我想从第三方dll使用Tomasz Janczuk的awesome edgejs库调用一个函数。根据我收到的错误消息,代码可能会或可能不会返回信息。错误信息(见下文)我得到说代码需要一个字符串,但是取而代之的是取回ExpandoObject。我已经尝试了几个不同版本的代码,这些代码基于edgejs github页面上的示例,但它们都返回相同的错误。这个错误表明它只是将一个字符串转换为一个扩展对象,但到目前为止我没有成功。任何有关这个问题的帮助将非常感谢。我一直在努力争取这个工作的时间比我想要承认的要长。基于110_clr_instance.js样品在edgejs github上Edge.js强制转换为字符串expandoobject
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:
C:\Users\csnow\NodeApps\MarshallDataEdge\node_modules\edge\lib\edge.js:161
return edge.initializeClrFunc(options);

但后来我通过代码加强使用webstorm,并从边缘发现了这个错误。 JS。 ReferenceError: options is not defined
感谢很多的帮助托马斯! – SnowballsChance
