I'm trying to login to facebook using httpurlconnect. I think i need to get the cookie from facebook.com/ajax/bz and then pass it along with my login attempt but maybe not. The response just takes me back to the login page and I never log in. Can someone help me get this to log in?
I do not want to use the official API.

It doesn't matter that you want to do it; according to the Automated Data Collection Terms, it's not allowed. You app/server can be blocked. Don't do this. Instead, just use the Graph API and all documented features.

set the redirect turn off after that you will get the json response. So in your java code set redirect false.
connection.setInstanceFollowRedirects(false);
I am facing a problem while using POST Method in Java nowadays. I am receiving
Exception in thread "main" java.lang.RuntimeException: Server returned HTTP response code: 411 for URL.
I couldn't find any available document anywhere. None of them were useful. How do I fix it?
My code
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class req {
public static void main(String[] args) {
sendPostRequest(requestURL);
}
private static String sendPostRequest(String requestUrl) {
StringBuilder jsonString = new StringBuilder();
try {
URL url = new URL(requestUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
byte[] data = requestUrl.getBytes("UTF-8");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
connection.setRequestProperty("Content-Length", String.valueOf(data.length));
connection.setRequestProperty("Authorization", "Basic " + "usename:password");
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
jsonString.append(line);
}
br.close();
connection.disconnect();
} catch (Exception e) {
throw new RuntimeException(e.getMessage());
}
return jsonString.toString();
}
}
Perfectly working method:
public String sendPostRequest(String requestURL, HashMap<String, String> postDataParams) {
URL url;
String response = "";
try {
url = new URL(requestURL);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(15000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getPostDataString(postDataParams));
writer.flush();
writer.close();
os.close();
int responseCode=conn.getResponseCode();
if (responseCode == HttpsURLConnection.HTTP_OK) {
BufferedReader br=new BufferedReader(new InputStreamReader(conn.getInputStream()));
response = br.readLine();
}
else {
response="Error Registering";
}
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
private String getPostDataString(HashMap<String, String> params) throws UnsupportedEncodingException {
StringBuilder result = new StringBuilder();
boolean first = true;
for(Map.Entry<String, String> entry : params.entrySet()){
if (first)
first = false;
else
result.append("&");
result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
result.append("=");
result.append(URLEncoder.encode(entry.getValue(), "UTF-8"));
}
return result.toString();
}
If you are returning a JSON in your response:
public JSONObject getPostResult(String json){
if(!json.isEmpty()) {
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON_ERROR", "Error parsing data " + e.toString());
}
}
return jObj;
}
If you are still having trouble, maybe this will help. I did not test, machine does not have java installed.
You should also set all other headers that you need.
public static String PostRequest(String requestUrl, String username, String password) {
StringBuilder jsonString = new StringBuilder();
HttpURLConnection connection = null;
try {
URL url = new URL(requestUrl);
connection = (HttpURLConnection)url.openConnection();
byte[] authData = Base64.encode((username + password).getBytes());
connection.setRequestMethod("POST");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestProperty("Authorization", "Basic " + new String(authData));
connection.setRequestProperty("Content-Length", String.valueOf(authData.length));
try (DataOutputStream writer = new DataOutputStream(connection.getOutputStream())) {
writer.writeBytes("REPLACE ME WITH DATA TO BE WRITTEN");
writer.flush();
}
try (BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()))) {
String data = null;
while ((data = reader.readLine()) != null) {
jsonString.append(data);
}
}
} catch (IOException ex) {
//Handle exception.
} finally {
if (connection != null)
connection.disconnect();
}
return jsonString.toString();
}
You should send empty data in body if you are using post method.
For example if you are using json data you need to send "{}"
public void Post() throws Exception {
StringBuffer d = new StringBuffer();
String da = "ClearanceDate=2020-08-31&DepositeDate=2020-08-31&BankTransactionNo=UATRYU56789";
URL url = new URL("https://abcd/AddReceipt?" + da);
byte[] postDataBytes = ("https://abcd/AddReceipt?" + da).toString()
.getBytes("UTF-8");
System.out.println("Data--" + postDataBytes);
HttpsURLConnection con = (HttpsURLConnection) url.openConnection();
// con.setRequestProperty("User-Agent",
// "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");
con.setRequestMethod("POST");
con.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
con.setRequestProperty("Content-Length",
String.valueOf(postDataBytes.length));
con.setRequestProperty(
"Authorization",
"Bearer "
+ "o731WGgp1d913ZOYivnc55yOg0y1Wk7GsT_mnCUKOJf1VChYOdfRjovAxOhyyPKU93ERue6-l9DyG3IP29ObsCNTFr4lGZOcYAaR96ZudKgWif1UuSfVx4AlATiOs9shQsGgb1oXN_w0NRJKvYqD0LLsZLstBAzP1s5PZoaS9c6MmO32AV47FUvxRT6Tflus5DBDHji3N4f1AM0dShbzmjkBCzXmGzEDnU6Jg1Mo5kb884kParngKADG5umtuGbNzChQpMw_A0SyEYaUNh18pXVmnNhqM3Qx5ZINwDEXlYY");
con.setRequestProperty("Accept", "application/json");
con.setDoInput(true);
con.setDoOutput(true);
con.getOutputStream().write(postDataBytes);
int status = con.getResponseCode();
System.out.println("Response status: " + status + "|"
+ con.getResponseMessage());
BufferedReader in = new BufferedReader(new InputStreamReader(
con.getInputStream()));
String inputLine;
StringBuffer content = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
content.append(inputLine);
}
in.close();
con.disconnect();
System.out.println("Response status: " + status);
System.out.println(content.toString());
System.out.print("Raw Response->>" + d);

It was the way I issued the GET. I had to go to a lower level on App Engine and use FetchOptions This worked for me, hopefully it will help someone else.
URL url = new URL(request);
HTTPRequest req = new HTTPRequest(url, HTTPMethod.GET);
req.addHeader(new HTTPHeader("Authorization", "Bearer " + bearerToken));
HTTPResponse response = URLFetchServiceFactory.getURLFetchService().fetch(req);
System.out.println(new String(response.getContent()));
I have used this tutorial to try to login to a website from the company I am doing my internship at: http://www.mkyong.com/java/how-to-automate-login-a-website-java-example/
However, It is not logging in, since the URL when you're logged in to the site is the same as when you're not logged in. So all that happens is me adding the data to the fields, and then the page refreshes, with nothing happening. Can anyone tell me how I am supposed to continue?
Thanks
