通過HTTP GET將數據發送到PHP服務器

我建立一個應用程序中，用戶可以選擇他/她的性別，喜歡的食物，他們的憤怒，最喜歡的顏色，他們的年齡等..通過HTTP GET將數據發送到PHP服務器

我通過這些數據到我的最終活動與意圖。現在我試圖將答案發送到一個PHP服務器（工作正常）並得到一個答案（哪個城市最適合你）

這是我的代碼，我不知道它是什麼問題（我已經添加到連接到互聯網）當我運行的應用程序，直到被點擊的最後一項活動，它工作正常的權限，那麼它強制關閉應用程序

public class result extends AppCompatActivity { 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.result); 


    TextView result = (TextView)findViewById(R.id.result); 

    final String gender; 
    Intent a = getIntent(); 
    gender = a.getStringExtra("gender"); 
    final String anger; 
    Intent b = getIntent(); 
    anger = b.getStringExtra("hate"); 
    final String food; 
    Intent c = getIntent(); 
    food = c.getStringExtra("food"); 
    final String gettowork; 
    Intent d = getIntent(); 
    gettowork = d.getStringExtra("gotowork"); 
    final String settelment; 
    Intent ee = getIntent(); 
    settelment = ee.getStringExtra("house"); 
    final String actor; 
    Intent f = getIntent(); 
    actor = f.getStringExtra("star"); 
    final String weather; 
    Intent g = getIntent(); 
    weather = g.getStringExtra("weather"); 
    final String weekend; 
    Intent h = getIntent(); 
    weekend = h.getStringExtra("weekend"); 
    final String color; 
    Intent j = getIntent(); 
    color = j.getStringExtra("color"); 
    final String age; 
    Intent i10 = getIntent(); 
    age = i10.getStringExtra("age"); 


HttpClient httpclient = new DefaultHttpClient(); 
HttpGet httpget = new HttpGet("http://test123.com/games/whichcity/app/check-form.php?gender=" + gender + "&anger=" + anger + "&food=" + food + "&gettowork=" + gettowork + "&settlement=" + settelment + "&actor=" + actor + "&weather=" + weather + "&weekend=" + weekend + "&color=" + color + "&age=" + age); 
    HttpResponse response = null; 
    try { 
     response = httpclient.execute(httpget); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    HttpEntity entity = response.getEntity(); 
    try { 
     InputStream webs = entity.getContent(); 
     BufferedReader reader = new BufferedReader(new InputStreamReader(webs,"iso-8859-1"),8); 
     result.setText(reader.readLine()); 
    } catch (IOException e) { 
     e.printStackTrace();

你能發佈你收到的錯誤嗎？ – tpk

我們看到出了什麼問題。你也可以看到它。而你沒有告訴你的應用真的發生了什麼。那麼，如果你看看LogCat，你就會知道出了什麼問題。張貼相關的行。 – greenapps

執行此代碼後有什麼問題？發佈logcat的相關行。 –

，因爲你正試圖執行UI線程聯網操作您收到此異常。除此之外，您可以在另一個線程中執行網絡操作，或者實施一些更好的方法，最終將操作置於另一個線程中。這些更好的方法是使用AsyncTask或使用Volley。我肯定會爲Volley投票，因爲它簡單而整潔。

GET操作實施抽射，

// Instantiate the RequestQueue. 
RequestQueue queue = Volley.newRequestQueue(this); 
String url ="http://test123.com/games/whichcity/app/check-form.php?gender=" + gender + "&anger=" + anger + "&food=" + food + "&gettowork=" + gettowork + "&settlement=" + settelment + "&actor=" + actor + "&weather=" + weather + "&weekend=" + weekend + "&color=" + color + "&age=" + age; 

// Request a string response from the provided URL. 
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, 
      new Response.Listener<String>() { 
    @Override 
    public void onResponse(String response) { 
     //handle response from server 
     result.setText(response); 
    } 
}, new Response.ErrorListener() { 
    @Override 
    public void onErrorResponse(VolleyError error) { 
     //handle error 
     result.setText("That didn't work!"); 
    } 
}); 
// Add the request to the RequestQueue. 
queue.add(stringRequest);

中序凌空工作，你應該在你的gradle產出增加的依賴。在您的Gradle文件（模塊：應用程序）中，在依賴關係中添加compile 'com.android.volley:volley:1.0.0'。

dependencies { 
    compile 'com.android.volley:volley:1.0.0' 
}

編碼愉快！
