shell实现数据json格式转换

redis中按hash格式存放的数据,转换到json格式

例子1:

redis内数据格式
test1
"dbname=test1|username=db2inst3|passwd=db2inst3|ip=192.168.1.61|port=60004|"
bmw
"dbname=bmw|username=db2inst3|passwd=db2inst3|ip=192.168.1.113|port=50000|"
test2
"dbname=test2|username=db2inst3|passwd=db2inst3|ip=192.168.1.113|port=50000|"

shell:
awk 'BEGIN{printf "["}'
echo "hgetall SrcLogInfo " | ../redis | while read line
do    
    strA="|"
    #num=echo ${line | wc -c}
    awk 'BEGIN{printf "{"}'
    ret=\"$line\"  
    echo ${ret}
    result=$(echo $line | grep "${strA}") 
    if [ -n "$result" ]; then
        awk 'BEGIN{printf "},"}'
    else
        awk 'BEGIN{printf ":"}'
    fi

done
awk 'BEGIN{printf "]"}'

转换结果为:json格式
[{
        "test1": "dbname=test1|username=db2inst3|passwd=db2inst3|ip=192.168.1.61|port=60004|"
    },
    {
        "bmw": "dbname=bmw|username=db2inst3|passwd=db2inst3|ip=192.168.1.113|port=50000|"
    },
    {
        "test2": "dbname=test2|username=db2inst3|passwd=db2inst3|ip=192.168.1.113|port=50000|"
    }
]

 

例子2:

redis存的数据格式:
1) "db2inst1"
2) "{\"serverip\":\"192.168.1.113\",\"dbip\":\"192.168.1.225\",\"dbport\":\"50000\",\"nodename\":\"node225\",\"dbname\":\"db2_10\",\"dbaliname\":\"db2inst1\",\"instname\":\"db2inst1\"}"
3) "fea"
4) "{\"serverip\":\"192.168.1.113\",\"dbip\":\"192.168.1.225\",\"dbport\":\"50000\",\"nodename\":\"node225\",\"dbname\":\"db2_10\",\"dbaliname\":\"fea\",\"instname\":\"db2inst1\"}"
5) "bmw"
6) "{\"serverip\":\"192.168.1.113\",\"dbip\":\"192.168.1.61\",\"dbport\":\"60004\",\"nodename\":\"node61\",\"dbname\":\"test1\",\"dbaliname\":\"bmw\",\"instname\":\"db2inst3\"}"

shell:
awk 'BEGIN{printf "["}'
echo "hgetall catainfo " | ../redis| while read line
do
    i=$(($i+1))
    if [[ $(($i%2)) -eq 0 ]];then
         printf $line,
    fi
done
awk 'BEGIN{printf "]"}'

//最后格式就不展示了
