從 HTTP 回復返回的 JSON 中提取 UUID 值

我正在嘗試在 shellscript 中製作一個小腳本，該腳本從響應中獲取一個 serviceUuid 並使用它。我只是在名為 final.txt 的文件上列印伺服器響應現在我需要提取“serviceUuid”之後的值：”

這是腳本：

uuid=$(curl   -X POST -H "ACCEPT-LANGUAGE:en"   -H "Content-Type: application/json"   -H "Accept: application/json" -d  {"username":"HereThereIsTheUsername"}  Here there is the url )

echo $uuid >> final.txt

這是回應：

{"status":{"code":"STATUS_OK","message":"ServiceUUID sent successfully via..."},"body":{"data":{"userApps":{},"username":"HereTheUsername","fullName":"NameOfTheAccountPossessor","lang":"sq","blocked":false,"lastLogin":"2016-10-10T17:19:22","passwordResetUuid":"6147dc32-b72e-450a-8084-2fdb5319a931","userAccessLevel":5,"countDownSeconds":0,"serviceUuid":"7260276c-5c3f-41d3-9329-3603acecb7e5","userAttributes":{},"labelMap":{},"id":"APPUSER00000012","someLabel":"NameOfTheOrganisation"}}}

那麼有人可以幫我提取價值嗎？

現在我需要在“serviceUuid”之後提取值

因此，如果變數$uuid包含以下內容：

echo "$uuid"
{"status":{"code":"STATUS_OK","message":"ServiceUUID sent successfully via..."},"body":{"data":{"userApps":{},"username":"HereTheUsername","fullName":"NameOfTheAccountPossessor","lang":"sq","blocked":false,"lastLogin":"2016-10-10T17:19:22","passwordResetUuid":"6147dc32-b72e-450a-8084-2fdb5319a931","userAccessLevel":5,"countDownSeconds":0,"serviceUuid":"7260276c-5c3f-41d3-9329-3603acecb7e5","userAttributes":{},"labelMap":{},"id":"APPUSER00000012","someLabel":"NameOfTheOrganisation"}}}

…而您只想要serviceUuid價值，我會這樣做：

echo "$uuid" | sed -nE 's/.*"serviceUuid":"(.*)","user.*/\1/p'

在您的情況下，它看起來像：

echo "$uuid" | sed -nE 's/.*"serviceUuid":"(.*)","user.*/\1/p' >> final.txt

…將其附加到文件中final.txt

sed --version
sed (GNU sed) 4.2.2

jq是一個 JSON 解析工具。你可以這樣做：

uuid=$(curl ...)
service_uuid=$(jq -r '.body.data.serviceUuid' <<<"$uuid")
echo "$service_uuid"
