使用ASP.NET WebAPI对POST请求进行XML模式验证

using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Xml;
using System.Xml.Schema;

[HttpPost]
public HttpResponseMessage ValidateXml([FromBody] string xmlContent)
{
    // 加载XML模式文件
    XmlSchemaSet schemaSet = new XmlSchemaSet();
    XmlSchema xmlSchema = XmlSchema.Read(new XmlTextReader("path/to/xsd/file.xsd"), null);
    schemaSet.Add(xmlSchema);

    // 验证XML文档
    XmlReaderSettings settings = new XmlReaderSettings();
    settings.Schemas = schemaSet;
    settings.ValidationType = ValidationType.Schema;
    settings.ValidationEventHandler += (sender, args) =>
    {
        ModelState.AddModelError("XmlValidation", args.Message);
    };

    using (XmlReader reader = XmlReader.Create(new StringReader(xmlContent), settings))
    {
        while (reader.Read()) { }
    }

    // 返回验证结果
    if (ModelState.IsValid)
    {
        return Request.CreateResponse(HttpStatusCode.OK, "XML文档符合模式");
    }
    else
    {
        return Request.CreateResponse(HttpStatusCode.BadRequest, ModelState);
    }
}
