Refit: Dynamic querystring!

[RaminMT]

Hi,
I've got an endpoint which has about 15 query string parameters for filtering purposes. As they are optional parameters, there will be a lot of parameter combination so overloads are useless and Also I should avoid setting null-value parameters as it does affect on the result.
I searched a little seems implementing IUrlParameterFormatter is the answer, but I don't have any idea of how to.
Would somebody guide me on this?!

Thanks
Ramin

Isn't this: https://github.com/paulcbetts/refit#form-posts what you want?

[RaminMT]

No, mine is a GET request & the parameters are query string parameters

[Cheesebaron]

It shouldn't matter that yours is a GET. If you look at the example it is converted into query string parameters.

[Cheesebaron]

So:

public interface IDerpApi
{
    [Get("/durr")]
    Task Herp([Body(BodySerializationMethod.UrlEncoded)] Dictionary<string, object> stuff);
}

var stuff = new Dictionary<string, object> {
    {"herpy", 1}, 
    {"derpy", "bar"}, 
    {"doo", new Guid("d1e9ea6b-2e8b-4699-93e0-0bcbd26c206c")}
};

This should give:

/durr?herpy=1&derpy=bar&doo=d1e9ea6b-2e8b-4699-93e0-0bcbd26c206c

Thank you, I tried that but no success.

[Cheesebaron]

What does "no success" mean?

Does it crash? Does it give a malformatted url? something else? Do you want people to guess?

[RaminMT]

No success means I didn't get the desired result!!
I expected that to narrow the results but it didn't go that way. I also sniffed the request using fiddler & saw that It has body just like it's a post request not the way you said according to documentations.

[bennor]

That dictionary support is really for APIs that take form posts (where the data goes in the request body and the content type is application/x-www-form-urlencoded.

We could possibly extend the querystring parameter generation to work with a dictionary though.

[RaminMT]

@bennor Well, thank you.
Extending to work with dictionary as #252? Would you please teach me by code or explain it more?

Thanks

[RaminMT]

Friends, No comment on this? I really don't have any idea.

[bennor]

Sorry. I'll try to have a look this weekend.

[RaminMT]

Thanks man that would be appreciated, Hope you get back with good news.

[bennor]

Hey, I've had a quick look into it and I can't see how it's possible without changes. I'll see if I can get a PR together to add support over the next week.

I had a look at #252, but I have no idea what it's about. There's no interface in Refit called IRequestQueryParamSerializer, but a Google search for it brought up RestEase.

[RaminMT]

Thank you dear,
I also checked what he said but I didn't find the interface, Also emailed to Paul for help on that but no response.
For now I'm not referencing Refit using Nuget, So if you share your changes with me, I can test it well & use it until your PR will available soon.

[ravensorb]

That was my bad. I forgot i switched over to reastease as i needed this same functionality.

[RaminMT]

Hi,
@bennor What's the new bro?! Is there any chance?

[bennor]

Completely dropped.off the radar, sorry. Will take a look at it this weekend.

[RaminMT]

Tnx, I hope you come up with great news 😄

[RaminMT]

Hey @bennor
Did you find any solution on this?!

[bennor]

Not yet. Too much going on in the rest of my life. I should be able commit to having it completed by mid September. Sorry to string you along.

[RaminMT]

Tnx buddy
Is there any temporary solution for me? Now I made an static method to make the request but I need it to be fixed soon so I can release my app.

[bennor]

If you change control over the API you could change it to accept a form post and use the form body serialization method. Otherwise you'll need to provide static versions of the parameters. Can you make some optional?

[RaminMT]

I don't have control over the api unfortunately. Also static parameters can't help me, because I have some sort of array in parameters like below:
123=456&123From=4&567To=8
These three parameters are completely dynamic. They can be repetitive & has permutations

[napalm684]

Any update when we might see this? I have a similar problem where I cannot control the api. Things get further complicated when its a multipart request with additional form data. I found the api will accept the items as query string parameters but one of the two I need to pass is a dynamic value. A workaround till the Query attribute is available would be helpful if anyone has figured that out?

Hi, any update of this?
