Need Help With My Project
1

At ESP8266 12E is blynk and is controlled through the app with Android device, but with the help Below code is not managed. What am I doing wrong? below shows examples of a response from the server and the code itself.

package ru.shapovalov.http_responce;

import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.MediaType;

public class Responce {
public Responce() {
}

public static void main(String[]args){
send();
}

protected static void send(){

Client client = ClientBuilder.newClient();
Entity payload = Entity.json("[“1”]");
Response response = client.target(“http://blynk-qa.cloudapp.net/My_token/pin/d12”)
.request(MediaType.APPLICATION_JSON_TYPE)
.put(payload);

System.out.println("status: " + response.getStatus());
System.out.println("headers: " + response.getHeaders());
System.out.println(“body:” + response.readEntity(String.class));
}
}

If sending “[” 1 \ “]” I get:
status: 200
headers: {Connection=[keep-alive]}

If sending “[]” I get: status: 400
headers: {Connection=[keep-alive], Content-Length=[27], Content-Type=[text/plain]}
body:No pin for update provided.

If sending “[‘1’]” I get: status: 500
headers: {Connection=[keep-alive], Content-Length=[31], Content-Type=[text/plain]}
body:Error parsing body param. [‘1’]

Вот написал не большой кусочик кода может кому пригодится)

package ru.shapovalov.http_responce;

import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

public class Responce {
public Responce() {
}

public static void main(String[]args){
    String url = "http://cloud.blynk.cc:8080/<my_token>/pin/d4";

System.out.println(turn(url));

}
protected static boolean turn(String url){
Client client = ClientBuilder.newClient();
if (read(url, client)) {
send(0, url, client);
// System.out.println(0);
} else {
send(1, url, client);
// System.out.println(1);
}
return read(url, client);
}

protected static void  send(int value, String url, Client client){

    Entity payload = Entity.json("[\""+ value +"\"]");
    client.target(url)
            .request(MediaType.APPLICATION_JSON_TYPE)
            .put(payload);
}
protected static boolean read(String url, Client client){
  Response  response = client.target(url)
            .request(MediaType.TEXT_PLAIN_TYPE)
            .get();
    String read = response.readEntity(String.class);

// System.out.println(“pin status:” + read);
if(read.equals("[“1”]")){
return true;
}else {
return false;
}
}
}
