Zope2 XML-RPC与AT Image mutator之间的互动不良? [英] Bad interaction between Zope2 XML-RPC and AT Image mutator?

问题描述

我正在为mr.migrator创建演示，并且遇到了一个令人烦恼的问题，在此处展示:

I am creating a demo for mr.migrator and have run in to an annoying problem, showcased here:

# create image
proxy = xmlrpclib.ServerProxy(url) # reset
data = open('screenshot.png').read()
try:
    proxy.invokeFactory('Image', 'screenshot.png')
except xmlrpclib.ProtocolError:
    print sys.exc_info()[1]
except xmlrpclib.Fault:
    print "The id is invalid - it is already in use." # most likely
proxy = xmlrpclib.ServerProxy(url + '/screenshot.png')
proxy.setTitle('This is an image')
try:
    proxy.setImage(data) # XXX this fails
except:
    print sys.exc_info()[1]

此代码应使用来自图像的数据填充图像字段，但失败的原因是:

This code should populate the image field with data from the image, but instead it fails consistently with:

<ProtocolError for admin:admin@localhost:8080/Plone/screenshot.png: 500 Internal Server Error>

更糟糕的是，这就是Zope2所说的.在前台运行Plone时，我没有看到任何回溯或其他任何指示问题的信息.

Worse, this is all Zope2 says. I don't see any tracebacks or anything else that indicates a problem when running Plone in the foreground.

下一步是什么?您可以在此处签出并重现此内容:

What's my next step? You can check out and reproduce this here:

我将以常规"方式执行此操作，并将关键字参数传递给invokeFactory，但 XML-RPC不支持它们.

I would do this the "normal" way, with keyword arguments passed to invokeFactory, but XML-RPC does not support them.

推荐答案

这很可能是特殊字符错误. xml-rpc协议可以使用允许您使用的任何字符XML.您应该尝试将图像数据包装在Binary包装器中:

This is most likely a special character error. The xml-rpc protocol can use any character XML allows you to use. You should try to wrap the image data in a Binary wrapper:

wrappedData = xmlrpclib.Binary(open('screenshot.png').read())
