字符串如下：
mac_address=08%3A00%3AX7%3E5A%3AGB%3AE0&language=zh&device_brand=Android&type=readmore&uuid=11230&device_id=1900232321&smix=a&before_timestamp=01&show_moment=20&os_version=6.0.1&channel=xiaomi

t1.sh 文件内容如下：

input_str=$1

echo $input_str | sed 's/&/\n/g' | awk -F "=" '{print "'\''" $1 "'\''" ":" "'\''" $2 "'\''"  "," }'

执行 ： sh t1.sh 'mac_address=08%3A00%3AX7%3E5A%3AGB%3AE0&language=zh&device_brand=Android&type=readmore&uuid=11230&device_id=1900232321&smix=a&before_timestamp=01&show_moment=20&os_version=6.0.1&channel=xiaomi'
