从Flask运行NPM Build [英] Running NPM Build from Flask
问题描述
我有一个React前端，我想在我的python后端API相同的起源。我正在尝试使用Flask，但是我遇到了Flask没有找到我的静态文件的问题。
我的前端构建是使用 npm run build in saas_frontend
这里是我的文件结构看起来像：
├──main.py
├──requirements.txt
├── run.sh
├──saas_backend
├──saas_frontend
烧瓶是从> main.py 运行，并在 saas_frontend / build 中为前端服务：
├──asset-manifest.json
├──favicon.ico
├──index.html
├── manifest.json
├──service-worker.js
└──static
├──css
│├──main.096c9e23.css
│└ ──main.096c9e23.css.map
├──js
│├──main.8949f17a.js
│└── main.8949f17a.js.map
└──media
├──delta.56f5d855.csv
└──logo.e233ff84.png
我在 main.py 中声明了新模板路径和静态路径，如下所示：
7 import os $ b $ 8从flask导入Flask，render_template
9
10 template_dir = os.path .abspath（'saas_frontend / build /'）
11 static_dir = os.path.abspath（'saas_frontend / build / static'）
12 app = Flask（__ name__，static_path = static_dir，template_folder = template_dir）
13
14
15 @ app.route（'/'）
16 def index（）：
17 print template_dir
18 print static_dir
19 return render_template（'index.html'）
但是Flask仍然没有我服务我的静态文件，我得到这个作为输出....

<有什么我应该做的不同？如何解决错误信息中的路径正确的文件，但完全无法将其提供给浏览器？
谢谢!!
解决方案我解决了我的问题，通过使用符号链接到适当的文件和目录。
在我的构建脚本我将包括：
$ b $ pre $ lt; code> ln -s saas_frontend / build / static static
ln -s saas_frontend / build templates
现在一切正常！
I have a React front end that I would like to serve on the same origin as my python backend API. I'm trying to use Flask for this, but I'm running into an issue with Flask not finding my static files.
My front end build is generated with npm run build in saas_frontend
Here is what my file structure looks like:
├── main.py
├── requirements.txt
├── run.sh
├── saas_backend
├── saas_frontend
Flask is running from main.py and serving my front end in saas_frontend/build:
├── asset-manifest.json
├── favicon.ico
├── index.html
├── manifest.json
├── service-worker.js
└── static
├── css
│ ├── main.096c9e23.css
│ └── main.096c9e23.css.map
├── js
│ ├── main.8949f17a.js
│ └── main.8949f17a.js.map
└── media
├── delta.56f5d855.csv
└── logo.e233ff84.png
I declared the new template path and static path in main.py as follows:
7 import os
8 from flask import Flask, render_template
9
10 template_dir = os.path.abspath('saas_frontend/build/')
11 static_dir = os.path.abspath('saas_frontend/build/static')
12 app = Flask(__name__, static_path=static_dir, template_folder=template_dir)
13
14
15 @app.route('/')
16 def index():
17 print template_dir
18 print static_dir
19 return render_template('index.html')
But Flask is still unable to serve my static files and I get this as the output....
127.0.0.1 - - [21/Jul/2017 12:13:14] "GET / HTTP/1.1" 200 -
127.0.0.1 - - [21/Jul/2017 12:13:14] "GET /static/css/main.096c9e23.css HTTP/1.1" 404 -
127.0.0.1 - - [21/Jul/2017 12:13:14] "GET /static/js/main.8949f17a.js HTTP/1.1" 404 -
127.0.0.1 - - [21/Jul/2017 12:13:14] "GET /static/css/main.096c9e23.css HTTP/1.1" 404 -
127.0.0.1 - - [21/Jul/2017 12:13:14] "GET /static/js/main.8949f17a.js HTTP/1.1" 404 -
Is there anything I should be doing differently? How can Flask resolve the right file with path in the error message but be completely unable to serve it to the browser?
Thanks!!
I fixed my issue by using symlinks to the appropriate files and directories.
In my build script I will include:
ln -s saas_frontend/build/static static
ln -s saas_frontend/build templates
Everything works as expected now!
