app.route和app.add_url_rule和藍圖

?

app.route方式：

源碼如下：

from flask import Flask app = Flask(__name__)@app.route("/") def hello():return "Hello World"@app.route("/my") def my():return "my page"if __name__ == "__main__":app.run(host = "0.0.0.0", debug=True)

運行截圖如下：

在路由中添加參數

from flask import Flask app = Flask(__name__)@app.route("/") def hello():return "Hello World"@app.route("/my/<user_name>") def my(user_name):return "my page %s" % (user_name)if __name__ == "__main__":app.run(host= "0.0.0.0", debug = True)

運行截圖如下：

通過app.add_url_rule方式

主要是綁定視圖函數和視圖類

如下代碼

from flask import Flask app = Flask(__name__)def hello():return "Hello World"def my(user_name):return "my page %s" % (user_name)app.add_url_rule(rule = "/", view_func = hello) app.add_url_rule(rule = "/my/<user_name>", view_func = my)if __name__ == "__main__":app.run(host = "0.0.0.0", debug=True)

運行截圖如下：

大型項目中都使用?藍圖?方式

如下代碼：

from flask import Flask, Blueprint app = Flask(__name__)index_page = Blueprint("index_page", __name__) @index_page.route("/") def index_page_index():return "index page"app.register_blueprint(index_page, url_prefix = "/it1995")@app.route("/") def hello():return "Hello World"if __name__ == "__main__":app.run(host = "0.0.0.0", debug=True)

運行截圖如下：

下面是分層的思想：

程序結構如下：

程序運行截圖如下：

源碼如下：

index_controller_1.py

from flask import Flask, Blueprintindex_1 = Blueprint("index_1", __name__) @index_1.route("/") def index_1_index():return "index page one"@index_1.route("/my") def index_1_my():return "index page one my"

index_controller_2.py

from flask import Flask, Blueprintindex_2 = Blueprint("index_2", __name__) @index_2.route("/") def index_2_index():return "index page two"

index_controller_3.py

from flask import Flask, Blueprintindex_3 = Blueprint("index_3", __name__) @index_3.route("/") def index_3_index():return "index page three"

index5.py

from flask import Flask from tie.index_controller_1 import index_1 from tie.index_controller_2 import index_2 from tie.index_controller_3 import index_3app = Flask(__name__)app.register_blueprint(index_1, url_prefix ="/it1995") app.register_blueprint(index_2, url_prefix ="/it1996") app.register_blueprint(index_3, url_prefix ="/it1997")if __name__ == "__main__":app.run(host = "0.0.0.0", debug=True)
