瓶GAE應用程序給錯誤

Question

我創建了這是工作的罰款pythonanywhere燒瓶中的應用程序，但是當我部署它在谷歌應用程序引擎，它給錯誤http://aapkatool.appspot.com/

這裏是我的代碼

from flask import Flask, request, session, redirect,url_for,render_template,flash,abort 
import jinja2 
import os 
jinja_environment = jinja2.Environment(autoescape=True, 
    loader=jinja2.FileSystemLoader(os.path.join(os.path.dirname(__file__), 'templates'))) 

app = Flask(__name__) 
app.config["DEBUG"] = True 
@app.route('/', methods=['POST', 'GET']) 
def emi(): 
    if request.method == 'POST': 

    p =int(request.form['enternumber1']) 
    r=float(request.form['enternumber2']) 
    R=(r/12)/100 
    N =int(request.form['enternumber3']) 
    Dp =int(request.form['enternumber4']) 
    P=p-Dp 
    B=(1+R)**N 
    I=(B)/(B-1) 

    EMI1 = (P) * (R) * (I) 
    EMI="%.2f" %(EMI1) 
    TAP1=EMI1*N 
    TAP="%.2f" %(TAP1) 
    TI=TAP1-P 
    TI="%.2f" %(TI) 



    return render_template('index.html', EMI=EMI,TAP=TAP,TI=TI,P=P,r=r,N=N,Dp=Dp) 
    return render_template('index.html') 

這裏是我的app.yaml代碼

application: aapkatool 
version: 1 
runtime: python27 
api_version: 1 
threadsafe: yes 

handlers: 
- url: /.* 
    script: initialize.app 

libraries: 
- name: jinja2 
    version: "2.6" 

- name: markupsafe 
    version: "latest" 

這裏是initialize.py代碼

from google.appengine.ext.webapp.util import run_wsgi_app 

from main import app 

run_wsgi_app(app) 

這裏是完整的錯誤

please help me why it is giving error. 

感謝

Answer 1

是在http://kk268.pythonanywhere.com/emi-calc和http://aapkatool.appspot.com/都部署定義的calculate功能？我看到在我的瀏覽器的唯一錯誤是：

(index):145 Uncaught ReferenceError: calculate is not defined 
onclick @ (index):145 

，我沒有看到calculate函數的定義在哪裏。

我不確定爲什麼你甚至有initialize.py文件。它看起來不像你需要它。 google.appengine.ext.webapp軟件包文檔聲明它適用於不推薦使用的Python 2.5環境，並且您正確使用Python 2.7。

1. 更改app.yaml的腳本處理程序，而不是指向main.app。
2. 刪除initialize.py。
3. 重新部署或更好的方法是，在本地測試您的代碼，以便在不必重新部署的情況下查看確切的錯誤代碼。如果只在部署的版本上發生，請進入logging area of the Cloud Console並展開失敗的請求以查看您需要修復的錯誤代碼和問題代碼。

帶Flask的示例啓動項目可以在here找到，Getting Started docs for App Engine with Python中也有引用。另外，如果您尚未獲得您的local development server running。
