http.getString returns empty string since update
Posted: Mon Jul 27, 2020 7:43 amI have a very simple sketch that worked fine with ESP8266 board version 2.7.1 - but with 2.7.2 it just returns an empty string
This happened on a NodeMCU ESP-12E with the latest Adruino IDE (1.8.13 - Windows 10 Install (not the store version - if this is important) - since this is the only type I have right now, I cannot check it on different hardware. I tried two PCs - same result.
once I roll back to 2.7.1 it works - back to 2.7.2: empty string.
Am I doing something wrong or is this a bug in the latest release?
Code: Select all
#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>
const char* ssid = "mynet";
const char* password = "mypwd";
void setup () {
Serial.begin(115200);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.print("Connecting..");
}
}
void loop() {
Serial.println("Connected..");
if (WiFi.status() == WL_CONNECTED) { //Check WiFi connection status
HTTPClient http; //Declare an object of class HTTPClient
http.begin("http://192.168.10.101/temp"); //Specify request destination
int httpCode = http.GET(); //Send the request
Serial.print("htcode: ");
Serial.println(httpCode);
if (httpCode > 0) { //Check the returning code
String payload = http.getString(); //Get the request response payload
Serial.print("###");
Serial.print(payload); //Print the response payload
Serial.println("###");
}
http.end(); //Close connection
}
delay(30000); //Send a request every 30 seconds
