Thanks for this post.

I’ve recently done something similar, but I’m trying to figure out how to handle errors for when calls are made with incorrect parameters. Currently my app throws a Zend_Json_Server_Error exception when there are missing parameters but doesn’t return it as a JSON-RPC response. Unfortunately it just spits the exception out as text.

Any thoughts about how to deal with this?

What I meant is my jsonrpc.php is as follows:
setClass(‘Simple’);

if (‘GET’ == $_SERVER[‘REQUEST_METHOD’]) {
// Indicate the URL endpoint, and the JSON-RPC version used:
$server->setTarget(‘/api/v1/jsonrpc.php’)
->setEnvelope(Zend_Json_Server_Smd::ENV_JSONRPC_2);

// Grab the SMD
$smd = $server->getServiceMap();

// Return the SMD to the client
header(‘Content-Type: application/json’);
echo $smd;
return;
}

$server->handle();

(the missing part compared to yours is already taken cared by my index.php)

Thanks for sharing.

I followed your article but I encountering “Internal Server Error” when I try to access /api/1.0/jsonrpc from the browser. Therefore, the Javascript script can’t work either.

I’m quite sure something is wrong with my .htaccess:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ – [NC,L]
RewriteRule ^api/([0-9].[0-9])/jsonrpc$ /api/$1/jsonrpc.php [NC,L]
RewriteRule ^.*$ index.php [NC,L]

And my bootstrap.php is as follows:
