enginx 代理转发 wcf接口

Posted 2020-12-28 jonney

前言

以前对比过enginx和其他几个web服务器（IIS，Apache，lighttpd）的处理静态文件的能力，enginx是最好的，甚至超过其他的几倍。

虽说enginx官方声明在Windows上的表现不如Linux等OS，经过测试enginx的异步处理和响应真出乎意料。

正文

测试的目的和思路：

后台接口用wcf，json作为请求和响应的类型，HTTP协议。

纯前端用angular及路由，enginx作为web服务器。

凡请求后台接口enginx都代理转发到wcf处理。

测试上下文：

Firebird3.0.3标准版、ORM微框架FluentData、VS2015、WebStorm2017.

数据库访问：

 1     class DbCxt
 2     {
 3         private static string _connStr = "";
 4 
 5         static DbCxt()
 6         {
 7             FbConnectionStringBuilder connBuilder = new FbConnectionStringBuilder();
 8             connBuilder.DataSource = "localhost";
 9             connBuilder.UserID = "sysdba";
10             connBuilder.Password = "1234";
11             connBuilder.Database = "wms";
12             connBuilder.Charset = "utf8";
13             connBuilder.Dialect = 3;
14             connBuilder.ServerType = FbServerType.Default;
15 
16             _connStr = connBuilder.ConnectionString;
17             
18         }
19 
20         public static IDbContext NewDbContext()
21         {
22             return new DbContext().ConnectionString(_connStr, new DB2Provider()
23                 , FirebirdClientFactory.Instance);
24         }
25 
26         public static string ConnStr()
27         {
28             return _connStr;
29         }
30     }

wcf接口：

1     [ServiceContract]
2     public interface IWmsService
3     {
4         [OperationContract]
5         [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
6         DtoResult<DtoUser> AddUser(DtoUser usr);
7     }

接口实现：

 1     public class WmsService : IWmsService
 2     {
 3         public DtoResult<DtoUser> AddUser(DtoUser usr)
 4         {
 5             if (usr != null)
 6             {
 7                 DateTime creTime = DateTime.Now;
 8                 DateTime.TryParse(usr.CreTime, out creTime);
 9                 using (var db = DbCxt.NewDbContext())
10                 {
11                     int count = db.Insert("m_user")
12                         .Column("code", usr.Code)
13                         .Column("label", usr.Label)
14                         .Column("cre_time", creTime)
15                         .Column("remark", usr.Remark)
16                         .Execute();
17                     return new DtoResult<DtoUser>() {State = 1, Data = usr};
18                 }
19             }
20             return new DtoResult<DtoUser>() {State = 0, Msg = "用户不能为空"};
21         }
22     }

wcf宿主：

1         static void Main(string[] args)
2         {
3             ServiceHost host = new ServiceHost(typeof(Wms.Service.WmsService));
4             host.Open();
5             Console.WriteLine("已启动");
6             Console.WriteLine("回车键退出");
7             Console.ReadLine();
8         }

wcf配置：

 1   <system.serviceModel>
 2     <services>
 3 
 4       <service name="Wms.Service.WmsService" behaviorConfiguration="http" >
 5         <host>
 6           <baseAddresses>
 7             <add baseAddress="http://localhost:20001/WmsService"/>
 8           </baseAddresses>
 9         </host>
10         <endpoint binding="webHttpBinding" contract="Wms.Service.IWmsService" behaviorConfiguration="web"></endpoint>
11       </service>
12     </services>
13 
14     <behaviors>
15       <serviceBehaviors>
16         <behavior name="mex">
17           <serviceMetadata/>
18         </behavior>
19         <behavior name="http">
20           <serviceMetadata httpGetEnabled="true"/>
21           <serviceDebug includeExceptionDetailInFaults="true"  httpHelpPageEnabled="true"/>
22         </behavior>
23       </serviceBehaviors>
24       <endpointBehaviors>
25         <behavior name="web">
26           <webHttp helpEnabled="true"/>
27         </behavior>
28       </endpointBehaviors>
29     </behaviors>
30   </system.serviceModel>

前端页面：

js提交代码：Note 请求URL最前的/不能省，因为后面enginx配置代理时不允许前缀后面加/

1         $scope.data = {
2             Code: \'\', Label: \'\', CreTime: new Date().Format(\'yyyy-MM-dd hh:mm:ss\'), Remark: \'\', Pwd:\'123456\'
3         };
4 
5         $scope.save = function () {
6             $http.post(\'/wmsService/addUser\', $scope.data).then(function (value) {
7                 console.log(value);
8             })
9         };

enginx代理转发部分配置：~*表示URL不区分大小写匹配，因为默认wcf也不区分。

1         location ~* /WmsService/ {
2             proxy_pass   http://127.0.0.1:20001;
3         }

enginx其他配置都取默认，除端口改为10005以外。
