将注册数据从Android上传到PHP服务器

Question

我的PHP代码如下

         <?php
         error_reporting(~E_NOTICE);
         //include('db.php');

        if($_GET['fname'])
           {
           $fname=$_GET['fname'];
           //echo $fname.'gytgy';
                 }
           if($_GET['lname'])
            {
          $lname=$_GET['lname'];
             //echo $lname.'vbvcbcvb';
            }
           if($_GET['email'])
          {
            $email=$_GET['email'];
           //echo $email.'fgfdgdf';
              }
          $conn=mysql_connect("localhost","MyserverDatabase username","MyserverDatabase password");
         if(!$conn)
              {
                die("could not connect". mysql_error());
                  }
             mysql_select_db("MyserverDatabase username",$conn);


          //$name =$_POST['name'];
         $query="insert into android
           (fname,lname,email)values('".$fname."','".$lname."','".$email."')";

          $query1=mysql_query($query);
            if ($query1="")
         {echo "unsuccessfull";
              }
              else
            {
         echo"successfull";
            }
               ?>

我的Android Java代码如下

      public class AUSRWC1 extends Activity {

EditText fname;
EditText lname;
EditText email;
InputStream is;
TextView text;
List<NameValuePair> nameValuePairs;
byte[] data;
StringBuffer buffer;
public static int a = 0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    fname = (EditText)findViewById(R.id.name1);
    lname = (EditText)findViewById(R.id.name2);
    email = (EditText)findViewById(R.id.emailname);
    text= (TextView)findViewById(R.id.text);
    Button register = (Button) findViewById(R.id.register);
    register.setOnClickListener(new OnClickListener() 
    {
        public void onClick(View v) 
        {   
            if(fname.getText().length()== 0)
            {
                text.setText("Enter firstname");
            }
            else if(lname.getText().length()== 0)
            {
                text.setText("Enter Lastname");
            }
            else if(email.getText().length()== 0)
            {
                text.setText("Enter Email Id");
            }
            else{
                try{
                String a = fname.getText().toString().trim();
                String b = lname.getText().toString().trim();
                String c = email.getText().toString().trim();
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new
                HttpPost("http://android/android_user.php");
                nameValuePairs = new ArrayList<NameValuePair>(3);
                nameValuePairs.add(new BasicNameValuePair("fname", "parth"));
                nameValuePairs.add(new BasicNameValuePair("lname", "da"));
                nameValuePairs.add(new BasicNameValuePair("email", "asd"));
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,HTTP.UTF_16));


                HttpResponse response = httpclient.execute(httppost);
                HttpEntity entity = response.getEntity();
                is = entity.getContent();
                fname.setText("");
                lname.setText("");
                email.setText("");
                text.setText("");
                }catch(Exception e){
                Log.e("log_tag", "Error in http connection "+e.toString());
                text.setText("Connection error");
                }
            }
        }
    });
 }
 }    
     //Also my Manifest I have Included Permission for Internet.

当我在模拟器上输入数据时，我的代码不起作用@我的数据没有进入我的服务器数据库，而是一些空白数据进入了数据库。有人可以帮助我该怎么做。也请指出是什么我的代码中的错误。

Answer 1

我觉得这条线上有错误：

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,HTTP.UTF_16));

我换成了

UrlEncodedFormEntity URLEntity = new UrlEncodedFormEntity(nameValuePairs);
httppost.setEntity(URLEntity );

Answer 2

你试过了吗：

DefaultHttpClient客户端=新的DefaultHttpClient（）;

而不是HttpClient client = new DefaultHttpClient（）;

让我知道

Answer 3

我建议您检查网络通话的状态，可以通过以下方式进行检查：

int status = response.getStatusLine().getStatusCode();

如果您获得200作为状态代码，则说明它是成功的Web呼叫，否则出问题了。

Answer 4

@Parth Dani您的php文件中有一个错误...您实际上正在通过程序进行POST调用。
HttpPost httppost = new HttpPost("http://android/android_user.php");

并且您在Php代码中使用GEt ...您所要做的就是在您的Php代码中将GET替换为POST即可。
