Api request query parameter case insensitive

Google Cloud Apigee
1

Hi,

I want to send a queryparam in the request which will work as case insensitive parameter, and I can use its value in some assign message policy.

I tried with all upper and all lower, but I need any letter in any case to work.

I don’t want to manually put all scenarios.

Any help is appreciated. Thanks in advance.

..which will work as case insensitive parameter,

Not clear.

Do you men to say that you want the value of the parameter to be treated case-insensitively? Eg foo?q=bar is the same as foo?q=BAR. ?

Or do you mean that you want the name of the parameter will be treated case-insensitively. Eg foo?q=bar is the same as foo?Q=bar ?

The former is easy with a {toUpperCase(request.queryparam.q)} in a message template.

For the latter you must use JavaScript to parse the query params and produce a hash of all lowercased parameters.

You can do it with the help of the URI.js module.

If you use that module, the code would look something like this.

var uri = URI(context.getVariable('request.uri'));
// get data map:
var search = uri.search(true);
// suppose the inbound API request looks like:
// [http://host/basepath/suffix?PARAM1=value1¶m2=value2](http://host/basepath/suffix?PARAM1=value1&param2=value2)
//
// then, the search object would look like this:
// {
//   "PARAM1": "value1",
//   "param2": "value2"
// }
var downcasedParams = {};
Object.keys(search).forEach(function (key) {
  downcasedParams[key.toLowerCase()] = search[key];
});
// you may need to be careful handling repeated query params.

I was asking for the second one. q and Q. I was asking for any solution other than scripting. I am having a 6 letters word as the query param.

I have the same issue here, have you found a way out?

nope, I had to use scripting. Didn’t get any option in availble policies.
