HttpHeader

public struct HttpHeader
extension HttpHeader: Equatable
extension HttpHeader: Hashable
extension HttpHeader: ExpressibleByDictionaryLiteral

This struct is used to represent a header of HTTP requests. It can contain arbitrarily many fields which are each defined by a key and a value. The key is of the type HttpHeader.Field. The value always needs to be of type String.

Inner Type

  • A header field represents the key for a specific entry in the HTTP header. There exist some pre-defined header fields that are used frequently (e.g. Content-Type) which are exposed via static variables. The user may add additional static variables here to provide a safe way for using header fields. Header fields can also be (transparently) initialized via strings, i.e. anywhere where a header field is required, the user may simply pass a String. Nonetheless, the usage of static variables is encouraged to prevent needless typos.

Operators

  • Combines the fields of two different headers into a single header containing all fields. Whenever a field occurs in both headers, the value of the second header is used.
