When passed L{str}, header names (e.g. 'Content-Type') are encoded using ISO-8859-1 and header values (e.g. 'text/html;charset=utf-8') are encoded using UTF-8. Some methods that return values will return them in the same type as the name given. If the header keys or values cannot be encoded or decoded using the rules above, using just L{bytes} arguments to the methods of this class will ensure no decoding or encoding is done, and L{Headers} will treat the keys and values as opaque byte strings. @cvar _caseMappings: A L{dict} that maps lowercase header names to their canonicalized representation. @ivar _rawHeaders: A L{dict} mapping header names as L{bytes} to L{list}s of header values as L{bytes}. s Content-MD5s DNTs ETags P3Ps TEs WWW-Authenticates X-XSS-Protection)s content-md5s dnts etags p3ps tes www-authenticates x-xss-protectionN)� rawHeadersc C s0 i | _ |d ur,|�� D ]\}}| �||� qd S �N)� _rawHeaders�items� setRawHeaders)�selfr$ r �valuesr r r �__init__U s zHeaders.__init__)r c C s d� | jj| j�S )zR Return a string fully describing the headers set on this object. z{}({!r}))�format� __class__�__name__r& �r) r r r �__repr__^ s �zHeaders.__repr__c C s, t |t�r(tt| j�� �t|j�� ��S tS )zu Define L{Headers} instances as being equal to each other if they have the same raw headers. )� isinstancer# r �sortedr& r' �NotImplemented)r) �otherr r r �__cmp__g s �zHeaders.__cmp__r c C s t |t�r|�� �d�S |�� S )z� Encode the name of a header (eg 'Content-Type') to an ISO-8859-1 encoded bytestring if required. @param name: A HTTP header name @return: C{name}, encoded if required, lowercased z iso-8859-1)r1 �str�lower�encode�r) r r r r � _encodeNamer s zHeaders._encodeNamec C s | � | j�S )zg Return a copy of itself with the same headers set. @return: A new L{Headers} )r- r& r/ r r r �copy s z Headers.copyc C s | � |�| jv S )z� Check for the existence of a given header. @param name: The name of the HTTP header to check for. @return: C{True} if the header exists, otherwise C{False}. )r: r& r9 r r r � hasHeader� s zHeaders.hasHeaderc C s | j �| �|�d� dS )z� Remove the named header from this header object. @param name: The name of the HTTP header to remove. @return: L{None} N)r& �popr: r9 r r r � removeHeader� s zHeaders.removeHeader)r r* r c C s� t |t�s td|t|�f ��t |ttf�s>tdt|�f ��t|�D ]*\}}t |ttf�sFtd|t|�f ��qFt| �|��}g }|D ],}t |t�r�|� d�}n|}|� t|�� q�|| j |< dS )a� Sets the raw representation of the given header. @param name: The name of the HTTP header to set the values for. @param values: A list of strings each one being a header value of the given name. @raise TypeError: Raised if C{values} is not a L{list} of L{bytes} or L{str} strings, or if C{name} is not a L{bytes} or L{str} string. @return: L{None} zCHeader entry %r should be sequence but found instance of %r instead�2Header name is an instance of %r, not bytes or strzBHeader value at position %s is an instance of %r, not bytes or str�utf8N) r1 � _Sequence� TypeError�type�bytesr6 � enumerater" r: r8 �appendr& ) r) r r* �count�value�_nameZ encodedValues�v�_vr r r r( � s6 �� ���� zHeaders.setRawHeaders)r rH r c C sr t |ttf�s tdt|�f ��t |ttf�s@tdt|�f ��ttt | j|g d��}|� |� | � ||� dS )z� Add a new raw value for the given header. @param name: The name of the header for which to set the value. @param value: The value to set for the named header. r? z3Header value is an instance of %r, not bytes or str)�defaultN) r1 rD r6 rB rC r r r � getRawHeadersrF r( )r) r rH r* r r r � addRawHeader� s ��� zHeaders.addRawHeaderc C s d S r% r r9 r r r rM � s zHeaders.getRawHeaders)r rL r c C s d S r% r )r) r rL r r r rM � s c C s< | � |�}| j�|g �}|s |S t|t�r8dd� |D �S |S )a� Returns a sequence of headers matching the given name as the raw string given. @param name: The name of the HTTP header to get the values of. @param default: The value to return if no header with the given C{name} exists. @return: If the named header is present, a sequence of its values.
