Ethernetclient not sending all data ?

Hey

I seem to have a issue with my ethernetclient, I am trying to post data to my webserver but the piece of code I use seems to only work when in setup, and not in my loop.

It concerns this snippet:

//connection to API server
      if(toAPI.connect(API_IP, 80)>0)
	{
        toAPI.println( "POST /SensorData/ HTTP/1.1" );
        toAPI.println( "Host: 10.10.4.165" );
        toAPI.println( "Content-Type: application/json; charset=UTF-8" );
        toAPI.println( "Connection: keep-alive" );
        toAPI.print( "Content-Length: " );
        toAPI.println( 58 );  //data.length()
        toAPI.println("Cache-Control: max-age=0");
        toAPI.println("Accept-Language: en-US,en;q=0.8");
        toAPI.println();
        toAPI.print( "{\"user_id\" : 1, \"temperature\" :  222.2 , \"heartrate\" : 222}" );  //data
        toAPI.println();
      
         while(toAPI.available()) 
         {
          char c = toAPI.read();
          Serial.print(c);
        }
      }
      else
      {
        Serial.print("NCON");
      }
        
        toAPI.stop();  
        
      
    }

If I check my Apache error.log, I get the following errors:

 [error] [client 10.10.4.170] PHP Notice:  Undefined index: PATH_INFO in /var/www/index.php on line 49
[Wed Nov 28 18:38:17 2012] [error] [client 10.10.4.170] PHP Notice:  Undefined offset: 1 in /var/www/index.php on line 28

(I am checking for $this->url_elements = explode('/', $_SERVER['PATH_INFO']); )

This is what's in my Apache access.log

10.10.4.170 - - [28/Nov/2012:18:38:17 +0100] "POST /SensorData/ HTTP/1.1" 200 574 "-" "-"
10.10.4.170 - - [28/Nov/2012:18:38:17 +0100] "}" 200 131 "-" "-"

I have no idea where the curly bracket comes from, I tried changing the connection: keep-alive to close. Doesn't help.
the toAPI.read() doesn't seem to return anything either.

Does anyone know why the ethernetclient could fail ? the .connect() returns true, and I am seeing a 200 status in my apache. Yet, the PHP script fails.

Just a little addon, if I use this code

 while(toAPI.connected()) {
       // the server will close the connection when it is finished sending packets
       while(toAPI.available()) {
          
          Serial.print(toAPI.read());
           }
        }

The toAPI.read returns things like

Hey Guys/Girls

The issue has been resolved, it was as simple as having a extra space I didn't see in my body, and therefore the content length was incorrect.

Hello and welcome,

Good that you solved it yourself :slight_smile:
