[英]Adjust MVC 4 WebApi XmlSerializer to lose the nameSpace
我正在开发一个MVC WebAPI,它使用EF和POCO类进行存储。 我想要做的是从XML中删除命名空间,以便端点返回并接受没有它的xml对象。 (json工作得很好)
<ACCOUNT xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/Platform.Services.AccountService.Data">
<id>22</id>
<City i:nil="true"/>
<Country i:nil="true"/>
<Email>testas@email.com</Email>
<Phone i:nil="true"/> ...
我希望这能奏效
<ACCOUNT>
<id>22</id>
<City i:nil="true"/>
<Country i:nil="true"/>
<Email>testas@email.com</Email>
<Phone i:nil="true"/> ...
希望无需用一堆属性来装饰POCO。
我已经为此设置了一个测试解决方案,实际上,这些方法很受欢迎(必须是我系统中的其他一些问题)。 无论如何 - 我使用这个解决方案的结果是:
<ArrayOfAccount>
<Account>
<id>22</id>
<name>TestAcc</name>
<parentid xmlns:d3p1="http://www.w3.org/2001/XMLSchema-instance" d3p1:nil="true"/>
<status_id xmlns:d3p1="http://www.w3.org/2001/XMLSchema-instance" d3p1:nil="true"/>
<Email>Test@Test.com</Email>
</Account>
</ArrayOfAccount>
摆脱了顶部的架构,但现在搞砸了属性:(这是一个示例项目的链接
这里的答案是从ASP.NET Web API中标记删除XML中的命名空间 。
如果您根本不想装饰您的POCO,请使用第一个选项:
config.Formatters.XmlFormatter.UseXmlSerializer = true;
如果使用选项2,则可能需要添加对System.Runtime.Serialization
的引用
假设这样的帖子接受设置正确:
GET http:// ANY OLD SERVER / api / foos / 5接受:application / xml
调节器
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Runtime.Serialization;
using System.Web.Http;
namespace CutomXmlFormater.Controllers
{
//[DataContract(Namespace = "")]
public class Foo
{
//[DataMember]
public string Bar { get; set; }
}
public class FoosController : ApiController
{
// GET api/foos/5
public Foo Get(int id)
{
return new Foo() { Bar = "Test" };
}
}
}
配置(App_Start / WebApiConfig)
//(Use this is you don't go the data contact and model annotation route)
config.Formatters.XmlFormatter.UseXmlSerializer = true;
结果
(带注释和数据联系):
<Foo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><Bar>Test</Bar></Foo>
或者(使用XML序列化程序路由):
<Foo xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><Bar>Test</Bar></Foo>
也许你可以试试这个:
将默认的XmlFormatter替换为您自己的:
GlobalConfiguration.Configuration.Formatters.Add(new CustomXmlFormatter());
GlobalConfiguration.Configuration.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.XmlFormatter);
并使用XmlSerializer强制它,在序列化期间指定空命名空间,如下所示:
public CustomXmlFormatter()
{
SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/xml"));
SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/xml"));
Encoding = new UTF8Encoding(false, true);
}
protected override bool CanReadType(Type type)
{
if (type == (Type)null)
throw new ArgumentNullException("type");
if (type == typeof(IKeyValueModel))
return false;
return true;
}
protected override bool CanWriteType(Type type)
{
return true;
}
protected override Task OnReadFromStreamAsync(Type type, Stream stream, HttpContentHeaders contentHeaders, FormatterContext formatterContext)
{
return Task.Factory.StartNew(() =>
{
using (var streamReader = new StreamReader(stream, Encoding))
{
var serializer = new XmlSerializer(type);
return serializer.Deserialize(streamReader);
}
});
}
protected override Task OnWriteToStreamAsync(Type type, object value, Stream stream, HttpContentHeaders contentHeaders, FormatterContext formatterContext, System.Net.TransportContext transportContext)
{
var serializer = new XmlSerializer(type);
return Task.Factory.StartNew(() =>
{
using (var streamWriter = new StreamWriter(stream, Encoding))
{
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
serializer.Serialize(streamWriter, value, ns);
}
});
}
}
自定义XML序列化程序从这里被盗,因此未经测试。
这应该序列化没有编写命名空间的对象。 我不确定它是否可以用于反序列化OOTB,你可能不得不尝试提供事件并处理UnknownElement或UnknownNode事件的XmlSerializer.Deserialize()
重载 。
自从我搞砸MVC 4以来已经有一段时间了,但我们最终用XmlSerializer替换了默认的格式化程序,如下所示:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings = GetSerializeSettings();
GlobalConfiguration.Configuration.Formatters.XmlFormatter.UseXmlSerializer = true;
}
internal JsonSerializerSettings GetSerializeSettings()
{
return new JsonSerializerSettings
{
Formatting = Formatting.Indented,
ContractResolver = new CamelCasePropertyNamesContractResolver(),
Converters = new List<JsonConverter> { new IsoDateTimeConverter() }
};
}
这可能会有所帮助......我知道我们还使用你说你不想做的POCO上的属性来定制属性名称,但那是因为我们希望它们是驼峰式的。
我已经定制了Boris对MVC Webapi 5的回答。使用以下任一http头使用CustomFormatter渲染结果:
接受:application / xml
接受:text / xml
WebApiConfig.cs:
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
GlobalConfiguration.Configuration.Formatters.Add(new CustomXmlFormatter());
GlobalConfiguration.Configuration.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.XmlFormatter);
}
}
CustomXmlFormatter.cs:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Net.Http.Formatting;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using System.Xml.Serialization;
namespace Custom.Formatter
{
public class CustomXmlFormatter: MediaTypeFormatter
{
private UTF8Encoding encoder;
public CustomXmlFormatter()
{
SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/xml"));
SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/xml"));
encoder = new UTF8Encoding(false, true);
}
public override bool CanReadType(Type type)
{
if (type == (Type)null)
throw new ArgumentNullException("type");
//Type filtering
if (type == typeof(SendEmailMessageResponse) || type == typeof(SendSmsMessageResponse))
return true;
else
return false;
}
public override bool CanWriteType(Type type)
{
return true;
}
public override Task<object> ReadFromStreamAsync(Type type, Stream stream, HttpContent content, IFormatterLogger formatterLogger)
{
return Task.Factory.StartNew(() =>
{
using (var streamReader = new StreamReader(stream, encoder))
{
var serializer = new XmlSerializer(type);
return serializer.Deserialize(streamReader);
}
});
}
public override Task WriteToStreamAsync(Type type, object value, Stream stream, HttpContent content, TransportContext transportContext)
{
var serializer = new XmlSerializer(type);
return Task.Factory.StartNew(() =>
{
using (var streamWriter = new StreamWriter(stream, encoder))
{
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
serializer.Serialize(streamWriter, value, ns);
}
});
}
}
}
