如果我手動發送第二個請求，它可以正常工作，但是如果我嘗試通過python執行此操作，它將失敗。apache 日志中沒有錯誤。文件保持不變，不會被覆蓋。法典：def fen_actions(mode,fen):    global url    if mode: # 1-> Read 2-> Write        params = {'mode':'readFen'}    else:        params = {'mode':'putFen','fen':fen}    r = requests.get(url,params)    return r.textfen_actions(2,chess.STARTING_BOARD_FEN) #This is not working. Starting fen is just a stringtemp_readed_fen = fen_actions(1,0) # This works代碼：<?php$f = fopen("tempfen.txt","r+") or die("Unable to open a file");if (strval($_GET["mode"]) === strval("putFen")){    if(strval($_GET['fen']) != strval(fread($f,filesize("tempfen.txt"))))    {        file_put_contents("tempfen.txt","");        fwrite($f,$_GET['fen']);    }}else if ($_GET["mode"] === strval("readFen")){    echo(fread($f,filesize("tempfen.txt")));}ini_set('display_errors',1);?>
