1. 添加js跨域访问。

在Startup.cs文件中  public IServiceProvider ConfigureServices(IServiceCollection services)中添加

 services.AddCors(
                options => options.AddPolicy(
                    "AlloweDomain",
                    builder => builder
                        .WithOrigins(
                            // App:CorsOrigins in appsettings.json can contain more than one address separated by comma.
                            _appConfiguration["App:CorsOrigins"]
                                .Split(",", StringSplitOptions.RemoveEmptyEntries)
                                .Select(o => o.RemovePostFix("/"))
                                .ToArray()
                        )
                        .AllowAnyHeader()
                        .AllowAnyMethod()
                        .AllowCredentials()
                )
            );

在允许跨域的Controller中添加。也可以在ControllerBase中添加允许全部继承继承类的Controller。

 [EnableCors("AlloweDomain")]
  public class FileGetController : ServiceControllerBase
{

}

在appsettings.json添加允许访问的域名。

"App": { 
    "CorsOrigins": "http://localhost:4200,http://localhost:8080,http://localhost:8081,https://www.baidu.com"
  },
