I need to read content of message from the request body in WCF REST service like -
SERVICE SIDE CODE
string request = Encoding.UTF8.GetString(OperationContext.Current.RequestContext.RequestMessage.GetBody<byte[]>());
But I am getting an error on the service side, no matter what I try:
Expecting element 'base64Binary' from namespace 'http://schemas.microsoft.com/2003/10/Serialization/'.. Encountered 'Element' with name 'Human', namespace 'http://numans.hr-xml.org/2007-04-15'.
and the service contract is defined as:
//[OperationContract(Name = "LoadMessages", IsOneWay = true)]
[WebInvoke(Method = "POST",
UriTemplate = "/LoadMessages",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Bare)]
[Description("Inbound Message")]
void LoadMessages();
and the implementation is as:
public void LoadMessages()
{
string content = string.Empty;
//var request = OperationContext.Current.RequestContext.RequestMessage.GetBody<FileState>();
string request = Encoding.UTF8.GetString(OperationContext.Current.RequestContext.RequestMessage.GetBody<byte[]>());
}
CLIENT SIDE CODE
Content that I'm sending is:
string jsonData = "{ \"categoryid\":\"" + file.CategoryId + "\",\"fileId\":\"" + file.FileId + "\" }";
I tried many options to send data from the client like:
var buffer = System.Text.Encoding.UTF8.GetBytes(jsonData);
var content = new ByteArrayContent(buffer);
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
and also tried this:
var content = new StringContent(jsonData, Encoding.UTF8, "application/json");
Posting request:
HttpResponseMessage executionResult = httpClient.PostAsync($"{url}/LoadMessages", content).Result;
I also tried serializing/de-serializing at client/server end, but that also is not working.
Can someone please suggest code samples what I can try that might work? Or point out what am I doing wrong.
A few more examples of what I tried with the JSON data :
var jsonData = JsonConvert.SerializeObject(data, Formatting.Indented);
var details = JObject.Parse(data);
Pasting my client side function for clarity:
HttpClient httpClient = new HttpClient(new HttpClientHandler());
HttpStatusCode statusCode = HttpStatusCode.OK;
string auditMessage = string.Empty;
using (httpClient)
{
var url = ConfigurationManager.AppSettings["APIURL"];
try
{
string jsonData = "{ \"categoryid\":\"" + file.CategoryId + "\",\"fileId\":\"" + file.FileId + "\" }";
//var jsonData = JsonConvert.SerializeObject(data, Formatting.Indented);
//var details = JObject.Parse(data);
//var content = new StringContent(jsonData, Encoding.UTF8, "application/json");
var buffer = System.Text.Encoding.UTF8.GetBytes(jsonData);
var content = new ByteArrayContent(buffer);
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
HttpResponseMessage executionResult = httpClient.PostAsync($"{url}/LoadMessages", content).Result;
statusCode = executionResult.StatusCode;
if (statusCode == HttpStatusCode.Accepted)
{
file.Status = "Success";
}
}
catch (Exception ex)
{
}
}
Here is my demo:
This is the interface document of the service:
This is the request:
class Program
{
static void Main(string[] args)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:8012/ServiceModelSamples/service/user");
request.Method = "POST";
request.ContentType = "application/json;charset=UTF-16";
string Json = "{\"Email\":\"123\",\"Name\":\"sdd\",\"Password\":\"sad\"}";
request.ContentLength = Encoding.UTF8.GetByteCount(Json);
Stream myRequestStream = request.GetRequestStream();
StreamWriter myStreamWriter = new StreamWriter(myRequestStream, Encoding.GetEncoding("gb2312"));
myStreamWriter.Write(Json);
myStreamWriter.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream myResponseStream = response.GetResponseStream();
//myResponseStream.ResponseSoapContext
StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));
string retString = myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
Console.WriteLine(retString);
Console.ReadKey();
}
}
Feel free to let me know if the problem persists.
UPDATE
Define the Test class:
[DataContract]
public class Test {
[DataMember]
public string categoryid { get; set; }
[DataMember]
public string fileId { get; set; }
}
the implementation is as:
public void LoadMessages(Test test)
{
Test dataObject = OperationContext.Current.RequestContext.RequestMessage.GetBody<Test>(new DataContractJsonSerializer(typeof(Test)));
Console.WriteLine(dataObject.categoryid);
}
I'm experimenting with a Xamarin app, which should access a .NET Core REST server.
I ran into this issue when switching to https; I can access the api from Chrome no problem, but if I try so from within my app, I get a System.Net.WebException saying
'Error: TrustFailure (A call to SSPI failed, see inner exception.)'.
I setup my server like this:
public static IWebHostBuilder CreateWebHostBuilder(string[] args)
{
var host = WebHost.CreateDefaultBuilder(args)
.UseUrls("https://*:5000")
.UseContentRoot(Directory.GetCurrentDirectory())
.UseStartup<Startup>();
return host as IWebHostBuilder;
}
and in my app, I do something like this:
public bool addUser(User user)
{
var request = WebRequest.Create("https://192.168.1.79:5000/api/users");
request.ContentType = "application/json";
request.Method = "POST";
try
{
var json = JsonConvert.SerializeObject(user);
var data = Encoding.UTF8.GetBytes(json);
using (var stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
return response.StatusCode == HttpStatusCode.Created;
}
}
catch(Exception ecx)
{
var what = ecx.Message;
return false;
}
}
Thanks so much for any help!

Wondering if its possible and/or supported to put/post an entire object to REST Webservice, as opposed to just some name/value pairs ?
If so, can a List of objects be put/post-ed as well ?
I figured it may be possible, since a GET request is able to return a List of objects, I'd like to do the "reverse" operation with the updated objects (and not send them one at a time, or worse, in individual pieces via name/value pairs) ?
I understand this is a very basic question, but the approach I've taken so far was to just try and code the PUT and get it working (which works if the PUT function has no arguments, like:
public class AObjectController : ApiController
{
public List<int[]> Put()
{
List<int[]> ret = new List<int[]>();
ret.Add(new int[] {-1, 1111});
ret.Add(new int[] {-2, 2222});
return ret;
}
If I specify a single object, or list of objects, I get exceptions:
public List<int[]> Put(AObject object) **CASE 1**
public List<int[]> Put(List<AObject> objects) **CASE 2**
{
List<int[]> ret = new List<int[]>();
ret.Add(new int[] { -1, 1111 });
ret.Add(new int[] { -2, 2222 });
return ret;
}
CASE 1: public List(int[]) Put(AObject object)
CASE 2: public List(int[]) Put(List(AObject) objects)
Heres the code on the client side that is making the call:
public int writeAll(List<T> data)
{
_sendBuffer =
JsonConvert.SerializeObject(
tabletData,
new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All }
);
byte[] b = StringHelper.GetBytes(_sendBuffer);
string url = ContructUrlRequest(null, null);
WebRequest request = WebRequest.Create(url);
request.Method = "PUT";
request.ContentType = "application/json";
request.ContentLength = b.Length;
request.Credentials = CredentialCache.DefaultCredentials;
((HttpWebRequest)request).UserAgent = "...";
//((HttpWebRequest)request).AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
using (Stream requestStream = request.GetRequestStream())
{
requestStream.Write(b, 0, b.Length);
requestStream.Flush();
requestStream.Close();
}
WebResponse response = request.GetResponse();
if (response == null)
{
return -1;
}
StreamReader sr = new StreamReader(response.GetResponseStream()); ;
_recieveBuffer = sr.ReadToEnd();
List<int[]> _resultData = JsonConvert.DeserializeObject<List<int[]>>(
_recieveBuffer,
new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All }
);
return data.Count;
}
Thank you.
Used the serialization write code from server on my client side and it worked
public int writeAll(List<AObject> aObjects)
{
string url = ContructUrlRequest(null, null);
WebRequest request = WebRequest.Create(url);
request.Method = WebRequestMethods.Http.Put;
request.ContentType = "application/json; charset=utf-8";
request.Credentials = CredentialCache.DefaultCredentials;
((HttpWebRequest)request).UserAgent = "going insane";
JsonSerializerSettings serializerSettings = new JsonSerializerSettings();
serializerSettings.TypeNameHandling = TypeNameHandling.Objects | TypeNameHandling.Arrays;
serializerSettings.Converters.Add(new IsoDateTimeConverter());
JsonSerializer serializer = JsonSerializer.Create(serializerSettings);
using (Stream requestStream = request.GetRequestStream())
{
using (StreamWriter streamWriter = new StreamWriter(requestStream, new UTF8Encoding(false, true)))
{
using (JsonTextWriter jsonTextWriter = new JsonTextWriter(streamWriter))
{
serializer.Serialize(jsonTextWriter, aObjects);
}
}
}
WebResponse response = request.GetResponse();
if (response == null)
{
Log.Info(FIDB.TAG_WSBUFFER, "WSBuffer.writeAll: response = NULL");
return -1;
}
StreamReader sr = new StreamReader(response.GetResponseStream());
_recieveBuffer = sr.ReadToEnd();
_resultData = JsonConvert.DeserializeObject<List<int[]>>(
_recieveBuffer,
new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All }
);
return tabletData.Count;
}
I have written one simple web service which get product list in JSONText which is string object
Web Service code is below
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.Services;
using System.Web.Script.Services;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;
/// <summary>
/// Summary description for JsonWebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class JsonWebService : System.Web.Services.WebService
{
public JsonWebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string GetProductsJson(string prefix)
{
List<Product> products = new List<Product>();
if (prefix.Trim().Equals(string.Empty, StringComparison.OrdinalIgnoreCase))
{
products = ProductFacade.GetAllProducts();
}
else
{
products = ProductFacade.GetProducts(prefix);
}
//yourobject is your actula object (may be collection) you want to serialize to json
DataContractJsonSerializer serializer = new DataContractJsonSerializer(products.GetType());
//create a memory stream
MemoryStream ms = new MemoryStream();
//serialize the object to memory stream
serializer.WriteObject(ms, products);
//convert the serizlized object to string
string jsonString = Encoding.Default.GetString(ms.ToArray());
//close the memory stream
ms.Close();
return jsonString;
}
}
now it give me resoponse like below :
{"d":"[{\"ProductID\":1,\"ProductName\":\"Product 1\"},{\"ProductID\":2,\"ProductName\":\"Product 2\"},{\"ProductID\":3,\"ProductName\":\"Product 3\"},{\"ProductID\":4,\"ProductName\":\"Product 4\"},{\"ProductID\":5,\"ProductName\":\"Product 5\"},{\"ProductID\":6,\"ProductName\":\"Product 6\"},{\"ProductID\":7,\"ProductName\":\"Product 7\"},{\"ProductID\":8,\"ProductName\":\"Product 8\"},{\"ProductID\":9,\"ProductName\":\"Product 9\"},{\"ProductID\":10,\"ProductName\":\"Product 10\"}]"}
But i am looking for below out put
[{"ProductID":1,"ProductName":"Product 1"},{"ProductID":2,"ProductName":"Product 2"},{"ProductID":3,"ProductName":"Product 3"},{"ProductID":4,"ProductName":"Product 4"},{"ProductID":5,"ProductName":"Product 5"},{"ProductID":6,"ProductName":"Product 6"},{"ProductID":7,"ProductName":"Product 7"},{"ProductID":8,"ProductName":"Product 8"},{"ProductID":9,"ProductName":"Product 9"},{"ProductID":10,"ProductName":"Product 10"}]
can any one tell me what is actual problem
Thanks
First there was a change with ASP.NET 3.5 for security reasons Microsoft added the "d" to the response. Below is a link from Dave Ward at the Encosia that talks about what your seeing:
A breaking change between versions of ASP.NET AJAX. He has several posts that talks about this that can help you further with processing JSON and ASP.NET
Actually, if you just remove the
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
from the method, and you return the jsonString that you serialized using the JavaScriptSerializer you will get exactelly the output that you were looking for.
Notice that u have double quotes beside ur array in your response.In this way u return json format not json object from ur web method.Json format is a string.Therefore u have to use json.parse() function in order to parse json string to json object.If u dont want to use parse fuction,u have to remove serialize in ur web method.Thus u get a json object.
