我试图使用Tomasz的可怕的edgejs库从第三方dll中调用一个函数。根据我得到的错误消息,代码可能返回信息,也可能不返回信息。我收到的错误消息(见下面)说,代码需要一个字符串,但是正在返回一个ExpandoObject。我根据edgejs页面上的示例尝试了几种不同版本的代码,但它们都返回相同的错误。这个错误可能意味着它只是将扩展对象转换成字符串的问题,但是到目前为止我还没有成功。如果能在这个问题上提供任何帮助,我们将不胜感激。我一直在努力让这件事起作用的时间比我愿意承认的时间还要长。
基于 110 示例的edgejs github:代码
var edge = require('edge');
var createSerial = edge.func({
source: {/*
using System;
using System.Threading.Tasks;
public class Startup
{
public async Task<object> Invoke(string location)
{
var serial = new Serial(location);
return new {
validateLocation = (Func<object,Task<object>>)(
async (location) =>
{
serial.ValidateLocation((string)location);
return serial.IsValid;
}
)
};
}
}
public class Serial
{
public static Connection conn = new Connection("https://companyname.moraware.net/companyname/api.aspx", "username", "password");
public bool IsValid { get; private set; }
public Serial(bool isValid)
{
this.IsValid = isValid;
}
public void ValidateLocation(string location)
{
conn.AutoRefreshOnTimeout = true;
if (!conn.Connected) { conn.Connect(); }
this.IsValid = conn.GetInventoryLocations().Any(x => x.InventoryLocationName == location);
if (conn.Connected) { conn.Disconnect(); }
}
} */},
references: ['JobTrackerAPI4.dll','Newtonsoft.Json.dll']
});
var serial = createSerial("A01-01", true);
console.log(serial.validateLocation(null, true));控制台错误输出:

return edge.initializeClrFunc(options);

Process finished with exit code 1但随后我使用webstorm完成了代码,并从edge.js中发现了这个错误。ReferenceError: options is not defined

将C#文本传递给edge.func的方式缺少了function () {...}包装器。它应该是:
edge.func({
source: function () {/*
// C# code goes here
*/},
...
});而不是
edge.func({
source: {/*
// C# code goes here
*/},
...
});https://stackoverflow.com/questions/41128170
