Php 将数据添加到本地主机上的Mysql数据库

我正在尝试创建注册表，但应用程序一直崩溃 我想这可能是我的虚拟仿真器的URL，我尝试了10.0.2.2和10.0.3.2，我选中了虚拟框以查看要使用的地址，我得到了192.168.79.2，但它们都不起作用

这是我的BackgroundTask.java类

这是我的register.php文件

你的解决方案 从我所看到的，第一行应该是urlcoder.encodeuser，UTF-8吗？显然，您的PHP表单显示$names=$\u POST[names]；，这意味着POST变量应该是names

如果数据库未配置空变量，则会出错

String data = URLEncoder.encode("user", "UTF-8")+"="+URLEncoder.encode(names, "UTF-8")+"&"+
              URLEncoder.encode("user_name", "UTF-8")+"="+URLEncoder.encode(user_name, "UTF-8")+"&"+
              URLEncoder.encode("user_pass", "UTF-8")+"="+URLEncoder.encode(user_pass, "UTF-8");

将异步任务调用为

ArrayList<String> params = new ArrayList<String>();
                        params.add(name);
                        params.add(userId);
                        params.add(passw);
                        new registerTask().execute(params);

试试这个：

 public class registerTask extends AsyncTask<ArrayList<String>, Void, ArrayList<String>> {

            @Override
            protected void onPreExecute() {
                progress1.setVisibility(View.VISIBLE);
            }

            protected ArrayList<String> doInBackground(ArrayList<String>... passing) {
                ArrayList<String> result = new ArrayList<String>();
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost("http://192.168.79.2/webapp/register.php");
                String responses = null;
                ArrayList<String> data = passing[0];
                String name = data.get(0);
                String uid = data.get(1);
                String passw = data.get(2);
                int ik;
                try {
                    //add data
                    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
                    nameValuePairs.add(new BasicNameValuePair("names", name));
                    nameValuePairs.add(new BasicNameValuePair("user_name", uid));
                    nameValuePairs.add(new BasicNameValuePair("user_pass", passw));
                    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                    //execute http post
                    HttpResponse response = httpclient.execute(httppost);
//You will get the response from server in response
                    HttpEntity entity = response.getEntity();
                    String content = EntityUtils.toString(entity);
                } catch (ClientProtocolException e) {
                } catch (IOException e) {
                }
                return "Success"; //return result
            }

            protected void onPostExecute(ArrayList<String> result) {
            }
        }

我不知道我是否错过了什么。。。。

试试这个。

谢谢@lefsFlare我的导入有问题

我改为：javax.net.ssl.HttpsURLConnection；

---

收件人：java.net.HttpURLConnection

你的港口是什么？例如，我有57714是我的端口，在你的模拟器中检查应用程序。我如何找到这个端口？以前从未试过！试试这个：让我知道它对你有用吗？10.0.3.2成功了我的导入中有一个问题。谢谢你，我修复了它，但它还是崩溃了。我运行了调试器，它在这一行httpsURLConnection.setRequestMethodPOST崩溃了@OdeyM.Khalaf调试器怎么说？@OdeyM.Khalaf这很奇怪，你能把堆栈跟踪粘贴到帖子的末尾吗？我想这是错的，我给了你错误的消息：由以下原因引起：java.lang.ClassCastException:com.android.okhttp.internal.huc.HttpURLConnectionImpl不能转换为javax.net.ssl.HttpsURLConnectionOk，你能贴上进口商品吗？我想你可能进口错了包装，但我不确定。
