// ==========================API DOCS=======================================
// API Name: Stream data to specified file
// Action: Write the data from http to the file streamingly
// API URL: /io/{contianer}/{followingpath}
// REQUEST: PUT
// Parameters:
// - contianer(in URL): the container name
// Returns:
// - HTTP 200: No error, the file is written by force
// When success, the returned header Parent-Node(if accessed) will
// contain its parent inode and File-Node will indicate the file itself.
// - HTTP 404: Either the container or the filepath does not exist.
// - HTTP 500: Error. The body is supposed to return error info.
