[英]org.apache.http.client.ClientProtocolException appears when HttpClient executes
我想通过POST请求向服务器发送一些数据。 我的代码:
protected Void doInBackground(Void... arg)
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost post = new HttpPost("https://money.yandex.ru/oauth/authorize");
post.addHeader("Host", "m.sp-money.yandex.ru");
post.addHeader("Content-Type", "application/x-www-form-urlencoded");
post.addHeader("Content-Length", "154");
//data back from server
String responseBackFromServer = "";
try
{
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("client_id", "51"));
pairs.add(new BasicNameValuePair("response_type", "code"));
pairs.add(new BasicNameValuePair("redirect_uri", "https://vk.com/"));
pairs.add(new BasicNameValuePair("scope", "account-info"));
post.setEntity(new UrlEncodedFormEntity(pairs));
HttpResponse server_response = httpclient.execute(post);//!!!exception is appearing here!!!
responseBackFromServer = EntityUtils.toString(server_response.getEntity());
}
catch (ClientProtocolException e)
{
e.printStackTrace();
Log.d(LOG_TAG, "" + e);
}
}
但是在“ HttpResponse server_response = httpclient.execute(post);”上 出现字符串ClientProtocolException。 我该如何解决?
尝试删除所有的addHeader语句。 该框架应为您添加它们。
