尽管将内容类型设置为“application/json”，但PHP还是添加了其他文本以响应
尽管添加了代码，但返回响应的内容类型为application/json。我只想要JSON数据，但是不管我调试PHP时发生了什么变化，都会添加额外的垃圾数据，我可以看到Route.php正在添加$output，它有这些额外的数据
$app->POST('/api/user/new', function ($Request, $response) { $json = file\_get\_contents('php://input'); $obj = new users(); $obj = json\_decode($json); // {"id":"1","typeId":"1","name":"Haridev Nirgude","phone":"8121155693", // "email":"haridevnirgude@gmail.com","deptID":null,"password":"Hyderabad143","insession":"0"} $typeId= $obj->typeId; $name= $obj->name; $phone=$obj->phone; $email=$obj->email; $deptID=$obj->deptID; $password=$obj->password; $userID = $obj->userID; $sql = "INSERT INTO users (typeId,name,phone,email,deptID,password,userID) VALUES (:typeId,:name,:phone,:email,:deptID,:password,:userID)"; try{ // Get DB Object $db = new db(); // Connect $db = $db->connect(); $stmt = $db->prepare($sql); //$stmt->bindParam(':',$); $stmt->bindParam(':typeId',$typeId); $stmt->bindParam(':name',$name); $stmt->bindParam(':phone',$phone); $stmt->bindParam(':email',$email); $stmt->bindParam(':deptID',$deptID); $stmt->bindParam(':password',$password); $stmt->bindParam(':userID', $userID); $stmt->execute(); $result = '{"type":"success","text": "User Registered successfully"}'; return $response->withStatus(200)->withHeader('Content-Type', 'application/json')->write($result); //echo '{"type":"success","text": "User Added successfully"}'; // echo '{"notice": {"text": "User Added successfully"}'; } catch(PDOException $e){ $result = '{"type":"error","text":'.$e->getMessage().'}'; return $response->withStatus(200)->withHeader('Content-Type', 'application/json')->write($result); }});'
我的错误越来越少。我有各种方法，比如withJson，也使用了请求，接口的响应仍然在下面的文本中添加了JSON响应数据

当我使用XDebug调试PHP时，由于错误，它正在编写额外的内容。
我可以禁用XDebug和PHP错误报告，并在代码中处理异常。
在PHP文件中添加了下面的代码。
error_reporting(0);// disable the error from PHP
if (function_exists('xdebug_disable')) {
xdebug_disable(); //disable xdebug error
}此外，该问题与作为null发送的字段之一有关。请求中的deptID字段，这将导致在响应中添加垃圾数据。
我已经纠正了这一点，并且总是试图从客户端传递该deptID的空白值，或者我可以在服务器端处理它，但是这会造成复杂的情况。
