nginx 代理转发 wcf接口

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：

    class DbCxt
    {
        private static string _connStr = "";

        static DbCxt()
        {
            FbConnectionStringBuilder connBuilder = new FbConnectionStringBuilder();
            connBuilder.DataSource = "localhost";
            connBuilder.UserID = "sysdba";
            connBuilder.Password = "1234";
            connBuilder.Database = "wms";
            connBuilder.Charset = "utf8";
            connBuilder.Dialect = 3;
            connBuilder.ServerType = FbServerType.Default;

            _connStr = connBuilder.ConnectionString;
            
        }

        public static IDbContext NewDbContext()
        {
            return new DbContext().ConnectionString(_connStr, new DB2Provider()
                , FirebirdClientFactory.Instance);
        }

        public static string ConnStr()
        {
            return _connStr;
        }
    }

wcf接口：

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

接口实现：

    public class WmsService : IWmsService
    {
        public DtoResult<DtoUser> AddUser(DtoUser usr)
        {
            if (usr != null)
            {
                DateTime creTime = DateTime.Now;
                DateTime.TryParse(usr.CreTime, out creTime);
                using (var db = DbCxt.NewDbContext())
                {
                    int count = db.Insert("m_user")
                        .Column("code", usr.Code)
                        .Column("label", usr.Label)
                        .Column("cre_time", creTime)
                        .Column("remark", usr.Remark)
                        .Execute();
                    return new DtoResult<DtoUser>() {State = 1, Data = usr};
                }
            }
            return new DtoResult<DtoUser>() {State = 0, Msg = "用户不能为空"};
        }
    }

wcf宿主：

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

wcf配置：

  <system.serviceModel>
    <services>

      <service name="Wms.Service.WmsService" behaviorConfiguration="http" >
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:20001/WmsService"/>
          </baseAddresses>
        </host>
        <endpoint binding="webHttpBinding" contract="Wms.Service.IWmsService" behaviorConfiguration="web"></endpoint>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="mex">
          <serviceMetadata/>
        </behavior>
        <behavior name="http">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"  httpHelpPageEnabled="true"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp helpEnabled="true"/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
  </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/

        $scope.data = {
            Code: '', Label: '', CreTime: new Date().Format('yyyy-MM-dd hh:mm:ss'), Remark: '', Pwd:'123456'
        };

        $scope.save = function () {
            $http.post('/wmsService/addUser', $scope.data).then(function (value) {
                console.log(value);
            })
        };

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。

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

enginx其他配置都取默认，除端口改为10005以外。
