gsub request_uri paramater

[Stan Wong]

Hi,

Is it possible to gsub request uri parameter before send to upstream?

original client request query string = /rpc/validation.php?token=aaaa&tokensalt=bbbbb&version=abc

new url /rpc/validation.php?token=aaaa&tokensalt=bbbbb&version=abc123

I tried below code but the URL query string parameter remain the same when forward to upstream.

local args = ngx.req.get_uri_args()

args.version = "abc123"

ngx.req.set_uri_args(args)

hello,

you can process it with ngx.var.args and ngx.re.split()
