why is mimetypes.guess_type('a.json') not working in centos 7

故事扮演 提交于 2019-12-12 17:30:18
问题 In Centos, why is python 2.7 prebuilt library mimetypes.guess_type not returning mimetype for json files? https://docs.python.org/2/library/mimetypes.html# I am using guess_type in mimetypes and it returns different value in centos/ubuntu. What's the pythonic way to deduce mimetype from filename in different OS? In ubuntu 14.04, it returns the correct mime type >>> import mimetypes >>> mimetypes.guess_type('a.json') ('application/json', None) But in Centos7 >>> import mimetypes >>> mimetypes

Expressing byte values > 127 in .Net Strings

旧街凉风 提交于 2019-12-12 17:30:13
问题 I'm writing some binary protocol messages in .Net using strings, and it mostly works, except for one particular case. The message I'm trying to send is: String cmdPacket = "\xFD\x0B\x16MBEPEXE1."; myDevice.Write(Encoding.ASCII.GetBytes(cmdPacket)); (to help decode, those bytes are 253, 11, 22, then the ASCII chars: "MBEPEXE1." ). Except when I do the Encoding.ASCII.GetBytes , the 0xFD comes out as byte 0x3F (value 253 changed to 63). (I should point out that the \x0B and \x16 are interpreted

Maximum Size of patch to customSchemas?

大憨熊 提交于 2019-12-12 17:30:12
问题 I'm having an issue with the SDK. I followed this guide to get SSO with AWS. I'm able to add 4 roles using my code, but after that I get a 413.

So, each patch I make requires me to resubmit the entire role array according to the docs: Note about arrays: Patch requests that contain arrays replace the existing array with the one you provide. You cannot modify, add, or delete items in an array in a piecemeal fashion. Python Snippet:

Disabling button after disable_with

天涯浪子 提交于 2019-12-12 17:30:10
问题 In my Rails app, I use the :disable_with helper on a form button. That form works via ajax. If the object is created successfully, I want to keep that button disabled. So in my create.js.erb file I have: $('#my-button').disabled = true; . However, it doesn't work (works fine in the console though). I suspect its interfering with Rails' JS for the disable_with helper. How can I get around that? 回答1: Use jQuery's .prop() method to set the disabled property of the button. In your case, the code
