httpConn.getResponseCode() is 400 and httpConn.getResponseMessage() is Bad Request.
I have tested this request with the URL generated in this class on Postman.
it works correctly.
so I am sure about url and token is correct.
It creates an Empty file successfully.
But as I mentioned the response status is 400 and Bad Request.
I am not sure what is wrong with the following class

I am having troubles with posting http POST request in java. All the details are correct, but I am getting error for not valid API key.
I tried everything, and read every single post that I could find here but still no clue what is incorrect.
Here's the code:
String urlString = "https://example.com/";
url = new URL(urlString);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("POST");
urlConnection.setDoOutput(true);
String data = URLEncoder.encode("api_key", "UTF-8")
+ "=" + URLEncoder.encode("xxxxx", "UTF-8");
urlConnection.connect();
OutputStreamWriter wr = new OutputStreamWriter(urlConnection.getOutputStream());
wr.write(data);
wr.flush();
try{
stream = urlConnection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(stream, "UTF-8"), 8);
String result = reader.readLine();
System.out.println(result);
} catch (IOException e){
throw(new Throwable("An error occured:\n" + e));
}
I'm trying to send a POST request to grab comments but it doesn't work in Java while it does work with postman.
I get an 403 Forbidden error, but on postman it retrieves the data i need just fine..
Here's the Java code I'm trying to use to replicate the behavior.
String targetUrl = YOUTBE_COMMENTS_AJAX_URL;
String urlParameters = "action_load_comments=1&order_by_time=True&filter=jBjXVrS8nXs";
String updatedURL = targetUrl + "?" + urlParameters;
URL url = null;
InputStream stream = null;
HttpURLConnection urlConnection = null;
try {
url = new URL(updatedURL);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("content-type", "multipart/form-data");
urlConnection.setRequestProperty("user-agent", "USER_AGENT");
urlConnection.setDoOutput(true);
String data = URLEncoder.encode("video_id", "UTF-8")
+ "=" + URLEncoder.encode(youtubeId, "UTF-8");
data += "&" + URLEncoder.encode("session_token", "UTF-8") + "="
+ URLEncoder.encode(xsrfToken, "UTF-8");
data += "&" + URLEncoder.encode("page_token", "UTF-8") + "="
+ URLEncoder.encode(pageToken, "UTF-8");
urlConnection.connect();
OutputStreamWriter wr = new OutputStreamWriter(urlConnection.getOutputStream());
wr.write(data);
wr.flush();
stream = urlConnection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(stream, "UTF-8"), 8);
String result = reader.readLine();
return result;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
}
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
Here's an example of what postman is sending in their headers
It seems like your problem is here (see inline comments):
DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
wr.writeBytes(urlParameters);
// you wrote your URL parameters into Body
wr.flush();
wr.close();
//You closed your body and told server - you are done with request
conn.getOutputStream().write(postDataBytes);
// you wrote data into closed stream - server does not care about it anymore.
You have to append your urlParameters directly to the URL when you open it
Then you have to write your Form Data into body as you do:
conn.getOutputStream().write(postDataBytes);
and then close output stream
I am trying to download file from a https website using java HttpsURLConnection with the Authorization header. I keep getting back the 401 response code, however, I don't have a problem using the credentials to download it through a web browser. Please help to take a look what might be wrong with my code:
File file = new File("c:/filename");
String src = "https://www.example.com/filename";
try {
file.createNewFile();
URL url = new URL(src);
HttpsURLConnection urlConnection = (HttpsURLConnection)url.openConnection();
String userCredentials = "username:password";
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));
urlConnection.addRequestProperty ("Authorization", basicAuth);
urlConnection.connect();
System.out.println("code" + urlConnection.getResponseCode());
InputStream in = urlConnection.getInputStream();
OutputStream out = new FileOutputStream(file);
int d;
while ((d = in.read()) != -1) {
out.write(d);
}
in.close();
out.close();
} catch (Exception e) {
System.err.println("Failed to get the file from source. " + e);
if (file.exists()) {
file.delete();
}
}
I am trying to uploading chunks of 256 KB in Google Drive using REST API v3. I can successfully get the upload ID but when I use this upload ID to upload a chunk, I get a 400 Bad Request instead of 308. I am posting the code below. The method getUploadID() initiates a resumable upload session and the method putFileWithUploadID() should upload a chunk of the file but there seems to be a problem in it. I have written the code according to the official guide.
String mUploadID;

URL obj = new URL(url);
HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();
con.setRequestMethod("POST");
con.setDoInput(true);
con.setDoOutput(true);
con.setRequestProperty("Authorization", "Bearer " + token);
con.setRequestProperty("X-Upload-Content-Type", mimeType);
con.setRequestProperty("X-Upload-Content-Length", String.format(Locale.ENGLISH, "%d", fileContent.length()));

con.setRequestProperty("Content-Length", String.format(Locale.ENGLISH, "%d", body.getBytes().length));
OutputStream outputStream = con.getOutputStream();
outputStream.write(body.getBytes());
outputStream.close();
con.connect();
String location = con.getHeaderField("Location");
if (location.contains("upload_id")) {
String[] uploadParameters = location.split("upload_id");
upload_id = uploadParameters[1].replace("=", "");
}
} catch (Exception e) {
e.printStackTrace();
}
return upload_id;
}
private void putFileWithUploadID(Uri fileUri, String token, long range) {
java.io.File fileContent = new java.io.File(fileUri.getPath());
String fileName = fileContent.getName();
String contentLength = String.valueOf(fileContent.length());
String mimeType = "audio/mpeg";

}

con.setRequestProperty("Content-Range", "bytes " + chunkStart + "-" + (chunkStart + uploadedBytes - 1) + "/" + fileContent.length());
byte[] buffer = new byte[(int) uploadedBytes];
FileInputStream fileInputStream = new FileInputStream(fileContent);
fileInputStream.getChannel().position(chunkStart);
if (fileInputStream.read(buffer, 0, (int) uploadedBytes) == -1) {
break;
}
fileInputStream.close();
OutputStream outputStream = con.getOutputStream();
outputStream.write(buffer);
outputStream.close();
con.connect();
int responseCode = con.getResponseCode();
String rangeHeader = con.getHeaderField("Range");
if (rangeHeader!=null) {
chunkStart = Long.parseLong(rangeHeader.substring(rangeHeader.lastIndexOf("-") + 1, rangeHeader.length())) + 1;
}
} catch (Exception e) {
e.printStackTrace();
}
} while ((chunkStart+chunkSize)<fileContent.length());
}
Basically, 400: Bad Request means that a required field or parameter has not been provided, the value supplied is invalid, or the combination of provided fields is invalid.
This error can be thrown when trying to add a duplicate parent to a Drive item. It can also be thrown when trying to add a parent that would create a cycle in the directory graph.
You may also check this related SO post which suggested to properly use the Android-specific API to do resumable upload. See creating files.
I want to make a POST by using HttpURLConnection.
I am trying this in 2 ways, but I always get an excetion when doing: conn.getOutputStream();

The URL simply cannot be reached. Either the URL is wrong, or the DNS server couldn't resolve the hostname. Try a simple connect with a well-known URL to exclude one and other, e.g.
InputStream response = new URL("http://stackoverflow.com").openStream();
// Consume response.
Update as per the comments, you're required to use a proxy server for HTTP connections. You need to configure that in the Java side as well. Add the following lines before any attempt to connect to an URL.
System.setProperty("http.proxyHost", "proxy.example.com");
System.setProperty("http.proxyPort", "8080");
It suffices to do this only once during runtime.

Java guides - Networking and proxies
Without establishing the connection (which in this case requires 1 more step to be performed ie connect), transfer is not possible. connect() should be called after the connection is configured (ie after being done with the set***() on the connection).
What is missing is:
conn.connect();
