在这里尝试下面的代码，它应该给你一个良好的开端。

// requrires 3 arguments
// user, project, path
// usage e.g: [bitbucket user="jespern" project="django-piston" path="piston/utils.py"]
function bitbucket_code( $atts ) {
    extract( $atts );
    global $post;
    $path_to_name = str_replace("/", "_", $path);
    $meta_key = "bitbucket_{$user}_{$project}_{$path_to_name}";
    $code = get_post_meta( $post->ID, $meta_key, true );
    if ( !$code ) {
        $bitbucket_url = "https://api.bitbucket.org/1.0/repositories/$user/$project/raw/tip/$path";
        // just in case its not there ;)
        if( !class_exists( \'WP_Http\' ) )
                include_once( ABSPATH . WPINC. \'/class-http.php\' );
        $request = new WP_Http();
        $response = $request->request( $bitbucket_url );
        $code = htmlentities( $response[\'body\'] );
        update_post_meta( $post->ID, $meta_key, $code );
    }
    return \'<pre>\'. $code . \'</pre>\';
}               
add_shortcode(\'bitbucket\', \'bitbucket_code\');

您可以使用WP Bucket 用于插件或主题。
