无法在简单的Grapevine服务器示例中加载类型HttpListener [英] Cannot load type HttpListener in simple Grapevine server example

问题描述

我正在尝试使用Grapevine来实现一个简单的C#REST服务器.我在OSX上使用Xamarin Studio.我拉了Grapevine 4.0.0.195作为包装.

I am trying to use Grapevine to implement a simple C# REST server. I am using Xamarin Studio on OSX. I pulled Grapevine 4.0.0.195 as a package.

但是，当我尝试运行在> https://sukona.github.io/Grapevine上给出的示例时/，出现此错误:

However, when I try to run the example given on https://sukona.github.io/Grapevine/, I get this error:

System.TypeLoadException:无法加载类型 程序集"Grapevine"中的"Grapevine.Interfaces.Server.HttpListener"， 版本= 4.0.0.195，文化=中性，PublicKeyToken =空'.在 Grapevine.Server.RestServer..ctor()[0x00006]在 < 5da3c1fcf3364795b3df98bfc8b714aa>:0在TestServer.MainClass.Main (System.String [] args)[0x0000b]在 /Users/blah/Projects/Test/TestServer/Program.cs:12

System.TypeLoadException: Could not load type 'Grapevine.Interfaces.Server.HttpListener' from assembly 'Grapevine, Version=4.0.0.195, Culture=neutral, PublicKeyToken=null'. at Grapevine.Server.RestServer..ctor () [0x00006] in <5da3c1fcf3364795b3df98bfc8b714aa>:0 at TestServer.MainClass.Main (System.String[] args) [0x0000b] in /Users/blah/Projects/Test/TestServer/Program.cs:12

我检查了Grapevine大会，发现确实存在HttpListener.

I inspected the Grapevine assembly and found that HttpListener is indeed present.

这是我的Program.cs:

using System;
using Grapevine.Server;

namespace TestServer
{
    public sealed class MainClass
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");

            using (var server = new RestServer())
            {
                server.Start();
                Console.ReadLine();
                server.Stop();
            }
        }
    }
}

推荐答案

我也遇到了同样的问题，并发现了与关于ExtendedProtectionSelector提到的Scott Offen(感谢您的出色工作！)相同的响应.

I also ran into the same issue and and discovered the same response as Scott Offen (thank you for your awesome work btw!) mentioned about ExtendedProtectionSelector.

所以我回到了他以前的版本，并且能够使用3.0.1版的葡萄树在xamarin中制作葡萄树

So I went back to his previous version and I was able to make grapevine work in xamarin using grapevine version 3.1.0

它也不会立即可用(我正在为ios构建，如果您遇到与android相同的问题，则为idk).它将给您一些有关日志记录的错误，因此我在他的日志记录代码中到处都进行了Ctrl + F并进行了更改.我几乎注释掉了EventLogger.cs

It wont work right out of the box either( I was building for ios, idk if you would run into the same issues for android). It will give you some errors about logging so I did Ctrl+F everywhere in his code about logging and changed it. I pretty much commented out everything in EventLogger.cs

然后在RESTServer中，无论哪里有EventLogger报告错误，我都将其简单地更改为Console.Writeline以描述调试时的错误.

Then in RESTServer, wherever there was a EventLogger to report the error, i simply changed it to Console.Writeline to describe the error when debugging.

祝你好运！
