Locust + Boomer In Docker

原文由花菜发表于TesterHome社区，点击原文链接可与作者直接交流。

在压测时，使用locust + boomer，需要配置python和go环境，稍微有点麻烦。每次接口压测，都需要手动编写go脚本。因此想做对boomer做一个封装，可以快速的完成这些需求，需要支持单接口 + 动态读取csv，curl命令

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

$ 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]}'

参数说明

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’，请求url

–method=POST，请求方法

–content-type=“application/json”

–raw-data=‘{“ids”: [123,234]}’

–verbose 1，打印响应结果

# 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

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]}'

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"}'

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" }'"

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

参数说明

-d，后台模式启动容器

–name boomer，指定容器的名字叫boomer，可以随意起，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是宿主机文件路径，/app/data.csv是容器里固定路径

–raw-data=‘{“a”: “ a " , " b " : " a", "b": " a","b":"b”}’， a 是 取 变 量 a ， a是取变量a， a是取变量a，b是取变量b

–replace-str-index='{“ a " : 0 , " a":0," a":0,"b”:1,"KaTeX parse error: Expected 'EOF', got '}' at position 5: c":2}̲'，把csv中每一行着的第0值…a,第1个值赋给 b , 第 2 个 赋 给 b,第2个赋给 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

请求log

  },
  "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"
}

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，请求结果是

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

• –json-value-type=string，请求结果是

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

• –json-value-type=interface，请求结果是

  csv内容是

  3,4,5
  aa,bb,cc
  

  先尝试转换成int类型，转换成成功就是用int值，不成功就是用原始值

  3,4,5转换成

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

  aa,bb,cc转换成int不成功，使用原始值

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

• 不支持深层json,这里的$b是不支持的。

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

目前动态替换并不完美，只能是一层json和body。后续再优化一波~
