Aplikasi selalunya perlu menyediakan fail statik seperti JavaScript, imej dan CSS selain mengendalikan permintaan dinamik. Apl dalam persekitaran fleksibel boleh menyampaikan fail statik daripada pilihan Google Cloud seperti Cloud Storage, menyampaikannya secara langsung atau menggunakan rangkaian penghantaran kandungan pihak ketiga (CDN)

## Menyediakan fail daripada Cloud Storage
Storan Awan boleh mengehoskan aset statik untuk apl web dinamik. Faedah menggunakan Storan Awan dan bukannya menyiarkan terus daripada apl anda termasuk:
- Cloud Storage pada asasnya berfungsi sebagai rangkaian penghantaran kandungan. Ini tidak memerlukan sebarang konfigurasi khas kerana secara lalai sebarang objek boleh dibaca dicache dalam rangkaian Storan Awan global

- Muatan apl anda akan dikurangkan dengan memunggah aset statik siaran ke Storan Awan. Bergantung pada bilangan aset statik yang anda miliki dan kekerapan akses, ini boleh mengurangkan kos menjalankan apl anda dengan jumlah yang besar

- Caj lebar jalur untuk mengakses kandungan selalunya boleh kurang dengan Cloud Storage

Anda boleh memuat naik aset anda ke Storan Awan dengan menggunakan
alat baris arahan gsutil
atau Cloud Storage API

Pustaka Pelanggan Awan Google menyediakan klien idiomatik kepada Storan Awan, untuk menyimpan dan mendapatkan semula data dengan Storan Awan dalam apl Enjin Apl

 Contoh penyajian daripada baldi Storan Awan
Contoh mudah ini mencipta baldi Storan Awan dan memuat naik aset statik menggunakan Google Cloud CLI:
Buat baldi. Adalah perkara biasa, tetapi tidak diperlukan, untuk menamakan baldi anda selepas ID projek anda. Nama baldi mestilah unik di peringkat global

gsutil mb gsyour-bucket-name>Tetapkan ACL untuk memberikan akses baca kepada item dalam baldi

gsutil defacl set public-read gsyour-bucket-name>Muat naik item ke baldi. The
rsynccommand biasanya merupakan cara terpantas dan paling mudah untuk memuat naik dan mengemas kini aset. Anda juga boleh menggunakan
cp

gsutil -m rsync -r ./static gsyour-bucket-name>/static
Anda kini boleh mengakses aset statik anda melalui
httpsstorage.googleapis.com//static

 Serving files from other Google Cloud services
You also have the option of using Cloud CDN or other Google Cloud storage services

## Serving files directly from your app
Serving files from your app is typically straightforward, however, there are a couple drawbacks that you should consider:
- Requests for static files can use resources that otherwise would be used for dynamic requests


- Depending on your configuration, serving files from your app can result in response latency, which can also affect when new instances are created for handling the load

 Example of serving static files with your app
 Go
In Go, you can use the standard
http.FileServer
or
http.ServeFile
to serve files directly from your app

// Package static demonstrates a static file handler for App Engine flexible environment. package main import ( "fmt" "net/http" "google.golang.org/appengine" ) func main() { // Serve static files from "static" directory. http.Handlestatic http.FileServer(http.Dir http.HandleFunc homepageHandler) appengine.Main() } const homepage = doctype html>   Static Files /main.css">   
This is a static file serving examplep> 
   Static Files /styles.css">   
This is a static file serving examplep> 
 default 
doctype html html(lang="en") head title Static Files meta(charset='utf-8') link(rel="stylesheet", hrefstatic/main.css") body p This is a static file serving example

The stylesheet itself is located at
./public/css, which is served from
/static/main.css

body { font-family: Verdana, Helvetica, sans-serif; background-color: #CCCCFF; }
Other Node.js frameworks, such as Hapi, Koa, and Sails typically support serving static files directly from the application. Refer to their documentation for details on how to configure and use static content

 PHP
The PHP runtime runs nginx
to serve your app, which is configured to serve static files in
your project directory. You must declare the document root by specifying
document_root in your
app.yaml file:
runtime: php env: flex runtime_config: document_root: web
 Python
Most web frameworks include support for serving static files. In this sample,
the app uses Flask's built-in ability
to serve files in
./static directory from the
/static URL

The app includes a view that renders the template. Flask automatically
serves everything in the
./static directory without additional configuration

import logging from flask import Flask, render_template app = Flaskname @app.route def hello return render_template('index.html') @app.errorhandler(500) def server_error(e): logging.exception('An error occurred during a request returnAn internal error occurred:  See logs for full stacktrace. format(e), 500 if __name__ == main # This is used when running locally. Gunicorn is used to run the # application on Google App Engine. See entrypoint in app.yaml. app.run(host='127.0.0.1', port=8080, debug=True)
The template rendered by the view includes a stylesheet located at
/static/main.css

   Static FilesFlask automatically makes files in the 'static' directory available via '/static'./main.css">   
This is a static file serving examplep> 

doctype html html head title Serving Static Files link rel="stylesheet" hrefapplication.css" script srcapplication.js" body p This is a static file serving example

The stylesheet is located at
./public/application.css which is served
from
/application.css

body { font-family: Verdana, Helvetica, sans-serif; background-color: #CCCCFF; }
 Ruby on Rails
The Ruby on Rails
web framework serves files from the
./public directory by default. Static
JavaScript and CSS files can also be generated by the Rails asset
pipeline

This example app has a layout view that includes all the app's stylesheets:
doctype html html head title Serving Static Files = stylesheet_link_tag "application", media: "all" = javascript_include_tag "application" = csrf_meta_tags body = yield
The stylesheet itself is a
Sass file located
at
./app/assets/stylesheets/main.css.sass

body font-family: Verdana, Helvetica, sans-serif background-color: #CCCCFF
By default, Rails apps do not generate or serve static assets when running in production

The Ruby runtime executes
rake assets:precompile during deployment
to generate static assets and sets the
RAILS_SERVE_STATIC_FILES environment
variable to enable static file serving in production

 .NET
