因为.net core 的System.Net 中没有提供WebProxy这个方法,所以可以根据需求实现一个.

    public class CoreWebProxy : IWebProxy{public readonly Uri Uri;private readonly bool bypass;public CoreWebProxy(Uri uri, ICredentials credentials = null, bool bypass = false){Uri = uri;this.bypass = bypass;Credentials = credentials;}public ICredentials Credentials { get; set; }public Uri GetProxy(Uri destination) => Uri;public bool IsBypassed(Uri host) => bypass;public override int GetHashCode(){if (Uri == null){return -1;}return Uri.GetHashCode();}}

参考:

• Specify proxy in asp.net core rc2
• .Net Core中使用Proxy请求数据
