This consists of three parts: 1. If the URL looks suspiciously like an archive, send a HEAD first to check the Content-Type is HTML or Simple API, to avoid downloading a large file. Raise `_NotHTTP` if the content type cannot be determined, or `_NotAPIContent` if it is not HTML or a Simple API. 2. Actually perform the request. Raise HTTP exceptions on network failures. 3. Check the Content-Type header to make sure we got a Simple API response, and raise `_NotAPIContent` otherwise. �rE zGetting page %sz, r= z*application/vnd.pypi.simple.v1+html; q=0.1ztext/html; q=0.01z max-age=0)�Acceptz Cache-Control)r> zFetched page %s as %sr; r< ) r r �filenamerR �logger�debugr r? �joinr rC r> )r" rE rQ r) r) r* �_get_simple_responsex s, ���� �rY )r> r# c C s< | r8d| kr8t j�� }| d |d< |�d�}|r8t|�S dS )z=Determine if we have any encoding information in our headers.r; z content-type�charsetN)�email�message�Message� get_paramr8 )r> �mrZ r) r) r* �_get_encoding_from_headers� s r` )�partr# c C s t j�t j�| ��S )zP Clean a "part" of a URL path (i.e. after splitting on "@" characters). )rI rJ �quote�unquote�ra r) r) r* �_clean_url_path_part� s re c C s t j�t j�| ��S )z� Clean the first part of a URL path that corresponds to a local filesystem path (i.e. the first part after splitting on "@" characters). )rI r@ � pathname2url� url2pathnamerd r) r) r* �_clean_file_url_path� s rh z(@|%2F))rN � is_local_pathr# c C s^ |r t }nt}t�| �}g }tt�|dg��D ]$\}}|�||�� |�|�� � q.d� |�S )z* Clean the path portion of a URL. � ) rh re �_reserved_chars_re�splitr � itertools�chain�append�upperrX )rN ri � clean_func�parts� cleaned_parts�to_clean�reservedr) r) r* �_clean_url_path� s rv c C s6 t j�| �}|j }t|j|d�}t j�|j|d��S )z� Make sure a link is fully quoted.
