NETCORE

NETCORE - 调用第三方接口

调用方式： WebApi 

创建两个 NetCore WebApi 项目 ，框架：.net5

　1) 项目：NETCORE.ConSul

　2) 项目：NETCORE.ConSul.Service

一. 项目 NETCORE.ConSul.Service

1.  新建接口

namespace NETCORE.Consul.Service.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class PenController : ControllerBase
    {
        //测试接口
        [Route("GetPenInfo")]
        [HttpGet]
        public string GetPenInfo()
        {
            Task.Run(() => { Console.WriteLine($" get a new pen , Host: {0}", HttpContext.Request.Host.Value); });
            return "success! get a new pen !";
        }
    }
}

2. 修改IP地址与端口：

路径：Properties / launchSettings.json

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:24384",
      "sslPort": 44335
    }
  },
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "NETCORE.Consul.Service": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "dotnetRunMessages": "true",
      "applicationUrl": "https://10.10.50.99:5055;http://10.10.50.99:5056",
      "jsWebView2Debugging": true
    }
  }
}

 3. 调试

接口访问地址：https://10.10.50.99:5055/api/Pen/GetPenInfo

 

 二. 项目 NETCORE.Consul

1.  修改IP地址与端口：

路径：Properties / launchSettings.json

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://10.10.50.99:19691",
      "sslPort": 44328
    }
  },
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "NETCORE.ConSul": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "dotnetRunMessages": "true",
      "applicationUrl": "https://10.10.50.99:5001;http://10.10.50.99:5000"
    }
  }
}

 2. 注入 HTTPClient

在 startup.cs 中修改 ConfigureServices 方法 

        public void ConfigureServices(IServiceCollection services)
        {
            //用于调用博客园接口
            services.AddHttpClient("ServiceBlogs", x =>
            {
                x.BaseAddress = new Uri("https://www.cnblogs.com");
                x.DefaultRequestHeaders.Add("Cache-Control", "no-cache");
            });
            //用于调用Service1接口
            services.AddHttpClient("ServiceService1", x =>
            {
                x.BaseAddress = new Uri("https://10.10.50.99:5055");
                x.DefaultRequestHeaders.Add("Cache-Control", "no-cache");
            }).ConfigurePrimaryHttpMessageHandler(() =>//防止报ssl错误
            {
                return new HttpClientHandler()
                {
                    ServerCertificateCustomValidationCallback = HttpClientHandler.DangerousAcceptAnyServerCertificateValidator
                };
            });

            services.AddControllers();
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new OpenApiInfo { Title = "NETCORE.ConSul", Version = "v1" });
            });
        }

3. 新增接口

namespace NETCORE.ConSul.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class BookController : ControllerBase
    {
        IHttpClientFactory _clientFactory;
        public BookController(IHttpClientFactory clientFactory)
        {
            _clientFactory = clientFactory;
        }

        [Route("CallPen")]
        [HttpPost]
        public async Task<IActionResult> CallPen()
        {
            var client = _clientFactory.CreateClient("ServiceService1");//必须与startup里面注入的名称对应
            //var content = new StringContent("");
            //content.Headers.ContentType = new MediaTypeHeaderValue("application/x-www-form-urlencoded");
            var response = await client.GetAsync("api/pen/GetPenInfo");
            var sss = response.Content.ReadAsStringAsync().Result; 
            return Ok(sss); 
        }
    }
}
