rest - Sonatype Nexus Rest API 401 未经授权

Question

我正在尝试使用 Rest API 从 java 的安全关系存储库中获取工件。我收到 401 Unauthorized 作为响应。

我需要做什么才能授权自己？

String url = "http://myNexus.com/service/local/artifact/maven/redirect?r=my-repo&g=my.group&a=my-artifact&v=LATEST";

HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(url);

HttpResponse response = null;

response = client.execute(request);

System.out.println("Response Code : "
       + response.getStatusLine().getStatusCode());

Answer 1

I would suggest to use the Nexus Client library rather than writing your own Java wrapper for the REST API. More details and links to examples are in the Nexus book.

Answer 2

我用java来模拟GET方法。第三个参数“auth”是基本的 http 身份验证示例。

http://en.wikipedia.org/wiki/BASE64

    public String sendGet(String url, String param, String auth) {
    String result = "";
    BufferedReader in = null;
    try {
        String urlName = url + "?" + param;
        URL realUrl = new URL(urlName);
        URLConnection conn = realUrl.openConnection();
        conn.setRequestProperty("accept", "*/*");
        conn.setRequestProperty("connection", "Keep-Alive");
        conn.setRequestProperty("user-agent",
                "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)");
        conn.setRequestProperty("Accept", "application/json");
        conn.addRequestProperty("Authorization", "Basic " + auth);
        conn.connect();
        in = new BufferedReader(
                new InputStreamReader(conn.getInputStream()));
        String line;
        while ((line = in.readLine()) != null) {
            result += line;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    finally {
        try {
            if (in != null) {
                in.close();
            }
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
    return result;
}
