JRJC Java客户端问题

Question

我正在尝试连接到 JIRA 并使用 JIRA 查询语言 (JQL) 来查找最新项目。我得到了这个示例，并尝试连接 URL https://issues.apache.org/jira/rest/api/latest/search 和我的凭据，但出现错误。大多数示例将localhost 显示为连接URL。我使用的凭据是我的登录凭据（适用于网站）。

这是错误堆栈：

 Exception in thread "main" com.atlassian.jira.rest.client.RestClientException: org.codehaus.jettison.json.JSONException: A JSONObject text must begin with '{' at character 1 of <?xml version="1.0" encoding="UTF-8" standalone="yes"?><status><status-code>404</status-code><message>null for uri: https://issues.apache.org/jira/rest/api/latest/search/rest/api/latest/user?username=rabaner&amp;expand=groups</message></status>

问题在于 URL 不正确。应该是：

https://issues.apache.org/jira/rest/api/latest/user?username=rabaner&expand=groups

修复我收到的：

{"self":"https://issues.apache.org/jira/rest/api/2/user?username=rabaner","key":"rabaner","name":"rabaner","emailAddress":"ranjanbanerjee5 at gmail dot com","avatarUrls":{"48x48":"https://issues.apache.org/jira/secure/useravatar?avatarId=10452","24x24":"https://issues.apache.org/jira/secure/useravatar?size=small&avatarId=10452","16x16":"https://issues.apache.org/jira/secure/useravatar?size=xsmall&avatarId=10452","32x32":"https://issues.apache.org/jira/secure/useravatar?size=medium&avatarId=10452"},"displayName":"Ranjan Banerjee","active":true,"timeZone":"Etc/UTC","groups":{"size":1,"items":[]},"expand":"groups"}
