I am working what appears to be a simple function for opensips 2.2.3, however cannot seem to get it working..
Essentially, extract the groupID from permissions module and add a prefix to R-URI on the egress side.
https://www.opensips.org/Documentation/Script-CoreFunctions-2-2#toc26
http://www.opensips.org/html/docs/modules/2.2.x/permissions.html#idp5689232
Config route looks like this:
route[relay] {
if ( get_source_group("$avp(group)") ) {
# do something with $avp(group)
xlog("group is $avp(group)\n");
};
#Add the string parameter in front of username in R-URI.
#prefix("$avp(group)");
#prefix("$avp(group){s.substr,0,0}");
$avp(22) = "3333#";
prefix("$avp(22)");
Prefix core function prefixes R-URI with variable name ($avp(22)) instead of value of "3333#".
I have tried various syntax versions that are commented out, however to no avail..
If I remove the quotes around the variable name:
prefix($avp(22));
Opensips does not startup at all, complaining about:
syntax error and bad argument, string expected
Am I missing something simple?
or
prefix function is simply not designed to work with variables?
Thank you in advance.
prefix() is somewhat old and unmaintained, hence it does not support variables. However, you can prepend your group to the R-URI username with:
$rU = $avp(group) + $rU;
xlog("My new R-URI is $ru. My new R-URI username is $rU\n");

I'm trying to use validate.js to validate input from the front end before entering it in the database with node but I'm getting an error that I can't figure out. I've gone over the docs and believe I setup the constraints correctly. The exact error is:
message:"Unknown validator pattern"
my validator is setup like this:
let alphanumeric = /^[a-zA-Z0-9]*$/;
let constraints = {
clientUsername:{
presence: true,
length: {min:8, max:15},
pattern:alphanumeric,
message: 'make sure client username is between 8-15 characters, is only numbers and letters'
},
tileCategory:{
presence:true,
length:{min:1, max:1},
numericality:{
onlyInteger:true,
lessThanOrEqualTo:tileCategoryNumber,
},
message:'enter a number, 1 char in length, less than or equal to 3' //the current number of tiles
}
};
validate({clientUsername: input.clientUsername},constraints);
At first I thought it was the regex pattern but tried commenting that out and then it said
message:"Unknown validator messsage"
so I'm guessing there is something wrong with my validator in general.
at the very top I of course included const validate = require('validate.js');
Something similar to this just burned me, have a look at the documentation again.
pattern is sort of a sub-validator of format and should look like:
{
format: {
pattern: "[A-Za-z0-9]+"
}
}
You're trying to use pattern at the "top level". I don't see anything in the documentation that implies helper patterns like alphanumeric exist. (I think the language the tool would use is to say "pattern is an option of the format validator" but I'm not sure.)
Your stated error message also implies a misspelling: it tells you it doesn't recognize messsage, which has 3 of the letter 's' but should have 2.
There's (2) things I could see being the issue. Firstly, you're using JS based regexes with the preceding and following /. Try removing these.
Beyond that, I'd recommend trying to remove the alphanumeric parameter & input the regex directly... it may be a type issue as well.
pattern:"^[a-zA-Z0-9]*$",
Hope this helps! :)
I setup OpenSips 2.3 proxy server, so any call come on server, my script grabs sip URI from DB, and forward call to that uri. When I get value I used AVP to get value and save it in $avp(didnumber), if I use rewrite with manually specifying uri it is working, but when I grab this value from DB and than assign it, it is not working in rewriteuri() method.
$ru = "sip:"+$avp(didnumber)
if I write
rewriteuri("[$ru]")
it throws following error
ERROR:core:parse_sip_msg_uri: bad uri <[$ru>
ERROR:tm:new_t: uri invalid
ERROR:tm:t_newtran: new_t failed
I think this method does not accept normal variable so I added quotation to make it string variable, now it shows fine on log but seem I have to convert variable using AVP or transformation, I tried many syntaxes but still could not do it. Please suggest.
rewrite_uri() has been deprecated in favour of simply using $ru. Your R-URI already gets completely rewritten by this statement:
$ru = "sip:" + $avp(didnumber);
However, note that the above is incorrect, since you do not supply a "hostport" part to the uri, according to the SIP RFC 3261:
SIP-URI = "sip:" [ userinfo ] hostport
uri-parameters [ headers ]
The parser will likely report an error. There are two fixes for this:
either only rewrite the R-URI "userinfo" part, like so:
$rU = $avp(didnumber);
supply a destination hostname:
$ru = "sip:" + $avp(didnumber) + "#" + $var(destination);
Following from here, you can just t_relay() using your new R-URI.
EDIT: the OpenSIPS URI parser will actually tolerate a URI such as "sip:44776772882", but it will interpret the DID as a hostname, so the errors may start appearing later, should the script writer attempt to relay the message to the invalid "44776772882" hostname.
I have a Geoserver WFS request with a cross layer filter based cql in it, that looks like this:
...&CQL_FILTER=INTERSECTS(the_geom, querySingle('myLayerName','the_geom','the_id = F338'))
This does not work. Geoserver is giving me this error message:
java.lang.NullPointerException: PropertyDescriptor is null - did you
request a property that does not exist?
if I change the filter to this:
&CQL_FILTER=INTERSECTS(the_geom, querySingle('myLayerName','the_geom','INCLUDE'))
it is working.
What could be going wrong in the first example? The id with the value F338 in fact does exist.
Could it be that Geoserver is expecting a integer as id? In CQL filters can be strings, but they have to be quoted. In my example, i obviously cannot really quote the value because the whole parameter to the querySingle function is a quote itself.
For string comparison, you need to put two single quotations, so i.e.
'the_id = ''F338'''. (one double quotation doesn't work)
This stupid undocumented little thing cost me 5 hours of try and error...
Scenario:
Consider the following code:
var querystring = require('querystring');
var ParamsWithValue = querystring.parse(req._url.query);
Then I am able to read any query string's value.
E.g: If requested string is http://www.website.com/Service.aspx?UID=Trans001&FacebookID=ae67ea324
I can get the values of query string with codes ParamsWithValue.UID & ParamsWithValue.FacebookID respectively.
Issue: I am able to get the values of any number of parameters passed in the same way described above. But for second time onwards I am getting the following error in response on browser.
Error:
{"code":"InternalError","message":"Cannot read property 'query' of undefined"}
Question: What is wrong in the approach to read the query string from the URL.
Note: I don't want to use any frameworks to parse it. I am trying to depend on built-in modules only.
Update: It responds correctly when the value of any of the parameter is changed. But if the same values requested again from even different browser it throws same error.
I think you need req.url rather than req._url.
req.url is a string, if you want a URI instance use require('url').parse(req.url)
So, you should finally have:
var ParamsWithValue = querystring.parse(require('url').parse(req.url).query);
Edit: I corrected a typo in point 1, the last req.url -> req._url
I need to redirect the URLs like this http://mysite.com/store/store-name to http://mysite.com/stores/products/store-id. Note that i need to get the store id from the database. So is it possible to do db operations in routes.php?
And in documentation the syntax is give as $route['store/:any']. How to get the value of second parameter here which is mentioned as :any.
There's not really any good nor simple way of running database queries through the routes. You can however have in the beginning of the controller function a validation.
I asume your store-name is some sort of slug for the product? Basicly you can validate if value is numeric or not, and if not find by slug and then redirect.
config/routes.php
$route["store/(.*)"] = 'stores/products/$1';
/* () and $1 together passes the values */
controllers/stores.php
/* Class etc. */
function products($mix) {
if (is_numeric($mix))
$int_id = $mix;
else {
$row = $this->get_where('products', array('slug' => $mix))->row();
$this->load->helper('url');
redirect("stores/products/{$row->id}");
}
/* Do stuff with the $int_id */
}
This asumes that you have:
A table named products
A column named id that's your products id
A column named slug that that's based on your store-name
I may be a little late to the party, but I may have an alternative suggestion.
I use the following for my routes:
http://mysite.com/store/1/store-name
Reason being... Based on your method, if you create
http://mysite.com/store/store-name
but then after a period of time (of which no doubt Google has indexed your page) you decide for what ever reason you have to change the name of the store to "Wonderful store name", you would naturally change your link to
http://mysite.com/store/wonderful-store-name
Which kills your SEO and any index links.
My solution of using http://mysite.com/store/1/store-name means that you can change store-name to anything you want, but it will always reference 1 meaning the user will still see the related page.
Anything is possible with CodeIgniter routes. Its all in the way you code it. Routing in CI is really flexible. You can use regular expressions besides the standard CI wildcards (:any)(:num). You can even add prefixes or suffixes to the path variables if you have to like:
$route['store/(:any)'] = "redircontroller/redirfunction/$1";
// for instance the namelookup method of the mystores controller
$route['stores/products/(:any)'] = "mystores/namelookup/$1";
You get the second parameter(and third and so on) by defining the variables in your route value which get passed to the controller method you define. If 'products' in you new url is also a variant you should start your wildcard expression there instead. You could also pull parameters out of the url using the URI class ($this->uri->segment(n)).
You don't, however, do database operations in routes.php. You do your database operations in the controller where you route to. My guess is that you'll have to match the store id using whatever is used in the url in a query.
In any case the path that you are using the routes file for is the path the user will see. To do the redirect you have to accept the original path and then redirect the user to the new path like so:
// in some controller that's attached to the original url
public function redirfunct($var){
$this->load->helper('url');
redirect(base_url('stores/products/' . $var));
}
I hope this helps you.
Yes that is easy, you only need to show the ID instead of the name,
you must be doing like storeName> Click to view details
Make it as
storeId> Click to view details
and when you are passing the parameter to the database, change the check of mysql, change it to id instead of name , that can be some like
" select yourRequiredColumn from table_name where id=".parameter."
Thanks
