Java程序以获取JIRA中问题的自定义

本文介绍了Java程序以获取JIRA中问题的自定义/默认字段的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我已经开发了一个简单的Java程序来获取问题/用户故事的数据.我想获取特定问题的描述"字段.我已经使用GET方法获取响应,但是在连接JIRA时出现错误.

I have developed a simple java program to fetch the data of issues/user stories.I want to fetch 'description' field of a perticular issue. I have used GET method to get response but I'm getting errors while connecting to JIRA.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

public class JiraIssueDescription {

public static void main(String[] args) {

  try {

    URL url = new URL("https://****.atlassian.net/rest/agile/1.0/issue/41459");
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setRequestMethod("GET");
    conn.setRequestProperty("Accept", "application/json");
    conn.setRequestProperty("username", "***@abc.com");
    conn.setRequestProperty("password", "****");

    if (conn.getResponseCode() != 200) {
        throw new RuntimeException("Failed : HTTP error code : "
                + conn.getResponseCode());
    }

    BufferedReader br = new BufferedReader(new InputStreamReader(
        (conn.getInputStream())));

    String output;
    System.out.println("Output from Server .... \n");
    while ((output = br.readLine()) != null) {
        System.out.println(output);
    }

    conn.disconnect();

  } catch (MalformedURLException e) {

    e.printStackTrace();

  } catch (IOException e) {

    e.printStackTrace();

  }

}

}

运行项目时出现以下错误

When I run the project I get following error

java.net.UnknownHostException: ****.atlassian.net

任何人都可以帮助我解决错误.我需要实现OAuth吗?

Can anyone please help me with the errors. Do I need to implement OAuth ?

推荐答案

UnknownHostException似乎您的URL中有错字或.

UnknownHostException looks like you have a typo in your URL or are facing some proxy issues .

  1. 在浏览器中可以使用吗?它应该给你一些json作为响应.像这样: https://jira.atlassian.com/rest/api/2/问题/JSWCLOUD-11658

  1. Does it work in your Browser?It should give you some json in response. Like this:https://jira.atlassian.com/rest/api/2/issue/JSWCLOUD-11658

您还可以使用其他工具(例如curl)进行测试.它行得通吗?curl https://jira.atlassian.com/rest/api/2/issue/JSWCLOUD-11658

You could also test with other tools like curl. Does it work?curl https://jira.atlassian.com/rest/api/2/issue/JSWCLOUD-11658

Atlassian REST API提供了两种身份验证方法 ,基本身份验证和Oauth. 使用此方法创建有效的基本auth标头或尝试不带参数的请求./p>

Atlassian rest API provides two authentication methods, Basic auth and Oauth. Use this approach to create a valid basic auth header or try the request without parameters.

以下代码演示了其工作方式:

The following code demonstrates how it should work:

package stack48618849;

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

import org.junit.Test;

public class HowToReadFromAnURL {
    @Test
    public void readFromUrl() {
        try (InputStream in = getInputStreamFromUrl("https://jira.atlassian.com/rest/api/2/issue/JSWCLOUD-11658")) {
            System.out.println(convertInputStreamToString(in));
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    @Test(expected = RuntimeException.class)
    public void readFromUrlWithBasicAuth() {
        String user="aUser";
        String passwd="aPasswd";
        try (InputStream in = getInputStreamFromUrl("https://jira.atlassian.com/rest/api/2/issue/JSWCLOUD-11658",user,passwd)) {
            System.out.println(convertInputStreamToString(in));
        } catch (Exception e) {
            System.out.println("If basic auth is provided, it should be correct: "+e.getMessage());
            throw new RuntimeException(e);
        }
    }

    private InputStream getInputStreamFromUrl(String urlString,String user, String passwd) throws IOException {
        URL url = new URL(urlString);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("Accept", "application/json");
        String encoded = Base64.getEncoder().encodeToString((user+":"+passwd).getBytes(StandardCharsets.UTF_8));
        conn.setRequestProperty("Authorization", "Basic "+encoded);
        return conn.getInputStream();
    }

    private InputStream getInputStreamFromUrl(String urlString) throws IOException {
        URL url = new URL(urlString);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("Accept", "application/json");
        return conn.getInputStream();
    }

    private String convertInputStreamToString(InputStream inputStream) throws IOException {
        ByteArrayOutputStream result = new ByteArrayOutputStream();
        byte[] buffer = new byte[1024];
        int length;
        while ((length = inputStream.read(buffer)) != -1) {
            result.write(buffer, 0, length);
        }
        return result.toString("UTF-8");
    }
}

此打印:

{"expand":"renderedFields,names,schema,operations,editmeta,changelog,versionedRepresentations","id":"789521","self":"https://jira.atlassian.com/rest/api/2/issue/789521","key":"JSWCLOUD-11658","fields":{"customfield_18232":...
If basic auth is provided, it should be correct: Server returned HTTP response code: 401 for URL: https://jira.atlassian.com/rest/api/2/issue/JSWCLOUD-11658
