MySQL Asterisk AGI - ValueError: Could not process parameters
MySQL Asterisk AGI - ValueError: Could not process parameters
所以我已经对这个问题进行了一分钟的故障排除，奇怪的是它似乎 运行 在独立的 Python 脚本中很好，但是当移动到星号 AGI 时我收到以下错误：
cursor.execute(query, (res))
File "/usr/local/lib/python2.7/dist-packages/mysql/connector/cursor_cext.py", line 248, in execute
prepared = self._cnx.prepare_for_mysql(params)
File "/usr/local/lib/python2.7/dist-packages/mysql/connector/connection_cext.py", line 615, in prepare_for_mysql
raise ValueError("Could not process parameters")
下面是 运行 引发此错误的相关数据。

cursor.execute(query, (res))
cursor.close()
cnx.close()
注意：number_br=3，技术上应该是 number_br=%s，但为了排除故障，我替换为静态变量。整个脚本在旧版本的 CentOS 上运行，我正试图让它在 Debian 服务器上运行。
编辑：正如 arheops 适当指出的那样，此查询在 res 变量方面存在问题，因为它不是字符串，解决方案最终是更改变量在查询中的包含方式，请参见下面的示例带来了解决方案
query = ("select active,address,rent,deposit,phone,pets_allow,smoker_allow,section_8,garage,attached_garage,fenced_yard,carport,shed,patio,deck,basement,garden_area,of$
query = ("select active,address,rent,deposit,phone,calldialog,id from activelisting where active=1 and number_br={} order by id".format(res))
cursor.execute(query)
cursor.execute 接受字符串，而不是元组作为参数。

变量 res 根本不是字符串。
