Sorry my English is poor.

I use nodemcu to get a json data.

By this String alldata = client.readString();

But it turn this:

  HTTP/1.1 200 OK
  Server: nginx
  Date: Sat, 10 Aug 2019 04:53:16 GMT
  Content-Type: application/json; charset=utf-8
  Content-Length: 152
  Connection: keep-alive
  X-RateLimit-Limit-day: 20000
  X-RateLimit-Remaining-day: 19968
  Cache-Control: no-cache
  Pragma: no-cache

  X-Kong-Proxy-Latency: 2
