architecture - Handling Error Messages -

-

Recently, I wanted to separate communication between client and server in a rich web application, which is made up of most widgets. Was there. Responses to the client are in a JSON format when the error message was time to make decisions about arranging two cases.

  1. Send feedback error parts such as

    {"success": "false", "errors": ["field 1": "message 1 "," Field 2 ":" Message2 "]}

  2. Send errors as headers and just return false to react ('X-application-error ',' ["Field 1": "message1", "field2": "message2"] ')

/ P>

The second option is clearly visible; The user only checks the errors in the header, when they want, the errors seem to be in this way to become part of the protocol instead of being part of the reaction.

Is this a good practice? One way is better than the other.

I will send an error message as part of the response.

Adding custom headers is what you want to report things at the HTTP protocol level; HTTP has established methods of reporting errors (via HTTP status code) I will leave the thing which will be shown to the customer in the body of the response (or used by Javascript).

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
