Actually, I wanna have the "Set-Cookie" header responding from the server (I'm using HTTPClient library).
I tried several methods from HTTPClient class (e. g. hasHeader, collectHeaders, headers and header) but I think they only work for request headers.
This is my code:
Code: Select all
#include <WiFi.h>
#include <HTTPClient.h>
const char *ssid = "ssid";
const char *password = "password";
void setup()
{
Serial.begin(115200);
delay(4000);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED)
{ // Check for the connection
delay(1000);
Serial.println("Connecting to WiFi..");
}
Serial.println("Connected to the WiFi network");
if (WiFi.status() == WL_CONNECTED)
{
HTTPClient http;
const char *headerKeys[] = {"Set-Cookie"};
const size_t numberOfHeaders = 1;
http.begin("http://server-url/login"); // Specify destination for HTTP request
http.addHeader("Content-Type", "application/x-www-form-urlencoded"); // Specify content-type header
http.addHeader("User-Agent", "ESP32-IOT-Client"); // Specify User-Agent header
http.addHeader("Connection", "keep-alive"); // Specify connection header
int httpResponseCode = http.POST("username=test&password=test");
http.collectHeaders(headerKeys, numberOfHeaders);
if (httpResponseCode > 0)
{
String response = http.getString();
if (http.hasHeader("Set-Cookie"))
Serial.println("YEAH");
else
Serial.println("NOPE");
for (int i = 0; i < http.headers(); i++)
{
Serial.println(http.header(i));
}
Serial.println(httpResponseCode);
Serial.println(response);
}
else
{
Serial.print("Error on sending POST: ");
Serial.println(httpResponseCode);
}
http.setURL("http://192.168.1.6:8000/");
httpResponseCode = http.GET();
if (httpResponseCode > 0)
{
String response = http.getString();
Serial.println(httpResponseCode);
Serial.println(response);
}
else
{
Serial.print("Error on sending POST: ");
Serial.println(httpResponseCode);
}
}
else
{
Serial.println("Error in WiFi connection");
}
}
void loop()
{
// put your main code here, to run repeatedly:
}
