How to capture certain string in "API request's body" using LUA in NginX.

[Balasekhar Nelli]

Hi,

I just statred using LUA for NginX. I have tough time using ngx_lua functions.

What method should I use to capture the certain string from the "API request's body"

---------------------------------------------------------------------------------------------------------------------------

http://10.17.3.250:80/sdk/v3

Headers:

DFM-Application-Id: ZaXIZrKT

Dfm-Device-id: android1

DFM-Timestamp: 1489582211

DFM-SHA256-Verifier: 313ecbcb52ef7e09f9fb548325f3530619eb90821db5c880ec3c3b3ca18847c6

Content-Type: application/json

dfm_test: true

Body:

-------

[ {

    "app_id": "sm_id,

    "urlType": "UL",

    "event_type": "deeplink_event",

    "timezone_offset": 19800,

    "timestamp": 1488783314,

    "sdk_version": "4.0.1",

    "url": "https:/url",

    "event_seq": 18,

    "custom_fields": {},

    "platform": "ios",

    "is_first": false,

    "ts": 14887njn83314945,

    "session_id": 148ubbd8783307944

  }]

--------------------------------------------------------------------------------------------------------------------

In the body I want to capture "sdk_version": "4.0.1" . If there is match I have to divert the traffic to certain cluster else to other cluster.

I have tried using " body_filter_by_lua', but failed.

Thanks,

Bala

To get request body data, you can use ngx.req.get_body_data method in content_by_lua_block
