JSONException PHP Android

你能帮我吗？ 所以我想从远程数据库获取数据。 我已经下载并安装了WAMP服务器并连接到远程数据库，我已经添加了一些行ecc。。。 使用PHPStorm，我创建了一个看起来很有效的脚本，它显示了我所需要的一切。 问题是logcat，你能告诉我如何修复它吗

这里是我的PHP脚本

---

首先，你不应该发布你的IP。说到您的问题，您收到了一个无法转换为JSON的HTML页面。这可能是一个错误或其他任何情况，在尝试将其转换为JSON之前，请尝试打印收到的响应，您可能会知道发生了什么情况
php生成的JSON文件中有一个错误。特定的安卓认为您提供的pdf链接不是JSONArray，可能是json对象？建议您测试json并在此处发布整个json响应
 
您没有访问/config.php的权限
检查您的服务器配置或粘贴您的服务器配置现在问题是其他的……我有另一种类型的问题为什么您在php中返回HTML？如果需要JSON，请在while循环中创建一个数组填充它，给元素一个名称和值，并在循环后对其进行JSON编码。如果您不想在客户端将HTML解码为JSON，您可以在JSON值中创建一个HTML格式字符串，但需要给它一个键名，然后将数组编码为JSON
