前端发起http请求 '/getData' ,项目就卡死

index.py 代码如下：

from flask import Flask,render_template,request
import json
import pymssql
import urllib.parse
import sys
app = Flask(__name__)

@app.route('/')
def index():
    return render_template('index.html')
@app.route('/hello')
def hello():
    return 'hello world'
@app.route('/getData',methods=['GET'])
def getddlData(): 
    # return json.dumps([])
    sql='SELECT DISTINCT ChatRoomName FROM dbo.Issue'
    conn=pymssql.connect(host="localhost", user="sa", password="123456", database="IssueCollect") 
    cursor=conn.cursor(as_dict=True) 
    cursor.execute(sql)
    rooms=cursor.fetchall()
    cursor.close()
    conn.close()
    return json.dumps(rooms) 
if __name__ == '__main__':
    app.run()

test.wsgi：

import sys
#app's path
sys.path.insert(0,"C:/Users/Stephen/Desktop/IssueCollect")
from index import app
#Initialize WSGI app object
application = app

Apache conf

LoadFile "c:/program files (x86)/python37-32/python37.dll"
LoadModule wsgi_module "c:/program files (x86)/python37-32/lib/site-packages/mod_wsgi/server/mod_wsgi.cp37-win32.pyd"

    WSGIScriptAlias / C:/Users/Stephen/Desktop/IssueCollect/test.wsgi
    <Directory C:/Users/Stephen/Desktop/IssueCollect>

卡死后关闭httpd，查看Apache error log：

在本地python中执行index.py访问正常，
发布到Apache服务器上，不连接数据库直接返回空正常。
连接数据库就有问题。
是我Apache配置问题吗？
