+JSON RPC (both the JSONRPC4Lua implementation and the <a href="http://www.jsolait.net/">jsolait Javascript</a> implementation) send the http request with a Content-Type of <code>text/plain</code>.<p/>
+
+CGILua 5.0 does not accept <code>text/plain</code> content, and will generate an error of 'Unsupported Media Type: text/plain'.<p/>
+
+This is easily patched in CGILua 5.0 by making the following change to <code>cgilua/post.lua</code>, line 286:<p/>
+Change:<pre>
+ elseif strfind (contenttype, "text/xml") then
+</pre>
+to
+<pre>
+ elseif strfind (contenttype, "text/xml") or strfind (contenttype, "text/plain") then
+</pre>
+This makes CGILua handle <code>text/plain</code> as it does <code>text/xml</code>, without parsing the incoming POST data.<p/>
+
+<b>Please note:</b> I have requested the maintainers of CGILua to make this change to CGILua, whereafter this patch will no longer be required.

+ <h1><a name="news"></a>Latest News</h1>
+ <p><small>(2009-08-06)</small> We've changed the JSON4Lua and JSONRPC4Lua licence from the GPL to the MIT licence, like Lua itself.</p>
+ <p>
+ The 0.9.20 release fixes a bug in Lua 5.1 operation, introduces a <a href="#json_null"><code>json.null</code></a> value to force null values in JSON encodings, improves performance (over 50% faster on some tests), and permits <code>/* comments */</code> in the JSON string being decoded.
+ </p>
+
+ <!-- ***************** INTRODUCTION ***************** -->
+ <h1><a name="introduction"></a>Introduction</h1>
+ JSON4Lua and JSONRPC4Lua implement <a href="http://www.json.org">JSON (JavaScript Object Notation)</a> encoding and decoding and a <a href="http://www.json-rpc.org/">JSON-RPC-over-http</a> client for <a href="http://www.lua.org/">Lua</a>.<p/>
+
+JSON is JavaScript Object Notation, a simple encoding of Javascript-like objects that is ideal for lightweight transmission of relatively weakly-typed data.
+A sub-package of JSON4Lua is JSONRPC4Lua, which provides a simple JSON-RPC-over-http client and server (in a CGILua environment) for Lua. Please seen the documentation below for JSONRPC4Lua.
+
+ <!-- ***************** LICENCE ***************** -->
+ <h1><a name="licence"></a>Licence</h1>
+ JSON4Lua is licensed under the MIT Consortium licence like Lua itself. Please see <a href="LICENCE.txt">LICENCE.txt</a> for details.<p/>
+
+ <!-- ***************** REQUIREMENTS ***************** -->
+ <a name="requirements"></a><h1>Requirements</h1>
+ JSON4Lua is a pure-Lua module that is Lua 5.0 compatible (if you have <a href="http://www.keplerproject.org/compat/">compat-5.1</a> for Lua 5.0). JSON4Lua also works (perfectly, I hope) under Lua 5.1, which is where I largely use it nowadays. Since Lua is platform independent, so is JSON4Lua.<p/>
+
+ The JSON4RPC sub-module requires <a href="http://www.cs.princeton.edu/~diego/professional/luasocket/">Lua Socket 2.0</a>. It uses <code>socket.http</code> for for the RPC over http connection. Socket 2.0 includes <code>ltn12</code>, which is also used by JSON4RPC.<p />
+
+ To use <code>json.rpcserver</code> you need a <a href="http://www.keplerproject.org/cgilua/">CGILua</a> enabled webserver. However, a quick <a href="cgilua_patch.html">patch</a> is required in CGILua 5.0 to support JSON-RPC.

+ <!-- ***************** START OF INSTALLATION SECTION ***************** -->
+ <h1><a name="installation"></a>Installation</h1>
+ As of version 0.9.10, all the JSON4Lua files are contained in the <code>json</code> subdirectory in the distribution zip.<p />
+ Simply copy the <code>json</code> subdirectory so that it is in your Lua path.<p />
+ Ensure that your <code>LUA_PATH</code> variable permits module resolution of the form <code>?/?.lua</code>.<p />
+ <b>Example</b>
+ <div class="example">
+ </div>
+ <h2>Using Windows</h2>
+ Under Windows, set your Lua path as (my Lua installation is in <code>c:\proj\lua\</code>): <p/>
+ <code>
+ set LUA_PATH=c:\proj\lua\?.lua;c:\proj\lua\?\?.lua;?.lua
+ </code><p/>
+ For compat-5.1.lua to start when Lua starts (if you're using Lua 5.0), you also need:<p/>
+ <code>
+ set LUA_INIT=@c:\proj\lua\compat-5.1.lua

+ <h1><a name="usage"></a>Usage &amp; Reference</h1>
+ The following functions in <b>JSON4Lua</b> and <b>JSONRPC4Lua</b> are of interest:<p />
+ <dl>
+ <dt><a name="json_encode"></a><code>string <b>json.encode</b>( lua_object )</code></dt>
+ <dd>Returns the Lua object JSON encoded into a string.<p/>
+ <b>Example</b>
+ <div class="example">
+ <code>
+ json = require("json")<br/>
+ print (json.encode( { 1, 2, 'fred', {first='mars',second='venus',third='earth'} } ))
+ </code><p/>
+ prints<p/><code> [1,2,"fred", {"first":"mars","second":"venus","third","earth"}]</code>
+ </div>
+
+ </dd>
+ <dt><a name="json_decode"></a><code>lua_object <b>json.decode</b>( json_string )</code></dt>
+ <dd>Decodes the JSON encoded data structure, and returns a Lua object with the appropriate data.<p/>
+ <b>Example</b>
+
+ <div class="example">
+ <code>
+ json = require("json")<br/>
+
+ testString = [[ { "one":1 , "two":2, "primes":[2,3,5,7] } ]]<br/>
+ o = json.decode(testString)<br/>
+ table.foreach(o,print)<br />
+ print ("Primes are:")<br />
+ table.foreach(o.primes,print)
+ </code><p/>
+ prints:<p/>
+ <pre>
+one 1
+two 2
+primes table: 0032B928
+Primes are:
+1 2
+2 3
+3 5
+4 7</pre>
+ </div></dd>
+
+ <dt><a name="json_null"></a><code><b>json.null</b></code></dt>
+ <dd>Returns a unique value that will be encoded as a <code>null</code> in a JSON encoding.
+ <p>This is necessary in one situation. In Lua, if a key in a table has a <code>nil</code> value, the key is simply discarded (since any non-existent key has a nil value). The encoding of arrays has been built to manage this nil-values in arrays, but associative arrays provide a problem. Consider:
+ <div class="example"><pre>t = { user="test", password=nil }</pre></div>
+ Since Lua simply discards the <code>password</code> key, JSON4Lua encodes this as the JSON string
+ <div class="example"><pre>{"user":"test"}</pre></div>
+ If, for some reason, your JSON RPC Server requires a defined <code>null</code> value, use the following code:
+ <div class="example"><pre>t = { user="test", password=json.null }</pre></div>
+ This will now correctly encode to:
+ <div class="example"><pre>{"user":"test","password":null}</pre></div>
+ Incidentally, <code>json.null</code> is simply a function that returns itself, so that you can use either <code>json.null</code> or <code>json.null()</code> as you fancy.
+ </dd>
+
+
+ <dt><a name="json_rpc_call"></a><code>result, error <b>json.rpc.call</b> ( url, method, ...)</code></dt>
+ <dd>Calls the named method on the given url with the arg parameters. Returns the result and the error. If <code>error</code> is <code>nil</code>, no error occurred.<p/>
+ <b>Example</b>
+ <div class="example">
+ <pre>require ("json.rpc")
+result, error = json.rpc.call("http://jsolait.net/testj.py","echo","Test echo!")
+print(result)</pre>
+ <p />prints<p />
+ <pre>Test echo!</pre>
+ </div>
+ </dd>
+ <dt><a name="json_rpc_proxy"></a><code>proxyServer = <b>json.rpc.proxy</b> (url)</code></dt>
+ <dd>Creates a proxy server object on which JSON-RPC calls can be made. Each call will return the <code>result, error</code>. If <code>error</code> is <code>nil</code>, no error occurred.<p/>
+ <b>Example</b>
+ <div class="example">
+ <pre>
+require ("json.rpc")
+server = json.rpc.proxy("http://jsolait.net/testj.py")
+result, error = server.echo('Test echo!')
+print(result)</pre>
+ <p />prints<p />
+ <pre>Test echo!</pre>
+ </div>
+ </dd>
+
+ <dt><a name="json_rpcserver_serve"></a><code><b>json.rpcserver.serve</b>(object[, packReturn])</code></dt>
+ <dd>
+ Handles an incoming CGILua request as a JSON RPC request and serves the request from
+ the given object.
+ <p />The optional <code>packReturn</code> parameter, if set <code>true</code>, will, if the requested
+ method returns more than one value, pack these returned values into an array. If only a single value
+ is returned, it is not packed into an array. If <code>packReturn</code> is <code>false</code> (or not set), only the first
+ return value from the requested method will be returned. This is necessitated since the JSON protocol does not permit a method call to return more than a single value.
+ <p/>
+
+ <code>serve</code> returns nothing.<p/>
+
+ <b>Example</b>
+ <div class="example">
+ <pre>

+ <!-- ***************** HISTORY AND ROADMAP ***************** -->
+ <h1><a name="roadmap"></a>History &amp; Roadmap</h1>
+ The downloads sections details the versions and their related histories. I will wait for Lua 5.1 to be final (expected late January) before making the JSON4Lua module beta. If no serious bugs or objections are encountered, I will make the module 1.0 on 1 April 2006 (to coincide with April Fool's day!)

+-- JSON4Lua: JSON encoding / decoding support for the Lua language.
+-- json Module.
+-- Author: Craig Mason-Jones
+-- Homepage: http://github.com/craigmj/json4lua/
+-- Version: 1.0.0
+-- This module is released under the MIT License (MIT).
+-- Please see LICENCE.txt for details.
+--
+-- USAGE:
+-- This module exposes two functions:
+-- json.encode(o)
+-- Returns the table / string / boolean / number / nil / json.null value as a JSON-encoded string.
+-- json.decode(json_string)
+-- Returns a Lua object populated with the data encoded in the JSON string json_string.
+--
+-- REQUIREMENTS:
+-- compat-5.1 if using Lua 5.0
+--
+-- CHANGELOG
+-- 0.9.20 Introduction of local Lua functions for private functions (removed _ function prefix).
+-- Fixed Lua 5.1 compatibility issues.
+-- Introduced json.null to have null values in associative arrays.
+-- json.encode() performance improvement (more than 50%) through table.concat rather than ..
+-- Introduced decode ability to ignore /**/ comments in the JSON string.
+-- 0.9.10 Fix to array encoding / decoding to correctly manage nil/null values in arrays.

+-- Homepage: http://github.com/craigmj/json4lua/
+-- Version: 1.0.0
+-- This module is released under the MIT License (MIT).
+-- Please see LICENCE.txt for details.
+--
+-- USAGE:
+-- This module exposes two functions:
+-- proxy( 'url')
+-- Returns a proxy object for calling the JSON RPC Service at the given url.
+-- call ( 'url', 'method', ...)
+-- Calls the JSON RPC server at the given url, invokes the appropriate method, and
+-- passes the remaining parameters. Returns the result and the error. If the result is nil, an error
+-- should be there (or the system returned a null). If an error is there, the result should be nil.
+--
+-- REQUIREMENTS:
+-- Lua socket 2.0 (http://www.cs.princeton.edu/~diego/professional/luasocket/)
+-- json (The JSON4Lua package with which it is bundled)
