Bash Shell Curl JSON 變量傳遞

Question

我試圖從 shell 腳本和命令行參數進行 CURL 調用。

url=$1
pg=$2
coockie=$3

curl '$url' -H 'sec-fetch-mode: cors' -H 'origin: $url' -H 'accept-encoding: gzip, deflate, br' -H 'accept-language: en-GB,en-US;q=0.9,en;q=0.8' -H 'user-agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 Safari/537.36' -H 'content-type: application/json;charset=UTF-8' -H 'accept: application/json, text/plain, */*' -H 'referer: $url' -H 'authority: recruiting.adp.com' -H '$cookie' -H 'sec-fetch-site: same-origin' --data-binary $'{"filters":[{"name":"country","label":"Country"},{"name":"state","label":"State"},{"name":"grp","label":"Job Type"},{"name":"ptitle","label":"Job"}],"results":{"pageTitle":"Search Results","zeroResultsMessage":"We\'re sorry but we have no job openings at this time that match your search criteria. Please try another search.","searchFailureMessage":"Oops\u0021 Something went wrong.  Search has encountered a problem. Try searching again","resultsFoundLabel":"results found","bookmarkText":"Bookmark This","pageSize":"100","sortOrder":"00001000","shareText":"Share","fields":[{"name":"ptitle","label":"Published Job Title"},{"name":"location","label":"Location"},{"name":"position","label":"Position"}]},"pagefilter":{"page": 3},"rl":"enUS"}' --compressed

回聲“$url $pg”

但是 "pagefilter":{"page": 3},"rl":"enUS"}' 在這個頁面屬性腳本中當它是一個數值時正在工作，但我希望它像 "pagefilter":{"page": "$page"},"rl":"enUS"}'

無法理解為什么它不起作用。 也嘗試轉義雙引號。

輸入類似於 /s.sh "URL" 3 1234

Answer 1

在大多數情況下，用雙引號/單引號/雙引號包裹你的變量"'"會有所幫助

page=3
curl -d'{"page":"'"$page"'"}' http://...

這將擴展到

curl -d'{"page":"3"}' http://...

或者只使用單/雙引號'"擴展為一個數字：

curl -d'{"page":'"$page"'}' http://...

將擴展到

curl '-d{"page":3}'

Answer 2

感謝@jschnnasse 嘗試使用 bash -x 並發現只有 '$pg' 取值 "pg" 、 "'$pg'" 和 '"$pg"' 不工作 以下代碼工作正常。

url=$1
pg=$2
coockie=$3

curl '$url' -H 'sec-fetch-mode: cors' -H 'origin: $url' -H 'accept-encoding: gzip, deflate, br' -H 'accept-language: en-GB,en-US;q=0.9,en;q=0.8' -H 'user-agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 Safari/537.36' -H 'content-type: application/json;charset=UTF-8' -H 'accept: application/json, text/plain, */*' -H 'referer: $url' -H 'authority: recruiting.adp.com' -H '$cookie' -H 'sec-fetch-site: same-origin' --data-binary $'{"filters":[{"name":"country","label":"Country"},{"name":"state","label":"State"},{"name":"grp","label":"Job Type"},{"name":"ptitle","label":"Job"}],"results":{"pageTitle":"Search Results","zeroResultsMessage":"We\'re sorry but we have no job openings at this time that match your search criteria. Please try another search.","searchFailureMessage":"Oops\u0021 Something went wrong.  Search has encountered a problem. Try searching again","resultsFoundLabel":"results found","bookmarkText":"Bookmark This","pageSize":"100","sortOrder":"00001000","shareText":"Share","fields":[{"name":"ptitle","label":"Published Job Title"},{"name":"location","label":"Location"},{"name":"position","label":"Position"}]},"pagefilter":{"page": '$pg'},"rl":"enUS"}' --compressed
