It is used to efficiently match WSGI requests against a number of routes and return the first target that satisfies the request. The target may be anything, usually a string, ID or callable object. A route consists of a path-rule and a HTTP method. The path-rule is either a static path (e.g. `/contact`) or a dynamic path that contains wildcards (e.g. `/wiki/<page>`). The wildcard syntax and details on the matching order are described in docs:`routing`. z[^/]+r� �c Fc sR g � _ i � _i � _i � _i � _i � _|� _� fdd�dd� dd� dd� d�� _d S )Nc s t | p � j�d d fS r )r� �default_pattern��confra r" r# r7 3 s z!Router.__init__.<locals>.<lambda>c S s dt dd� fS )Nz-?\d+c S s t t| ��S r )�str�intr5 r" r" r# r7 5 r2 �3Router.__init__.<locals>.<lambda>.<locals>.<lambda>)r� r� r" r" r# r7 5 r2 c S s dt dd� fS )Nz-?[\d.]+c S s t t| ��S r )r� �floatr5 r" r" r# r7 6 r2 r� )r� r� r" r" r# r7 6 r2 c S s dS )N)z.+?NNr" r� r" r" r# r7 7 r2 )r� r� r� �path)�rules�_groups�builder�static� dyna_routes� dyna_regexes� strict_order�filters)rb r\ r" ra r# r{ ) s �zRouter.__init__c C s || j |< dS )z� Add a filter.

Additional keyword arguments are added to the list of headers. Underscores in the header name are replaced with dashes. �� r� )r� )r� �Content-EncodingzContent-Languager� � Content-Ranger� z Content-Md5� Last-Modified)r� r� r� Nc K st d | _ i | _|| _|p| j| _|rNt|t�r4|�� }|D ]\}}| �||� q8|rp|�� D ]\}}| �||� qZd S r ) �_cookies�_headersrM �default_statusrK rV ru r rL )rb rM rK r� � more_headersr! r� r" r" r# r{ � s zBaseResponse.__init__c C sX |pt }|� }| j|_tdd� | j�� D ��|_| jrTt� |_|j�| jjdd�� |S )z Returns a copy of self. c s s" | ]\}}||d d � fV qd S r r" �r� �k�vr" r" r# r� � r2 z$BaseResponse.copy.<locals>.<genexpr>r� )r� ) r' rK ru r- r r, r@ rs �output)rb r� r r" r" r# r � s zBaseResponse.copyc C s t | j�S r )r� rM ra r" r" r# r� � s zBaseResponse.__iter__c C s t | jd�r| j�� d S )Nrc )rJ rM rc ra r" r" r# rc � s zBaseResponse.closec C s | j S )z; The HTTP status line as a string (e.g. ``404 Not Found``).�r� ra r" r" r# � status_line� s zBaseResponse.status_linec C s | j S )z/ The HTTP status code as an integer (e.g. 404).)r� ra r" r" r# r� � s zBaseResponse.status_codec C s� t |t�r |t�|� }}n*d|v r>|�� }t|�� d �}ntd��d| krZdksdn td��|| _t|pvd| �| _ d S )N� r z+String status line without a reason phrase.r� i� zStatus code out of range.z %d Unknown) rV r� �_HTTP_STATUS_LINESr� rl rY r� r� r� r� )rb rK r� r" r" r# � _set_status� s zBaseResponse._set_statusc C s | j S r r4 ra r" r" r# � _get_status s zBaseResponse._get_statusaQ A writeable property to change the HTTP response status.

If the `secret` parameter is set, create a `Signed Cookie` (described below). :param name: the name of the cookie. :param value: the value of the cookie. :param secret: a signature key required for signed cookies. Additionally, this method accepts all RFC 2109 attributes that are supported by :class:`cookie.Morsel`, including: :param max_age: maximum age in seconds. (default: None) :param expires: a datetime object or UNIX timestamp. (default: None) :param domain: the domain that is allowed to read the cookie. (default: current domain) :param path: limits the cookie to a given path (default: current path) :param secure: limit the cookie to HTTPS connections (default: off). :param httponly: prevents client-side javascript to read this cookie (default: off, requires Python 2.6 or newer). If neither `expires` nor `max_age` is set (default), the cookie will expire at the end of the browser session (as soon as the browser window is closed). Signed cookies may store any pickle-able object and are cryptographically signed to prevent manipulation. Keep in mind that cookies are limited to 4kb in most browsers. Warning: Signed cookies are not encrypted (the client can still see the content) and not copy-protected (the client can restore an old cookie). The main intention is to make pickling and unpickling save, not to store secret information at client side. z)Secret key missing for non-string Cookie.i zCookie value to long.�max_age� i �expires�%a, %d %b %Y %H:%M:%S GMTr� r N)r, r@ rG � cookie_encoderV rX rc r� r� r r ZsecondsZdays�datedater Z timetupler� r� �time�gmtime�strftimer )rb r! r� r� r\ ry r" r" r# � set_cookieN s& ! zBaseResponse.set_cookiec K s( d|d< d|d< | j |dfi |�� dS )zq Delete a cookie.

Keys and values are native strings (2.x bytes or 3.x unicode) and keys are case-insensitive. If the WSGI environment contains non-native string values, these are de- or encoded using a lossless 'latin1' character set. The API will remain stable even on changes to the relevant PEPs. Currently PEP 333, 444 and 3333 are supported.
