可方便扩展的JIRA Rest Web API的封装调用

JIRA是一个缺陷跟踪管理系统，被广泛应用于缺陷跟踪、客户服务、需求收集、流程审批、任务跟踪、项目跟踪和敏捷管理等工作领域,当我们需要把第三方业务系统集成进来时，可以调用他的API。

JIRA本身的API非常强大，但它是一个底层的API体系，并不是一个易用的接口，如果要开发和拓展，所以需要我们二次包装。

jira官方为解决这个问题，推出了方便强大的java client library（目前只有java客户端库，没有.Net类库）

jira的Rest API  最新文档官网.

如果是编写java桌面或web应用，jira提供了更方便的方式（Client类库），JIRA REST Java Client is a Java library (usable from any JVM language) which allows to easily talk to any JIRA 4.2+ instance using new (and still evolving) REST API.

如果使用Client类库，可以方便应用各种现成的jira实体类（如项目、问题、备注、自定义字段......），不需要再重复造轮子，大幅提升效率。

首先，必须要了解JIRA api的接口结构，其中<resource-name>可以理解成api的方法，比如project，就是项目信息，user就是用户信息，issue就是问题信息....

http://hostname/rest/<api-name>/<api-version>/<resource-name>

JIRA's REST API is provided by a plugin that is anchored under the URI path component /rest/. Hence, if your JIRA site is running at:

还先要搞清楚jira api的 认证体系，摘自官网：

the first step in using the JIRA REST API is to authenticate a user account with your JIRA site. For the purposes of this tutorial we will use HTTP BASIC Authentication, but any authentication that works against JIRA will work against the REST API. This includes:

1. OAuth
2. HTTP Cookies
3. Trusted Applications
4. os_username/os_password query parameters

为方便使用，我们采用Basic Auth

Basic Auth headers

If you need to you may construct and send basic auth headers yourself. To do this you need to perform the following steps:

1. Build a string of the form username:password
2. Base64 encode the string
3. Supply an "Authorization" header with content "Basic " followed by the encoded string. For example, the string "fred:fred" encodes to "ZnJlZDpmcmVk" in base64, so you would make the request as follows.

一个curl的例子，注意红色字符串是对“username:password”的Base64编码
curl -D- -X GET -H "Authorization: Basic ZnJlZDpmcmVk" -H "Content-Type: application/json" "http://kelpie9:8081/rest/api/2/issue/QA-31"

搞清楚了Basic Auth，用C#进行代码实现，写了一个用于ASP.NET MVC的包装类，方便重复调用。

1、C#实现的API包装类

public class JiraApi
{
private string m_Username;
private string m_Password;

public JiraApi(string username, string password)
{
m_Username = username;
m_Password = password;
}

/// <summary>
/// 处理post请求，执行新建、编辑、删除等操作
/// </summary>
/// <param name="sData">json输入字符</param>
/// <param name="uri">api的具体地址，一般是baseurl + 业务处理资源关键字</param>
/// <returns>Jira返回的WebResponse输出</returns>
public string DoPost(string sData, string uri)
{
Uri address = new Uri(uri);
HttpWebRequest request;
//HttpWebResponse response1 = null;
StreamReader sr;
string returnXML = string.Empty;
if (address == null) { throw new ArgumentNullException("address"); }
try
{
request = WebRequest.Create(address) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
string base64Credentials = GetEncodedCredentials();
request.Headers.Add("Authorization", "Basic " + base64Credentials);
//request.Credentials = new NetworkCredential(sUsername, sPassword);
if (sData != null)
{
byte[] byteData = UTF8Encoding.UTF8.GetBytes(sData);
request.ContentLength = byteData.Length;
using (Stream postStream = request.GetRequestStream())
{
postStream.Write(byteData, 0, byteData.Length);
}
using (HttpWebResponse response1 = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response1.GetResponseStream());
string str = reader.ReadToEnd();
return str;

}
}
return "error";

}
catch (WebException wex)
{

if (wex.Response != null)
{

using (HttpWebResponse errorResponse = (HttpWebResponse)wex.Response)
{
try
{
string sError = string.Format("The server returned '{0}' with the status code {1} ({2:d}).",
errorResponse.StatusDescription, errorResponse.StatusCode,
errorResponse.StatusCode);
sr = new StreamReader(errorResponse.GetResponseStream(), Encoding.UTF8);
returnXML = sr.ReadToEnd();
return returnXML;

}
finally
{
if (errorResponse != null) errorResponse.Close();
}
}
}
else
{
//throw new Exception(wex.Message);
return wex.Message;

}
}
}

/// <summary>
/// 处理get请求，执行查询操作
/// </summary>
/// <param name="resource">输入的业务处理资源关键字，必填项</param>
/// <param name="argument">参数，用于获取具体查询操作，非必填项</param>
/// <param name="data">暂时没用处，非必填项</param>
/// <param name="method">默认为GET，非必填项</param>
/// <returns></returns>
public string DoQuery(
string resource,
string argument = null,
string data = null,
string method = "GET")
{
string url = string.Format("{0}{1}/", Config.BaseURL, resource.ToString());

if (argument != null)
{
url = string.Format("{0}{1}/", url, argument);
}

HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.ContentType = "application/json";
request.Method = method;

if (data != null)
{
using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
writer.Write(data);
}
}

string base64Credentials = GetEncodedCredentials();
request.Headers.Add("Authorization", "Basic " + base64Credentials);

HttpWebResponse response = request.GetResponse() as HttpWebResponse;

string result = string.Empty;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
result = reader.ReadToEnd();
}

return result;

}

private string GetEncodedCredentials()
{
string mergedCredentials = string.Format("{0}:{1}", m_Username, m_Password);
byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(mergedCredentials);
return Convert.ToBase64String(byteCredentials);
}
}

调用方法：查询Get

/// <summary>
/// 查询jira的项目情况
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void Page_Load(object sender, EventArgs e)
{
JiraApi manager = new JiraApi(Config.User, Config.Password);
Response.Write(manager.DoQuery("project"));
}

调用方法：提交Post

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
JiraApi api = new JiraApi(Config.User, Config.Password);
//对问题添加备注
SubmitComment(api, Request.QueryString["issue"], Request.QueryString["comment"]);
}
}
/// <summary>
/// 添加问题的备注
/// </summary>
/// <param name="jm">JiraApi实例</param>
/// <param name="issue">问题的关键字，比如SomeIssue-18</param>
/// <param name="comment">备注的内容</param>
private void SubmitComment(JiraApi api, string issue, string comment)
{
string sData = string.Format("{\"body\": \"{0}\"}", comment);
string uri = Config.BaseURL + string.Format("issue/{0}/comment", issue);
Response.Write(api.DoPost(sData, uri));
}
