Issue: sequence in query and form extractors do not work

[AnderEnder]

Common multiple params usage in query and form can not be used with actix-web:

• example url: /index.html?first_name=John&last_name=Doe&emails=john%40example.com&emails=doe%40example.com
• example form body: first_name=John&last_name=Doe&emails=john%40example.com&emails=doe%40example.com

These are two test cases to represent the issue.

There is not much meaning with test case alone, but if I remember correctly we use serde_urlencoded to extract from query, so the functionality can be only added there

[AnderEnder]

Sure, these test case only represents the issues, the behaviour which is required, but not provided by actix-web. My expectation that web framework should support it. Currently I can not implement simple API and this stops the development.

AFAIK, serde_urlencoded does not want to support anything more, so the question to actix-web how to support it.

The issue is quite similar to #371, so the private serde_urlencoded was created as result.

the author of library did accept PR and we removed private fork. I think first step would be for us to write PR that implements this feature

[AnderEnder]

The author did not accept required feature. Related PR: nox/serde_urlencoded#42

We could switch to different library.

@AnderEnder you should understand, this is open source software and maintainers may not have free time to implement every feature. PR is always welcomed

[AnderEnder]

@fafhrd91, there is no similar library. And this is a common case(not feature) when a form submit multiple values.

@DoumanAsh and @fafhrd91
What do you suggest? Create a private fork here?

[DoumanAsh]

@AnderEnder There is serde_qs that was created to address this limitation it seems
