我确定这只是一个小问题，但我无法弄清楚我需要改变什么：我的应用程序中有一个注册页面。当用户插入数据时，数据将传递给php脚本并存储在MYSQL数据库中。连接工作正常，因为我在数据库中获得了一个新用户，但是json $ success不起作用 - 如果用户可以注册，我想制作一个Toast并更改为一个新活动，但是当我点击它时它什么都不做按钮。
这是我的Java代码：

这是php文件：

session_start();
$name = $_POST["enteredname"];
$pass = $_POST["enteredpassword"];
$pass2 = $_POST["enteredpassword2"];
$email = $_POST["enteredemail"];
$tel = $_POST["enteredTelnr"];
$geb = $_POST["enteredGeb"];
$gender = $_POST["userGender"];
if($pass != $pass2) {
$success = 0;
}
else {
$hash = md5($pass);
$speichern = "INSERT INTO user (user_name, user_pw, user_mail, user_tel, user_geb, user_geschl)
VALUES('$name', '$hash', '$email', '$tel', '$geb', '$gender');";
mysql_query($speichern) or die(mysql_error());
if($speichern) {
$success = 1;
}
}
echo json_encode($success);
?>
提前致谢！

问题是您没有为要返回的内容类型返回HTTP标头。
将其添加到php脚本的顶部：
header("Content-Type: application/json;charset=utf-8");
答案 1 :(得分：0)
所以我认为我发现了错误，在日志中它表示jsonresult无法转换，这是因为在PHP脚本中我写了$ success = 0;但我认为它必须像$ response [“success”] = 0;
