Getting the body of a POST request is a very common use-case in ESP8266WebServer. But it's now undocumented and very hard to find out how without reading whole
PostServer
example or source code. So I document it in README.Also, I think there should be a
requestBody()
method. It's more reasonable thanarg("plain")
.
