HTTPClient Class Reference

A simple HTTP Client The HTTPClient is composed of:

  • The actual client (HTTPClient)
  • Classes that act as a data repository, each of which deriving from the HTTPData class (HTTPText for short text content, HTTPFile for file I/O, HTTPMap for key/value pairs, and HTTPStream for streaming purposes)

HTTPResult addRootCACertificate ( const char *  cert )

Stores a root CA certificate for host authentication of a website.

Each new line should end with "\r\n" including the last line of each certificate. Pass a pointer to the char array containing the certificate stored as a c-string. Pass a NULL pointer to reset all certificates stored. (Can pass in multiple certificates with one function call if the array contains concatenated certificates)

const char *  password 
)

Provides a basic authentification feature (Base64 encoded username and password) Pass two NULL pointers to switch back to no authentication.

Parameters:
userusername to use for authentication, must remain valid durlng the whole HTTP session
userpassword to use for authentication, must remain valid durlng the whole HTTP session
