信息发送到服务器，java.net.SocketException异常：socket失败：EACCES（拒绝）

Question

我得到的错误

java.net.SocketException异常：socket失败：EACCES（拒绝）

这是我的方法来发布数据到服务器

public void postData(String stuff){ 
    //Create a new HTTPClient and Post Header 
    URL url; 
    HttpURLConnection con = null; 
    status.setText("In post"); 
    try{ 
     url = new URL("http://myaddress/gpsin"); 
     con = (HttpURLConnection)url.openConnection(); 
     con.setDoOutput(true); 
     con.setRequestMethod("POST"); 
     con.setRequestProperty("Content-Type","application/x-www-form-urlencoded; charset=UTF-8"); 
     con.connect(); 

     //Send Request 
     DataOutputStream wr = new DataOutputStream(con.getOutputStream()); 
     wr.writeBytes((stuff)); 
     wr.flush(); 
     wr.close(); 

     InputStream is; 
     int response = con.getResponseCode(); 
     if(response >= 200 && response<= 399){ 
      //return success 
      status.setText("Success!"); 
     }else{ 
      //return fail 
      status.setText("Fail"); 
     } 
    } catch (Exception e){ 
     e.printStackTrace(); 
     status.setText("In catch"); 
    }finally{ 
     if(con!=null)con.disconnect(); 
    } 
}

我已经做了google搜索，像样的数目，但所有我能找到的人乱放的权限线在清单

尝试程序，但不调用.connect（）。这些文档在这方面有点混乱，因为它告诉你返回的URLConnection在创建时没有连接，但HttpURLConnection样本从不显示实际的.connect（）调用。这可能是因为你已经连接，并且随后对.connect（）的调用正试图在已经完成连接时建立连接，导致幕后出现奇怪的权限问题。 - 拉里希弗
