php - ESP8266 send GET request to remote server -

http://www.universalcard.byethost7.com server. kept index.php file. code given below

<?php if(isset($_get['username']) && isset($_get['pin']) && isset($_get['cost'])) {  $username = $_get['username']; $pin = $_get['pin']; $cost = $_get['cost']; $filecontent = "username is: ".$username." , pin is: ".$pin." , cost is: ".$cost."\n"; $filestatus = file_put_contents('uc.txt',$filecontent,file_append); if($filestatus != false ) {     echo "data written file.."; }else{     echo "ohh sorry.."; }  } else {      echo "something went wrong.."; } ?> 

and want send request esp8266 arduino ide. in request, sending 3 variables 'username' , 'pin' , 'cost' values (data type string). , these values appending file "uc.txt". when send request using browser, values append text file.

but when tried send using esp8266 not appending

arduino code below

#include <esp8266wifi.h> #include <wificlientsecure.h>  const char* ssid = "rainbow"; const char* password = "12345678";  const char* host = "universalcard.byethost7.com"; const int httpsport = 443;  // use web browser view , copy // sha1 fingerprint of certificate //const char* fingerprint = "cf 05 98 89 ca ff 8e d8 5e 5c e0 c2 e4 f7 e6 c3 c7 50 dd 5c";  void setup() {   serial.begin(115200);   serial.println();   serial.print("connecting ");   serial.println(ssid);   wifi.begin(ssid, password);   while (wifi.status() != wl_connected) {     delay(500);     serial.print(".");   }   serial.println("");   serial.println("wifi connected");   serial.println("ip address: ");   serial.println(wifi.localip());    // use wificlientsecure class create tls connection   wificlientsecure client;   serial.print("connecting ");   serial.println(host);   if (!client.connect(host, httpsport)) {     serial.println("connection failed");     return;   }    string url = "/index.php?username=2bv14is114&pin=5555&cost=1111";   serial.print("requesting url: ");   serial.println(url);    client.print(string("get ") + url + " http/1.1\r\n" +                "host: " + host + "\r\n" +                "user-agent: buildfailuredetectoresp8266\r\n" +                "connection: close\r\n\r\n");    serial.println("request sent");   while (client.connected()) {     string line = client.readstringuntil('\n');     if (line == "\r") {       serial.println("headers received");       break;     }   }   string line = client.readstringuntil('\n');   if (line.startswith("{\"state\":\"success\"")) {     serial.println("esp8266/arduino ci successfull!");   } else {     serial.println("esp8266/arduino ci has failed");   }   serial.println("reply was:");   serial.println("==========");   serial.println(line);   serial.println("==========");   serial.println("closing connection"); }  void loop() { } 

and output in serial monitor below

your host has sort of protection (maybe against bots), expects _test cookie set javascript, if not present.

you acquire cookie, first visiting site browser , copy paste cookie code.
need same ip, esp8266 introduced server, since cookie ip bound.
in case have problem, if have dynamic ip , longevity of cookie unknown.

you acquire cookie parsing response, cookie aes encrypted , complicated.

the sensible solution switch host without such protection.
solution same problem in this , this question.
