============問題描述============java
想用數據庫作一個登陸驗證的功能，服務器端響應正常，json數據包 {"ret":1,"num":123}
ret是登陸正常時的狀態值，num是號碼：123
url是192.168.1.3:8080/web/getActInfo
params：num=123
經過logcat發如今httpGet中拋出了一個異常，可是搞不明白！！痛苦了一下午求點撥！
public String httpGet(String url, String params) throws Exception
{
String response = null;
if (null!=params&&!params.equals(""))
{
url += "?" + params;
}
int timeoutConnection = 8000;
int timeoutSocket = 10000;
HttpParams httpParameters = new BasicHttpParams();// Set the timeout in milliseconds until a connection is established.
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);// Set the default socket timeout (SO_TIMEOUT) // in milliseconds which is the timeout for waiting for data.
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
HttpClient httpClient = new DefaultHttpClient(httpParameters);
HttpGet httpGet = new HttpGet(url);
try
{
HttpResponse httpResponse = httpClient.execute(httpGet);
int statusCode = httpResponse.getStatusLine().getStatusCode();
if (statusCode == HttpStatus.SC_OK) //SC_OK = 200
{
response = EntityUtils.toString(httpResponse.getEntity());
}
else
{
response = "狀態碼"+statusCode;
}
} catch (Exception e)
{
throw new Exception(e);
}

網絡請求不能放在主線程
開個線程獲取數據
============解決方案2============git
主線程不能作網絡請求，你把這些網絡操做放在新開的線程裏或者異步任務裏
