HttpsURLConnection 400 Bad Request error occured

I need to convert below Swift code to Java.
Swift code works.
But, Java code is not worked.
HttpsURLConnection has failed.
responseCode: 400 (HttpsURLConnection.getResponseCode())
message2: Bad Request (HttpsURLConnection.getResponseMessage())
How can I solve 400 Bad Request error.
In Swift(It worked)
func sendNotification(token: String, message: String) {
//Firebase CloudMessaging serverkey
var firebaseServerKey = "AAAAA6qLps4:APA91bE7szGAgp3qYGOJsrSsrM1InhIgf5Fq1xxxxxx"
let url = URL(string: "https://fcm.googleapis.com/fcm/send")!
var request = URLRequest(url: url)
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("key=\(firebaseServerKey)", forHTTPHeaderField: "Authorization")
request.httpMethod = "POST"
request.httpBody = "{\"to\":\"\(token)\",\"notification\":{\"body\":\"\(message)\",\"badge\":\"1\"}}".data(using: .utf8)
}
I wrote in JAVA(not worked)
private void sendNotification(String token, String message) {
//Firebase CloudMessaging serverkey
var firebaseServerKey = "AAAAA6qLps4:APA91bE7szGAgp3qYGOJsrSsrM1InhIgf5Fq1xxxxxx"
try {
URL url = new URL("https://fcm.googleapis.com/fcm/send");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Authorization", "key="+firebaseServerKey);
String str = "{\"to\": " + token + ", \"notification\": { \"body\": " + message + ", \"badge\": \"1\"}}";
byte[] outputInBytes = str.getBytes("UTF-8");
OutputStream os = conn.getOutputStream();
os.write(outputInBytes);
os.close();
int responseCode = conn.getResponseCode(); // responseCode: 400
if (responseCode == HttpsURLConnection.HTTP_OK) {
Log.d("Success", String.valueOf(responseCode));
} else {
String code = String.valueOf(responseCode);
String message2 = conn.getResponseMessage(); // message2: Bad Request
Log.d("Fail", String.valueOf(responseCode));
Log.d("Fail2", conn.getResponseMessage());
}
}

Your JSON request body is incorrect. It produce {"to": zxc} which is an invalid json. Change it to
String str = "{\"to\": \"" + token + "\", \"notification\": { \"body\": \"" +
message + "\", \"badge\": \"1\"}}";

I'd like to send list to php file and save list to mysqli

Hi i'm trying to send course list which has more than 2,000 course info to mysqli through php file. but ! whenever i try to send list, it doesn't send it to server.
so can you help me to solve this problem..? :(
First, java source
public static void sendCourseInfoToDB(List<Subject> subjects, String url) {
try {
// url is my *.php file
URL target = new URL(url);
HttpURLConnection con = (HttpURLConnection) target.openConnection();
con.setRequestMethod("POST");
con.setDoOutput(true);
con.setDoInput(true);
con.setUseCaches(false);
con.setRequestProperty("Content-Type", "text/html; charset = utf-8");
DataOutputStream out = new DataOutputStream(con.getOutputStream());
int len = subjects.size();
for (int i = 0; i < len; ++i) {
//String t = subjects.get(i).toString();
out.writeBytes(subjects.get(i).toString());
out.flush();
}
out.flush();
out.close();
int responseCode = con.getResponseCode();
System.out.println("Post rqeust to Url : " + url);
System.out.println("Post Params : " + subjects.get(0).toString());
System.out.println("Resoponse Code : " + Integer.toString(responseCode));
con.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
}
Subject class overrides toString. return-statement used parameter is encoded UTF-8
like this :
courseCode = 12156&courseName = %EC%8B%A0%EC%86%8C%EC%9E%AC%EA%B3%B5%ED%95%99%EB%B6%80&subjectName = %EC%A2%85%ED%95%A9%EA%B3%BC%EC%A0%9C%EC%84%A4%EA%B3%841&kindOfSubject = %EC%A0%84%EA%B3%B5&score = 2
and php file
<?php
header("Content-Type : text/html; charset = utf-8");
$mysqli = new mysqli("localhost", "user", "password", "db");
if($mysqli->mysqli_errno) {
print $mysqli_error;
exit();
}
$courseCode = $_POST["courseCode"];
$courseName = $_POST["courseName"];
$subjectName = $_POST["subjectName"];
$kindOfSubject = $_POST["kindOfSubject"];
$score = $_POST["score"];
$mysqli->query("INSERT INTO COURSE VALUES('$courseCode', '$courseName', '$subjectName', '$kindOfSubject', '$score')");
$response = $courseCode;
echo $response;
?>
should i call 'sendCourseInfoToDB function every time when i send course info to DB ? i dont know what is wrong.. help me crazy coding people~!~

JSONException: A JSONObject text must begin with '{' at character 1 error in HTTPS POST response

I am trying to POST HTTPS request to one of the client's server. In turn the response which is returned back from the server is missing "{" from the JSON response.
When the client is testing they are receiving proper response.
Can you please help me out on debugging whats an issue with the code content. The same issue persist of missing "<" character in
XML response while changing the header to "Accept", "application/xml".

My guess is that the webservice expects the parameters UID and KEY to be passed as JSON (or XML), not application/x-www-form-urlencoded.

Unable to set Authorization header of HttpsURLConnection

I'm trying to set the OAuth Authorization header of a HttpsURLConnection object and below is the java code for that
String url1 = "/data/ServiceAccount?schema=1.0&form=json&byBillingAccountId={EQUALS,xyz#pqr.edu}";
String url = "https://secure.api.abc.net/data/ServiceAccount?schema=1.0&byBillingAccountId={EQUALS,xyz#pqr.edu}";
String header = OAuthClient.prepareURLWithOAuthSignature(url1);
HttpsURLConnection con = null;
try {
URL obj = new URL(url);
con = (HttpsURLConnection) obj.openConnection();
con.setRequestMethod("GET");
con.setRequestProperty("Authorization", "OAuth " + header);
System.out.println("Request properties = " + con.getRequestProperty("Authorization"));
int responseCode = con.getResponseCode();
System.out.println("Response Code = " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
con.disconnect();
//print result
System.out.println("Response = " + response.toString());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if(con!=null) con.disconnect();
}
And below is the code for prepareURLWithOAuthSignature
public String prepareURLWithOAuthSignature(String url)
{
String signature = null;
setOAuthParameters();
setOAuthQParams();
try
{
httpURL = URLEncoder.encode(baseURL+url, "UTF-8");
signature = OAuthSignatureService.getSignature(httpURL, URLEncoder.encode(URLEncodedUtils.format(qparams, "UTF-8"), "UTF-8"), consumer_secret);
OAuthParameters.put("oauth_signature", signature);
} catch (Exception e) {
e.printStackTrace();
}
return getOAuthAuthorizationHeader();
}
public String getOAuthAuthorizationHeader()
{
String OAuthHeader = "oauth_consumer_key=\"" + OAuthParameters.get("oauth_consumer_key") + "\"" +
",oauth_signature_method=\"" + OAuthParameters.get("oauth_signature_method") + "\"" +
",oauth_timestamp=\"" + OAuthParameters.get("oauth_timestamp") + "\"" +
",oauth_nonce=\"" + OAuthParameters.get("oauth_nonce") + "\"" +
",oauth_version=\"" + OAuthParameters.get("oauth_version") + "\"" +
",oauth_signature=\"" + OAuthParameters.get("oauth_signature") + "\"";
byte[] authEncBytes = Base64.encodeBase64(OAuthHeader.getBytes());
String authStringEnc = new String(authEncBytes);
return authStringEnc;
}
The problem is that
1) while I'm printing the con.getRequestProperty("Authorization") I'm getting a null value which means the Authorization header is not set
2) The final response I'm getting from the server is 403
Any idea what's going wrong here?

I know this might not be an answer but looks like this issue was submitted as a bug to sun and here is the relevant part of the reply.
This behavior is intentional in order to prevent a security hole that
getRequestProperty() opened. setRequestProperty("Authorization")
should still work, you just won't be able to proof the results via
getRequestProperty().
For the original forum post, please see: http://www.coderanch.com/t/205485/sockets/java/setRequestProperty-authorization-JDK
I would not be able to advice why you're getting a 403 but try adding the "Content-Type" request header to your connection and see if it makes any difference. Until I added that header in my code, I was getting a 404 back from the Spring Security module.

Sugar get_entry_list returns "Invalid Session ID" when querying Meetings for a specific user

I try to query Sugar through its REST API using Java for entries in Meetings module for a specific user, namely the one who is logged in currently.
I am trying this a few days already while googling around for asolution.
I made a login() call, where I got a session ID, than I make a call to get_user_id(). With the returned user ID I try to query the Meetings module by using get_entry_list().
To get the Meetings assigned to the UserID it works with following query string, where mUserId holds the returned user id of get_user_id():
queryString = "meetings.assigned_user_id='"+mUserId+"'";
But I not only want to get the meetings, where a user is assigned to, but all Meetings where he participates. For that I try a subquery on meetings_users table in my query.
Here is a query strings I tried, which os working on MySQL prompt. But when I try this over REST, it returns "Invalid Session ID":
queryString = "meetings.id IN ( SELECT meetings_users.meeting_id FROM meetings_users WHERE meetings_users.user_id = '"+mUserId+"' )";
Does anyone have a hint on this? Which conditions lead to an "Invalid Session ID" at all?
What also does not work e.g. is appending "and deleted = '0'" to the first stated query:
queryString = "meetings.assigned_user_id='"+mUserId+"' and deleted = '0'";
also fails.
As requested here is the full code example, platform is Android, API Level 8:
private JSONArray getEntryList(String moduleName,
String selectFields[], String queryString, String orderBy, int max_results) throws JSONException, IOException, KeyManagementException, NoSuchAlgorithmException
{
JSONArray jsoSub = new JSONArray();
if (selectFields.length > 0)
{
for (int i = 0; i < selectFields.length; i++)
{
jsoSub.put(selectFields[i]);
}
}
// get_entry_list expects parameters to be ordered, JSONObject does
// not provide this, so I built my JSON String on my own
String sessionIDPrefix = "{\"session\":\""+ mSessionId+ "\"," +
"\"modulename\":\""+ moduleName+ "\"," +
"\"query\":\""+ queryString + "\"," +
"\"order_by\":\""+ orderBy + "\"," +
"\"offset\":\""+ mNextOffset+ "\"," +
"\"select_fields\":["+ jsoSub.toString().substring(
1, jsoSub.toString().length()-2)+ "\"],"+
"\"max_results\":\""+ 20 + "\"}";
String restData = sessionIDPrefix;
Log.d(TAG, restData);
String data = null;
String baseurl = mUrl + REST_URI_APPEND;

}
int response = 0;

try {

responseMessage = conn.getResponseMessage();
} catch (IOException e) {
conn.disconnect();
throw new IOException(mContext.getText(R.string.error_resp_io).toString());
}
Log.d(TAG, "Exception Response "+ response);
if (response != 200) {
conn.disconnect();
throw new IOException(mContext.getText(R.string.error_http).toString()
+ "\n" + response + " " + responseMessage);
}
StringBuilder sb = null;
try {
BufferedReader rd = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
sb = new StringBuilder();
String line;
while ((line = rd.readLine()) != null) {
Log.d(TAG,"line " + line);

}
conn.disconnect();
if (sb.toString() == null)
{
throw new IOException(mContext.getText(R.string.error_resp_empty).toString());
}
return sb.toString();
}
Calling the code above:
if (login() != OK)
return null;
mResultCount = -1;
mNextOffset = 0;
mUserId = getUserId();
String fields[] = new String [] {
"id",
"name",
"description",
"location",
"date_start",
"date_end",
"status",
"type",
"reminder_time",
"parent_type",
"parent_id",
"deleted",
"date_modified"
};
String queryString = null;
if (syncAllUsers)
queryString = "";
else
{
queryString = "meetings.assigned_user_id = 'seed_sarah_id' and meetings.deleted = '0'";
//queryString = "meetings.id IN ( SELECT meeting_id FROM meetings_users WHERE user_id ='"+mUserId+"'";
}
entryList.clear();
while (mResultCount != 0)
{
if (!seamless_login())
return null;
JSONArray serverEntryList = getEntryList(
"Meetings", fields, queryString, "date_start", 0);
//... do sth with data
}
totalContactsResults += mResultCount;
}
logout();
login() returns valid session id, and getUserId() returns right id. The whole code is already working for fetching contacts, and also working for a simple query as stated above.
Thanks in advance
Marc

After further testing, I realized, that whitespaces in the query string are the problem. They lead to an URL containing whitespace. To avoid that some kind of URL encoding has to be done.
I had not success in encoding the whole URL in my httpPost methods (seems not to be necessary). But replacing spaces with '+' in the query string works for me:
queryString = "meetings.id+IN+(SELECT+meetings_users.meeting_id+FROM meetings_users+WHERE+meetings_users.user_id='"+mUserId+"')";
If anyone has a more elegant method of doing this, please let me know.

You would probably be better off using the get_relationships web service call.
SugarRest.call('get_relationships', [SugarRest.session, 'Users', SugarRest.user_id, 'meetings', '', ['name'], 0, ''])
That should be all you need. In the parameter after 'meetings' you can also pass in an additional filter.
