用python方便的格式化json

用python来格式化json输出

最近在研究F5的 rest api， 通过curl 来get输出的都是json。问题也跟着来了，默认输出是不带格式的，人类很难读。
同样redis也是这样，用redis-cli输出的一坨子json很难识别。

比如这样：

$ curl -k -u admin:admin -X GET https://1xxx/mgmt/tm/ltm/pool/poolaaa/members/stats/

{"kind":"tm:ltm:pool:members:memberscollectionstats","selfLink":"https://localhost/mgmt/tm/ltm/pool/poolaaa/members/stats?ver=1x.x.x","entries":{"https://localhost/mgmt/tm/ltm/pool/poolaaa/members/~Common~1xxxx2
.....
省略输出了

万能的python登场

只需要用我们万能的python，就可以帮助我们格式化成人类习惯的格式了：

python -m json.tool

$curl -k -u admin:admin -X GET https://xxx/mgmt/tm/ltm/pool/poolaaa/members/stats/ | python -m json.tool

 % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  2626  100  2626    0     0   3999      0 --:--:-- --:--:-- --:--:--  3996
{
    "entries": {
        "https://localhost/mgmt/tm/ltm/pool/pool_aaa/members/~Common~xxxx:xxx0/stats": {
            "nestedStats": {
                "entries": {
                    "addr": {
                        "description": "1xxx"
                    },
                    "connq.ageEdm": {
                        "value": 0
                    },
                    。。。。
                    ....

同样的道理.redis-cli也可以

比如，我要看ansible收集的fact

./redis-cli --raw -p xxxx get "ansible_factxxxx" | python -m json.tool

{
    "ansible_all_ipv4_addresses": [
        "xxxx"
    ],
    "ansible_all_ipv6_addresses": [
        "xxxx"
    ],
    "ansible_architecture": "x86_64",
    "ansible_bios_date": "07/09/2012",
    "ansible_bios_version": "6.00",
    "ansible_cmdline": {
        "BOOT_IMAGE": "/vmlinuz-3.10.0-229.el7.x86_64",
        "LANG": "en_US.UTF-8",
        "crashkernel": "auto",
        "quiet": true,
        "rd.lvm.lv": "rhel/root",
        "rhgb": true,
        "ro": true,
        "root": "/dev/mapper/rhel-root"
    },

.......

python在手，工作无忧啊。
