I use arduino yun. I want to integrate yun and jsp. However, I am having trouble passing data through curl. What I would like to do is send a String a = "a" to http: // localhost: 8181 / arduino / a.jsp via the post method

#include <Bridge.h>

#include <HttpClient.h>





void setup() {

    pinMode(13, OUTPUT);

    digitalWrite(13, LOW);

    Bridge.begin();

    digitalWrite(13, HIGH);



    Serial.begin(9600);

    while (!Serial); 

}



void loop() {

    String var = "";

    var = "a=a";

    Serial.println(var);



    HttpClient client;



    if (client.connect("192.168.43.38",8181))

    {                                 

        Serial.println("Sending to Server: ");                    

        client.println("POST /arduino/a.jsp 

      HTTP/1.1");           

       client.println("Host: 192.168.43.38");

       client.println("Content-Type: application/x- 

      www-form-urlencoded");

       client.println("Connection: close");

       client.println("User-Agent: Arduino/1.0");

       client.print("Content-Length: ");

       client.println(var.length());

       client.println();

       client.print(var);

       client.println();                                           

     }





    if (client.read() == 1) {

        Serial.println("OK");

    } else {

        Serial.println("Error");

    }



        Serial.flush();

        delay(1000);

 }

So I ask you to understand if English is strange.

The JSP code looks okay. If a parameter 'a' is included in the request it should be output. I do not see that you send a parameter 'a' however. I don't anything about YUN or posting data from it but a simple GET (arather than POST) request should work i.e. GET /arduino/a.jsp?a=passedValue
