最近Webapi接口的开发刚刚进入尾声,随之而来的是让用户知道接口的详细参数信息,看过淘宝的接口文档,但网上没找到他的实现方式
虽然新建Webapi时C#也会给你一个帮助文档的Area,但是总觉得有些太复杂了,实用性值得商榷,于是对他做了些阉割,就有了自己的一个版本。
今天只完成了一些基本框架,具体细节有待进一步实现。
总体思路如下:
1:扩展HttpConfiguration的属性来加入自己的帮助文档生成器,
2:在每个Controller中添加该Controller的帮助信息
3:查看HTML时结合ApiDescription信息和2中添加的帮助信息来生成页面
以下为一些代码:
注册自定义帮助解析器:
public static class HelpPageConfigurationExtensions
{
/// <summary>
/// 添加Controller信息到文档生成器中
/// </summary>
/// <param name="config">The <see cref="HttpConfiguration"/>.</param>
/// <param name="sampleObjects">The sample objects.</param>
public static void SetSampleObjects(this System.Web.Http.HttpConfiguration config, ControllerDocumentModel controller)
{
config.GetHelpDocumentGenerator().Controllers.Add(controller);
}
/// <summary>
/// 获取已经注册进来的帮助信息
/// </summary>
/// <param name="config"></param>
/// <returns></returns>
public static List<ControllerDocumentModel> GetSampleObjects(this System.Web.Http.HttpConfiguration config)
{
return config.GetHelpDocumentGenerator().Controllers;
} /// <summary>
/// 在属性中添加文档生成器
/// </summary>
/// <param name="config">The <see cref="HttpConfiguration"/>.</param>
/// <returns>The help page sample generator.</returns>
public static ApiHelpDocumentGenerator GetHelpDocumentGenerator(this System.Web.Http.HttpConfiguration config)
{
return (ApiHelpDocumentGenerator)config.Properties.GetOrAdd(
typeof(ApiHelpDocumentGenerator),
k => new ApiHelpDocumentGenerator());
}
}
每个Controller都会实现一个虚方法,所以这里可以反射来统一调用,把每个Controller的帮助信息添加到生成器的列表中。
public class ApiHelpDocumentRegister
{
public static void Regist(System.Web.Http.HttpConfiguration config)
{
var asm = System.Reflection.Assembly.GetExecutingAssembly(); var controllerTypeList = asm.GetTypes().Where(x => x.BaseType == typeof(_BaseApiController)); foreach (var controllerType in controllerTypeList)
{
var controller = asm.CreateInstance(controllerType.FullName); var method = controllerType.GetMethod("CreateApiHelpDocument",
System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance); try
{
var result = method.Invoke(controller, null); config.SetSampleObjects(result as ControllerDocumentModel);
}
catch (NotImplementedException ex)
{
//未实现该方法
}
catch (Exception ex)
{
//其它异常
}
}
}
}
Controller自定义帮助内容
public class ControllerDocumentModel
{
public ControllerDocumentModel()
{
Actions = new List<ActionDocumentModel>();
}
/// <summary>
/// Controller名称
/// </summary>
public string ControllerName { get; set; }
/// <summary>
/// Controller说明
/// </summary>
public string ControllerSummary { get; set; }
/// <summary>
/// Action列表
/// </summary>
public List<ActionDocumentModel> Actions { get; set; }
}
Action自定义帮助内容
public class ActionDocumentModel
{
public ActionDocumentModel()
{
Params = new List<ParamDocumentModel>();
}
/// <summary>
/// Action名称
/// </summary>
public string ActionName { get; set; }
/// <summary>
/// Action说明
/// </summary>
public string ActionSummary { get; set; }
/// <summary>
/// Action参数列表
/// </summary>
public List<ParamDocumentModel> Params { get; set; }
/// <summary>
/// 返回值类型
/// </summary>
public Type ReturnValueType { get; set; }
/// <summary>
/// 返回值说明
/// </summary>
public string ReturnValueSummary { get; set; }
/// <summary>
/// 正常返回值示例
/// </summary>
public object ReturnValueSampleObject_Success { get; set; }
/// <summary>
/// 发生错误时的返回值示例
/// </summary>
public object ReturnValueSampleObject_Failed { get; set; }
}
参数自定义帮助:
public class ParamDocumentModel
{
/// <summary>
/// 参数名称
/// </summary>
public string ParamName { get; set; }
/// <summary>
/// 参数来源
/// </summary>
public ParameterBindings ParameterBinding { get; set; }
/// <summary>
/// 参数说明
/// </summary>
public string ParamSummary { get; set; }
/// <summary>
/// 参数类型
/// </summary>
public Type ParamType { get; set; }
/// <summary>
/// 参数示例数据
/// </summary>
public object ParamSampleObject { get; set; }
}
