无法解析主机 - 传递变量时 cURL 请求无效

我正在尝试使用 shell 脚本，并且我相信我完全按照应有的方式编写了命令，但是，我遇到了奇怪的错误。也许我没有正确地逃避，但我已经尝试过各种事情。

myscript.sh

function seconds_to_readable () {
    num=$1
    min=0
    hour=0
    if((num>59));then
            ((sec=num%60))
            ((num=num/60))
            if((num>59));then
                    ((min=num%60))
                    ((num=num/60))
                    if((num>23));then
                            ((hour=num%24))
                    else
                            ((hour=num))
                    fi
            else
                    ((min=num))
            fi
    else
            ((sec=num))
    fi
    echo "$hour""h "$min"m "$sec"s"
}

输出是：

引用肯定会变得一团糟。首先使用heredoc 将整个 json 对象放入变量中，然后将其传递给curl。

你可以这样做：

read -r -d '' _json <<EOJSON
{ 
    "blocks": [ 
        { 
            "type": "section", 
            "text": { 
                "type": "mrkdwn", 
                "text": ":tada: $ENVIRONMENT website has been deployed in *$(seconds_to_readable $runtime)*" 
                } 
        }, 
        { 
            "type": "context", 
            "elements": [ 
                { 
                    "type": "mrkdwn", 
                    "text": "*Environment:* $ENVIRONMENT" 
                }, 
                { 
                    "type": "mrkdwn", 
                    "text": "*Started at:* $DEPLOY_STARTED_AT" 
                }, 
                { 
                    "type": "mrkdwn", 
                    "text": "*Runtime:* $(seconds_to_readable $runtime)" 
                } 
            ] 
        }, 
        { 
            "type": "context", 
            "elements": [ 
                { 
                    "type": "mrkdwn", 
                    "text": "*Yarn install:* $(seconds_to_readable $runtimeYarnInstall)" 
                }, 
                {

                    "text": "*Generate (modern):* $(seconds_to_readable $runtimeGenerate)" 
                }, 
                { 
                    "type": "mrkdwn", 
                    "text": "*Wrangler publish:* $(seconds_to_readable $runtimeWrangler)" 
                } 
            ] 
        }, 
        {
