Php 从android手机向mysql数据库插入数据

想知道有人能帮我吗我对安卓系统还很陌生，我在尝试创建的一个应用程序中遇到了一个问题。该应用程序从附近的手机接收rssi值，然后我尝试将这些读取数据保存到web服务器，根据Logcat，我看起来连接正常，但我在PHP脚本中的SQL查询似乎导致了问题，我可能错了。如果有任何帮助，将不胜感激

我正在发布我的android代码、php脚本和logcat

            String rssi1 = params[1];

            String rssi2 = params[3];

            // Add items to be added to the database

            JSONObject json_data = new JSONObject(result);

            int code = (json_data.getInt("code"));

            if (code == 1)
            {
                Toast.makeText(getBaseContext(), "Inserted Successfully", Toast.LENGTH_SHORT).show();
            }

        {

        }

        return "complete";
    }

    protected void onPostExecute(String string)

无效的
07-08 23:35:52.406 5465-5500/com.lyit_android_society.com.rssireader E/Fail 3﹕ org.json.JSONException:Value您需要修复sql字符串。它们在值周围缺少单引号。
即应为：

mysql_查询（$con，“插入电话_表（ap，rssi）值（$ap1'，$rssi1'））

但我还必须补充一点，您应该修复代码以防止sql注入。这不是与数据库交互的最佳方式。看看像标准PDO（）这样的MySQL API。一般来说，sql应该参数化，传递给数据库的所有值都应该转义。大多数API都提供了一些方便的方法来帮助实现这一点。
强制性建议。它们不再得到维护。看到了吗？相反，学习，并使用，或-将帮助您决定哪一个。如果您选择PDO


我已将您的代码移植到PDO，希望能有所帮助

根据您的服务器，您可能无法远程建立该连接。您可能应该尝试使用we view并以这种方式发送数据，因为它将从服务器上运行。您在哪里设置
$host、$username、$password、$dbname
？以及它的
mysql\u查询（'SQL'，$con）您的应用程序也可能被滥用，请在启用之前修复SQL注入漏洞，另外，
mysql.*
函数也不推荐使用。RTM
mysql.\u query（string$query[，resource$link\u identifier=NULL]）
阅读我关于$conThank的评论谢谢你的帮助我只是想了解一下这其中的大部分内容，所以这是一个很棒的.np，我想我只是移植它，而不是告诉你做错了，并给出一个使用旧API的答案。。你可能不理解。另外，我更喜欢写代码，而不是随意的长句子。快乐编码！
