M2Crypto：load_dynamic_engine() 的属性错误
我正在使用 M2Crypto-0.20.2。我想使用 OpenSC 项目中的 engine_pkcs11 和 Aladdin PKI 客户端进行基于令牌的身份验证，通过 ssl 进行 xmlrpc 调用。
我正在尝试加载 PKCS#11 引擎以及 Aladdin 模块（请参阅下面的代码）。但我收到一个错误： AttributeError: 'module' object has no attribute 'load_dynamic_engine'
from M2Crypto import SSL, m2
m2.load_dynamic_engine("dynamic","/usr/local/ssl/lib/engines/engine_pkcs11.so")
m2.load_dynamic_engine("pkcs11","/usr/lib/libeTPkcs11.so")
根据 M2Crypto 文档，此函数应该可用。这是我正在阅读的文档： http://www.heikkitoivonen.net/m2crypto/api/
任何人都可以向我指出正确的文档或帮助我弄清楚如何加载引擎吗？
谢谢！
I am using M2Crypto-0.20.2. I want to use engine_pkcs11 from the OpenSC project and the Aladdin PKI client for token based authentication making xmlrpc calls over ssl.
I am trying to load the PKCS#11 engine as well as the Aladdin module (see code below). But I get an error:
AttributeError: 'module' object has no attribute 'load_dynamic_engine'
from M2Crypto import SSL, m2
m2.load_dynamic_engine("dynamic","/usr/local/ssl/lib/engines/engine_pkcs11.so")
m2.load_dynamic_engine("pkcs11","/usr/lib/libeTPkcs11.so")
According to the M2Crypto documentation, this function should be available. This is the documentation I'm reading: http://www.heikkitoivonen.net/m2crypto/api/
Can anyone point me to the correct documentation or help with figuring out how to load the engines?
Thanks!

我自己没有使用过Engine模块，所以无法给你任何明确的答案。但是，您应该查看 test_engine.py 模块以了解一些信息指针。我猜测要加载 OpenSSL 提供的引擎，您不应该使用
load_dynamic_engine()的形式，而应该使用load_dynamic()或load_openssl().您可能仅在加载第 3 方模块时才需要load_dynamic_engine()。I haven't used the Engine module myself, so I cannot give you any definite answers. However, you should take a look at test_engine.py module for some pointers. I am guessing that to load engines provided by OpenSSL you shouldn't use that form of
load_dynamic_engine(), but eitherload_dynamic()orload_openssl(). You'd probably needload_dynamic_engine()only when loading 3rd party modules.我读错了文档。 load_dynamic_engine() 属于 Engine 模块。
我更改了命令，现在出现了不同的错误：
Engine.load_dynamic_engine("dynamic","/usr/local/ssl/lib/engines/engine_pkcs11.so")
错误的引擎 ID
Engine.load_dynamic_engine("动态","/usr/local/ssl/lib/engines/engine_pkcs11.so")
文件“/usr/local/lib/python2.4/site-packages/M2Crypto/Engine.py”，第 92 行，位于 load_dynamic_engine
e.ctrl_cmd_string("LOAD", 无)
文件“/usr/local/lib/python2.4/site-packages/M2Crypto/Engine.py”，第 38 行，在 ctrl_cmd_string 中
引发 EngineError(Err.get_error())
M2Crypto.Engine.EngineError：23541：错误：260B606D：引擎例程：DYNAMIC_LOAD：初始化失败：eng_dyn.c：521：
知道这意味着什么吗？
I was reading the documentation wrong. The load_dynamic_engine() belong in the Engine module.
I changed the command and now get a different error:
Engine.load_dynamic_engine("dynamic","/usr/local/ssl/lib/engines/engine_pkcs11.so")
bad engine id
Engine.load_dynamic_engine("dynamic","/usr/local/ssl/lib/engines/engine_pkcs11.so")
File "/usr/local/lib/python2.4/site-packages/M2Crypto/Engine.py", line 92, in load_dynamic_engine
e.ctrl_cmd_string("LOAD", None)
File "/usr/local/lib/python2.4/site-packages/M2Crypto/Engine.py", line 38, in ctrl_cmd_string
raise EngineError(Err.get_error())
M2Crypto.Engine.EngineError: 23541:error:260B606D:engine routines:DYNAMIC_LOAD:init failed:eng_dyn.c:521:
Any idea what this means?
