BatonHTTP 负载测试工具
Baton 是一个用 Go 编写的 HTTP 负载测试工具，目前支持 GET、POST、PUT 和 DELETE 请求。
安装
$ go get -u github.com/americanexpress/baton
使用
目前支持以下选项
-b string
Body (use instead of -f)
-c int
Number of concurrent requests (default 1)
-f string
File path to file to be used as the body (use instead of -b)
-i Ignore TLS/SSL certificate validation
-m string
HTTP Method (GET,POST,PUT,DELETE) (default "GET")
-o Supress output, no results will be printed to stdout
-r int
Number of requests (use instead of -t) (default 1)
-t int
Duration of testing in seconds (use instead of -r)
-u string
URL to run against
-w int
Number of seconds to wait before running test
-z string
Read requests from a file
下面是使用 10 个终端发送 200,000 个请求的基本示例：
$ baton -u http://localhost:8080/test -c 10 -r 200000
可以指定发送请求的时间(以秒为单位)，而不是请求的数量，Baton 会等收到所有响应之后才报告结果。
请求文件
如果从 -z filename指定加载请求的文件，文件必须为 CSV 格式。
<method>,<url>,[<body>],[<header-key>:<header-value>, ...]
...
可以在末尾有一个或多个标题，用 , 隔开，比如：
POST,http://localhost:8888,body,Accept: application/xml,Content-type: Secret
GET,http://localhost:8888,,,
