XmlException：.NET内核中缺少根元素
XmlException：.NET内核中缺少根元素
提问于 2021-02-06 10:25:09
我正在使用SoapCore ( ASP.NET Core的Soap协议中间件)来使用本地机器上现有的soap文件(.WSDL)创建soap服务器。
我在appsettings.json中使用以下配置
"FileWSDL":
{
"UrlOverride": "/Service.asmx",
"WebServiceWSDLMapping":
{
"Service.asmx":
{
"WsdlFile": "SOAP.wsdl",
"SchemaFolder": "D: /",
"WsdlFolder": "D: /"
}
}
},
"VirtualPath": "",问题是，当我试图运行应用程序时，我会得到以下错误：
处理请求时发生了未处理的异常。
XmlException:根元素丢失。
System.Xml.XmlTextReaderImpl.Throw (例外e)
有人帮忙吗？
我正在使用ASP.NET Core3.1。
我的Startup.cs
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.ServiceModel;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.DependencyInjection.Extensions;
using Microsoft.Extensions.Hosting;
using Models;
using SoapCore;
using Microsoft.Extensions.Configuration;
namespace SoapServer
{
public class Startup
{
private readonly IConfiguration Configuration;
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
// This method gets called by the runtime. Use this method to add services to the container.
// For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
public void ConfigureServices(IServiceCollection services)
{
services.TryAddSingleton<ISampleService, SampleService>();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
var settings = Configuration.GetSection("FileWSDL").Get<WsdlFileOptions>();
settings.AppPath = env.ContentRootPath; // The hosting environment root path
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapGet("/", async context =>
{
await context.Response.WriteAsync("Hello World!");
});
});
app.UseSoapEndpoint<ISampleService>("/Service.asmx", new BasicHttpBinding(), SoapSerializer.XmlSerializer, false, null, settings);
}
}

所有xml文件(wsdl文件也是xml )必须有一个根元素：https://www.w3schools.com/xml/xml_syntax.asp
XML文档必须包含一个根元素，该根元素是所有其他元素的父元素。
有效的例子：
<root>
<child>
<subchild>.....</subchild>
</child>
<child>
<subchild>.....</subchild>
</child>
</root>InValid示例：
<child>
<subchild>.....</subchild>
</child>
<child>
<subchild>.....</subchild>
</child>所以，要么您的wsdl无效，要么应用程序无法访问它，而且您正在使用一个空文件。

我也遇到了同样的问题，我的XML很好--只是找不到它。
我通过设置设置对象的AppPath值来解决这个问题：
var settings = Configuration.GetSection("FileWSDL").Get<WsdlFileOptions>();
settings.AppPath = AppDomain.CurrentDomain.BaseDirectory;
app.UseSoapEndpoint<Models.RateLinxWS>("/Shipping.asmx", new BasicHttpBinding() { Name = "RateLinxWSSoap", Namespace = "RateLinxWSSoap" }, SoapSerializer.XmlSerializer, false,null, settings);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
