HTTPSRedirect String Comparison does not match

Projects Programming
3

Code works properly, except when I try to compare the incoming string (labeled 'str') to a string that I have declared in my code (labeled 'purchase').

A String is NOT a string.

   String str = client->getResponseBody();
 Serial.print("Who's beer is this?:':");
 Serial.print(str);
//Refresh the LCD before displaying the most current cell contents   
  lcd.clear(); 
 //The following was written by Goet:https://forum.arduino.cc/index.php?topic=216486.0 to center the contects on the LCD screen
  int pinnedRow = 0; // LCDHEIGHT / 2;
  String pinnedText = str;
  int l = pinnedText.length();
  lcd.setCursor(l % 2 == 0 ? LCDWIDTH / 2 - (l / 2) : LCDWIDTH / 2 - (l / 2) - 1, pinnedRow);
 pinnedText= pinnedText.substring(0, pinnedText.length() - 2);
 lcd.print (pinnedText);

//Read Data from cell D1, if it matched the string "Beer Purchased", then open the solenoid for x seconds (or turn off back light for testing purposes)
 
if (client->GET(url3, host)){
   ++connect_count;
 //assign the outpult string ofthe readD3 Google appps function to a string called 'flag'
   String str= client->getResponseBody();
   Serial.print("Output from Google Sheet: ");
   Serial.print(str);
   
  }
      else{
    ++error_count;
    DPRINT("Error-count while connecting: ");
    Serial.print("First Error while connecting");
    DPRINTLN(error_count);
  }
  
String purchase = "Beer Purchased";
Serial.print("Output from 'purchase' string: ");
Serial.print(purchase);

if(str == purchase){

Which str do you think you are comparing to purchase? Dollars to donuts it is NOT the one you think is being compared.
