Bash script curl
提问by tech_enthusiast
#!/bin/bash
read -p 'Username: ' uservar
read -p 'Password: ' passvar
cacheVariable1="\"Content-Type:application/json"\"
cacheVariable2="\"Cache-Control:no-cache"\"
parametersVariable="'{\"username\":\"$uservar\",\"password\":\"$passvar\"}'"
echo $parametersVariable
echo $cacheVariable1 $cacheVariable2
websiteVariable="https://example.com/session"
echo $websiteVariable
entireURL="curl -X POST -H "$cacheVariable1" -H "$cacheVariable2" -d "$parametersVariable" "$websiteVariable""
echo "Entire URL IS: $entireURL"
result=`$entireURL`
echo "$result"
I want my script like this: curl -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{"username":"[email protected]", "password":"Password123"}' "https://example.com/session"
我想要这样的脚本： curl -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{"username":"[email protected]", "密码":"Password123"}' " https://example.com/session"
Entire URL IS: curl -H "Content-Type:application/json" -H "Cache-Control:no-cache" -d '{"username":"zzzzzz","password":"azzzsass"}' https://cloud.tenable.com/session
整个 URL 是： curl -H "Content-Type:application/json" -H "Cache-Control:no-cache" -d '{"username":"zzzzzz","password":"azzzsass"}' https: //cloud.tenable.com/session
But it does not execute in the bash. It gives me this error:
但它不会在 bash 中执行。它给了我这个错误：
{"statusCode":400,"error":"Bad Request","message":"child \"username\" fails because [\"username\" is required]","validation":{"source":"payload","keys":["username"]}}
But it does not work. Can anyone help me?
但它不起作用。谁能帮我？

I solved it on my own. Everything was correct, except for executing as eval $entireURL. Because A command embedded within a parenthesis runs as a sub-shell so my environment variables were missing.
我自己解决了。一切都是正确的，除了作为 eval $entireURL 执行。因为括号内嵌入的命令作为子shell运行，所以我的环境变量丢失了。
