[英]HTTP 401 exception while using GET method of JIRA REST API from Java Code
I am trying to consume JIRA API with java code. 我正在尝试使用Java代码使用JIRA API。 It is giving me 401. This error states that
它给我401。此错误指出
HTTP Error 401 - Unauthorized: Access is denied due to invalid credentials.
But the link and credentials which I am using in the code are working perfectly fine with Firefox REST Client.It is driving me crazy. 但是我在代码中使用的链接和凭据与Firefox REST Client完美配合,这让我发疯。 Here is my code.
这是我的代码。
String url = "https://jira.atlassian.com/rest/api/1/search?jql=project=APS";
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
//Setting the Request Method header as GET
con.setRequestMethod("GET");
//Prepairing credentials
String cred= "ahmed.tausif@spmconsulting.net:spm12345678";
byte[] encoded = Base64.encodeBase64(cred.getBytes());
String credentials = new String(encoded);
//Setting the Authorization Header as 'Basic' with the given credentials
con.setRequestProperty ("Authorization", "Basic " + credentials);
//Setting the User-Agent header
con.setRequestProperty("User-Agent", USER_AGENT);
int responseCode = con.getResponseCode();
//reading the return
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream())
);
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
String result = response.toString();
I am getting the following exception 我收到以下异常

Hours spent on this cant figure it out. 花在这个上的时间无法弄清楚。
ps Also when I send a GET request through Firefox RESTClient the following box appears, clicking on it 5-7 times makes it disappear then I can see the result. ps另外,当我通过Firefox RESTClient发送GET请求时,将出现以下框,单击5-7次使其消失,然后我可以看到结果。
I tried your exact same code (with some very minor changes) and it worked perfectly. 我尝试了与您完全相同的代码(进行了一些非常小的更改),并且效果很好。 From this I can only assume:
由此我只能假设:
Try using 尝试使用
java.util.Base64.getEncoder().encode(cred.getBytes())
instead 代替
My whole code, for your reference: 我的完整代码,供您参考:
package hello;
import org.springframework.http.HttpHeaders;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Base64;
public class Application {
public static void main(String args[]) throws IOException {
String url = "https://my-jira-domain.atlassian.net/rest/api/2/issue/MOON-13";
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
//Setting the Request Method header as GET
con.setRequestMethod("GET");
//Prepairing credentials
String cred = "my@jira.com:mypassword";
byte[] encoded = Base64.getEncoder().encode(cred.getBytes());
String credentials = new String(encoded);
//Setting the Authorization Header as 'Basic' with the given credentials
con.setRequestProperty("Authorization", "Basic " + credentials);
//Setting the User-Agent header
con.setRequestProperty("User-Agent", HttpHeaders.USER_AGENT);
int responseCode = con.getResponseCode();
//reading the return
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream())
);
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
String result = response.toString();
}
}
