奇怪的GAE Python编码问题

我想从Twitter获取推文，并通过GTalk使用GAE中的xmpp API发送它。我有一个很奇怪的问题。奇怪的GAE Python编码问题

我有成功检索到来自Twitter的数据。使用XMPP API发送错误时发生错误。根据跟踪信息，错误发生在GAE代码中，而不是我自己的。我已经用Python2.5测试了特定的推文，并且它能够正确处理推文文本，并且推文仅包含英文字符。

''ascii'编解码器无法解码字节0xca' – Kjuly

有点偏离主题：有问题与twitter和GAE afaik。 Twitter会按域进行限制 - 如果您使用的是appspot，则与其他正在与appspot上的twitter进行交谈的应用程序共享有限的资源 - 我们发现很难处理这些资源。不知道它是否仍然如此。 –

它们通过IP进行节制，而不是域，虽然效果是相同的：App引擎请求池在一起，并被视为一个非常繁忙的应用程序。如果这是问题，你可能会得到一个DownloadError而不是UnicodeDecodeError。 –
