Java Http request on api.stackexchange with json response
- by taoder
I'm trying to use the api-stackexchange with java but when I do the request and try to parse the response with a json parser I have an error.
public ArrayList<Question> readJsonStream(InputStream in) throws IOException {
JsonReader reader = new JsonReader(new InputStreamReader(in, "UTF-8"));
reader.setLenient(true);
try {
System.out.println(reader.nextString()); // ? special character
return readItem(reader);
} finally {
reader.close();
}
}
public ArrayList<Question> readItem(JsonReader reader) throws IOException {
ArrayList<Question> questions = new ArrayList<Question>();
reader.beginObject();
while (reader.hasNext()) {
System.out.println("here");//not print the error is before
String name = reader.nextName();
if (name.equals("items")) {
questions = readQuestionsArray(reader);
}
}
reader.endObject();
return questions;
}
public final static void main(String[] args) throws Exception {
URIBuilder builder = new URIBuilder();
builder.setScheme("http").setHost("api.stackexchange.com").setPath("/2.0/search")
.setParameter("site", "stackoverflow")
.setParameter("intitle" ,"workaround")
.setParameter("tagged","javascript");
URI uri = builder.build();
String surl = fixEncoding(uri.toString()+"&filter=!)QWRa9I-CAn0PqgUwq7)DVTM");
System.out.println(surl);
Test t = new Test();
try {
URL url = new URL(surl);
t.readJsonStream(url.openStream());
} catch (IOException e) {
e.printStackTrace();
}
}
And the error is:
com.google.gson.stream.MalformedJsonException: Expected literal value
at line 1 column 19
Here is an example of the Json :
{
"items": [
{
"question_id": 10842231,
"score": 0,
"title": "How to push oath token to LocalStorage or LocalSession and listen to the Storage Event? (SoundCloud Php/JS bug workaround)",
"tags": [
"javascript",
"javascript-events",
"local-storage",
"soundcloud"
],
"answers": [
{
"question_id": 10842231,
"answer_id": 10857488,
"score": 0,
"is_accepted": false
}
],
"link": "http://stackoverflow.com/questions/10842231/how-to-push-oath-token-to-localstorage-or-localsession-and-listen-to-the-storage",
"is_answered": false
},...
So what's the problem? Is the Json really malformed? Or did I do something not right?
Thanks, Anthony
