# fix http headers, header could has same name key, but diff value.

http header could has same name key, but diff value.

• Closes Headers need same key  #38

[emilk]

This could return Vec<&str> or impl Iterator<Item = &str>.

The key should be &str

Also header_values is a better name (rust API:s don't use the get_ prefix for getters).

Suggested change

	/// Get `Header` list from request with the given key.
	pub fn get_header(&self, key: String) -> Vec<String> {
	self.headers
	.iter()
	.filter(|h| h.0 == key)
	.map(|h| h.1.clone())
	.collect()
	}
	/// Get `Header` list from request with the given key.
	pub fn header_values(&self, key: &str) -> impl Iterator<Item = &str> {
	self.headers
	.iter()
	.filter(|(name, _)| name == key)
	.map(|(_, value)| value.as_str())
	}
	/// Get the first matching header value for the given key.
	pub fn header_value(&self, key: &str) -> Option<&str> {
	self.header_values(key).next()
