我试图让 Flask 在 Windows 上运行 apache，我遇到了下面的错误消息。关于可能导致此问题的任何想法？

错误信息：

我的 WSGI 文件如下所示：

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

from importicus import importicus_main as application
application.debug = True

我的应用程序文件如下所示：

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]

主要问题是您正在尝试编写 WSGI，而不是 Flask。（烧瓶更容易。）

这就是你想要的：

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

控制器（如应用程序函数）不带参数，除非您的 url 字符串中有参数。一个例子是：

# /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

如果您跳过它，请查看 Flask 教程 - 它非常棒。我还建议让您的应用程序使用内置测试服务器运行。您可以稍后轻松移植到 mod_wsgi（或其他）。
