JIRA 使用神奇的JQL查询数据,很nice啊 !
  官网API:   https://docs.atlassian.com/jira/REST/latest/#d2e2344
  测试一下search:
/rest/api/2/search
request query parameters
parametervaluedescription
jql
string
a JQL query string
startAt
int
the index of the first issue to return (0-based)
maxResults
int
the maximum number of issues to return (defaults to 50). The maximum allowable value is dictated by the JIRA property 'jira.search.views.default.max'. If you specify a value that is higher than this number, your search results will be truncated.
validateQuery
boolean
Default:true
whether to validate the JQL query
fields
string
the list of fields to return for each issue. By default, all navigable fields are returned.
expand
string
A comma-separated list of the parameters to expand.
  其中jql 是一个JQL的query string。 
  测试代码:
string url = baseURL + "/search?jql=assignee=" +username +" and (status=1 or status=2)";
HttpWebRequest req = WebRequest.Create(url) as HttpWebRequest;
try
{
req.ContentType = "application/json";
req.Headers.Add("Authorization", "Basic " + m_authString);
using (HttpWebResponse resp = req.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(resp.GetResponseStream());
response = reader.ReadToEnd();
}
}
catch (Exception e)
{
response = e.Message;
m_errorMsg = e.Message;
return false;
}
  也可以直接装好以后,用url直接回车访问上述创建的链接,会直接得到数据信息到页面
