unable to found cjson & resty.jwt

[saurabhmehta86]

Working with nginx r21.

I need to decode jwt token and extract the value of a key out of it. I have downloaded the following libs

1. https://github.com/cdbattags/lua-resty-jwt#verify
2. https://github.com/openresty/lua-resty-string
3. https://github.com/jkeys089/lua-resty-hmac
4. https://github.com/openresty/lua-cjson

All above mentioned libs are present in /etc/nginx/saurabh/

Nginx.conf

load_module /etc/nginx/ndk_http_module.so; load_module /etc/nginx/ngx_http_lua_module.so; .... http { lua_package_path "/etc/nginx/saurabh/*/lib/?.lua;;"; .... server{ .... rewrite_by_lua_file test.lua; .... } }

test.lua

function validate()
print("<-----Starting validate Client IP----->"); print("<-----r.uri-------------------------->", ngx.var.uri);

if (string.find(ngx.var.uri, '/user/logout'))  then
    print("validate--> Returning Success.");
    return 1;
end

if (ngx.var.uri == '/sso/loggedout') then 
    print("validate-->/sso/loggedout. Returning Success.");
    return 1;
end

local authn_token = ngx.var.cookie_AUTHN_TOKEN;
if (authn_token == undefined)  then
    print("validate-->authn_token cookie is found undefined. Returning Success.");
    return 1;
end

local cjson = require "cjson";
local jwt = require "resty.jwt";
local jwt_obj = jwt:verify("lua-resty-jwt", authn_token);
print("Decoded token is------------------------------>", cjson.encode(jwt_obj));
ngx.say(cjson.encode(jwt_obj));

end

validate()

I don't believe I was able to recreate when this was originally posted. Let me test this weekend and will respond with my findings.
