Question

我有下一段代码：

echo -n "{ \"data\":" > test.json
echo -n "  [" >> test.json

sqcur=0
sqtotal=`ls /etc/squid?.conf | wc -l`
tcp_ports=$(grep "port" /etc/squid?.conf |awk '{print $2}' |sed 's|.*[0-9]*\:||g'|sort|uniq|xargs)

for squidconf in `ls /etc/squid?.conf`; do
  let "sqcur+=1" > /dev/null
  squidident=`echo $squidconf | sed 's/.*\///' | awk -F '.' '{print $1}'`
  tcp_ports=$(grep "port" $squidconf |awk '{print $2}' |sed 's|.*[0-9]*\:||g'|sort|uniq|xargs)  
  if [ $sqcur -lt $sqtotal ]; then
    echo -n "    { \"{#SQPROC}\": \"/usr/local/squid/bin/squid\", \"{#SQPROC_IDENT}\": \"${squidident}\", \"{#SQPROC_ARGS}\": \"-D -C -F -f ${squidconf}\", \"{#SQPROC_PORT}\": \"${tcp_ports}\", \"{#SQPROC_CONF}\": \"${squidconf}\" }," >> test.json
  else
    echo -n "    { \"{#SQPROC}\": \"/usr/local/squid/bin/squid\", \"{#SQPROC_IDENT}\": \"${squidident}\", \"{#SQPROC_ARGS}\": \"-D -C -F -f ${squidconf}\", \"{#SQPROC_PORT}\": \"${tcp_ports}\", \"{#SQPROC_CONF}\": \"${squidconf}\" }" >> test.json  
  fi
done

echo -n "  ]" >> test.json
echo "}" >> test.json

它提供了json文件中的下一个内容：

{
        "data": [
            {
                "{#SQPROC}": "/usr/local/squid/bin/squid",
                "{#SQPROC_IDENT}": "squid1",
                "{#SQPROC_ARGS}": "-D -C -F -f /etc/squid1.conf",
                "{#SQPROC_PORT}": "1111 2222",
                "{#SQPROC_CONF}": "/etc/squid1.conf"
            },

但是我希望在多个port值的情况下获得下一个结果：

{
        "data": [
            {
                "{#SQPROC}": "/usr/local/squid/bin/squid",
                "{#SQPROC_IDENT}": "squid1",
                "{#SQPROC_ARGS}": "-D -C -F -f /etc/squid1.conf",
                "{#SQPROC_PORT_1111}": "1111",
                "{#SQPROC_PORT_2222}": "2222",
                "{#SQPROC_CONF}": "/etc/squid1.conf"
            },

你能帮忙吗？

你可能正在寻找这样的东西：

for port in $tcpports
do
     all_ports="${all_ports} \"{#SQPROC_PORT_$port}\": \"$port\","
done

在此循环结束时，您将拥有一个all_ports变量，其中包含以下内容：

"{#SQPROC_PORT_1111}": "1111", "{#SQPROC_PORT_2222}": "2222",

例如。

要在您已有的代码中轻松集成，我会在您的for循环中提出一些小的更改。对于每次迭代，构建一个变量json_content，该变量将包含该迭代和迭代结束时json的数据，只需打印$json_content：

echo -n "{ \"data\":" > test.json
echo -n "  [" >> test.json

sqcur=0
sqtotal=`ls /etc/squid?.conf | wc -l`

for squidconf in `ls /etc/squid?.conf`; do
    let "sqcur+=1" > /dev/null
    squidident=`echo $squidconf | sed 's/.*\///' | awk -F '.' '{print $1}'`
    tcp_ports=$(grep "port" $squidconf |awk '{print $2}' |sed 's|.*[0-9]*\:||g'|sort|uniq|xargs)  
    json_content="{ \"{#SQPROC}\": \"/usr/local/squid/bin/squid\", \"{#SQPROC_IDENT}\": \"${squidident}\", \"{#SQPROC_ARGS}\": \"-D -C -F -f ${squidconf}\","
    for port in $tcp_ports
    do
         json_content="$json_content \"{#SQPROC_PORT_$port}\": \"$port\","
    done
    json_content="$json_content \"{#SQPROC_CONF}\": \"${squidconf}\" }"
    if [ $sqcur -lt $sqtotal ]; then
        json_content="${json_content},"
    fi
    echo -n "    ${json_content}" >> test.json
done

echo -n "  ]" >> test.json
echo "}" >> test.json

我无法验证循环的其余部分。我没有鱿鱼！但是当您重新计算for循环中的tcp_ports时，我在for循环之前删除了初始化

希望这有帮助，
祝你好运！

在循环中添加每个元素命名的值
