Question

我的问题是关于以下脚本的：

我在StackOverflow上看到了这个问题ByetHost server passing html values "Checking your browser" with JSON String，但我不知道如何更改我的java。请帮我。我使用免费的vistapanel。

php

<?php

 if($_SERVER['REQUEST_METHOD']=='POST'){
 
 $image = $_POST['image'];
 
 require_once('UploadToServer.php');
 
 $sql = "INSERT INTO images  VALUES (?)";
 
 $stmt = mysqli_prepare($con,$sql);
 
 mysqli_stmt_bind_param($stmt,"s",$image);
 mysqli_stmt_execute($stmt);
 
 $check = mysqli_stmt_affected_rows($stmt);
 
 if($check == 1){
 echo "Image Uploaded Successfully";

 }else{
 echo "Error Uploading Image";

 }
 mysqli_close($con);
	
 }else{
 echo "Error";

 }
 exit();
 ?>
