A. 怎么使用python flask搭建静态服务器

Frozen-Flask freezes aFlaskapplication into a set of static files. The result can be hosted without any server-side software other than a traditional web server.

Note:This project used to be called Flask-Static.

Installation

Install the extension with one of the following commands:

$ easy_install Frozen-Flask

or alternatively if you have pip installed:

$ pip install Frozen-Flask

or you can get thesource code from github.

Context

This documentation assumes that you already have a workingFlaskapplication. You can run it and test it with the development server:

from myapplication import appapp.run(debug=True)

Frozen-Flask is only about deployment: instead of installing Python, a WGSI server and Flask on your server, you can use Frozen-Flask tofreezeyour application and only have static HTML files on your server.

Getting started

Create aFreezerinstance with yourappobject and call itsfreeze()method. Put that in afreeze.pyscript (or call it whatever you like):

from flask_frozen import Freezerfrom myapplication import appfreezer = Freezer(app)if __name__ == '__main__':
freezer.freeze()

This will create abuilddirectory next to your application’, with your application’s content frozen into static files.

Note

Frozen-Flask considers it “owns” its build directory. By default, it willsilently overwritefiles in that directory, andremovethose it did not create.

Theconfigurationallows you to change the destination directory, or control what files are removed if at all.

This build will most likely be partial since Frozen-Flask can only guess so much about your application.

Finding URLs

Frozen-Flask works by simulating requests at the WSGI level and writing the responses to aptly named files. So it needs to find out which URLs exist in your application.

The following URLs can be found automatically:

• Static files handled by Flask for your application or any of itsblueprints.

• Views with no variable parts in the URL, if they accept theGETmethod.

• New in version 0.6:Results of calls toflask.url_for()made by your application in the request for another URL. In other words, if you useurl_for()to create links in your application, these links will be “followed”.

This means that if your application has an index page at the URL/(without parameters) and every other page can be found from there by recursively following links built withurl_for(), then Frozen-Flask can discover all URLs automatically and you’re done.

Otherwise, you may need to write URL generators.

URL generators

Let’s say that your application looks like this:

• @app.route('/')def procts_list():


• return render_template('index.html', procts=models.Proct.all())@app.route('/proct_<int:proct_id>/')def proct_details():


• proct = models.Proct.get_or_404(id=proct_id)


• return render_template('proct.html', proct=proct)



If, for some reason, some procts pages are not linked from another page (or these links are not built byurl_for()), Frozen-Flask will not find them.

To tell Frozen-Flask about them, write an URL generator and put it after creating yourFreezerinstance and before callingfreeze():

• @freezer.register_generatordef proct_details():


• for proct in models.Proct.all():


• yield {'proct_id': proct.id}



Frozen-Flask will find the URL by callingurl_for(endpoint,**values)whereendpointis the name of the generator function andvaluesis each dict yielded by the function.

You can specify a different endpoint by yielding a(endpoint,values)tuple instead of justvalues, or you can by-passurl_forand simply yield URLs as strings.

Also, generator functions do not have to bePython generatorsusingyield, they can be any callable and return any iterable object.

All of these are thus equivalent:

• @freezer.register_generatordef proct_details(): # endpoint defaults to the function name


• # `values` dicts


• yield {'proct_id': '1'}


• yield {'proct_id': '2'}@freezer.register_generatordef proct_url_generator(): # Some other function name


• # `(endpoint, values)` tuples


• yield 'proct_details', {'proct_id': '1'}


• yield 'proct_details', {'proct_id': '2'}@freezer.register_generatordef proct_url_generator():


• # URLs as strings


• yield '/proct_1/'


• yield '/proct_2/'@freezer.register_generatordef proct_url_generator():


• # Return a list. (Any iterable type will do.)


• return [


• '/proct_1/',


• # Mixing forms works too.


• ('proct_details', {'proct_id': '2'}),


• ]



Generating the same URL more than once is okay, Frozen-Flask will build it only once. Having different functions with the same name is generally a bad practice, but still work here as they are only used by their decorators. In practice you will probably have a mole for your views and another one for the freezer and URL generators, so having the same name is not a problem.

Testing URL generators

The idea behind Frozen-Flask is that you canuse Flask directlyto develop and test your application. However, it is also useful to test yourURL generatorsand see that nothing is missing, before deploying to a proction server.

You can open the newly generated static HTML files in a web browser, but links probably won’t work. TheFREEZER_RELATIVE_URLSconfigurationcan fix this, but adds a visibleindex.htmlto the links. Alternatively, use therun()method to start an HTTP server on the build result, so you can check that everything is fine before uploading:

• if __name__ == '__main__':


• freezer.run(debug=True)



Freezer.run()will freeze your application before serving and when the reloader kicks in. But the reloader only watches Python files, not templates or static files. Because of that, you probably want to useFreezer.run()only for testing the URL generators. For everything else use the usualapp.run().

Flask-Scriptmay come in handy here.

Controlling What Is Followed

Frozen-Flask follows links automatically or with some help from URL generators. If you want to control what gets followed, then URL generators should be used with the Freezer’swith_no_argument_rulesandlog_url_forflags. Disabling these flags will force Frozen-Flask to use URL generators only. The combination of these three elements determines how much Frozen-Flask will follow.

Configuration

Frozen-Flask can be configured using Flask’sconfiguration system. The following configuration values are accepted:

• FREEZER_BASE_URL

• Full URL your application is supposed to be installed at. This affects the output offlask.url_for()for absolute URLs (with_external=True) or if your application is not at the root of its domain name. Defaults to'http://localhost/'.

• FREEZER_RELATIVE_URLS

• If set toTrue, Frozen-Flask will patch the Jinja environment so thaturl_for()returns relative URLs. Defaults toFalse. Python code is not affected unless you userelative_url_for()explicitly. This enables the frozen site to be browsed without a web server (opening the files directly in a browser) but appends a visibleindex.htmlto URLs that would otherwise end with/.

  New in version 0.10.

• FREEZER_DEFAULT_MIMETYPE

• The MIME type that is assumed when it can not be determined from the filename extension. If you’re using the Apache web server, this should match theDefaultTypevalue of Apache’s configuration. Defaults toapplication/octet-stream.

  New in version 0.7.

• FREEZER_IGNORE_MIMETYPE_WARNINGS

• If set toTrue, Frozen-Flask won’t show warnings if the MIME type returned from the server doesn’t match the MIME type derived from the filename extension. Defaults toFalse.

  New in version 0.8.

• FREEZER_DESTINATION

• Path to the directory where to put the generated static site. If relative, interpreted as relative to the application root, next to . Defaults tobuild.

• FREEZER_REMOVE_EXTRA_FILES

• If set toTrue(the default), Frozen-Flask will remove files in the destination directory that were not built ring the current freeze. This is intended to clean up files generated by a previous call toFreezer.freeze()that are no longer needed. Setting this toFalseis equivalent to settingFREEZER_DESTINATION_IGNOREto['*'].

  New in version 0.5.

• FREEZER_DESTINATION_IGNORE

• A list (defaults empty) offnmatchpatterns. Files or directories in the destination that match any of the patterns are not removed, even ifFREEZER_REMOVE_EXTRA_FILESis true. As in.gitignorefiles, patterns apply to the whole path if they contain a slash/, to each slash-separated part otherwise. For example, this could be set to['.git

B. 如何在pycharm 中搭建 flask 环境

1、使用virtualenvwrapper或者virtualenv的话，则更换虚拟环境的时候需要设置一下
2、具体方法是File--->Settings，然后选择Project Interpreter，下拉框选择对应的路径即可。若系统中有多个版本的Python也是用这种方法“配置”的。

F. 如何使用阿里云搭建flask 网站

静态服务器直接使用Nginx就行了。
flask主要是写动态的，也就是有交互，有数据库存储的这种。

G. flask框架有什么用

Flask是一个使用 Python 编写的轻量级 Web 应用框架。其 WSGI 工具箱采用 Werkzeug ，模板引擎则使用 Jinja2 。
Flask使用 BSD 授权。Flask也被称为 “microframework” ，因为它使用简单的核心，用 extension 增加其他功能。Flask没有默认使用的数据库、窗体验证工具。
web网站发展至今，特别是服务器端，涉及到的知识、内容，非常广泛，这对程序员的要求会越来越高的。如果采用成熟，稳健的框架，那么一些基础的工作，比如说安全性，数据流控制等都可以让框架来处理，那么程序开发人员就可以将精力放在具体的业务逻辑上面。
使用框架的优势：稳定性、可扩展性强，可以降低开发效率，提高开发效率。
而Flask框架是Python的web框架，最大特征就是轻便，让开发者自由灵活的兼容开发的feature。Python语言灵活性给予了Flask框架同样的特征，无论用户画像还是产品推荐，Python对比其他语言都有很大的优势。
另外Flask框架轻便，容易上手，试错成本低，搭建网站的时候，Flask框架是最好的选择。

H. 【Python基础】flask框架是用来干什么的

你可以用来开发网站服务器，它包含一个wsgi工具包（werkzeug）、 模板引擎（jinja2）还有主体（flask）。

安装方式:

1. 打开命令行
2. 输入命令
3. 命令是"pip install flask"

J. 如何理解Flask

Flask 是一种具有平缓学习曲线和庞大社区支持的微框架，利用它可以构建大规模的web应用。是搭建社区平台的神器之一。 利用它可以构建大规模的web应用。学习上手Flask非常轻松，但要深入理解却并不容易。本书从一个简单的Flask应用开始，通过解决若干实战中的问题，对一系列进阶的话题进行了探讨。书中使用MVC（模型-视图-控制器）架构对示例应用进行了转化重构，以演示如何正确地组织应用代码结构。有了可扩展性强的应用结构之后，接下来的章节使用Flask扩展为应用提供了额外的功能，包括用户登录和注册、NoSQL查询、REST API、一套后台管理界面，以及其他特性。然后，你会学到如何使用单元测试，保障代码持续按照正确的方式工作，避免极具风险的猜测式编程。 一个简单的Flask 项目入手，由浅入深地探讨了一系列实战问题，包括如何使用SQLAlchemy 和Jinja 等工具进行Web 开发；如何正确地设计扩展性强的Flask 应用架构和搭建MVC 环境；对于各种NoSQL 数据库的特性，何时应该、何时不应该及如何使用它们；通过使用Flask 扩展快速实现用户的身份系统、RESTful API、NoSQL查询、后台管理等功能；如何创建自己的扩展；使用Celery 编写异步任务，使用pytest 进行单元测试等；最后介绍了如何部署上线，包括使用自己搭建的服务器或使用各种云服务，以及如何权衡和选择这些不同的解决方案。
