【ocelot】ocelot第一步配置（配置文件到数据库中）

配置环境.net core2.2

数据库sql server2010

vs2019

第一步：然后在sqlserver上（在自己库中也可以创建一个新的库）执行如下两个sql创建表

USE [database]
GO

/****** Object:  Table [dbo].[OcelotGlobalConfiguration]    Script Date: 2019-11-22 10:36:24 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

GO

GO

USE [database]
GO

/****** Object:  Table [dbo].[OcelotReRoutes]    Script Date: 2019-11-22 10:36:31 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[OcelotReRoutes](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [OcelotGlobalConfigurationId] [int] NOT NULL,
    [UpstreamPathTemplate] [nvarchar](150) NOT NULL,
    [UpstreamHttpMethod] [nvarchar](50) NOT NULL,

    [IsStatus] [int] NOT NULL,
    [AddTime] [date] NOT NULL,
 CONSTRAINT [PK_OcelotReRoutes] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[OcelotReRoutes] ADD  CONSTRAINT [DF_OcelotReRoutes_IsStatus]  DEFAULT ((1)) FOR [IsStatus]
GO

ALTER TABLE [dbo].[OcelotReRoutes] ADD  CONSTRAINT [DF_OcelotReRoutes_AddTime]  DEFAULT (getdate()) FOR [AddTime]
GO

EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'主键' , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'OcelotReRoutes', @level2type=N'COLUMN',@level2name=N'Id'

GO

第二步：安装 Ocelot.Encapsulation包，主要是给ocelot的封装。该nuget包是基于 https://github.com/yilezhu/Ocelot.ConfigAuthLimitCache，其中做了一些改动，具体包还是以包指定的源码连接。

然后在Startup>ConfigureServices中插入如下代码

            services.AddOcelot()
                .AddAuthLimitCache(option =>
                {
                    option.DbConnectionStrings = "Server=.;Database=Ocelot;User ID=sa;Password=sasa;";//Database是自己刚刚生成那个数据的库
                });

以及在Startup>Configure插入如下代码

app.UseAhphOcelot((ocelotBuilder, pipelineConfiguration) =>
            {
                
            }).Wait();

 请根据如上图的配置规则结束。
