500错误MySQLdb Python从表中提取数据时

我不确定为什么这段代码给了我一个与Flask的Web应用程序500错误，有人能告诉我我的逻辑错在哪里吗？我有一种感觉，它与sha256_crypt.verify（）函数有关，但不确定如何解决这个问题。试图从我的表中拉出用户的所有数据并将其放入会话变量中。让我知道，谢谢！500错误MySQLdb Python从表中提取数据时

异常从日志粘贴。 – jordanm

完成，对不起，我不知道这是否是发布错误日志的正确方法lol – douglasrcjames

您还没有设置mod_wsgi配置来告诉Python您的项目代码所在的位置。参见http://flask.pocoo.org/docs/0.12/deploying/mod_wsgi/ –

我解决了这个问题一段时间回来，想更新万一别人运行到这个职位。

因此，我所做的只是将c.execute()函数从sha256_crpt IF语句中取出，并将它们放在login重定向到的页面函数的开头。每个用户都会访问第一页，以便用户会话始终具有这些值。

这样：

@app.route('/ask/', methods=['GET','POST']) 
def ask(): 
    #clients come here first 
    error = '' 
    try: 
     c, conn = connection() 
     #grab all the clients info 
     email = session['email'] 
     c.execute("SELECT cid FROM clients WHERE email = (%s)", (thwart(email),)) 
     clientcid = c.fetchone()[0] 
     c.execute("SELECT phone FROM clients WHERE email = (%s)", (thwart(email),)) 
     phone = c.fetchone()[0] 
     c.execute("SELECT rating FROM clients WHERE email = (%s)", (thwart(email),)) 
     rating = c.fetchone()[0] 
     c.execute("SELECT first_name FROM cpersonals WHERE cid = (%s)", (clientcid,)) 
     first_name = c.fetchone()[0] 
     c.execute("SELECT last_name FROM cpersonals WHERE cid = (%s)", (clientcid,)) 
     last_name = c.fetchone()[0] 
     c.execute("SELECT address FROM cpersonals WHERE cid = (%s)", (clientcid,)) 
     address = c.fetchone()[0] 
     c.execute("SELECT city FROM cpersonals WHERE cid = (%s)", (clientcid,)) 
     city = c.fetchone()[0] 
     c.execute("SELECT state FROM cpersonals WHERE cid = (%s)", (clientcid,)) 
     state = c.fetchone()[0] 
     c.execute("SELECT zip FROM cpersonals WHERE cid = (%s)", (clientcid,)) 
     czip = c.fetchone()[0] 
     c.execute("SELECT reg_date FROM cpersonals WHERE cid = (%s)", (clientcid,)) 
     reg_date = c.fetchone()[0] 
     conn.commit() 
     c.close() 
     conn.close() 


     session['logged_in'] = 'client' 
     session['clientcid'] = clientcid 
     session['phone'] = phone 
     session['rating'] = rating 
     session['first_name'] = first_name 
     session['last_name'] = last_name 
     session['address'] = address 
     session['city'] = city 
     session['state'] = state 
     session['czip'] = czip 
     session['reg_date'] = reg_date
