Associative container mapping `String` keys to `String` values.
|
|
|
|
`StringMap` is an alias for `std::map<String, String>`.
|
|
|
|
## Common Uses
|
|
|
|
`StringMap` commonly appears in:
|
|
|
|
- `context.params`
|
|
- `context.get`
|
|
- `context.post`
|
|
- `context.cookies`
|
|
- `context.session`
|
|
- `context.header`
|
|
|
|
Because it uses `std::map`, `map["key"]` will create an empty entry when that key does not already exist.
|
|
|
|
Helpers such as `parse_query()` and `encode_query()` convert between query strings and `StringMap` values.
