背景

在压测时，应用locust + boomer，须要配置python和go环境，略微有点麻烦。每次接口压测，都须要手动编写go脚本。因而想做对boomer做一个封装，能够疾速的实现这些需要，须要反对单接口 + 动静读取csv，curl命令

启动Locust-master

# run locust master
docker run --name locust-master -it -d -p 8089:8089 -p 5557:5557 rikasai/locust-master:latest

Boomer

调试模式启动boomer

$ docker run rikasai/boomer:latest --run-tasks worker -master-host=10.0.20.16 --url='http://httpbin.org/post' --method=POST --content-type="application/json"  --raw-data='{"ids": [123,234]}'
--verbose 1
2022/05/17 13:30:44 /usr/src/app/boomer_fasthttp.go:295: Fasthttp is running with these args:

2022/05/17 13:30:44 /usr/src/app/boomer_fasthttp.go:211: resp: {
  "args": {},
  "data": "{\"ids\": [123,234]}",
  "files": {},
  "form": {},
  "headers": {
    "Content-Length": "18",
    "Content-Type": "application/json",
    "Host": "httpbin.org",
    "User-Agent": "fasthttp",
    "X-Amzn-Trace-Id": "Root=1-6283a384-7d87389417a84df642d87a91"
  },
  "json": {
    "ids": [
      123,
      234
    ]
  },
  "url": "http://httpbin.org/post"
}

参数阐明

docker run rikasai/boomer:latest， 启动一个容器

–run-tasks worker,调试模式，固定写法

-master-host=10.0.20.16，指定locust-master的ip

–url=’http://httpbin.org/post’，申请url

–method=POST，申请办法

–content-type=”application/json”

–raw-data='{“ids”: [123,234]}’

–verbose 1，打印响应后果

locust worker模式启动

get申请

# 10.0.20.16 is master ip addr
# 5557 is default port
docker run rikasai/boomer:latest -master-host=10.0.20.16 -master-port=5557 --url='http://httpbin.org/get?a=123' --method=GET

post申请

docker run rikasai/boomer:latest -master-host=10.0.20.16 --url='http://httpbin.org/post' --method=POST --content-type="application/json"  --raw-data='{"ids": [123,234]}'

指定申请头

docker run rikasai/boomer:latest --run-tasks worker -master-host=10.0.20.16 --url='http://httpbin.org/post' --method=POST --content-type="application/json"  --raw-data='{"ids": [123,234]}'  --json-headers='{"User-Agent": "python-requests/2.22.0"}'

间接应用curl命令

docker run rikasai/boomer:latest --run-tasks worker -master-host=10.0.20.16 --curl="curl --location --request POST 'http://httpbin.org/post' \ --header 'Content-Type: application/json' \ --data-raw '{ "string": "hello,boomer" }'"

动静读取csv

docker run -d --name boomer -v /root/data/data.csv:/app/data.csv rikasai/boomer:latest  -master-host=10.0.20.16 --url=http://httpbin.org/post  --method=POST --content-type="application/json"  --raw-data='{"a": "$a", "b": "$b"}'  --replace-str-index='{"$a":0,"$b":1,"$c":2}' --json-value-type "int" --verbose 1

参数阐明

-d，后盾模式启动容器

–name boomer，指定容器的名字叫boomer，能够随便起，不重名就行

-v /root/data/data.csv:/app/data.csv，把宿主机的csv文件挂载到容器里，/root/data/data.csv是宿主机文件门路，/app/data.csv是容器里固定门路

–raw-data='{“a”: “$a”, “b”: “$b”}’，$a是取变量a，$b是取变量b

–replace-str-index='{“$a”:0,”$b”:1,”$c”:2}’，把csv中每一行着的第0值赋给$a,第1个值赋给$b,第2个赋给$c

–json-value-type “int” 指–raw-data中变量的值类型是int类型

/root/data/data.csv内容是：

1,2,3
3,4,5
4,5,6
455,56,633

申请log

2022/05/17 14:37:56 /usr/src/app/boomer_fasthttp.go:211: resp: {
  "args": {},
  "data": "{\"a\":1,\"b\":2}",
  "files": {},
  "form": {},
  "headers": {
    "Content-Length": "13",
    "Content-Type": "application/json",
    "Host": "httpbin.org",
    "User-Agent": "fasthttp",
    "X-Amzn-Trace-Id": "Root=1-6283b344-2ec1715202778cff233df950"
  },
  "json": {
    "a": 1,
    "b": 2
  },
  "url": "http://httpbin.org/post"
}

2022/05/17 14:37:56 /usr/src/app/boomer_fasthttp.go:211: resp: {
  "args": {},
  "data": "{\"a\":4,\"b\":5}",
  "files": {},
  "form": {},
  "headers": {
    "Content-Length": "13",
    "Content-Type": "application/json",
    "Host": "httpbin.org",
    "User-Agent": "fasthttp",
    "X-Amzn-Trace-Id": "Root=1-6283b344-155b24075acdcb214e963d51"
  },
  "json": {
    "a": 4,
    "b": 5
  },
  "url": "http://httpbin.org/post"
}

–json-value-type阐明

以--raw-data='{"a": "$a", "b": "$b"}'

csv内容是

1,2,3
3,4,5
4,5,6
455,56,633

• –json-value-type=intArray，申请后果是

  {
      "a": [
          3
      ],
      "b": [
          4
      ]
  }

• –json-value-type=string，申请后果是

  {
      "a": "3",
      "b": "4"
  }

• –json-value-type=interface，申请后果是

  csv内容是

  3,4,5
  aa,bb,cc

  先尝试转换成int类型，转换成胜利就是用int值，不胜利就是用原始值

  3,4,5转换成

  {
      "a": 3,
      "b": 4
  }

  aa,bb,cc转换成int不胜利，应用原始值

  {
      "a": "aa",
      "b": "bb"
  }

• 不反对深层json,这里的$b是不反对的。

  {
      "a":{
              "b": "$b"
      }
  }

目前动静替换并不完满，只能是一层json和body。后续再优化一波~
