I am trying to write an Android app that on startup automatically authenticates the user at a preset webpage I have no control over. I tried it using a POST-Request (following a GET-Request in order to get the cookies needed for authentication) but I ended up receiving a 301 - Moved Permanently Error.
However, the same code worked perfectly in Java.
InputStream inputStream = null;
int length = 100;
try {
URL url = new URL(site);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setRequestProperty("Host", host);
conn.setRequestProperty("User-Agent", "Mozilla/5.0 (X11; Linux x86_64; rv:53.0) Gecko/20100101 Firefox/53.0");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
conn.setRequestProperty("Accept", "*/*");
conn.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
conn.setRequestProperty("Accept-Encoding", "gzip, deflate, br");
conn.setRequestProperty("X-Requested-With", "XMLHttpRequest");
conn.setRequestProperty("Referer", referer);
conn.setRequestProperty("Connection", "keep-alive");
conn.setRequestProperty("Cookie", cookie);
conn.setInstanceFollowRedirects(false);
conn.setDoInput(true);
conn.setDoOutput(true);
//setting parameters needed for login
List<AbstractMap.SimpleEntry> params = new ArrayList<>();
params.add(new AbstractMap.SimpleEntry("type", type));
params.add(new AbstractMap.SimpleEntry("console", console));
params.add(new AbstractMap.SimpleEntry("login[password]", password));
params.add(new AbstractMap.SimpleEntry("login[mail]", username));
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
//write converted parameters
writer.write(getQuery(params));
writer.flush();
writer.close();
os.close();
conn.connect();
int response = conn.getResponseCode();
Log.d(TAG, "The response is: " + response + "\n" + conn.getResponseMessage());
inputStream = conn.getInputStream();
// Convert the InputStream into a string
String contentAsString = convertInputStreamToString(inputStream, length);
Log.d(TAG, "Content of Webpage: " + contentAsString);
} finally {
if (inputStream != null) {
inputStream.close();
}
}

I want to delete the API from url : "http://dublr024vm.devlab.ibm.com:60633/B2BiAPIs/svc/cadigitalcertificates/_id:tibco_ssl" , I am getting java.io.IOException: Server returned HTTP response code: 403 for URL. I have passed the correct authentication details too.
Below is the part of my code:
public static void call_me() throws Exception {
InputStream is = null;
String url = "http://dublr024vm.devlab.ibm.com:60633/B2BiAPIs/svc/cadigitalcertificates/_id:tibco_ssl";
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
con.addRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.29 Safari/537.36");
con.setDoOutput(true);
System.setProperty("http.agent", "Chrome");
// optional default is DELETE
con.setRequestMethod("DELETE");
//add request header
con.setRequestProperty("Content-Type", "application/json");
con.setRequestProperty("Accept", "application/json");
byte[] message = "admin:password".getBytes("UTF-8");
String encoding = DatatypeConverter.printBase64Binary(message);
con.setRequestProperty("Authorization", "Basic "+new String(encoding));
con.connect();
is = obj.openConnection().getInputStream();
int responseCode = con.getResponseCode();
System.out.println("\nSending 'DELETE' request to URL : " + url);
System.out.println("Response Code : " + responseCode);
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String line, responseText = "";
while ((line = br.readLine()) != null) {
System.out.println(line);
responseText += line;
}
br.close();
con.disconnect();
}

The Access-Token request, I do in a similar way, is working perfectly fine and gives me a valid token.
What am I doing wrong?
EDIT. Changed dateformat in URL, see comments.
All good day!
Example code:
try {
URL object = new URL(url);
HttpURLConnection con = (HttpURLConnection) object.openConnection();
con.setDoOutput(true);
con.setDoInput(true);
con.setRequestProperty("Content-Type", "application/json; charset=utf-8");
con.setRequestProperty("Accept", "application/json; charset=utf-8");
con.setRequestMethod("POST");
OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(json);
wr.flush();
InputStream inputStream = con.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line = "";
while ((line=reader.readLine()) != null) {
response += "\n" + line;
}
How to get the status of a response?
Please, help!
con.getResponseCode();` // get status
I'm trying to post a file from local to another platform over a switch. When i do it with DefaultHttpClient there is no problem.
HttpParams params = new BasicHttpParams();
params.setParameter(ConnRoutePNames.LOCAL_ADDRESS, InetAddress.getByName(interfaceIp));
DefaultHttpClient httpClientPost = new DefaultHttpClient(params);
But i have to do it with HttpURLConnection. Is there a way to do this?
for example:
httpConn = (HttpURLConnection) url.openConnection(myHttpParams);
here is my HttpUrlConn codes
url = new URL(baseUrl+"/html/uploadimage.cgi");
httpConn = (HttpURLConnection) url.openConnection();
httpConn.setUseCaches(false);
httpConn.setDoOutput(true); // indicates POST method
httpConn.setDoInput(true);
httpConn.setRequestProperty("Content-Type", "multipart/form-data; boundary=" +"----WebKitFormBoundary"+boundary);
httpConn.setRequestProperty("Host", "192.168.1.1");
httpConn.setRequestProperty("Connection", "keep-alive");
httpConn.setRequestProperty("Content-Length", "16551361");
httpConn.setRequestProperty("Cache-Control", "max-age=0");
httpConn.setRequestProperty("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
httpConn.setRequestProperty("Origin", "http://192.168.1.1");
httpConn.setRequestProperty("Upgrade-Insecure-Requests", "1");
httpConn.setRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36");
httpConn.setRequestProperty("Referer", baseUrl + "/html/advance.html");
httpConn.setRequestProperty("Accept-Encoding", "gzip, deflate");
httpConn.setRequestProperty("Accept-Language", "tr-TR,tr;q=0.8,en-US;q=0.6,en;q=0.4");
String cookie = "Username="+ username +"; " +
"Password="+ cyreptedPassword +"; Language=tk; " +
"username="+ username +"; " +
"SessionID_R3="+ sessionID +"; activeMenuID=maintain_settings; activeSubmenuID=device_mngt";
httpConn.setRequestProperty("Cookie", cookie);
httpConn.setAllowUserInteraction(true);
httpConn.setConnectTimeout(9999*9999999);
outputStream = httpConn.getOutputStream();
writer = new PrintWriter(new OutputStreamWriter(outputStream, "UTF-8"), true);
thanks for all.
HttpUrlConnection does not use http params, but it uses proxy.
