如何从 HTTP 客户端向服务器发送数据（字符串）

Question

I've got a simple server, and I need that server to get message from client via http the code of client is

import requests
r = requests.post('http://192.168.0.100:7777',data="Hello")
print(r.text)

My server doesn't catch anything. But I'm quite sure they are connected since the text from the server is being displayed in the console

Server code

int httpCode = http.GET();
if(httpCode>=0){
  String payload = http.getString();
  Serial.println(httpCode);
  Serial.println(payload);
}

Are you sure that it's not a server issue? Try printing r.status_code.

Also, generally you'll want to send the data in a json object.

import json
import requests
data = json.dumps({'message': 'hello'})
request = requests.post('http://192.168.0.100:7777',data=data)
print(request.status_code)
print(request.text)
