Question

下面是我使用的代码，不确定我是否做错了什么并且卡在这里......

try {// Object jsonMessage = arg0.getMessage（）。getPayload（）;

        URL url = new URL("https://jira.mycomp.com/rest/api/latest/issue");

        HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();

        BASE64Encoder enc = new sun.misc.BASE64Encoder();
        String userpassword = "uname" + ":" + "pwd";
        String encodedAuthorization = enc.encode(userpassword.getBytes());
        conn.setDoOutput(true);
        conn.setDoInput(true);
        conn.setRequestProperty("Authorization", "Basic " + encodedAuthorization);
        //conn.setRequestProperty("Content-Type", "application/json;charset=UTF-8");

        conn.setRequestMethod("GET");

        OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
        wr.write("JIRA-ID");
        wr.flush();

        StringBuilder sb = new StringBuilder();
        int HttpResult = conn.getResponseCode();
        if (HttpResult == HttpsURLConnection.HTTP_OK) {
            BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(), "utf-8"));
            String line = null;
            while ((line = br.readLine()) != null) {
                sb.append(line + "\n");
            }
            br.close();
            System.out.println("" + sb.toString());
        } else {
            System.out.println(conn.getResponseMessage());
        }
    }catch(IOException e){
        e.printStackTrace();
    }
    catch(Exception e){
        e.printStackTrace();
    }
}

并获得以下异常

java.net.ConnectException：拒绝连接：连接 at java.net.DualStackPlainSocketImpl.connect0（Native Method）在java.net.DualStackPlainSocketImpl.socketConnect（DualStackPlainSocketImpl.java:79）在java.net.AbstractPlainSocketImpl.doConnect（AbstractPlainSocketImpl.java:350） at java.net.AbstractPlainSocketImpl.connectToAddress（AbstractPlainSocketImpl.java:206）在java.net.AbstractPlainSocketImpl.connect（AbstractPlainSocketImpl.java:188）在java.net.PlainSocketImpl.connect（PlainSocketImpl.java:172）在java.net.SocksSocketImpl.connect（SocksSocketImpl.java:392）在java.net.Socket.connect（Socket.java:589） at sun.security.ssl.SSLSocketImpl.connect（SSLSocketImpl.java:668） at sun.security.ssl.BaseSSLSocketImpl.connect（BaseSSLSocketImpl.java:173）在sun.net.NetworkClient.doConnect（NetworkClient.java:180）在sun.net.www.http.HttpClient.openServer（HttpClient.java:432）在sun.net.www.http.HttpClient.openServer（HttpClient.java:527）在sun.net.www.protocol.https.HttpsClient。（HttpsClient.java:264）在sun.net.www.protocol.https.HttpsClient.New（HttpsClient.java:367） at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.getNewHttpClient（AbstractDelegateHttpsURLConnection.java:191）在sun.net.www.protocol.http.HttpURLConnection.plainConnect0（HttpURLConnection.java:1105） at sun.net.www.protocol.http.HttpURLConnection.plainConnect（HttpURLConnection.java:999） at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect（AbstractDelegateHttpsURLConnection.java:177） at sun.net.www.protocol.http.HttpURLConnection.getOutputStream0（HttpURLConnection.java:1283） at sun.net.www.protocol.http.HttpURLConnection.getOutputStream（HttpURLConnection.java:1258） at sun.net.www.protocol.https.HttpsURLConnectionImpl.getOutputStream（HttpsURLConnectionImpl.java:250）

您可以使用HttpURLConnection Spring创建自己的RestTemplate客户端来调用REST，而不是使用JIRA REST APIs。。您可以从StackOverflow上的另一个答案中引用我的示例代码。

Java Program to fetch custom/default fields of issues in JIRA

希望这有助于通过完全不同的方法回答您的问题。请向我提供您对我的代码的任何反馈（我希望进一步发展）。
