- 首先项目结构如下
myproject/
app.py
model1/
buleprint.py
templates/
index.html
static/
css/
style.css
img/
loading.png
js/
bootstrap.js
model2/
buleprint.py
templates/
static/
-
app.py:
from flask import Flask
from model1.buleprint import bp as b1
from model2.buleprint import bp as b2
app = Flask(__name__)
# 注册蓝图
app.register_blueprint(b1, url_prefix='/model1')
app.register_blueprint(b2, url_prefix='/model2')
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000, debug=True)
-
model1/buleprint.py:
from flask import Blueprint, render_template
# 蓝图实例化
bp = Blueprint('bp1', __name__)
@bp.route('/index', methods=['GET', 'POST'])
def index():
return render_template('index.html')
-
model2/buleprint.py:
from flask import Blueprint, render_template
# 蓝图实例化
bp = Blueprint('bp2', __name__)
@bp.route('/index', methods=['GET', 'POST'])
def index():
return render_template('index.html')
访问 http://127.0.0.1:5000/model1/index 或者 http://127.0.0.1:5000/model1/index 都是 error 404, templates not found。需要给蓝图指定 templates 和 static 的文件夹路径。即修改，
-
model1/buleprint.py:
bp = Blueprint('bp1', __name__,
template_folder='templates', # 指定蓝图加载的templates文件夹
static_folder='static' # # 指定蓝图加载的static文件夹
)
-
model2/buleprint.py:
bp = Blueprint('bp2', __name__,
template_folder='templates', # 指定蓝图加载的templates文件夹
static_folder='static' # # 指定蓝图加载的static文件夹
)
此时 index.html 能正常访问，但是 static 的静态文件还是访问 404。问题在于主应用 app 的 static 路径优先级会高于蓝图，应指定初始化app的static_folder = None，
-
app.py:
from flask import Flask
from model1.buleprint import bp as b1
from model2.buleprint import bp as b2
app = Flask(__name__, static_folder=None) # static_folder指定为空
# 注册蓝图
app.register_blueprint(b1)
app.register_blueprint(b2)
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000, debug=True)
-
model1/buleprint.py:
from flask import Blueprint, render_template
# 蓝图实例化
bp = Blueprint('bp1', __name__,
template_folder='templates', # 指定蓝图加载的templates文件夹
static_folder='static' # # 指定蓝图加载的static文件夹
)
@bp.route('/model1/index', methods=['GET', 'POST'])
def index():
return render_template('index.html')
-
model2/buleprint.py:
from flask import Blueprint, render_template
# 蓝图实例化
bp = Blueprint('bp2', __name__,
template_folder='templates', # 指定蓝图加载的templates文件夹
static_folder='static' # # 指定蓝图加载的static文件夹
)
@bp.route('/model2/index', methods=['GET', 'POST'])
def index():
return render_template('index.html')
templates 和 static 静态文件都正常访问。
