I’m using tcp-log,but I cannot find the POST request body. If I want to get the request body, what should I do?

Logging Request Body/ Response Body with HTTP LOG been discussed before, take a look at the PR I linked there long ago, there are many reasons to not log request and response bodies, performance around mem utilization and security reasons are valid concerns

Literally line 61 and 62 copy paste my dude -

github.com

Optum/kong-upstream-jwt/blob/master/src/access.lua#L61


    b64_encode(json.encode(data))
  }
  local signing_input = table_concat(segments, ".")
  local signature = openssl_pkey.new(key):sign(openssl_digest.new("sha256"):update(signing_input))
  segments[#segments+1] = b64_encode(signature)
  return table_concat(segments, ".")
end


local function add_jwt_header(conf)
  local kong_pkey = getKongKey("pkey", private_key_location)
  ngx.req.read_body()
  local req_body  = ngx.req.get_body_data()
  local digest_created = ""
  if req_body ~= nil then
    local sha256 = resty_sha256:new()
    sha256:update(req_body)
    digest_created = sha256:final()
  end


  local payload = {
        payloadhash = str.to_hex(digest_created),
