操作超時

我有這個奇怪的錯誤：我甚至把無限超時試圖解決它。我說這很奇怪，因爲它曾經工作得很好，但現在，它不起作用，我不知道原因。錯誤：操作超時

這是調用Web服務的方法：最後一行是eclipse告訴我發生問題的地方。

public static final String ruta = "http://10.0.0.2:2731/Api/Usuario"; 

     HttpParams httpParameters = new BasicHttpParams(); 
     HttpConnectionParams.setConnectionTimeout(httpParameters, 0); 
     HttpConnectionParams.setSoTimeout(httpParameters, 0); 
     HttpConnectionParams.setTcpNoDelay(httpParameters, true); 

     HttpClient httpClient = new DefaultHttpClient(httpParameters); 
     HttpGet del = new HttpGet(ruta + "s"); 
     del.setHeader("content-type", "application/json"); 

     try { 
      HttpResponse resp = httpClient.execute(del);

當您嘗試通過網絡瀏覽器瀏覽網址時，url'http://10.0.0.2:2731/Api/Usuario'是否顯示任何響應？另外，'HttpGet del = new HttpGet（ruta +「s」）;'似乎將「s」連接到url字符串的末尾。所以，聲明結果爲'HttpGet del = new HttpGet（「http://10.0.0.2:2731/Api/Usuarios」）;'那是你的意思嗎？而且，您確定要將內容類型設置爲'application/json'，尤其是當您的請求是'GET'請求時？ – sandyiscool

對所有問題都是肯定的。第一個：瀏覽器中的網址不起作用，但這是針對模擬器的。通過localhost和's'連接，我可以看到內容。而且，因爲該服務給我的是一個json，所以我使用該內容類型 –

當你說'瀏覽器中的URL不起作用'時，你的意思是它也超時了嗎？或者它顯示任何錯誤信息？其次，服務器返回給你的數據的內容類型在響應的'content-type'標題中設置。你很可能不會在請求中發送json數據。所以，你通常不會設置。 – sandyiscool

您在代碼中將超時值設爲0。使用大於5000（毫秒）的值而不是0。 Ie HttpConnectionParams.setConnectionTimeout（httpParameters，5000）; HttpConnectionParams.setSoTimeout（httpParameters，5000）;

值爲0表示無限超時。 – sandyiscool

現在它給了我不同的錯誤09-05 23：47：39.550：E/ServicioRest（274）：org.apache.http.conn.ConnectTimeoutException：連接到/10.0.0.2:2731超時 –
