This might help you Got the program working by changing the above code as below. And it is a good practice to use a JSON library to create complex JSON like above other than manually creating it as most of the time, manual creation of a complex JSON may lead to lot of troubles. import org.json.JSONObject;
public void callingGraph(){
CloseableHttpClient client= null;
CloseableHttpResponse response= null;
client= HttpClients.createDefault();
HttpPost httpPost= new HttpPost("https://api.github.com/graphql");
httpPost.addHeader("Authorization","Bearer myToken");
httpPost.addHeader("Accept","application/json");
JSONObject jsonObj = new JSONObject();
jsonobj.put("query", "{repository(owner: \"wso2-extensions\", name: \"identity-inbound-auth-oauth\") { object(expression: \"83253ce50f189db30c54f13afa5d99021e2d7ece\") { ... on Commit { blame(path: \"components/org.wso2.carbon.identity.oauth.endpoint/src/main/java/org/wso2/carbon/identity/oauth/endpoint/authz/OAuth2AuthzEndpoint.java\") { ranges { startingLine, endingLine, age, commit { message url history(first: 2) { edges { node { message, url } } } author { name, email } } } } } } } }");
try {
StringEntity entity= new StringEntity(jsonObj.toString());
httpPost.setEntity(entity);
response= client.execute(httpPost);
}
catch(UnsupportedEncodingException e){
e.printStackTrace();
}
catch(ClientProtocolException e){
e.printStackTrace();
}
catch(IOException e){
e.printStackTrace();
}
try{
BufferedReader reader= new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String line= null;
StringBuilder builder= new StringBuilder();
while((line=reader.readLine())!= null){
builder.append(line);
}
System.out.println(builder.toString());
}
catch(Exception e){
e.printStackTrace();
}

how to access the github graphql API from java without running curl commands inside java

To fix the issue you can do The issue is pretty much that you have added an extra "query" word, it should be something like this: (...)
StringEntity entity= new StringEntity("{\"query\":\""+temp+"\"}");
import org.json.JSONObject; // New import
public void callingGraph(){
CloseableHttpClient client= null;
CloseableHttpResponse response= null;
client= HttpClients.createDefault();
HttpPost httpPost= new HttpPost("https://api.github.com/graphql");
httpPost.addHeader("Authorization","Bearer myToken");
httpPost.addHeader("Accept","application/json");
JSONObject jsonobj = new JSONObject();
jsonobj.put("query", "{repository(owner: \"wso2-extensions\", name: \"identity-inbound-auth-oauth\") { object(expression: \"83253ce50f189db30c54f13afa5d99021e2d7ece\") { ... on Commit { blame(path: \"components/org.wso2.carbon.identity.oauth.endpoint/src/main/java/org/wso2/carbon/identity/oauth/endpoint/authz/OAuth2AuthzEndpoint.java\") { ranges { startingLine, endingLine, age, commit { message url history(first: 2) { edges { node { message, url } } } author { name, email } } } } } } } }");
try {
StringEntity entity= new StringEntity(jsonobj.toString());
httpPost.setEntity(entity);
response= client.execute(httpPost);
}
catch(UnsupportedEncodingException e){
e.printStackTrace();
}
catch(ClientProtocolException e){
e.printStackTrace();
}
catch(IOException e){
e.printStackTrace();
}
try{
BufferedReader reader= new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String line= null;
StringBuilder builder= new StringBuilder();
while((line=reader.readLine())!= null){
builder.append(line);
}
System.out.println(builder.toString());
}
catch(Exception e){
e.printStackTrace();
}

How to write a resolver for a GraphQL subscription using graphql-java and graphql-java-servlet?

I think the issue was by ths following , Above stack trace comes when you try to use electron based GraphiQL.app which was not updated since Mar 22, 2018 (v.0.7.2). So, to fix an issue and see subscription working: <!-- Graph(i)QL tool: for development -->
<dependency>
<groupId>com.graphql-java-kickstart</groupId>
<artifactId>graphiql-spring-boot-starter</artifactId>
<version>5.4.1</version>
</dependency>
graphiql:
endpoint:
subscriptions: /graphql
subscription StockCodeSubscription {
stockQuotes {
dateTime
stockCode
stockPrice
stockPriceChange
}
}

Make a POST call to GraphQL API programmatically using Java
Tag : java , By : Kubla Khan

hope this fix your issue Below is a typical graphql endpoint for a java backend There are 2 basic flows here public Map<String, Object> graphqlGET(@RequestParam("query") String query,
@RequestParam(value = "operationName", required = false) String operationName,
@RequestParam("variables") String variablesJson) throws IOException {...
private Map<String, Object> executeGraphqlQuery(String operationName,
String query, Map<String, Object> variables) {
ExecutionInput executionInput = ExecutionInput.newExecutionInput()
.query(query)
.variables(variables)
.operationName(operationName)
.build();
return graphql.execute(executionInput).toSpecification();
}
val client = HttpClients.createDefault()
val httpPost = HttpPost(url)
val postParameters = ArrayList<NameValuePair>()
postParameters.add(BasicNameValuePair("query", "query as string"))
postParameters.add(BasicNameValuePair("variables", "variables json string"))
httpPost.entity = UrlEncodedFormEntity(postParameters, Charset.defaultCharset())
val response = client.execute(httpPost)
val ret = EntityUtils.toString(response.getEntity())

I wish did fix the issue. TLDR; This appears to be a bug. There's no way to bypass the limit applied when fetching a list of resources. Limiting responses like this is a common feature of public APIs -- if the response could include thousands or millions of results, it'll tie up a lot of server resources to fulfill it all at once. Allowing users to make those sort of queries is both costly and a potential security risk. query {
user(login:"armsp") {
repositories {
totalCount
}
repositories {
totalDiskUsage
}
}
}
query {
user(login:"armsp") {
repositories {
totalCount
totalDiskUsage
}
}
}
query {
user(login:"armsp"){
repositories{
totalCount
}
repositories{
nodes{
name
issues(states: OPEN){
totalCount
}
}
}
}
}
