JIRA から生成したデータへアクセスする場合、一部のリソースへのアクセスにはユーザー認証が必要な場合があります (例：ログインが必要)。これには次の 3 つのオプションがあります。

1. To enable access to data without logging in, your JIRA administrator may specify the 'Browse' permission for Anyone.
2. You can provide the parameters os_username and os_password in the request URL (e.g. http://jira.atlassian.com/browse/TST-1?os_username=tester&os_password=tstpassword). The problem with this method is that it transmits your username and password across the wire in clear text, which may not be an option for some users.
3. You can provide the request parameter os_authType=basic (e.g. http://mycompany.com/anypage?os_authType=basic). This will force the server to issue a challenge for user credentials (i.e. a login prompt) via the basic http authentication protocol. If you are running over SSL, you still need to specify the os_authType=basic parameter if you require the user to authenticate.
