Method for executing an HTTP GET request. If data type is not specified, it will default to
'text'. This is equivalent to calling httpDo(path, 'GET'). The 'binary' datatype will return a Blob object, and the 'arrayBuffer' datatype will return an ArrayBuffer which can be used to initialize typed arrays (such as Uint8Array).Examples
