为了简化设置，请考虑在构建过程中使用Angular CLI将所有文件放置在分发目录中，即通过outputPath在angular.json中指定。您可以assets在构建期间使用angular.json部分移动您的Python文件。
"your-project": {
"root": "your-project-directory",
"sourceRoot": "your-project-directory/src",
"projectType": "application",
"architect": {
"build": {
"builder": "@angular-devkit/build-angular:browser",
"options": {
"outputPath": "dist",
"index": "your-project-directory/src/index.html",
"main": "your-project-directory/src/main.ts",
...
"assets": [
{
"glob": "**/*",
"input": "your-project-directory/src/assets/",
"output": "assets"
},
{
"glob": "**/*",
"input": "your-project-directory/src/python/",
"output": "."
}
在dist目录的顶层，将您main.py的基本Flask设置与一起放置index.html。注意 以确保提供支持文件。
from flask import Flask, send_from_directory
app = Flask(__name__)
@app.route('/<path:path>', methods=['GET'])
def static_proxy(path):
return send_from_directory('./', path)
@app.route('/')
def root():
return send_from_directory('./', 'index.html')
if __name__ == '__main__':
# This is used when running locally only. When deploying use a webserver process
# such as Gunicorn to serve the app.
app.run(host='127.0.0.1', port=8080, debug=True)
@app.errorhandler(500)
def server_error(e):
return 'An internal error occurred [main.py] %s' % e, 500
