【常用脚本记录2---压力测试脚本】

1.累计增加设备，尽量多增加设备

#!/bin/bash

#set -x

function rand(){
    min=$1
    max=$(($2-$min+1))
    num=$(date +%s%N)
    echo $(($num%$max+$min))
}

#login
tmp=`curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{"password": "password", "username": "apiuser"}' 
'https://192.168.23.43:8080/api/internal/login' --insecure  2>/dev/null`

token=`echo $tmp | sed 's/"/ /g' | awk '{print $4}'`
proFileID=$1
for i in $(seq $2)
do
  echo -n "."
  devEUI=$(rand 1000000000000000 9999999999999999)
  curl=`curl -k -X POST --header 'Accept: application/json' --header "Authorization: Bearer $token" -d "{"devEUI":"${devEUI}","profileID":"${proFileID}","applicationID":"1","appKey":"5572404c696e6b4c6f52613230313823"}"  'https://192.168.23.43:8080/api/urdevices'   2>/dev/null` 
done

echo "DONE"
exit 0

先从要连接的设备那边获取到 pro_id

root@ROUTER:~# postgres -u postgres -d loraserver_ns

查看当前设备的loraserver_ns的地址

将上面的device_profile_id作为脚本的第一个参数，第二个参数为要生成的数量
