Flask 0.11 发布了，Flask 是一个微型的 Python 开发的 Web 框架，示例代码：
@app.route("/") def hello(): return "Hello World!"
Added support to serializing top-level arrays to
flask.jsonify. This introduces a security risk in ancient browsers. Seejson-securityfor details.
Added before_render_template signal.
flask.Test.test_clientto support passing additional keyword arguments to the constructor of
SESSION_REFRESH_EACH_REQUESTconfig key that controls the set-cookie behavior. If set to
Truea permanent session will be refreshed each request and get their lifetime extended, if set to
Falseit will only be modified if the session actually modifies. Non permanent sessions are not affected by this and will always expire if the browser window closes.
Made Flask support custom JSON mimetypes for incoming data.
Added support for returning tuples in the form
(response, headers)from a view function.
Templates are no longer automatically reloaded outside of debug mode. This can be configured with the new
Added a workaround for a limitation in Python 3.3's namespace loader.
Added support for explicit root paths when using Python 3.3's namespace packages.
flask.climodule to start the local debug server through the click CLI system. This is recommended over the old
flask.run()method as it works faster and more reliable due to a different design and also replaces
Error handlers that match specific classes are now checked first, thereby allowing catching exceptions that are subclasses of HTTP exceptions (in
werkzeug.exceptions). This makes it possible for an extension author to create exceptions that will by default result in the HTTP error of their choosing, but may be caught with a custom error handler if desired.
Flask will now log by default even if debug is disabled. The log format is now hardcoded but the default log handling can be disabled through the
Removed deprecated module functionality.
EXPLAIN_TEMPLATE_LOADINGconfig flag which when enabled will instruct Flask to explain how it locates templates. This should help users debug when the wrong templates are loaded.
Enforce blueprint handling in the order they were registered for template loading.
Ported test suite to py.test.
request.jsonin favour of
Add "pretty" and "compressed" separators definitions in jsonify() method. Reduces JSON response size when JSONIFY_PRETTYPRINT_REGULAR=False by removing unnecessary white space included by default after separators.
JSON responses are now terminated with a newline character, because it is a convention that UNIX text files end with a newline and some clients don't deal well when this newline is missing. Seehttps://github.com/pallets/flask/pull/1262 -- this came up originally as a part of https://github.com/kennethreitz/httpbin/issues/168
