jquery - Modify HTTP Headers for a JSONP request -

-

I am using jquery to create a request for Twitter Search API. I am using jsonp, as is necessary for cross-domain requests, however, the Twitter API specifies that you should set up a unique user-agent for these requests, and if you do not limit your requests Do it. The problem is, I do not see any way to set this header through jquery.

This is the code I am using: 

  $ Ajax ({url: 'http: //search.twitter.com/search.json', datatype: 'jesnp', type: 'received', data: {q: 'twitter'}, success: work {data} Warning (data results);}});

I have tried to use the first method method, but it appears that this event is not firing. Can anybody come in any way to solve this problem?

Thank you.

works by adding a script element to the JSON page with padding, src Attribute the URL of the web service along with the attribute. The web service then returns a script that contains data wrapped in a callback function, when the script is full parsing. This is not so much JSON (this is not a valid JSON for a beginner) because it is a plain JavaScript.

There is no way to modify the header sent for a script element, which is unfortunately the only thing you can do is check the cross-basic consistent method of getting the data Like:

  • - Chrome, Safari 4+, Firefox 3.5+, Opera 

      // Is XMLHttpRequest level 2 supported? If (with "credentials" in the new XMLHttpRequest)

  • - For IE 8, IE 9 

      // XDomainRequest is supported? If in these windows "XDomainRequest" (in the "XDomainRequest" window)

It would be a good idea to test for these conditions if they exist And use them accordingly, standard unsupported or JSONP for older browsers

This is also possible (but it is unlikely that this is a high profile), that the web service should allow cross-root requests Is not set up, so if the request fails You may still have to come back to JSONP. See also.

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).
