private HttpResponse doResponse(String url) {
HttpClient httpclient = new DefaultHttpClient(getHttpParams());
HttpResponse response = null;
try {
HttpGet httpget = new HttpGet(url);
response = httpclient.execute(httpget);
} catch (Exception e) {
Log.e(TAG, e.getLocalizedMessage(), e);
}
return response;
}
@Override
protected String doInBackground(String... urls) {
// TODO: attempt authentication against a network service.
String url = urls[0];
String result ="";
try {
HttpResponse response=doResponse(url);
result = inputStreamToString(response.getEntity().getContent());
//throws IllegalStateException: Content has been consumed
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
Log.e(TAG, e.getLocalizedMessage(), e);
}
return result;
}
线
result = inputStreamToString(response.getEntity().getContent());
抛出
IllegalStateException: Content has been consumed
即使我以前没有得到内容。
我想知道我的代码中的女巫部分在使用内容之前
response.getEntity().getContent();
我在Samsung Galaxy Tab 2上
运行Android 4.1.1
最佳答案
确保只调用一次getContent()
。确认您没有在inputStreamToString()
方法中调用它。 getContent()
返回一个输入流,每个连接只能返回一次输入流。
Documentation:
getContent()
创建实体的新InputStream对象。多次返回同一个InputStream对象是编程错误。如果多次调用此方法,则不可重复的实体将引发异常。
