How to add JsonArrayObject in JsonArray

Question

Here I am trying to implement Ocelot for API Gateway for my multiple micro services. I have Seven Micro services which have lots of API almost 550 APIs. While preparing ocelot.json it is a huge file which seems unmaintainable. For which I want to have different json array objects for each services. Those array objects to be inserted to in routes array of ocelot.json. I have a sample ocelot.json like this:

{
   "Routes": [
    {
      "DownstreamPathTemplate": "/api/ObjectHeads/GetObjectHeadFromBudget?{everything}",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": 59035
        }
      ],
      "UpstreamPathTemplate": "/ObjectHeads/GetObjectHeadFromBudget?{everything}",
      "UpstreamHttpMethod": [ "Get" ]
    },
    {
      "DownstreamPathTemplate": "/api/ObjectHeads/GetObjectHeadByDepartmentWise?{everything}",
      "DownstreamScheme": "https",
      "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": 44358
        }
      ],
      "UpstreamPathTemplate": "/ObjectHeads/GetObjectHeadByDepartmentWise?{everything}",
      "UpstreamHttpMethod": [ "Get" ]
    }
   ],
   "GlobalConfiguration": {
   "BaseUrl": "https://localhost:7000"
   }
}

It is working absolutely fine I am able to perform get, post from different micro services. Now my concern is there a way to add json array objects in routes array in the ocelot.json? I am bit new to the json as I never worked on it. Is there a way out for managing such stuff. I am sure that somebody may have gone through such situation, there may be a solution. My program.cs looks simple like this.

var builder = WebApplication.CreateBuilder(args);

builder.Configuration
    .AddJsonFile("ocelot.json")
    .AddJsonFile($"ocelot.{builder.Environment.EnvironmentName}.json");

 builder.Services.AddOcelot()
    .AddDelegatingHandler<RequestLogger>()
    .AddCacheManager(settings => settings.WithDictionaryHandle())
    .AddCustomLoadBalancer((serviceProvider, downstreamRoute, serviceDiscoveryProvider) =>
    {
        return new CustomLoadBalancer(serviceDiscoveryProvider.Get);
    });

var app = builder.Build();

app.UseOcelot();

app.Run();

Any solutions and suggestions are highly appreciated please.

Answer 1

you can download json directly , not using config

    var path = @"C:\...";
    // or maybe you can try this
    var path = Directory.GetCurrentDirectory();

    var filePath = Path.Combine(path, "ocelot.json");
    var json = File.ReadAllText(filePath);

    var jObj = JObject.Parse(json);

    var newRoute = new
    {
        DownstreamPathTemplate = "/api/ObjectHeads/GetObjectHeadByDepartmentWise?{everything}",
        DownstreamScheme = "https",
        DownstreamHostAndPorts = new[] {
        new {
         Host= "localhost",
          Port= 44358
        }
      },
        UpstreamPathTemplate = "/ObjectHeads/GetObjectHeadByDepartmentWise?{everything}",
        UpstreamHttpMethod = new string[] { "Get" }
    };
    
     ((JArray)jObj["Routes"]).Add(JObject.FromObject(newRoute));
     
      File.WriteAllText(filePath,jObj.ToString());
