I am trying to update values to Firebase. According to Firebase:

curl -X PUT -d '{ "first": "Jack", "last": "Sparrow" }' \
  'https://[PROJECT_ID].firebaseio.com/users/jack/name.json'

We can update using put command. Using curl works fine, but when I look at the header of ESP8266HTTPClient, I don't see any put or patch method there.

I can only see the following:

int GET();
int POST(uint8_t * payload, size_t size);
int POST(String payload);

Whereas in NodeMCU documentation, it is clearly stated it supports the put method too.

http.put(url, headers, body, callback)

http.put() documentation

I cannot find any example.

How can I implement the put method in NodeMCU?

    Just because NodeMCU's Lua HTTP library has a PUT method, doesn't mean Arduino's C++ HTTP library has it too.

  • Also you are only using the NodeMCU board not the firmware, so "implementing the put method in nodemcu" makes no sense.

pardon me if i asked too soon. I found the answer. all verb are supported. but post and get got their own names.

 int httpCode = http.sendRequest("PUT", String(data));

enven post method implement the sendRequest.
