Thanks for any help in advanced.
Im working on a a project that requires me to use the Anilist api v2, which uses graphQL
. I've tried and tried for a few days now, and even approached 2 lecturers in my university for help to no avail, none of them have worked with graphql before.
Code posted below, I used the HTTP POST
code from another stackoverflow question, and for some reason I keep getting response code 400
, which suggests to me some kind of syntax error. I've tried a bunch of formats for the code, but I haven't yet stumbled upon the right one, and since i'm pretty new to programming, I can't really understand the examples on github.
Any help is appreciated, Thanks.
private static void aniList() {
try {
CloseableHttpClient client = HttpClients.createDefault();
HttpPost httpPost = new HttpPost("https://graphql.anilist.co");
StringEntity entity = new StringEntity("\"query\": \"query { \n" +
" Media (id: 1, type: ANIME) { \n" +
" title {\n" +
" english\n" +
" }\n" +
" }\n" +
"}\", " +
"\"variables\": \"{}\"");
httpPost.setEntity(entity);
httpPost.setHeader("Accept", "application/json");
httpPost.addHeader("Content-type", "application/json");
CloseableHttpResponse response = client.execute(httpPost);
int statusCode = response.getStatusLine().getStatusCode();
assert (statusCode == 200) : "response status code = " + statusCode + ", it's meant to be 200";
System.out.println("statusCode = " + statusCode);
client.close();
System.out.println(response.toString());
} catch (Exception exp) {
System.out.println("exception TRIGGERED");
System.out.println(exp.getMessage());
}
}

try {
String json = "{\"query\":\"";
json += query;
json += "\"}";
json = json.replace("\n", " ").replace(" ", " ");
URL url = new URL(endpoint);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setConnectTimeout(5000);
conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
conn.addRequestProperty("Accept", "application/json");
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setRequestMethod("POST");
OutputStream os = conn.getOutputStream();
os.write(json.getBytes("UTF-8"));
os.close();
// read the response
InputStream in = new BufferedInputStream(conn.getInputStream());
String result = org.apache.commons.io.IOUtils.toString(in, "UTF-8");
in.close();
conn.disconnect();
return result;
} catch (Exception exp) {
System.out.println("exception TRIGGERED");
System.out.println(exp.getLocalizedMessage());
return "";
}
query example:
query {
Media (search: "naruto", type: ANIME) {
id
title {
english
romaji
native
}
}
}
This works well for me, in my question, I didn't properly format the json I think, I'd heard that json ignores excessive whitespace and newlines, but I guess not?
json = json.replace("\n", " ").replace(" ", " ");
does the job admirably.
