這是我的Java代碼

HttpGet httpGet = new HttpGet("http://myip:8084/rest/loc/test/7225"); 
    HttpParams params = new BasicHttpParams(); 
    HttpConnectionParams.setStaleCheckingEnabled(params, false); 
    HttpConnectionParams.setConnectionTimeout(params, 30000); 
    HttpConnectionParams.setSoTimeout(params, 30000); 
    HttpClient httpClient = new DefaultHttpClient(params); 
    HttpResponse httpResponse = httpClient.execute(httpGet); 
    InputStream inputStream = httpResponse.getEntity().getContent(); 
    BufferedReader bufferedReader = new BufferedReader(
      new InputStreamReader(inputStream)); 
    StringBuilder responseStr = new StringBuilder(); 
    String responseLineStr = null; 
    while ((responseLineStr = bufferedReader.readLine()) != null) { 
     responseStr.append(responseLineStr); 
    }

這是我的清單文件權限列表

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> 
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/> 
<user-permission android:name="android.permission.INTERNET"/> 
<user-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

什麼可以這樣做的原因，服務工作
感謝

您是在模擬器上還是在設備上檢查此問題？你有沒有在瀏覽器上檢查該網址？還檢查它是否需要任何身份驗證或參數，並且您正在發送.. –

我在模擬器上檢查此問題，並且此網址在我的瀏覽器中正常工作，並且我也爲此代碼提供了相同的URL。沒有從Web服務端的身份驗證，但我不知道有關android部分。謝謝 – user1573690

不，不像android需要發送Rest（任何類型的api/web服務）的任何身份驗證的情況。嘗試調試代碼並檢查一次。 –

而是提供與myip模擬器，給10.0.2.2。這應該工作。

它也沒有工作Pradeep – user1573690

我解決了這個問題，這是一個權限問題，它真的像一個語法問題，你都可以看到它在我的第一篇文章，在清單文件

<user-permission android:name="android.permission.INTERNET"/>

是錯誤的，它應該是

<uses-permission android:name="android.permission.INTERNET"/>

感謝您的回覆，並對我的錯誤感到抱歉
