signalr 在创建 server.js 文件时生成错误
signalr generating error while creating server.js file
我在 Visual Studio 2015 Pro 下使用 Xamarin 创建 Android 的聊天应用程序。
我想为 SignalR 生成的代理创建一个物理文件，在此处描述：SignalR Hubs API Guide
因此，如前所述，我安装了 Microsoft.AspNet.SignalR.Utils NuGet 包。
我试过了：
signalr.exe ghp /path:"D:\WORKS\VISUALSTUDIO\ASPWEBSITE\ServerSignalR_ChatHub\ServerSignalR_ChatHub\bin"
但它总是给出以下错误：
SignalR Utility Version: 2.2.1.0

It generate empty server.js file
我做错了什么或遗漏了什么？
哦，伙计....经过大量研究和尝试，我终于找到了答案。
在错误中：
它说，无法加载程序集Newtonsoft.Json，版本=6.0.0.0。但是我有 Version=9.0.0.0
所以我只是强制卸载它并使用最小依赖版本安装它=6.0.0.0（在我的例子中它依赖于SignalR.Core.dll（v2.2.1））。
uninstall-package newtonsoft.json -force
install-package newtonsoft.json -version "6.0.4"
然后 运行:
signalr.exe ghp /path:"D:\WORKS\<path>\ServerSignalR_ChatHub\bin"
并成功生成server.js!!
我想我会在 Visual Studio 的项目属性“构建事件”下添加使用“预构建事件命令行”的解决方案。
我没有使用我的程序的已安装包（否则效果很好），而是将旧 NewtonSoft 文件的副本放在解决方案文件夹级别的“OldNewton”目录中。我记下了 SignalR.Utils 可执行文件的安装目录。然后我编写了一些命令来更改到 bin 文件夹，复制旧的 NewtonSoft 文件和 Utils 文件，执行 signalR ghp 命令来创建集线器脚本，然后将文件复制到我想要的位置。我还向 backup/restore 任何现有的 NewtonSoft 文件添加了一些清理命令和一些命令。您可能希望将 SignalR.Utils 文件复制到 OldNewton 文件旁边的它们自己的目录中，以防包更新。我认为它看起来比实际要复杂得多。您可以删除 echo 命令，甚至可能删除备份和清理命令以使其更短。有几种方法可以做到这一点，但这是我选择的方法。
