PHP creates a simple restful WebAPI (iii)

The previous article recorded how to implement the route, this document how to achieve request,response.

　　Request Processing Requests

<?PHPclassrequest{Private $request _vars; Private $data; Private $http _accept; Private $method; Private $ID;  Public function__construct ($id=NULL)      {          $this->request_vars =Array(); $this->data =Array(); $this->http_accept = ' Application/json '; $this->method = ' Get '; $this->id =$id; $this-ProcessRequest (); }       Public functionProcessRequest () {$request _method=Strtolower($_server[' Request_method ']); $this->setmethod ($request _method); $request _vars=$_get; if($request _vars! = "){            $this->setrequestvars ($request _vars); }          $data=file_get_contents(' Php://input '); if($data! = "){            $this->setdata (Json_decode ($data,TRUE)); }     }      Public functionSetID ($id)      {          $this->id =$id; }         Public functionSetData ($data)      {          $this->data =$data; }         Public functionSetmethod ($method)      {          $this->method =$method; }         Public functionSetrequestvars ($request _vars)      {          $this->request_vars =$request _vars; }     Public functionGetID () {return $this-ID; }         Public functionGetData () {return $this-data; }         Public functionGetMethod () {return $this-method; }         Public functiongethttpaccept () {return $this-http_accept; }         Public functionGetrequestvars () {$this->request_vars[' id '] =$this-ID; return $this-Request_vars; }  }  ?>

The code is simple, which is to get the request method,querystring from request, requesting the body data (in JSON format).

　　Response Send Response

<?PHPclassresponse{ Public function__construct () {} Public functionSendresponse ($status= 200,$body= ",$content _type= ' Application/json ')     {         $status _header= ' http/1.1 '.$status. ‘ ‘ .$this->getstatuscodemessage ($status); Header($status _header); Header(' Content-type: '.$content _type. ‘; Charset=utf-8 '); Echo $body; Exit; }     Public functionGetstatuscodemessage ($status)      {          $codes=Array ( ' Continue ', 101 = ' Switching Protocols ', ' OK ', 201 = ' C  Reated ', 202 = ' Accepted ', 203 = ' non-authoritative information ', 204 = ' No content ', 205 = ' Reset content ', 206 = ' Partial content ', + = ' M Ultiple Choices ', 301 = ' Moved permanently ', 302 = ' Found ', 303 = ' See              Other ', 304 = ' not Modified ', 305 = ' Use Proxy ', 306 = ' (Unused) ',              307 = ' Temporary Redirect ', and ' bad Request ', 401 = ' Unauthorized ',              402 = ' Payment Required ', 403 = ' Forbidden ', 404 = ' not Found ', 405 = ' Method not allowed ', 406 = ' not acceptable ', 407 = ' Proxy authentication Re Quired ', 408 = ' Request Timeout ', 409 = ' Conflict ', 410 = ' Gone ', 411 = ' Lengt              H Required ', 412 = ' precondition Failed ', 413 = ' Request Entity Too Large ', 414 = ' Request-uri Too Long ', 415 = ' Unsupported Media Type ', 416 = ' Requested Rang              E not satisfiable ', 417 = ' expectation Failed ', and ' Internal Server Error ',              501 = ' Not implemented ', 502 = ' bad Gateway ', 503 = ' Service unavailable ', 504 = ' Gateway Timeout ', 505 = ' HTTP Version not supported '          ); return(isset($codes[$status])) ?$codes[$status] : ‘‘; }}  ?>

Generate response.

These two classes are tool classes, implementation is not complex, functional single, need to continue to enrich the changes.
