Runs the javascript backend (using duktape), parses HTTP requests (using qdecoder), provides lower level interface to CCSP

Introduction

JSE is a JavaScript interpreter for running command line scripts and CGI scripts.

Features

• Built in JavaScript Request object has properties for each of the CGI environment variables
• The Request object has a QueryParameters property, an object that comprises each of the HTTP request parameters
• The QueryParameters object has properties that comprise each of the HTTP cookies in the request
• The QueryParameters object has properties that comprise each of the uploaded files
• Generation of XML documents from JavaScript objects may be enabled
• Encryption and decryption of JavaScript strings and buffers may be enabled
• Fast CGI support may be enabled

Dependencies

JSE requires the following libraries:

• duktape
• qdecoder
• libxml2 - optional
• libcrypto - optional
• fastcgi - optional

Configuring

The build needs to be configured using CMake with a version of at least 3.8. Create a build directory in the same directory as you have unpacked the JSE source.

Build options

Build options can be enabled using the CMake -D switch for example:

$ cmake ../jse -DENABLE_LIBXML2=ON -DENABLE_LIBCRYPTO=ON

The following build options are available:

Option	Default value	Alternative	Description
BUILD_RDK	OFF	ON	Build with Cosa CCSP API
FAST_CGI	OFF	ON	Enable Fast CGI support
ENABLE_LIBXML2	OFF	ON	Enable XML generation API
ENABLE_LIBCRYPTO	OFF	ON	Enable encryption/decryption API

Building

Once configured JSE can be built using make.

$ make

Command syntax

The command syntax is:

jse [options] [script_name]

• In non HTTP mode the script name is optional. If it is omitted the script is read from standard input
• In HTTP CGI mode the script name is required
• In HTTP Fast CGI mode the script name is ignored. The script name is provided via the SCRIPT_FILENAME environment variable as part of the Request object.

The following command line options are available:

Option	Long Option	Description
-c	--cookies	Process HTTP cookies
-e	--enter-exit	Enable function enter/exit debug
-g	--get	Process HTTP GET requests
-h	--help	Help
-n	--no-ccsp	Do not initialise CCSP (when built in)
-p	--post	Process HTTP POST requests
-u	--upload-dir	Specify a different HTTP file upload directory (default /var/jse/uploads)
-v	--verbose	Verbosity. Use multiple times to turn up verbosity
