arduino yun connect to jsp
0
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);
}
a.jsp
<%@ page language="java" contentType="text/html;
charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01

</body>
</html>
I don't live in English.
So I ask you to understand if English is strange.
I unconditionally want to receive data via the post method via jsp.

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
