https://localhost Xamarin.Mac httplclient

Question

我有一个本地webapi，我使用一个自签名的证书在Mac上运行，我能够使用浏览器(https://localhost:port/controller/method)到达webapi (用https://localhost:port/controller/method编写)，但是当我在Mojave上使用httpclient时，我会得到一个异常()。

System.DllNotFoundException: libc.dylib assembly:<unknown assembly> type:<unknown type> member:(null)

我已经阅读过了，似乎需要将DYLD_FALLBACK_LIBRARY_PATH设置为/usr/lib (我可以看到文件-- libc.dylib )，相信我应该将它作为环境变量添加到info.plist中，但它仍然失败，否则我做错了。

任何帮助都可以。

Answer 1

如果启用了强化运行时，请尝试将“允许DYLD环境变量权限”(com.apple.security.cs.allow-dyld-environment-variables)添加到Entitlements.plist中。

Answer 2

我只是复制libc.dylib。转到应用程序MonoBundle或参考资料文件夹。Dll可以在这里找到：https://github.com/facilityweb/Dlls/blob/master/libc.dylib

另一个解决方案是导入库MainClass，如下所示：

 static class MainClass
{
    static void Main(string[] args)
    {
        //solved mojave notfound dll exception
        IntPtr p = Dlfcn.dlopen("/usr/lib/libc.dylib", 0);

        NSApplication.Init();
        NSApplication.SharedApplication.Delegate = new AppDelegate();
        NSApplication.Main(args);
    }
}
