通过更改以下代码使程序正常工作。与大多数情况下一样，使用
JSON库来
JSON像上面那样创建复合体是一个好习惯，而不是像大多数时候手动创建那样，手动创建复合体
JSON可能会带来很多麻烦。
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(); } }
