I need to access data from a webpage using several different post requests. For now I use:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://myurl");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("action", "search"));
nameValuePairs.add(new BasicNameValuePair("ndc", ndc));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
I need to sent this request using different values for the variable ndc. Would looping this lines be a good idea? If so, how to reuse the HttpClient and HttpPost variables?
If the URL needs to stay the same, then you should only change the values that need to sent.
for (int i=0; i<ndcArray.length;i++)
{
if(i==theNumberWhenURLhasToBeChanged) //adjust this condition based on your knowledge when the url has to be changed, lets say if i > theNumberWhenURLhasToBeChanged, then change the url...
{
httppost = new HttpPost(URLs[theNumberWhenURLhasToBeChanged]);
}
nameValuePairs.add(new BasicNameValuePair("ndc", ndcArray[i]));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
}
Note that: response will change each time, so bear in mind that you should save the response somewhere. And ndcArray[] can be replaced with any structure you want.

My problem is this: after the GET request authorization and save cookies trying to perform a POST request to add data, but the server responds with 500 code. What's funny, because if POST query string form in a browser, it is executed correctly. The code below.
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(site + "/admin/users/login_do/?login=admin&password=demo");
HttpResponse response = httpclient.execute(httpget);
List<Cookie> cookies = httpclient.getCookieStore().getCookies();
HttpPost httppost = new HttpPost(site + "/admin/news/add/5/item/do/");
httppost.addHeader("Cookie", "PHPSESSID="+cookies.get(0).getValue()+"; umicms_session="+cookies.get(1).getValue()+"; stat_id="+cookies.get(2).getValue());
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("active", "1"));
nameValuePairs.add(new BasicNameValuePair("name", "test"));
nameValuePairs.add(new BasicNameValuePair("data[new][anons]", "anno"));
nameValuePairs.add(new BasicNameValuePair("data[new][content]", "cont"));
nameValuePairs.add(new BasicNameValuePair("data[new][publish_time]", "1420202020"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
response = httpclient.execute(httppost);
StatusLine status = response.getStatusLine();
Log.d("my",String.valueOf(status.getStatusCode()));
Log.d("my",String.valueOf(status.getReasonPhrase()));
I've tried to run POST using HttpURLConnection, but also received 500 response.
Who can tell what might be the problem?
Problem solved. I Forgot to send csrf token with POST request and set Referer header
nameValuePairs.add(new BasicNameValuePair("csrf", csrf));
httppost.addHeader("Referer", referlink);
I have a code to make an httpPost, but i can't log using the parameters in the array, but if i make all the complete url i will log with no problem !, what am i missing ?
String URL = "http://domain.com/projexct/form.aspx"; //won't work
// String URL = "http://domain.com/projexct/form.aspx?user=aa&pass=11";
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(URL);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("user", "aa"));
nameValuePairs.add(new BasicNameValuePair("pass", "11"));
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpClient.execute(httpPost);
EDIT1
It doesn't throw and error, but if i use the parames in namevaluePairs it shows just the login page, if i use the URL commented it will actualy log in.
I would like to send an array of arrays from an android phone to a server. Is there any possibility to do this?
I expect something like this at the server side:
$_POST['items'] = array(
array('name'=>'joe', 'email'=>'joe#example.com'),
array('name'=>'jane', 'email'=>'jane#example.com')
);
Thx for your help!
Use HttpPost to send data to the server, and use json to create an array of array's. nameValuePairs will carry the data:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("items", jsonObject));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
Hope this helps...
I'm performing login on server using HttpPost method.
CommonsConnection.initHttpConnection();
HttpResponse response;
String contentOfMyInputStream;
HttpGet initPostMethod = new HttpGet("https://stat.volia.com:8443/ktvinet/index.jsp");
response = CommonsConnection.hc.execute(initPostMethod);
HttpPost Statistics = new HttpPost("https://stat.volia.com:8443/ktvinet/j_security_check");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("j_username", "username"));
nameValuePairs.add(new BasicNameValuePair("j_password", "password"));
nameValuePairs.add(new BasicNameValuePair("submit", "%C2%EE%E9%F2%E8"));
Statistics.setEntity(new UrlEncodedFormEntity(nameValuePairs));
response = CommonsConnection.hc.execute(Statistics);
HttpGet mainPage = new HttpGet("https://stat.volia.com:8443/ktvinet/main.do");
response = CommonsConnection.hc.execute(mainPage);
contentOfMyInputStream = EntityUtils.toString(response.getEntity());
The response I get - body of webpage - is like 1/5 part of webpage, which ends with "...".
Am I missing some parameter for httpclient ?
How are you examining the response? if you're looking int he debugger or something similar, it may well truncate long strings, try dumping it in a file.
Logcat displays only part of long string response.
I am executing the following post in Android:
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.example.com");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("account", "login"));
nameValuePairs.add(new BasicNameValuePair("email", "email#email.com));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
In the server side I return the cgi.request_method variable and it is GET.
Shouldn't it be POST? Am I missing something?
That code should initiate a POST, not a GET. I would guess that something on the server side is misconfigured.
My problem was send http instead of https
