Appending value to set-cookie header in beresp. in Varnish 2.1 - header

The case is I'd like to add two headers with the same name, but different values while processing response from the backend server. More precisely under certain circumstances I'd like to append (not set) another Set-Cookie header to the original response from my Apache server to eventually return two cookies to the client. It seems that "set" action overrides all occurrences of the same header.
Is that possible?

VCL doesn't have an explicit string concatenation operator. However, you can concatenate values by setting them to a variable:
set req.http._message = "one string", " a second string"
which can then be assigned to other values or used however.
In your particular case, you should be able to do something like this:
if (some-condition) {
set beresp.http.Set-Cookie = beresp.http.Set-Cookie, "my second cookie";
}

You can use regsub() or regsuball() for the manipulation of HTTP headers.
https://www.varnish-cache.org/docs/2.1/reference/vcl.html
Edit:
off the top of my head, it should look similar to the following
set beresp.http.Set-Cookie = regsub(beresp.http.Set-Cookie, "^(.+)$", "\1; secure; httponly");

Does gorm interpret the content of a struct with a logical OR?

New to SQL, I am writing as an exercise an API middleware that checks if the information contained in some headers match a database entry ("token-based authentication"). Database access is based on GORM.
To this, I have defined my ORM as follows:
type User struct {
ID uint
UserName string
Token string
}
In my middleware I retrieve the content of relevant headers and end up with the variables userHeader and tokenHeader. They are supposed to be matched to the database in order to do the authentication.
The user table has one single entry:
select * from users
// 1,admin,admintoken
The authentication code is
var auth User
res := db.Where(&User{UserName: userHeader, Token: tokenHeader}).Find(&auth)
if res.RowsAffected == 1 {
// authentication succeeded
}
When testing this, I end up with the following two incorrect results (other combinations are correct):
with only one header set to a correct value (and the other one not present) the authentication is successful (adding the other header with an incorrect value is OK (=auth fails))
no headers set → authentication goes though
I expected my query to mean (in the context of the incorrect results above)
select * from users where users.user_name = 'admin' and users.token = ''
select * from users where users.user_name = '' and users.token = ''
and this query is correct on the console, i.e. produces zero results (ran against the database).
The ORM one, however, seems to discard non-existing headers and assume they are fine (this is at least my understanding)
I also tried to chain the Where clauses via
db.Where(&User{UserName: userHeader}).Where(&User{Token: tokenHeader}).Find(&auth)
but the result is the same.
What should be the correct query?
The gorm.io documentation says the following on the use of structs in Where conditionals:
When querying with struct, GORM will only query with non-zero fields,
that means if your field’s value is 0, '', false or other zero
values, it won’t be used to build query conditions ...
The suggested solution to this is:
To include zero values in the query conditions, you can use a map,
which will include all key-values as query conditions ...
So, when the token header or both headers are empty, but you still want to include them in the WHERE clause of the generated query, you need to use a map instead of the struct as the argument to the Where method.
db.Where(map[string]interface{}{"user_name": userHeader, "token": tokenHeader}).Find(&auth)
You can use Debug() to check for the generated SQL (it gets printed into stderr); use it if you are unsure what SQL your code generates

How to create a correct filter string with OR and AND operators for django?

My app has a frontend on vue.js and backend on django rest framework. I need to do a filter string on vue which should do something like this:
((status=closed) | (status=canceled)) & (priority=middle)
but got an error as a response
["Invalid querystring operator. Matched: ') & '."]
After encoding my string looks like this:
?filters=((status%3D%D0%97%D0%B0%D0%BA%D1%80%D1%8B%D1%82)%20%7C%20(status%3D%D0%9E%D1%82%D0%BA%D0%BB%D0%BE%D0%BD%D0%B5%D0%BD))%20%26%20(priority%3D%D0%A1%D1%80%D0%B5%D0%B4%D0%BD%D0%B8%D0%B9)
which corresponds to
?filters=((status=closed)|(status=canceled))&(priority=middle)
How should look a correct filter string for django?
I have no problem if statement includes only | or only &. For example filter string like this one works perfect:
?filters=(status%3D%D0%97%D0%B0%D0%BA%D1%80%D1%8B%D1%82)%20%7C%20(status%3D%D0%9E%D1%82%D0%BA%D0%BB%D0%BE%D0%BD%D0%B5%D0%BD)
a.k.a. ?filters=(status=closed)|(status=canceled). But if i add an & after it and additional brackets to specify the order of conditions calculation it fails with an error.
I also tried to reduce usage of brackets and had string like this (as experiment):
?filters=(status%3D%D0%97%D0%B0%D0%BA%D1%80%D1%8B%D1%82%20%7C%20status%3D%D0%9E%D1%82%D0%BA%D0%BB%D0%BE%D0%BD%D0%B5%D0%BD)
a.k.a. ?filters=(status=closed | status=canceled). This one doesn't work - get neither error nor the data.
I need to have a mixed results in my case: both statuses (closed and canceled) and priority=middle, but a string format isn't correct. Please explain, which format would be Ok?
That doesn't look like a very uri friendly syntax you're trying to use there.
Try doing this instead:
?status[]=closed&status[]=cancelled&priority=middle
Then use request.GET.getlist('status[]') to get back the list and use the values for logical OR queryset filtering:
qs = qs.filter(status__in=request.GET.getlist('status[]', [])
and then add any additional filtering which works as logical AND.
If you're using axios, it should automatically format js status url param into proper format.

Query parameter handling in karate framework

Is there any easy way to handle huge query param like below. Also I would like to know how can I do run time parameterisation for some values?

Yes. Read the docs: https://github.com/intuit/karate#param
For example:
* param callBackType = 'NetVerifyId'
and so on. And look at params where you can set all keys up as one single JSON and also do parameterization if needed, there are multiple possibilities: https://github.com/intuit/karate#params
See this example as well: dynamic-params.feature

Can Karate generate multiple query parameters with the same name?

I need to pass multiple query parameters with the same name in a URL, but I am having problems getting it to work with Karate. In my case, the URL should look like this:
http://mytestapi.com/v1/orders?sort=order.orderNumber&sort=order.customer.name,DESC
Notice 2 query parameters named "sort". I attempted to create these query string parameters with Karate, but only the last "sort" parameter gets created in the query string. Here are the ways I tried to do this:
Given path 'v1/orders'
And param sort = 'order.orderNumber'
And param sort = 'order.customer.name,DESC'
And header Authorization = authInfo.token
And method get
Then status 200
And:
Given path 'v1/orders'
And params sort = { sort: 'order.orderNumber', sort: 'order.customer.name,DESC' }
And header Authorization = authInfo.token
And method get
Then status 200
And:
Given path 'v1/order?sort=order.orderNumber&sort=order.customer.name,DESC'
And header Authorization = authInfo.token
And method get
Then status 200
The first two ways provide the same query string result: ?sort=order.customer.name%2CDESC
The last example does not work because the ? get encoded, which was expected and explained in this post - Karate API Tests - Escaping '?' in the url in a feature file
It's clear that the second "sort" param is overriding the first and only one parameter is being added to the URL. I have gone through the Karate documentation, which is very good, but I have not found a way to add multiple parameters with the same name.
So, is there a way in Karate to set multiple URL query parameters with the same name?
Yes you can generate multiple query parameters with the same name in karate
All values of similar key should be provided in an array.
Given path 'v1/orders'
And params {"sort":["order.orderNumber","order.customer.name,DESC"]}
And header Authorization = authInfo.token
And method get
Then status 200
And for setting single parameter using param it will be like
And param sort = ["order.orderNumber","order.customer.name,DESC"]

Play reverse routing - getting absolute url

How can I get the absolute URL in play 2.2 scala when doing the following:
val promoLink = routes.Promotions.promotionsCategory(DOCID, slug)
//routes file
GET /promotions/:DOCID:/slug controllers.Promotions.promoCat(DOCID, slug)
As it stands I get a "found : play.api.mvc.Call" type mismatch on expecting a string
thanks
I suppose your promoLink should be a String containing an URL? Your question sounds a bit unclear.
If so then you probably need this:
val promoLink = routes.Promotions.promotionsCategory(DOCID, slug).absoluteURL(false)(request)
false in the .absoluteURL(false) stands for the isSecure parameter which will give you http or https url.
If you have an implicit request in scope you may omit the last (request) part
