxx"
# Create a blue password, replace it with your own password
pswd="xxxxxx"
body={account:account,pswd:pswd,mobile:"13800138000",msg:"Hello, your verification code is 1234",needstatus:"true"}
resp=Typhoeus::Request.post(api_send_url,body:body)
puts resp.body
