php - Restful API for CakePHP 2 -

-

i creating restful webservice cakephp 2 however, getting 500 internal server error since not able capture post data. rest server below:

app::import ( 'vendor', 'exchangefunctions', array ('file'=> 'exchange/exchangefunctions.php'));  class exchangecontroller extends appcontroller {     public $components = array('requesthandler');     public     function index()     {         $exchange = new exchangefunctions();         $data = $this->request->data('json_decode');         $exchange->username = $_post['username'];         $exchange->password = $_post['password'];         $emaillist = $exchange->listemails();         $response  = new stdclass();         $response->emaillist = $emaillist;         foreach($emaillist->messages $listid => $email)         {             $tempemail = $exchange->getemailcontent(                 $email->id,                 $email->changekey,                 true,                 $_post['attachmentpath']             );             $response->emails[$tempemail['attachmentcode']] = $tempemail;         }         $this->set('response', $response);         $this->set('_serialize','response');     } }

and client goes as:

class apitestcontroller extends appcontroller {     public function index()     {         $this->layout = 'ajax';         $jrequesturlprefix = 'http://localhost/ewsapi/';         $posturl           = $jrequesturlprefix."exchange/index.json";          $postdata          = array(             'username'      => 'username',             'password'      => 'password',             'attachmentpath'=> $_server['document_root'] . $this->base . directory_separator . 'emaildownloads' . directory_separator . 'attachments'         );         $postdata = json_encode($postdata);          pr($postdata);         $ch       = curl_init( $posturl );         $options  = array(             curlopt_returntransfer=> true,             curlopt_httpheader         => array(                 'content-type: application/json',                 'content-length: ' . strlen($postdata)             ),             curlopt_customrequest => 'get',             curlopt_postfields     => $postdata,         );         curl_setopt_array( $ch, $options );         $jsonstring = curl_exec($ch);         curl_close($ch);         $data       = json_decode($jsonstring, false);          echo $jsonstring;     }  }

not sure messing up! please help!

ok, after second there more suspicious things. mentioned, curl request uses get instead of post.

$options  = array(     ...     curlopt_customrequest => 'post',     curlopt_postfields     => $postdata, );

another thing encoding post data curl call json, trying access on other side using $_post, there won't anything, post data have key/value query string formatted in order appear in $_post. have read php://input instead, may trying with

$data = $this->request->data('json_decode');

however must use cakerequest::input() purpose, , of course must use $data variable instead of $_post

$data = $this->request->input('json_decode'); $exchange->username = $data['username']; $exchange->password = $data['password'];  ....  $tempemail = $exchange->getemailcontent(     $email->id,     $email->changekey,     true,     $data['attachmentpath'] );

also make double sure curl request looks expected:

$options  = array(     ...     curlopt_postfields => $postdata,     curlinfo_header_out => true // supported of php 5.1.3 ); curl_setopt_array($ch, $options); $result = curl_exec($ch); $info = curl_getinfo($ch); curl_close($ch);  echo '<pre>'; print_r($info); echo '</pre>';

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
