Flask Windows Apache問題

Question

我試圖讓Flask在Windows上運行apache，並且遇到下面的錯誤消息。任何想法可能會導致這個問題？

錯誤消息：

我WSGI文件看起來像這樣：

import sys 
sys.path.insert(0, "c:\i4\importicus") 

from importicus import importicus_main as application 
application.debug = True 

和我的應用程序文件看起來像這樣：

from flask import Flask, render_template,jsonify, request 
from werkzeug import secure_filename 
import importicus_functions 
import ast, os, sys 
importicus_main = Flask(__name__) 

UPLOAD_FOLDER = 'uploads' 
TEMPLATE_FOLDER = 'templates' 
importicus_main.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER 
importicus_main.config['TEMPLATE_FOLDER'] = TEMPLATE_FOLDER 



@importicus_main.route('/') 
def application(environ, start_response): 
     status = '200 OK' 
     output = "Hello World! INSIDE" 
     response_headers = [('Content-type', 'text/plain'), 
          ('Content-Length', str(len(output)))] 
     start_response(status, response_headers) 
     return [output] 

Answer 1

主要的問題是你試圖寫WSGI，而不是Flask。 （瓶是比較容易的方式。）

這是你想要什麼：

@importicus_main.route('/') 
def application(): 
    return "Hello World! INSIDE" 

控制器（如應用功能）不帶參數，除非有您的網址字符串參數。一個例子是：

# /blog/1 would be a valid URL here 
@importicus_main.route('/blog/<int:post_id>') 
def blog_post(post_id): 
    return "This would be blog post number %s" % post_id 

看看燒瓶教程，如果你跳過它 - 這是非常好的。我還建議讓你的應用程序與內置的測試服務器一起運行。您可以稍後輕鬆移植到mod_wsgi（或其他）。
