如何在一系列服务器IP(URL)上执行相同的curl请求 [英] How to execute the same curl request on a sequence of server IPs (URLs)

问题描述

命令

curl -v -H "Accept: application/json" -H "Content-type: application/json" \
        -X POST -d '{"test": "some data"}' http://XX.XX.X.001:8080/services/test

我想在不同的服务器(IP地址)上执行上述相同的curl命令.有什么方法或CURL命令，以便我可以在所有服务器上执行此服务，而不是每次都手动更改IP地址吗?

I want to execute the above same curl command on different servers (IP addresses). Is there any way or CURL command so I can execute this service on all servers, instead of changing the IP address every time manually?

我以某种顺序拥有服务器IP，例如

I have servers IP in some sequence, e.g.

http://XX.XX.X.002:8080/services/test
http://XX.XX.X.003:8080/services/test
...

推荐答案

您可以使用Shell的括号扩展，例如{2..15}表示2,3,4,...,15:

You can either use shell's brace expansion in bash, e.g. {2..15} for 2,3,4,...,15:

curl ... http://x.x.x.{2..15}:8080/services/test

或curl的字母数字系列[]运算符在网址部分(请注意双引号):

or, curl's alphanumeric series [] operator in the URL part (notice the double-quotes):

curl ... "http://x.x.x.[2-15]:8080/services/test"

或者，您可以使用算术for循环:

Alternatively, you can use arithmetic for loop:

for ((i=2; i<=15; i++)); do
    curl ... "http://x.x.x.$i:8080/services/test"
done
