No, the request body is not read yet at the phase where set_by_lua
(and those ngx_rewrite directives) runs. Try using the rewrite_by_lua
directive instead where you can call ngx.req.read_body() in Lua to
explicitly read the request body (otherwise the body is still not
read):

http://wiki.nginx.org/HttpLuaModule#ngx.req.read_body

But note that by default, rewrite_by_lua always runs after those
ngx_rewrite directives like "set" or "if". If you want the other way
around, just turn on the rewrite_by_lua_no_postpone directive:
