Handlers¶

There are three handlers included in the HTTPServer package:

• SimpleHandler
• FSHandler
• RPCHandler

You can also create a custom handler by simply inheriting the HTTPRequestHandler class.

HTTPRequestHandler base class¶

To add a handler class to a server, simply use the server's addHandler method:

template<typename T>
void addHandler(const char* path)

Append an handler of type T to the handlers list, for requests of path starting with path.

Example:

svr.addHandler<SimpleHandler>("/hello");

SimpleHandler¶

This is a basic handler which returns an hello world message.

Reference¶

No specific method for this handler.

FSHandler¶

This handler allows you to server files from a filesystem, such as the mbed's drive or a SD Card. Note that to use it you have to instantiate the file system yourself.

Reference¶

static void mount(const string& fsPath, const string& rootPath)

Make the files located under fsPath available under the server's rootPath directory.

RPCHandler¶

This handler allows you to execute RPC requests using GET commands.

Reference¶

No specific method for this handler.

Examples¶

The second example of the HTTP Server wiki page uses all-three handlers.
