JIRA REST API returns HTTP error code : 404

[shital chande]

Hi, I'm trying to use the JIRA rest API to get the issue is moved on one status to another, however, for all queries that I tried it returns 404 status.

An example http://localhost:8080/rest/attach-cat/1.0/attachments/get?issueKey=" +issue, however, it returns 404.

And Jira is 7.13.0

Thank you,

Tomas Gustavsson,

, for replying me. and now following link is working:

String urlCAL="http://192.168.1.236:8082/rest/api/2/attachment/"+issue;

but still, the same error has occurred. can you tell me please what can i change for following code to give me a list of attached files ?:

==========================

try
{
String authString = "vpsvalidator:8c5ydjGL0S8ZiZsODG2JetNqn";
String authStringEnc = Base64.getEncoder().encodeToString(authString.getBytes("utf-8"));
URL url = new URL(urlCAL);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty("Authorization", "Basic " + authStringEnc);
if (conn.getResponseCode() != 200)
{
throw new RuntimeException("Failed : HTTP error code : "+ conn.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader((conn.getInputStream())));
String output = org.apache.commons.io.IOUtils.toString(br);
Pattern folderpattern = Pattern.compile("\"id\":(.+?),\"name\":\"(.+?)\",\"attachments\":(.+?)]") ;
Matcher foldermatch = folderpattern.matcher(output);
message1 = message1+ output;
while(foldermatch.find())
{
String attachmentsID = foldermatch.group(1);
String attachmentsFolders = foldermatch.group(2);
String attachmentsDetails = foldermatch.group(3);
if(attachmentsFolders.contains(requiredValue))
{
String folderFiles1 =attachmentsDetails.replace("{","");
String folderFiles2 =folderFiles1.replace("[","");
String folderFiles3 =folderFiles2.replaceAll("\"","");
folderFiles =folderFiles3.replace("ids:","");
message1= message1+folderFiles;
}
}
}
catch (Exception e)
{
e.printStackTrace();
throw new InvalidInputException(e+"Unable to Find the Selected folder"+message1+"---"+folderFiles+"==="+requiredValue);
}

To get the Attachments, you need to have the attachments id. ex like below. 
https://jira/rest/api/2/attachment/139053

so first you need to find the issue and see if i holds any attachments, and then get the attachments Id, then you can use that to request it.

Thanks, Tomas for understanding my concept and I want to use the GET method to find the issue and see if I hold any attachments, and then get the attachments Id then what I need to do change the below code : 

String authString = "vpsvalidator:8c5ydjGL0S8ZiZsODG2JetNqn";
String authStringEnc = Base64.getEncoder().encodeToString(authString.getBytes("utf-8"));
URL url = new URL(urlCAL);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty("Authorization", "Basic " + authStringEnc);
if (conn.getResponseCode() != 200)
{
throw new RuntimeException("Failed : HTTP error code : "+ conn.getResponseCode());
}
br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
message1 = message1+ org.apache.commons.io.IOUtils.toString(br);
folderpattern = Pattern.compile("\"id\":(.+?),\"name\":\"(.+?)\",\"attachments\":(.+?)]");
Matcher foldermatch = folderpattern.matcher(message1);
while(foldermatch.find())
{
String attachmentsID = foldermatch.group(1);
String attachmentsFolders = foldermatch.group(2);
String attachmentsDetails = foldermatch.group(3);
if(attachmentsFolders.contains(requiredValue))
{
String folderFiles1 =attachmentsDetails.replace("{","");
String folderFiles2 =folderFiles1.replace("[","");
String folderFiles3 =folderFiles2.replaceAll("\"","");
folderFiles =folderFiles3.replace("ids:","");
message1= message1+folderFiles;
}
}
}
catch (Exception e) 
{
e.printStackTrace();
throw new InvalidInputException(e+"--Unable to Find the Selected folder");
} 

can you suggest to me?
