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(, );
//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
