web services - Write full HTTP POST request packet -


i need write full http request invoke soap service. don't have libraries soap request need write full http packet. how i've proceeded (i'm programming arduino board):

string body = httprequestbody("33", "77%");  client.println("post /dataserver http/1.1"); client.println("accept: text/xml, multipart/related"); client.println("content-type: text/xml; charset=utf-8"); client.println("soapaction: \"http://example.com/functions/senddatarequest\""); client.println("user-agent: arduino wifishield"); client.println("content-length: "+body.length()); client.println("host: arduino-data-server.appspot.com/dataserver"); client.println("connection: keep-alive"); client.println(); client.println(body);

client represent connection webservice. httprequestbody function:

string httprequestbody(string v1, string v2) { serial.println("generating xml message..."); string res = ""; res += "<?xml version=\"1.0\"?>\n\r"; res +="<s:envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\"\n\r"; res +="<s:body>\n\r"; res +="<ns2:senddata xmlsn:ns2=\"http://example.com\">\n\r"; res +="<arg0>"+v1+"</arg0>\n\r"; res +="<arg1>"+v2+"</arg1>\n\r"; res +="</ns2:senddata>\n\r"; res +="</s:body>\n\r"; res +="</s:envelope>\n\r"; serial.println(res);  return  res; }

but gone wrong , can't contact webserver. webserver works , it's reacable, because if change post get, on webservice log, see connection. how can fix it?

in httprequestbody allocating: string res = ""; , updating it. finally, return res. but, res allocated on stack of httprequestbody (??), not guaranteed there after httprequestbody terminates.

you need c++ equivalent of malloc used in c code, in order ensure res on heap , not freed.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
