您好我正试图从我的MVC asp.net获取一个json对象。
我收到错误
StringBuilder url = new StringBuilder(URL);
HttpGet get = new HttpGet (url.toString());
HttpResponse r = client.execute(get);
int status = r.getStatusLine().getStatusCode();
if(status == 200)
{
HttpEntity e = r.getEntity();
String data = EntityUtils.toString(e);
JSONArray timeline = new JSONArray(data);
JSONObject last = timeline.getJSONObject(0);
return last;
}
else
{
Toast.makeText(Authenticate.this, "error", Toast.LENGTH_LONG);
return null;
}
错误:
Java.IOException。
public class Read extends AsyncTask <String,Integer,String>
{
@Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
try{
json = Verify();
return json.getString(params[0]);
}
catch (ClientProtocolException e)
{
}
catch (IOException e)
{
}
catch (JSONException e)
{
}
return null;
}
我目前通过localhost连接。
问题发生在这一行: HttpResponse r = client.execute(get);
它没有执行,VM上的应用程序崩溃了。
我修改了代码看起来像这样但仍然得到同样的错误:
public JSONObject Verify(HttpResponse r) throws ClientProtocolException, IOException, JSONException
{
//StringBuilder url = new StringBuilder(URL);
//Adds the pin and IMEI.
//url.append(b);
//HttpGet get = new HttpGet (url.toString());
//HttpResponse r = client.execute(get);
int status = r.getStatusLine().getStatusCode();
if(status == 200)
{
HttpEntity e = r.getEntity();
String data = EntityUtils.toString(e);
JSONArray timeline = new JSONArray(data);
JSONObject last = timeline.getJSONObject(0);
return last;
}
else
{
Toast.makeText(Authenticate.this, "error", Toast.LENGTH_LONG);
return null;
}
}
public class Read extends AsyncTask <String,Integer,String>
{
@Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
try{
HttpResponse r = client.execute(get);
json = Verify(r);
return json.getString(params[0]);
}
catch (ClientProtocolException e)
{
}
catch (IOException e)
{
}
catch (JSONException e)
{
}
return null;
}

如果没有更多信息,很难说,但您可能正在UI线程上运行此操作,这是不允许的。如果是这种情况,您将需要使用AsynTask。
