python - 将 django pyodbc 应用程序转换为 apache 时出现 odbc 连接错误

Question

我尝试了以下修复： https ://code.google.com/p/pyodbc/issues/detail?id=214

我仍然得到同样的错误。

关于如何补救这种情况的任何想法？

# To be able to use the functionality of a module which was built as a DSO you

# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.

# Example:
# LoadModule foo_module modules/mod_foo.so

另一种方法是嵌入连接字符串，而不是在代码之外维护 DSN。您需要使用连接字符串语法，但这里有一些东西可以开始（我正在使用pyodbc.connect文档中定义的字符串和关键字的混合）：

cnxn = pyodbc.connect('system=<insert system name';dbq='PRODDTA',
                      driver='{iSeries Access ODBC Driver}',
                      uid='<insert user name>', pwd='<insert password>')

我发现这种方法使不可避免的代码迁移更容易。

您需要将 DSN 设置为系统 DSN，因为 Apache 用户是“系统”用户，并且将查看系统 DSN 而不是用户 DSN。

pyodbc 的这个连接字符串对我有用：

conexion_str = 'SYSTEM=%s;db2:DSN=%s;UID=%s;PWD=%s;DRIVER=%s;' % (self._SYSTEM, self._DSN, self._UID, self._PWD, self._DRIVER)
cnn = pyodbc.connect(conexion_str)
