- Sun Jan 22, 2017 12:21 pm #61370 Hi guys!
After reading a few different tutorials on how to post http I'm still failing. Can anyone see anything wrong in my code? (The code is based on a few tutorials, http://bitsofgyan.com/index.php/2016/05/01/http-requests-with-esp8266/ among them.

My code:

Code: Select all#include "ESP8266WiFi.h"
#include "ESP8266HTTPClient.h"
#include <aJSON.h>
 
void setup() {
  Serial.begin(115200);
 
  // Set WiFi to station mode and disconnect from an AP if it was previously connected
  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(100);
  WiFi.begin("XXXXXX", "YYYYYYY");
  Serial.print("Connecting");
  while (WiFi.status() != WL_CONNECTED)
  {
    delay(500);
    Serial.print(".");
  }
  Serial.println();
  Serial.print("Connected, IP address: ");
  Serial.println(WiFi.localIP());
  Serial.println("Setup done");
}
 
void loop() {
  if(WiFi.status()== WL_CONNECTED){   //Check WiFi connection status
    HTTPClient http;
    http.begin("192.168.1.29:8080/");
    aJsonObject *root;
    root=aJson.createObject();
    aJson.addStringToObject(root,"message", "Hello from ESP8266");
    char *payload=aJson.print(root);
    int httpCode = http.POST((uint8_t *)payload,strlen(payload));
    if(httpCode == HTTP_CODE_OK)
    {
      Serial.print("HTTP response code ");
      Serial.println(httpCode);
      String response = http.getString();
    }
    else
    {
      Serial.println("Error in HTTP request");
      Serial.println(httpCode);
    } 
    http.end();  //Close connection
  }
  else{
    Serial.println("Error in WiFi connection");   
  } 
  delay(30000);  //Send a request every 30 seconds
}


The server is a simple webserver written in python

Code: Select allfrom bottle import route, run, request


@route('/', method='POST')
def index():
    postdata = request.body.read()       
    print postdata


run(host='192.168.1.29', port=8080, debug=True)


All I get back is a -1 response, aka something seems wrong on the ESP side.
Also, everything works when i try to post with cURL.

Any ideas?
