Issue with sending XML to Web Api via http Post request
I would like to send the following XML document to my Web Api 2 controller; however, the [FromBody] parameter is always null.
Here is the request XML body:
Using Postman to send the request, is as follows :
POST /api/razorXmlRequest HTTP/1.1
Host: localhost:5000
Content-Type: application/xml
Cache-Control: no-cache
Postman-Token: 6ca91ebf-31e0-77f2-6f81-cb9993b69b1a
<razorInbound server="PortfolioExposureServer" request="lookupRiskPointRecord">
<caller>RazorClient</caller>
<responseMode>xml</responseMode>
<body>
<conditions>
<fromOffset>0</fromOffset>
<top>100</top>
<condition>
<keyPath>
<keyElement nodeOffset='1'>Currency</keyElement>
<keyElement nodeOffset='2'>ID</keyElement>
</keyPath>
<lookupValue>USD</lookupValue>
</condition>
</conditions>
</body>
</razorInbound>And the Web Api 2 controller :
NOTE: The param parameter is always null
I believe I need a proper class definition to correctly map the XML request, but I'm not sure how to construct it.
using System;
using System.Threading.Tasks;
using System.IO;
using System.Text;
using RazorServices;
using System.Net.Http;
using System.Web.Http;
using System.Xml.Linq;
using System.Net;
using System.Xml;
namespace RazorWebApi.Controllers
{
[Route("api/razorXmlRequest")]
public class RazorXmlRequestController : ApiController
{
public class RawXml {
public string RazorXml { get; set; }
}
[HttpPost]
public async Task<HttpResponseMessage> Post([FromBody]RawXml param )
{
HttpResponseMessage resp = new HttpResponseMessage(HttpStatusCode.OK);
// code omitted...
return resp;
}
}
}And by the way, we are currently getting around this issue by setting up a StreamReader object to pull from this.Request.Content; however in my unit test I need to send my xml as a parameter.
[HttpPost]
public async Task<HttpResponseMessage> Post() // [FromBody]RawXml param )
{
HttpResponseMessage resp = new HttpResponseMessage(HttpStatusCode.OK);
StreamReader sr = new StreamReader(await this.Request.Content.ReadAsStreamAsync(), Encoding.UTF8);
string xml = sr.ReadToEnd();
if (xml == null || xml.Length < 4)
{
throw new RazorServicesException("Invalid XML");
}
RazorSession cred = RzWebApi.Cred;
string reply = await RzWebApi.RazorSrv.xmlRequests.Request(cred, xml);
resp.Content = new StringContent(reply, System.Text.Encoding.UTF8, "text/plain");
return resp;
}Answer
Final solution was to change the Post param type to XElement:
[Route("api/razorXmlRequest")]
public class RazorXmlRequestController : ApiController
{
/// <summary>
/// Raw Razor request XML
/// </summary>
/// <returns>Razor reply message as text</returns>
[HttpPost]
public async Task<HttpResponseMessage> Post([FromBody]XElement xml)
{
HttpResponseMessage resp = new HttpResponseMessage(HttpStatusCode.OK);
RazorSession cred = RzWebApi.Cred;
string reply = await RzWebApi.RazorSrv.xmlRequests.Request(cred, xml);
resp.Content = new StringContent(reply, System.Text.Encoding.UTF8, "application/xml");
return resp;
}
}
This worked straight-away without even providing the XmlFormatter as the gentlemen had suggested above (@TusharJ, thank you anyway for your input).
