私はSOに関するすべての同様の質問を見ました。私はこのエラーを解決しようとしましたが、失敗しました。私はほとんどすべてを試しましたが、解決策は得られません。次のようにエラー：org.json.JSONException：型java.lang.Stringの値<brはJSONObjectに変換できません
私のコードは次のとおりです。 -

これは私のPHPファイルである
<?php
$response = array();
if (isset($_POST['name']) && isset($_POST['email']) && isset ($_POST['password']))
{
$name = $_POST['name'];
$email = $_POST['email'];
$password = $_POST['password'];
require_once __DIR__ . '/db_connection.php';
$db = new DB_CONNECT();
$result = mysql_query("Insert into words(name,email,password) values('$name','$email','$password')");
if ($result)
{
$response["success"] = 1;
$response["message"] = "Registration successfully.";
echo json_encode($response);
}
else
{
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
echo json_encode($response);
}
}
else
{
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
echo json_encode($response);
}
?>
私のJSON応答は次のとおりです。 -
{"success":0,"message":"Required field(s) is missing"}
エラーを識別することができます教えてください私。
