| 57 | Simple HTTP request handler</A> |
| 58 | </H1> |
| 59 | |
| 60 | <P> |
| 61 | <A NAME="module-SimpleHTTPServer"></A> |
| 62 | |
| 63 | <P> |
| 64 | The <tt class="module">SimpleHTTPServer</tt> module defines a request-handler class, |
| 65 | interface-compatible with <tt class="class">BaseHTTPServer.BaseHTTPRequestHandler</tt>, |
| 66 | that serves files only from a base directory. |
| 67 | |
| 68 | <P> |
| 69 | The <tt class="module">SimpleHTTPServer</tt> module defines the following class: |
| 70 | |
| 71 | <P> |
| 72 | <dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline"> |
| 73 | <td><nobr><b><span class="typelabel">class</span> <tt id='l2h-3605' xml:id='l2h-3605' class="class">SimpleHTTPRequestHandler</tt></b>(</nobr></td> |
| 74 | <td><var>request, client_address, server</var>)</td></tr></table></dt> |
| 75 | <dd> |
| 76 | This class is used to serve files from the current directory and below, |
| 77 | directly mapping the directory structure to HTTP requests. |
| 78 | |
| 79 | <P> |
| 80 | A lot of the work, such as parsing the request, is done by the base |
| 81 | class <tt class="class">BaseHTTPServer.BaseHTTPRequestHandler</tt>. This class |
| 82 | implements the <tt class="function">do_GET()</tt> and <tt class="function">do_HEAD()</tt> functions. |
| 83 | </dl> |
| 84 | |
| 85 | <P> |
| 86 | The <tt class="class">SimpleHTTPRequestHandler</tt> defines the following member |
| 87 | variables: |
| 88 | |
| 89 | <P> |
| 90 | <dl><dt><b><tt id='l2h-3606' xml:id='l2h-3606' class="member">server_version</tt></b></dt> |
| 91 | <dd> |
| 92 | This will be <code>"SimpleHTTP/" + __version__</code>, where <code>__version__</code> |
| 93 | is defined in the module. |
| 94 | </dl> |
| 95 | |
| 96 | <P> |
| 97 | <dl><dt><b><tt id='l2h-3607' xml:id='l2h-3607' class="member">extensions_map</tt></b></dt> |
| 98 | <dd> |
| 99 | A dictionary mapping suffixes into MIME types. The default is signified |
| 100 | by an empty string, and is considered to be <code>application/octet-stream</code>. |
| 101 | The mapping is used case-insensitively, and so should contain only |
| 102 | lower-cased keys. |
| 103 | </dl> |
| 104 | |
| 105 | <P> |
| 106 | The <tt class="class">SimpleHTTPRequestHandler</tt> defines the following methods: |
| 107 | |
| 108 | <P> |
| 109 | <dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline"> |
| 110 | <td><nobr><b><tt id='l2h-3608' xml:id='l2h-3608' class="method">do_HEAD</tt></b>(</nobr></td> |
| 111 | <td><var></var>)</td></tr></table></dt> |
| 112 | <dd> |
| 113 | This method serves the <code>'HEAD'</code> request type: it sends the |
| 114 | headers it would send for the equivalent <code>GET</code> request. See the |
| 115 | <tt class="method">do_GET()</tt> method for a more complete explanation of the possible |
| 116 | headers. |
| 117 | </dl> |
| 118 | |
| 119 | <P> |
| 120 | <dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline"> |
| 121 | <td><nobr><b><tt id='l2h-3609' xml:id='l2h-3609' class="method">do_GET</tt></b>(</nobr></td> |
| 122 | <td><var></var>)</td></tr></table></dt> |
| 123 | <dd> |
| 124 | The request is mapped to a local file by interpreting the request as |
| 125 | a path relative to the current working directory. |
| 126 | |
| 127 | <P> |
| 128 | If the request was mapped to a directory, the directory is checked for |
| 129 | a file named <code>index.html</code> or <code>index.htm</code> (in that order). |
| 130 | If found, the file's contents are returned; otherwise a directory |
| 131 | listing is generated by calling the <tt class="method">list_directory()</tt> method. |
| 132 | This method uses <tt class="function">os.listdir()</tt> to scan the directory, and |
| 133 | returns a <code>404</code> error response if the <tt class="function">listdir()</tt> fails. |
| 134 | |
| 135 | <P> |
| 136 | If the request was mapped to a file, it is opened and the contents are |
| 137 | returned. Any <tt class="exception">IOError</tt> exception in opening the requested |
| 138 | file is mapped to a <code>404</code>, <code>'File not found'</code> |
| 139 | error. Otherwise, the content type is guessed by calling the |
| 140 | <tt class="method">guess_type()</tt> method, which in turn uses the |
| 141 | <var>extensions_map</var> variable. |
| 142 | |
| 143 | <P> |
| 144 | A <code>'Content-type:'</code> header with the guessed content type is |
| 145 | output, followed by a blank line signifying the end of the headers, |
| 146 | and then the contents of the file are output. If the file's MIME type |
| 147 | starts with <code>text/</code> the file is opened in text mode; otherwise |
| 148 | binary mode is used. |
| 149 | |
| 150 | <P> |
| 151 | For example usage, see the implementation of the <tt class="function">test()</tt> |
| 152 | function. |
