.net core 跨域

第一步：修改Startup.cs

一：找到ConfigureServices()方法

网站根目录打开Startup.cs文件，找到ConfigureServices()方法

输入如下代码

 //跨域服务注册
            services.AddCors(m=>m.AddPolicy("any",a=>a.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader()));

二：找到Configure()方法

输入如下代码

 //跨域
app.UseCors();

完整代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;
using Microsoft.OpenApi.Models;
using swaggertest.Utility;

namespace swaggertest
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            SqlHelper.ConStr = Configuration["ConStr"].Trim();

            //跨域服务注册
            services.AddCors(m=>m.AddPolicy("any",a=>a.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader()));

            //Swagger
            services.AddSwaggerGen(m=>{
                m.SwaggerDoc("v1", new OpenApiInfo { Title="swaggerTest",Version="v1" });
            });
            services.AddControllers();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseRouting();

            app.UseAuthorization();

            //Swagger
            app.UseSwagger();
            app.UseSwaggerUI(s=> {
                //下面路径里的v1必须和SwaggerDoc（）第一个参数一致
                s.SwaggerEndpoint("/swagger/v1/swagger.json", "swaggerTast");
            });

            //跨域
            app.UseCors();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }
    }
}

第二步：控制器

一、引入using Microsoft.AspNetCore.Cors;

二、控制器Controller 或者方法Action上面添加特性

 [EnableCors("any")]

这里的"any"对应Startup.cs文件ConfigureServices方法里的"any"

//跨域服务注册
            services.AddCors(m=>m.AddPolicy("any",a=>a.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader()));

控制器完整代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Cors;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using swaggertest.Models;

namespace swaggertest.Controllers
{
    [EnableCors("any")]
    [Route("api/[controller]/[Action]")]
    //[ApiController]
    public class ProductsController : ControllerBase
    {
        [HttpGet]
        public IActionResult GetProduct()
        {
          List<Products> products= Products.ListAll();
            return new JsonResult(products);
        }
    }
}
