1 Getting started Access to the Flexdisk API is available from any platform capable of issuing HTTPS URL based web queries, including all mobile device platforms. Accessing the Flexdisk is very simple, it was designed to be straight forward and universally accessible from most web friendly programming environments. API Overview The F-Response Flexdisk API consists of two main parts, flexd and hscsi. Flexdisk API Overview /flexd? Explore, Read, Extract Provides access to file system structures and meta data. /hscsi? Read Provides read access to physical device (memory) raw data. Authentication Access to the Flexdisk is protected using standard HTTP Basic Authentication over SSL. All web queries are authenticated using this model. Data Encoding Unless otherwise indicated the Flexdisk API makes use of the Javascript Object Notation (JSON) data encoding format. JSON is well documented in the industry and there are numerous libraries capable of manipulating JSON encoded content. More details on JSON and consuming JSON in your applications is available at Developing applications that use the F-Response Flexdisk We are very excited that you ve chosen to develop applications that use the patented F-Response Flexdisk technology. To that end we would love to hear about your application, if it s available for purchase or open source we d be happy to link to it from our site and give you access to the F-Response Flexdisk Enabled logo for use on your website and materials. <LOGO FORTHCOMING> 1
2 Flexdisk Web Request and Response Values Flexdisk Web Query Request Arguments 1 Request Meaning Values Notes Argument tgt Target vol-c,rdisk0,etc Indicates the target name as provided by the main Flexdisk handler. enc Encoding json,csv,html Instructs the Flexdisk handler to return the output in one of three potential encoding formats, JSON, CSV, or HTML. Default is HTML unless otherwise configured node File or <numeric> Indicates the desired node by numeric value. Directory Node value type Response value type data,meta,read Indicates the desired value type, data for accessing the entire file, meta for file metadata, or read for name offset len File or Directory Name File Offset to start at Length of file content to obtain <numeric> <numeric> reading from a select location within a file. Indicates the name of the file or directory requested. Valid only for Read Operations (type=read), value in bytes. Valid only for Read Operations (type=read), value in bytes. Flexdisk Web Query Response Values (JSON Encoded Responses Only) Response Meaning Values Notes name Name of the type uri Type of URL used to access the specific <URL> Indicates the name of the, depending on usage it may be a file, directory, or a disk/device. Indicates the type of the. Examples include ntfs for file system type, or dir for directory node type. Provides a URL to access the (data or explore) depending on the. node Node value <numeric> Numeric identifier for a given. sectorsize Size of a <numeric> Indicates the Sector Size of a target device. single sector volsize Size of the <numeric> Indicates the size of the target device. device atime Access <unix time> Indicates the last access time in unix time. atime_hires Access <win32 time> Indicates the last access time in win32 time, where available. 1 Unless otherwise noted all URL queries use the /flexd? preface. 2
