为什么我的视图功能404？

Question

目录结构：

__init__：

from flask import flask 

app = Flask(__name__)


if __name__ == '__main__'
    app.run()

查看：

from app import app

@app.route('/')
def hello_world():
    return 'Hello World!'

我希望有人能解释我在这里做错了什么 - 我想我不明白如何正确导入app。这导致404.但是当视图移回__init__时，一切正常。

您需要在// When the user hits return, send the "text-entered" // message to main.js. // The message payload is the contents of the edit box. var textArea = document.getElementById("numTimes"); textArea.addEventListener('keyup', function onkeyup(event) { if (event.keyCode == 13) { // Remove the newline. text = textArea.value.replace(/(\r\n|\n|\r)/gm,""); self.port.emit("text-entered", text); textArea.value = ''; console.log("Got text from enter"); } }, false); // Listen for the "show" event being sent from the // main add-on code. It means that the panel's about // to be shown. // // Set the focus to the text area so the user can // just start typing. self.port.on("show", function onShow() { textArea.focus(); }); var submit = document.getElementById("search"); submit.addEventListener("click", function submit(){ text = textArea.value.replace(/(\r\n|\n|\r)/gm,""); self.port.emit("text-entered", text); textArea.value = ''; console.log("Got text from submit button"); }, false); 中明确导入views模块：

__init__

如果不导入模块，则永远不会进行视图注册。

将脚本部分保留在包外。在运行开发服务器的from flask import flask app = Flask(__name__) from . import views 中（因此在Final_app目录之外）添加单独的文件;说app：

run.py
