1.比如post表单,传body 形式非json格式  而是  username=admin&password=password

ngx.req.read_body()
local args = ngx.req.get_body_data()

  

local asArr = split(args,"&")
if asArr then
  for key,val in pairs(asArr) do
    local subArr = split(val,"=")
    print(subArr[1])
  end
end

  

function split(s, p)
    local rt= {}
    string.gsub(s, '[^'..p..']+', function(w) table.insert(rt, w) end )
    return rt

end
