注： 修改UPSTREAMHOST 字段为可为空
开始集成：
1.在网关项目中添加对Ocelot.ConfigAuthLimitCache的引用
2.在网关项目的Startup.cs 中修改ConfigureServices节点 标红部分
services.AddOcelot(Configuration).AddAuthLimitCache(opt=> { opt.DbConnectionStrings = Configuration.GetSection("Setting")["ConfigDBConnction"]; }).AddConsul();
3.在配置文件中添加数据库连接 蓝色部分
"Setting": { "Port": "5001", "ConfigDBConnction": "Data Source=192.168.xxx.xxx/orcl;User ID=xxx;Password=xxx;" },
4.在Program.cs中移除对原配置文件的依赖 注释部分
public static IWebHostBuilder CreateWebHostBuilder(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup<Startup>() .UseUrls($"http://*:{StartPort}"); //.ConfigureAppConfiguration((hostingContext, builder) => //{ // builder.AddJsonFile("configuration.json", false, true); //});
5.修改Ocelot.ConfigAuthLimitCache项目的数据仓储实现
增加

注：需要添加之前的CommonHelper引用或者 单独添加Oracle.ManagedDataAccess.Core nuget包引用
至此搭建完毕 将配置文件部分的内容移动到数据库即可。
