Question

我正在努力在httplib类上生成请求和响应。在这种情况下，我正在处理请求和响应字符串xml文件，以便我将一些请求发送到我的API服务器和服务器回复给我。基于sting xml格式的请求和响应。

当我使用错误的网址格式发送数据时，它会给我一个错误，我需要根据Traceback下面的内容引发异常：

2016-01-07 11:27:40,443 12180 ERROR dynaweld_15_09_15 openerp.netsvc: mismatched tag: line 1, column 959

    parser.Parse(string, True)

我曾尝试过以下方式来提高我的例外情况，但效果不佳。

任何帮助都非常感激：）
