[RESOLVED][1.0.0.rc1] cannot parse webhook

My gogs webhook return 400 status code suddenly, drone debugs tell me

  "level": "debug",
  "msg": "cannot parse webhook: Invalid webhook signature",
  "time": "2018-11-25T14:01:05Z"

My Gogs version is 0.11.66. I have try to remove gogs webook setting and disable repository and active repository again and again, but it doesn’t work. does anyone knows what should i do to fix it?

I have fix it. That’s because there has some special character that making signature sha256 calculate failure.
