我已經使用xampp設置了一個MySql服務器,我正在創建一個連接到數據庫的android應用程序。我可以使用MYSQL Workbench和ODBC連接器從異地進行連接,並巧妙地無誤地推/拉數據。當連接到EMULATED手機時,我得到「org.apache.http.conn.httphostconnectexception連接到http://x.x.x.x:88/mobile.php拒絕」在DDMS。任何想法,爲什麼這種情況正在發生???獲取「org.apache.http.conn.httphostconnectexception連接到http:// xxxx:88/mobile.php拒絕

允許互聯網是沒有開啓......它是現在,只是驗證,清洗和重新啓動,現在我得到「ClientProtocolException」。

public void getData() { 
    String result = ""; 
    InputStream isr = null; 
    try { 
     HttpClient httpclient = new DefaultHttpClient(); 
     ///external ip address not local host or trying inside a local network 
     HttpPost httpost = new HttpPost("http://x.x.x.x:88/mobile.php"); 
     HttpResponse response = httpclient.execute(httpost); 
     HttpEntity entity = response.getEntity(); 
     isr = entity.getContent(); 
    } catch (Exception e) { 
     Log.e("log.tag", "Error in http connection " + e.toString()); 
     resultView.setText("Could not connect to Database"); 
    } 
    try { 
     BufferedReader reader = new BufferedReader(new InputStreamReader(
       isr, "iso=8859-1"), 8); 
     StringBuilder sb = new StringBuilder(); 
     String line = null; 
     while ((line = reader.readLine()) != null) { 
      sb.append(line + "\n"); 
     } 
     isr.close(); 

     result = sb.toString(); 
    } catch (Exception e) { 
     Log.e("log.tag", "Error converting result " + e.toString()); 
    } 
    try { 
     String s = ""; 
     JSONArray jArray = new JSONArray(result); 
     for (int i = 0; i < jArray.length(); i++) { 
      JSONObject json = jArray.getJSONObject(i); 
      s = s + "User :" + json.getString("UserName"); 
     } 
     resultView.setText(s); 
    } catch (Exception e) { 
     Log.e("log.tag", "Error Parsing Data " + e.toString()); 
    }

是你確定你的Manifest有INTERNET權限嗎? – 2014-11-05 22:09:22

確保服務器防火牆未被阻止。或者也許是殺毒軟件。 – 2014-11-05 22:19:02

服務器防火牆也沒有路由器被阻塞,可以通過ODBC和MYSQL Workbench打通,Internet權限沒有被添加,現在是。現在我得到「ClientProtocolException」。 – Glenn 2014-11-05 22:25:40

步驟,使這項工作:

  1. 添加INTERNET權限到您的清單
  2. 確保沒有防火牆或代理服務器從服務器端阻塞
  3. 添加httpPost.setHeader("Accept", "application/json");httpPost聲明
