android post数据到服务器异常
项目中获取服务器信息时候，需要把用户的id和一些数据post到服务器，然后才能获取到服务器返回信息，post的方法如下。
public String postDataToWeb(String url,Map<String, String> data){
HttpClient httpClient=new DefaultHttpClient();
HttpPost httpPost=new HttpPost(url);
httpClient.getParams().setParameter(
CoreConnectionPNames.CONNECTION_TIMEOUT, 7000);
List<BasicNameValuePair> lists=new ArrayList<BasicNameValuePair>();
for(Map.Entry<String, String> entry : data.entrySet()){
BasicNameValuePair nameValuePairs = new BasicNameValuePair(entry.getKey(), entry.getValue());
lists.add(nameValuePairs);
}
try {
HttpEntity entity=new UrlEncodedFormEntity(lists, "utf-8");
httpPost.setEntity(entity);
HttpResponse response=httpClient.execute(httpPost);
if(response.getStatusLine().getStatusCode()==200){
String s=EntityUtils.toString(response.getEntity());
return s;
}
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "";
}
可是有时候多次点击获取信息的时候，会报异常，

网上找了下都说的不太清楚，求大神赐教！！报错的代码是String s=EntityUtils.toString(response.getEntity());这行！！！
android 服务器 post 异常
[解决办法]
自定义一个方法来代替String s=EntityUtils.toString(response.getEntity()); 这句
String str = getContent(httpResponse);
方法：
public static String getContent(HttpResponse response) {
BufferedReader in = null;
String page = "";
try {
in = new BufferedReader(new InputStreamReader(response.getEntity()
.getContent()));
StringBuffer sb = new StringBuffer("");
String line = "";
while ((line = in.readLine()) != null) {
sb.append(line);
}
page = sb.toString();
} catch (Exception e) {
e.printStackTrace();
} finally {
if (in != null)
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return page;
}
我没遇到过你那样的问题，不过你可以试试这个方法
