| <h2>Actionscript 3.0 Tutorial</h2> |
| |
| <h3>Introduction</h3> |
| |
| <p> |
| All Apache Thrift tutorials require that you have: |
| |
| <ol> |
| <li>The Apache Thrift Compiler and Libraries, see <a href="/download">Download</a> and <a href="/docs/BuildingFromSource">Building from Source</a> for more details.</li> |
| <li>Generated the <a href="https://github.com/apache/thrift/blob/master/tutorial/tutorial.thrift">tutorial.thrift</a> and <a href="https://github.com/apache/thrift/blob/master/tutorial/shared.thrift">shared.thrift</a> files:<br> |
| <pre><code>thrift -r --gen as3 tutorial.thrift</code></pre> |
| </li> |
| <li>Followed all prerequisites listed below.</li> |
| </ol> |
| |
| <h3 id="prerequisites">Prerequisites</h3> |
| |
| <h3 id="client">Client</h3> |
| <p>To initialize client you can use code similar to:</p> |
| |
| <div class="highlight"><pre class="codehilite"><code> <span class="kd">private</span> <span class="n">function</span> <span class="nf">initConnection</span><span class="o">():</span><span class="kt">void</span> <span class="o">{</span> |
| <span class="n">mTransport</span> <span class="o">=</span> <span class="k">new</span> <span class="nc">TSocket</span><span class="o">(</span><span class="s">"127.0.0.1"</span><span class="o">,</span> <span class="mi">9090</span><span class="o">);</span> <span class="c1">// we connect to server</span> |
| <span class="n">mTransport</span><span class="o">.</span><span class="na">open</span><span class="o">();</span> |
| <span class="c1">// initialize protocol:</span> |
| <span class="kt">var</span> <span class="nl">protocol:</span><span class="nc">TProtocol</span> <span class="o">=</span> <span class="k">new</span> <span class="nc">TBinaryProtocol</span><span class="o">(</span><span class="n">mTransport</span><span class="o">,</span> <span class="kc">false</span><span class="o">,</span> <span class="kc">false</span><span class="o">);</span> |
| <span class="n">mCalculatorClient</span> <span class="o">=</span> <span class="k">new</span> <span class="nc">CalculatorImpl</span><span class="o">(</span><span class="n">protocol</span><span class="o">);</span> <span class="c1">// finally, we create calculator client instance</span> |
| <span class="o">}</span> |

| |
| <h3 id="server">Server</h3> |
| <p>The example client above can be tested against a java tutorial server.</p> |
| |
| <h3 id="additional-information">Additional Information</h3> |
| |
| <p>You might find server failing due to out of memory exception. This might happen because of flash crossdomain policy. See |
| next passage on how to fix this.</p> |
| |
| <h3 id="flash-crossdomain-policy">Flash crossdomain policy</h3> |
| |
| <p>Flash does not allow movies to connect to arbitrary servers. This is done for security reasons. To override this |
| restriction, however, servers’ owners can create special file - crossdomain xml file, which lists the rules according to |
| which some flash movies can connect to the server.</p> |
| |
| <p>Details about this behavior are listed in |
| <a href="http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html">Setting up a socket policy file server</a>. |
| Also, you can find a simple python/perl server script to serve this file there. For same host, you can serve |
| crossdomain.xml from any port. So, you can start your RPC servers on ports 9090 and 9091, and serve polisy file from |
| port 9092. To tell flash about this, you can use code from tutorial file:</p> |
| |
| <div class="highlight"><pre class="codehilite"><code> <span class="kd">private</span> <span class="n">function</span> <span class="nf">initSecurity</span><span class="o">():</span><span class="kt">void</span> <span class="o">{</span> |
| <span class="nc">Security</span><span class="o">.</span><span class="na">loadPolicyFile</span><span class="o">(</span><span class="s">"xmlsocket://127.0.0.1:9092"</span><span class="o">);</span> |
| <span class="o">}</span> |

| </p> |
| |
| <p>Example of crossdomain file, to allow connect to ports 9090 and 9091 from any server:</p> |
| |
| <pre><code> |
| <?xml version="1.0"?> |
| <!DOCTYPE cross-domain-policy SYSTEM "/xml/dtds/cross-domain-policy.dtd"> |
| <!-- Policy file --> |
| <cross-domain-policy> |
| <allow-access-from domain="*" to-ports="9090,9091" /> |
| </cross-domain-policy> |
