问题 I am having a problem with a misbehaving HTTP Proxy server. I have no control over the proxy server, unfortunately -- it's an 'enterprise' product from IBM. The proxy server is part of a service virtualization solution being leveraged for software testing. The fundamental issue (I think*) is that the proxy server sends back HTTP/1.0 responses.

问题 I'm trying to search the world wide web for this answer, but I feel there answer may be no. I'm using Python 3.5 and a library called urllib.request with a method called urllib.request.urlopen(url) to open a link and download a file. It would be nice to have some kind of measure of progress for this, as the file(s) are over 200MB. I'm looking at the API here, and don't see any kind of parameter with a hook. Here's my code: downloadURL = results[3] #got this from code earlier up rel_path =

问题 I'm upgrading a module from odoo v10 to odoo v11. It is founded that the get_action is replaced with report_action. so I used the code as follows self.env.ref('report_action_name').report_action(self, data=data, config=False) but it gives me error AttributeError: 'ir.ui.view' object has no attribute 'report_action' Thanks in advance 回答1: Make sure that report_action_name is the record_id of the report .

问题 I have a piece of code that converts a unix date to standard U.S. date format. It displays properly in excel, however excel doesn't recognize it as a date. if str(startdate).isdigit(): startdate = int(startdate) date = datetime.datetime.fromtimestamp(int(startdate)).strftime('%m/%d/%Y') ws4.cell(row=cell.row,column=2).value = date ws4.cell(row=cell.row,column=2).number_format = 'MM DD YYYY' Any idea how to get excel to see this as a date rather than text? 回答1: My mistake was assuming the line
