1、WebApiConfig全局处理
///
/// WebApiConfig
/// 路由基础配置。
///
///
/// 修改记录
///
/// 2016.11.01 版本：2.0 宋彪 对日期格式进行统一处理。
/// 2016.10.30 版本：2.0 宋彪 解决json序列化时的循环引用问题。
/// 2016.10.28 版本：2.0 宋彪 回传响应格式 $format 支持。
/// 2016.09.01 版本：1.0 宋彪 创建。
///
/// 版本：1.0
///
///
/// 宋彪
/// 2016.09.01
///
///
public static class WebApiConfig
{
///
/// 注册全局配置服务
///
///
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
//强制https访问
//config.Filters.Add(new ForceHttpsAttribute());
// 统一回传格式
config.Filters.Add(new ApiResultAttribute());
// 发生异常时处理
config.Filters.Add(new ApiErrorHandleAttribute());
// ToKen身份验证过滤器 更方便 不需要在这里了 具有改标签的就会自动检查
//config.Filters.Add(new ApiAuthFilterAttribute());
// 解决json序列化时的循环引用问题
config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
//对日期格式进行统一处理
config.Formatters.JsonFormatter.SerializerSettings.Converters.Add(
new IsoDateTimeConverter()
{
DateTimeFormat = "yyyy-MM-dd hh:mm:ss"
}
);
// Web API routes 路由
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
// 干掉XML序列化器
//config.Formatters.Remove(config.Formatters.XmlFormatter);
//在请求的Url加上 ?$format=xml，便可以指定响应格式
config.Formatters.XmlFormatter.AddQueryStringMapping("$format", "xml", "application/xml");
config.Formatters.JsonFormatter.AddQueryStringMapping("$format", "json", "application/json");
}
}
2、身份验证过滤器
using DotNet.Business;
using DotNet.Utilities;
using DotNet.Tracking.API.Common;
///
/// ApiAuthFilterAttribute
/// 身份验证过滤器,具有ApiAuthFilterAttribute标签属性的方法会自动检查
///
///
/// 修改纪录
///
/// 2016-10-11 版本：1.0 SongBiao 创建文件。
///
///
/// SongBiao
/// 2016-10-11
///
///
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
public class ApiAuthFilterAttribute : AuthorizationFilterAttribute
{
///
/// 未授权时的提示信息
///
private const string UnauthorizedMessage = "请求未授权，拒绝访问。";
///
/// 权限进入
///
///
public override void OnAuthorization(HttpActionContext actionContext)
{
base.OnAuthorization(actionContext);
// 允许匿名访问
if (actionContext.ActionDescriptor.GetCustomAttributes().Count > 0)
{
return;
}
string systemCode = APIOperateContext.Current.SystemCode;
string permissionCode = APIOperateContext.Current.PermissionCode;
string appKey = APIOperateContext.Current.AppKey;
string appSecret = APIOperateContext.Current.AppSecret;
if (string.IsNullOrWhiteSpace(appKey) || string.IsNullOrWhiteSpace(appSecret))
{
//未验证（登录）的用户, 而且是非匿名访问，则转向登录页面
//actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized);
//actionContext.Response.Content = new StringContent("Unauthorized
", Encoding.UTF8, "text/html");
var response = actionContext.Response= actionContext.Response?? new HttpResponseMessage();
response.StatusCode = HttpStatusCode.Unauthorized;
BaseResult result = new BaseResult
{
Status = false,
StatusMessage = UnauthorizedMessage
};
response.Content = new StringContent(result.ToJson(), Encoding.UTF8, "application/json");
}
else
{
// 检查 AppKey 和 AppSecret
BaseResult result = BaseServicesLicenseManager.CheckService(appKey, appSecret, false, 0, 0, systemCode, permissionCode);
if (!result.Status)
{
var response = actionContext.Response = actionContext.Response?? new HttpResponseMessage();
response.Content = new StringContent(result.ToJson(), Encoding.UTF8, "application/json");
}
}
}
}
3、统一回传格式
///
/// ApiResultAttribute
/// 统一回传格式
///
/// 修改纪录
///
/// 2016-10-31 版本：1.0 宋彪 创建文件。
///
///
/// 宋彪
/// 2016-10-31
///
///
public class ApiResultAttribute : ActionFilterAttribute
{
///
/// 重写回传的处理
///
///
public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
{
// 快件跟踪接口传的是format，不用走这里
if (actionExecutedContext.Request.Properties.ContainsKey("format"))
{
// 若发生例外则不在这边处理 在异常中处理 ApiErrorHandleAttribute
if (actionExecutedContext.Exception != null)
return;
base.OnActionExecuted(actionExecutedContext);
var result = new ApiResultModel();
// 取得由 API 返回的状态码
result.Status = actionExecutedContext.ActionContext.Response.StatusCode;
// 取得由 API 返回的资料
result.Data = actionExecutedContext.ActionContext.Response.Content.ReadAsAsync
4、全局异常处理
using DotNet.Utilities;
using DotNet.Tracking.API.Common;
using DotNet.Tracking.API.Controllers;
using DotNet.Tracking.API.Models;
///
/// ApiErrorHandleAttribute
/// 全局异常处理
///
/// 修改纪录
///
/// 2016-10-31 版本：1.0 宋彪 创建文件。
///
///
/// 宋彪
/// 2016-10-31
///
///
public class ApiErrorHandleAttribute : System.Web.Http.Filters.ExceptionFilterAttribute
{
///
/// 异常统一处理
///
///
public override void OnException(System.Web.Http.Filters.HttpActionExecutedContext actionExecutedContext)
{
base.OnException(actionExecutedContext);
// 取得发生例外时的错误讯息
var errorMessage = actionExecutedContext.Exception.Message;
// 异常记录
string parameters = APIOperateContext.GetRequestParameters();
NLogHelper.Trace(actionExecutedContext.Exception, BaseSystemInfo.SystemCode + " ApiErrorHandleAttribute OnException 完整的请求地址及参数 ： " + parameters);
// 2016-11-01 加入异常邮件提醒
NLogHelper.InfoMail(actionExecutedContext.Exception, BaseSystemInfo.SystemCode + " ApiErrorHandleAttribute OnException 完整的请求地址及参数 ： " + parameters);
var result = new ApiResultModel()
{
Status = HttpStatusCode.BadRequest,
ErrorMessage = errorMessage
};
// 重新打包回传的讯息
actionExecutedContext.Response = actionExecutedContext.Request.CreateResponse(result.Status, result);
}
}
5、接口操作的上下文
using DotNet.Business;
using DotNet.Model;
using DotNet.Utilities;
///
/// APIOperateContext
/// 接口操作的上下文
/// 跟上下文有关的一些通用的东西放在这里处理
///
/// 修改纪录
///
/// 2016-10-31 版本：1.0 宋彪 创建文件。
///
///
/// 宋彪
/// 2016-10-31
///
///
public class APIOperateContext
{
///
/// 获取当前 操作上下文 (为每个处理浏览器请求的服务器线程 单独创建 操作上下文)
///
public static APIOperateContext Current
{
get
{
APIOperateContext oContext = CallContext.GetData(typeof(APIOperateContext).Name) as APIOperateContext;
if (oContext == null)
{
oContext = new APIOperateContext();
CallContext.SetData(typeof(APIOperateContext).Name, oContext);
}
return oContext;
}
}
#region Http上下文 及 相关属性

foreach (var key in nvc.AllKeys)
{
list.Add(key + "=" + nvc[key]);
}
var form = HttpContext.Current.Request.Form;
foreach (var key in form.AllKeys)
{
list.Add(key + "=" + form[key]);
}
string result = HttpContext.Current.Request.Url.AbsoluteUri + "?" + string.Join("&", list);
return result;
}
///
/// 分析 url 字符串中的参数信息
/// 针对get请求的
///
/// 输入的 URL
/// 输出 URL 的基础部分

foreach (Match m in mc)
{
nvc.Add(m.Result("$2").ToLower(), m.Result("$3"));
}

#endregion
}
7、统一回传格式实体
///
/// ApiResultModel
/// 统一回传格式实体
///
/// 修改纪录
///
/// 2016-10-31 版本：1.0 宋彪 创建文件。
///
///

///
public class ApiResultModel
{
public HttpStatusCode Status { get; set; }
//public JsonResult Data { get; set; }
public object Data { get; set; }
public string ErrorMessage { get; set; }
}
8、留言相关接口
///
/// MessageBookController
/// 留言相关接口
///
/// 修改纪录
///
/// 2016-10-31 版本：1.0 宋彪 创建文件。
///
///
/// 宋彪
/// 2016-10-31
///
///
[ApiAuthFilter]
public class CustomerMessageController : ApiController
{
///
/// 保存单号留言信息
///
///
///
[HttpPost]
//[AllowAnonymous] 不需要验证的就加这个标签
public IHttpActionResult Add([FromBody]MsgbookCusEntity messageBook)
{
BaseResult baseResult = new BaseResult();
if (string.IsNullOrWhiteSpace(messageBook.SystemFrom))
{
baseResult.Status = false;
baseResult.StatusMessage = "SystemFrom参数不可为空";
}
else
{
try
{
MsgbookCusManager manager = new MsgbookCusManager(APIOperateContext.BusinessDbHelper, APIOperateContext.Current.UserInfo);
MsgbookCusEntity model = new MsgbookCusEntity();
model.Id = Guid.NewGuid().ToString("N");
model.Message = messageBook.Message;
model.SendEmail = messageBook.SendEmail;
model.SendTelephone = messageBook.SendTelephone;
model.Message = messageBook.Message;
model.BillCode = messageBook.BillCode;
model.SystemFrom = messageBook.SystemFrom;
model.DeletionStateCode = 0;
manager.Add(model, false, false);
baseResult.Status = true;
baseResult.StatusMessage = "添加成功。";
}
catch (Exception ex)
{
NLogHelper.Warn(ex, "CustomerMessageController AddBillMessage 异常");
baseResult.Status = false;
baseResult.StatusMessage = "异常：" + ex.Message;
}
}
return Ok(baseResult);
}
///

list = manager.GetList(new KeyValuePair(MsgbookCusEntity.FieldBillCode, billCode)

9、接口调用方法

/// 测试留言接口调用

{
string url = "http://192.168.1.88:808/api/CustomerMessage/Add?";
WebClient webClient = new WebClient();
NameValueCollection postValues = new NameValueCollection();
postValues.Add("Message", "填写您的留言内容吧");
postValues.Add("SendEmail", "youemail@qq.com");
postValues.Add("SendTelephone", "021-60375335");
postValues.Add("Code", "661137858");
postValues.Add("AppKey", "wssavbcn");
postValues.Add("AppSecret", "350e66b1e6564b0a817163erwwwwe8");
postValues.Add("SystemFrom", "官网");
byte[] responseArray = webClient.UploadValues(url, postValues);
string response = Encoding.UTF8.GetString(responseArray);
return Content(response);
}
