我正在尝试编写一个shell脚本,它将从URL获取一些json并解析json并提取字段。 这是到目前为止所做的。

#!/bin/bash

token=$(http POST :3000/signin/frontm user:='{"email": "sourav@frontm.com", "password": "Hello_789"}' | jq -r '.data.id_token')   
cred=$(http POST :3000/auth provider_name:frontm token:$token user:=@/tmp/user.json | jq '{ creds: .creds, userUuid: .user.userId }')

echo $cred
access=$(jq -r "'$cred'")
echo $access

所以echo $ cred的输出是一个json: 例如:

{ "creds": { "accessKeyId": "ASIAJPM3RDAZXEORAQ5Q", "secretAccessK
ey": "krg5GbU6gtQV+a5pz4ChL+ECVJm+wKogjglXOqr6", "sessionToken": "Ag

所以基本上我被困在这里..我如何进一步解析这个json in $ cred并且基本上想要进一步使用jq说accessKeyId?

1 个答案:

答案 0 :(得分:1)

我想知道变量$cred是否真的包含在67列中形成的字符串,但如果是这样,tr可能有助于删除换行符并使用{{1}提取accessKeyId }}:
