Support array field for Request DTO

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

It supports array field object in the api specification right now, and it should be work in controller

GetVersionReq {
		Statuses                     []string   `form:"statuses[],omitempty,optional"`
}

unfortunately, it doesn't work because there is a tiny mass in httpx package. The form.Get method only return one string rather than string array

Describe the solution you'd like
A clear and concise description of what you want to happen.

we should not use the Get method directly if we wanna support array field..... btw, I am curiose why Go design the method like this. It make no sense....right?

Get(key string) string

Alternatively, I will access the map directly like what saying in the comment

I found this PR flawed. see #4015 (comment)

bug url example:

"/a?name=hello&age=18&percent=3.4&statuses=try"

error parse statuses is nil, instead of []string{"try"}.

预期:[]string{"try"}
实际:[]string(nil)
