my problem is that I don't know how to get verifier code from the redirected URL. The code is being echoed in the body.
HttpURLConnection igConnection = (HttpURLConnection) instagramURL.openConnection();
igConnection.setDoInput(true);
igConnection.setDoOutput(false);
if (igConnection.getResponseCode() == HttpURLConnection.HTTP_OK){
InputStream is = igConnection.getInputStream();
String response = "";
if (is != null){
BufferedReader in = new BufferedReader(new InputStreamReader(is));
StringBuffer input = new StringBuffer();
String line;
while ((line = in.readLine()) != null) {
input.append(line);
}
in.close();
System.out.println(input.toString());
}
}
What I do get is beginning like <html>...
I just wanted to refresh the accessToken in case it expires in the future (checking).
My authorization link is correct according to this pattern

Two ways to http request give another results one by JAVA code and second by copy element from website.
I am try to match them to same result!
When I use Java Code
private static boolean isValid(URL url, HttpURLConnection connection) {
BufferedReader reader;
String line;
StringBuffer responseContant = new StringBuffer();
try {
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setConnectTimeout(4000);
connection.setReadTimeout(4000);
int status = connection.getResponseCode();
if (status > 299) {
reader = new BufferedReader(new InputStreamReader(connection.getErrorStream()));
while ((line = reader.readLine()) != null)
responseContant.append(line);
reader.close();
} else {
reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
while ((line = reader.readLine()) != null)
responseContant.append(line);
reader.close();
return true;
}
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
It give me another value instead use inspect> copy> copy element
How it possible? and how to fix this issue?
Thanks guys!!
I want to scrape posts from Imgur.
Let's say we have this link(permalink): https://imgur.com/gallery/ZXjNfqu/comment/1717354251
I want to load this url via HttpURLConnection and read some data from content(HTML).
I have this code:
try{
//create connection
HttpURLConnection connection = (HttpURLConnection)(new URL(url)).openConnection();
connection.setRequestMethod("GET");
//get response
int responseCode = connection.getResponseCode();
if(responseCode == HttpURLConnection.HTTP_OK){
//read html
StringBuilder body = new StringBuilder();
try(var reader = new BufferedReader(new InputStreamReader(connection.getInputStream()))){
String line;
while((line = reader.readLine()) != null){
body.append(line);
}
}
//print html
System.out.println(body.toString());
}else{
//read error content
StringBuilder body = new StringBuilder();
try(var reader = new BufferedReader(new InputStreamReader(connection.getErrorStream()))){
String line;
while((line = reader.readLine()) != null){
body.append(line);
}
}
String bodyStr = body.toString().trim();
throw new Exception("Bad HTTP Request: " + responseCode +
" - " + connection.getResponseMessage() +
(bodyStr.isEmpty() ? "" : " - " + bodyStr));
}
}catch(Exception e){ e.printStackTrace(); }
Via HttpURLConnection I get only a part of the real page(what I see in browser). From HTML is missing at least image url and comments.
How I can get all content via HttpURLConnection?
P.S.: Is not necessary to use HttpURLConnection
Edit 1: I think it's because of javascript. But I'm not sure.
i am new to web services i am calling a web service that should returns JSON with the folliwng code - the problem is i am getting the response in xml format
when i am trying the same parameters using google rest api - the response is in jSON
any ideas what i am doing wrong ?
public static String getSFData(String urlSuffix) throws MalformedURLException, ProtocolException , IOException
{
String header = "Basic XXXXX";
URL url = new URL("https://api2.successfactors.eu/odata/v2/"+urlSuffix);
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("authorization",header);
connection.setRequestProperty("Content-Type", "application/json");
BufferedReader bf = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuffer stringBuffer = new StringBuffer();
String line;
while ((line = bf.readLine()) != null )
{
stringBuffer.append(line);
}
String response = stringBuffer.toString();
System.out.println("response"+response);
return response;
}
UPDATE
You could try the API URL like http://api2.successfactors.eu/odata/v2/User?
$format=json to get data in JSON.
Use StringBuilder instead of StringBuffer.
Try the following after set content type.
connection.connect();
int status = connection.getResponseCode();
switch (status) {
case 200:
BufferedReader bf = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuilder stringBuilder = new StringBuilder();
String line;
while ((line = bf.readLine()) != null) {
stringBuilder.append(line);
}
String response = stringBuilder.toString();
System.out.println("response : " + response);
}
I have implemented reCaptcha in the application I am working on. Somehow I am getting a blank reCaptcha response.
It works fine with localhost, but I am having a problem in upper environments like DEV, TEST. User response is being verified on server side (servlet).
Anyone having idea or faced similar problem ? Let me know if you need more info.
String userresponse = (String) request.getAttribute("g-recaptcha-response");
URL url = null;
HttpURLConnection conn = null;
String line, outputString = "";
try {
url = new URL(https://www.google.com/recaptcha/api/siteverify?secret=privateKey&response=userresponse);
conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
BufferedReader reader = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
while ((line = reader.readLine()) != null) {
outputString += line;
}
Log.debug("Google response is :- "+outputString);
} catch (IOException e) {
e.printStackTrace();
}
Is it possible to use HTTP API and perform HTTP Get request for Google maps in order to overcome the limits of using Geocoder API when requesting latitude and longitude of places?
Something like-
URL url = new URL("https://www.google.com/maps/place/Paris/");
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("GET");
System.out.println("Value" + connection.getResponseCode());
System.out.println(connection.getResponseMessage());
System.out.println("content"+connection.getContent());
or
URL url = new URL("https://www.google.com/maps/place/Paris/");
BufferedReader br = new BufferedReader(new InputStreamReader(url.openStream()));
String strTemp = "";
while (null != (strTemp = br.readLine())) {
System.out.println(strTemp);
}
Expecting the response to contain the lat and long of the place as in Google maps site, that way my client appears as a regular web client of google maps.
The Places API request has quota limit too, you can see the detail in this page: https://developers.google.com/places/webservice/usage
Also, you need an API key to do your Places API request, a sample way to do a Places API URL request in Android should be like this:
URL placeUrl = new URL("https://maps.googleapis.com/maps/api/place/textsearch/json?query=restaurants+in+Sydney&key=AddYourOwnKeyHere");
HttpURLConnection connection = (HttpURLConnection)placeUrl.openConnection();
connection.setRequestMethod("GET");
connection.connect();
responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader reader = null;
InputStream inputStream = connection.getInputStream();
StringBuffer buffer = new StringBuffer();
if (inputStream == null) {
// Nothing to do.
return null;
}
reader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) {
buffer.append(line + "\n");
}
if (buffer.length() == 0) {
return null;
}
Log.d(TAG, buffer.toString());
}
else {
Log.i(TAG, "Unsuccessful HTTP Response Code: " + responseCode);
}
You should do this URL request in background thread, for example, in the doInBackground() method of AsyncTask.
