.Net Core Api 使用版本控制

1，安装Microsoft.AspNetCore.Mvc.Versioning

NET Core Mvc中，微软官方提供了一个可用的Api版本控制库Microsoft.AspNetCore.Mvc.Versioning。

2，修改Startup类

这里我们需要在Startup类的ConfigureService方法中添加以下代码。

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
            services.AddApiVersioning(o =>
            {
                o.ReportApiVersions = true;
                o.AssumeDefaultVersionWhenUnspecified = true;
                o.DefaultApiVersion = new ApiVersion(1, 0);
                //o.ApiVersionReader = new HeaderApiVersionReader("x-api-version");
            });
        }

3，代码

    //版本1控制器
    [ApiVersion("1.0", Deprecated = true)]
    [Route("api/values")]
    [ApiController]
    public class ValuesV1Controller : ControllerBase
    {
        [HttpGet]
        public IEnumerable<string> Get()
        {
            return new string[] { "这是版本1.0返回的——数据1", "这是版本1.0返回的——数据2" };
        }
    }

    //版本2控制器
    [ApiVersion("2.0")]
    [Route("api/values")]
    [ApiController]
    public class ValuesV2Controller : ControllerBase
    {
        [HttpGet]
        public IEnumerable<string> Get()
        {
            return new string[] { "这是版本2.0返回的——数据1", "这是版本2.0返回的——数据2" };
        }
    }

4，访问

https://localhost:44319/api/values

https://localhost:44319/api/values?api-version=1.0

https://localhost:44319/api/values?api-version=2.0
