使用Java调用Confluence的REST API

API接口说明文档传送门

Confluence的REST API访问一样采用http访问的形式，但最主要的是接口的鉴权，本文使用的是用户名+密码的鉴权方式。当然Confluence还提供令牌的鉴权方式，只是需要自己通过界面申请。闲话少叙，直接放代码

public class Test {
    public static void main(String[] args) throws UnsupportedEncodingException {
        //用户名
        String name = "xxxxxx";
        //密码
        String password = "xxxxxxx";
        String authString = name + ":" + password;
        byte[] authEncBytes = Base64.encodeBase64(authString.getBytes("utf-8"));
        String authStringEnc = new String(authEncBytes);
        //注意加空格
        System.out.println("Basic " + authStringEnc);
    }
}

使用PostMan测试

public class Test {
    private static String path = "xxxxxxxxxxx";

    
    public static void main(String[] args) throws UnsupportedEncodingException {
        //用户名
        String name = "xxxxxxx";
        //密码
        String password = "xxxxxxxx";
        String authString = name + ":" + password;
        byte[] authEncBytes = Base64.encodeBase64(authString.getBytes("utf-8"));
        String authStringEnc = new String(authEncBytes);
        //注意加空格
        System.out.println("Basic " + authStringEnc);
        BufferedReader in = null;
        StringBuilder result = new StringBuilder();
        try {
            URL realUrl = new URL(path);
            URLConnection connection = realUrl.openConnection();
            connection.setRequestProperty("Content-Type", "application/json; charset=utf-8");
            connection.setRequestProperty("Accept", "application/json; charset=utf-8");
            connection.setRequestProperty("Authorization", "Basic " + authStringEnc);
            connection.connect();
            in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"));
            String line;
            while ((line = in.readLine()) != null) {
                result.append(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (in != null) {
                    in.close();
                }
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }
        System.out.println(result.toString());
    }
}

上述代码采用的是Get提交方式，如果REST API需要Post的提交方式，可将代码中URL连接改成Post方式。当然，更推荐使用HttpClient或OkHttp等轮子。
