javascript - Sending data from an HTTPS page to a localhost server -

-

i wondering best way send data https webpage loaded in browser server running on localhost be. have solution works both http , https pages, https pages browser output mixed content warning (as should). can bypassed changing browser settings, i'd rather not have users that. javascript loaded in browser through bookmark (not sure if best way it, browser independent): 

    function sendlocalpost(player, song) {     var url = "http://localhost:13337/";      $.ajax({         type: "post",         crossdomain: true,         contenttype: "application/json; charset=utf-8",         url: url,         datatype: "json",         data: { 'player': player, 'song': song },         success: function (data) {         }     }); }

and here important snippets c# server code:

    public webapphandler()     {         // other non-important stuff         listener = new httplistener();         listener.prefixes.add("http://localhost:13337/");     }      public void pollforsongchanges()     {         try         {             listener.start();         }         catch (httplistenerexception)         {             return;         }         while (listener.islistening)         {             var context = listener.getcontext();             processrequest(context);         }         listener.close();     }      public void start()     {         pr = new thread(new threadstart(pollforsongchanges));         pr.start();     }

there's question saw on stackoverflow has great answer (the accepted one), requires bind ssl certificate application, mean have actual trusted ssl certificate localhost server in order have work out-of-the-box on other computers?

maybe i'm going wrong, wondering if there better way. answers.

@alexeilevenkov, mean this: 

    function posttoiframe(data) {         var url = "http://localhost:13337/";         var target = "npiframe";          $('body').append('<form action="' + url + '" method="post" target="' + target + '" id="posttoiframe"></form>');         $.each(data, function (n, v) {             $('#posttoiframe').append('<input type="hidden" name="' + n + '" value="' + v + '" />');         });         $('#posttoiframe').submit().remove();     }

basically, can't this. because hacking.

but, if can modifiy client's hosts file, route localhost 'yourdomain.com' , generate ssl certificate 'yourdomain.com'.

or can make proxy server(https://targetdomain.com http://localhost) in localhost server.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
