Error on Http Post
Posted: Sun Jan 22, 2017 12:21 pmHi 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:
The server is a simple webserver written in python
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?

Serial.println(httpCode);
}
http.end(); //Close connection
}
else{

}
delay(30000); //Send a request every 30 seconds
}
The server is a simple webserver written in python
Code: Select all
from 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)
