I have used json code to call the controller/action method and convert the json format inside the project,everything worked in my localhost and my server which i had, but it was not working in some other server like US server, I don't know why it throws.
Is it cause Network or IIS confirguration or code issue? If Firewall or port issue means how to change their settings?
I have attached the code which I tried,
Class :
public class Jsonget
{
public static string jsonconvert(string url)
{
string currentsite = HttpContext.Current.Request.Url.Authority;
WebClient wc = new WebClient();
wc.Encoding = Encoding.UTF8;
wc.Encoding = UTF8Encoding.UTF8;
var uri = new Uri(HttpContext.Current.Request.Url.AbsoluteUri);
var requestType = uri.Scheme;
string jsonurl = requestType + "://" + currentsite + url;
var jsondata = wc.DownloadString(jsonurl);
string jsonresult = "{\"results\":" + jsondata.ToString() + "}";
return jsonresult;
}
}
Index.cshtml:
jsonurl = Url.Action("GetallPrograms", "Admin", new { Name = "testprogram" });
getjsonresult = Jsonget.jsonconvert(jsonurl);
Newtonsoft.Json.Linq.JObject programList = Newtonsoft.Json.Linq.JObject.Parse(getjsonresult);
foreach (var pgm in programList["results"])
{
<p>#((string)pgm["ProgramName"])</p>
}
AdminController:
public JsonResult GetallPrograms(string Name)
{
var programList = new List<CustomAttribute>();
BaseController bc = new BaseController();
try
{
var Exist_programs = (from n in bc.db.Programs where n.Name == Name select n).ToList();
foreach (var exist in Exist_programs)
{
programList.Add(new CustomAttribute
{
ProgramName = exist.ProgramName,
Id = exist.Id.ToString()
});
}
}
catch
{
programList.Add(new CustomAttribute
{
ProgramName ="",
Id = ""
});
}
return Json(programList, JsonRequestBehavior.AllowGet);
}
Please give suggestion to fix this?

How can i handle and how should i handle exception The remote server returned an error: (500) Internal Server Error?

The exception is happen most of the times but there are times it's working fine.
The exception is always the same
The remote server returned an error: (500) Internal Server Error.
Also the stacktrace is the same:
at System.Net.WebClient.DownloadDataInternal(Uri address, WebRequest& request)

at System.Net.WebClient.DownloadData(String address)
at SatelliteImages.ExtractImages.ExtractDateAndTime(String baseAddress) in D:\C-Sharp\SatelliteImages\SatelliteImages\SatelliteImages\ExtractImages.cs:line 120
Line 120 is:
var temp = wc.DownloadData("/en");
The method:
public void ExtractDateAndTime(string baseAddress)
{
try
{
var wc = new WebClient();
wc.BaseAddress = baseAddress;
HtmlDocument doc = new HtmlDocument();
var temp = wc.DownloadData("/en");
doc.Load(new MemoryStream(temp));
var secTokenScript = doc.DocumentNode.Descendants()
.Where(e =>
String.Compare(e.Name, "script", true) == 0 &&
String.Compare(e.ParentNode.Name, "div", true) == 0 &&
e.InnerText.Length > 0 &&
e.InnerText.Trim().StartsWith("var region")
).FirstOrDefault().InnerText;
var securityToken = secTokenScript;
securityToken = securityToken.Substring(0, securityToken.IndexOf("arrayImageTimes.push"));

var dates = securityToken.Trim().Split(new string[] { ";" }, StringSplitOptions.RemoveEmptyEntries);
var scriptDates = dates.Select(x => new ScriptDate { DateString = x });
foreach (var date in scriptDates)
{

}
}

}
}
}
countriescodes = new List<string>();
countriesnames = new List<string>();
DatesAndTimes = new List<string>();
imagesUrls = new List<string>();
this.Init();
}
}
When I use a breakpoint on the line:
string error = reader.ReadToEnd();
I see html content and in the content I see the text:
error occurred while processing your request. Return to the homepage of Sat24.com
What I want to do is somehow when the exception happen to start over again and try the download try the method ExtractDateAndTime.
I think using a timer some how and count back showing the user something like 30 seconds and try again. Will 30 seconds try will be consider as spam/flooding in the server site ?
This is the full class code but the exception is on this method ExtractDateAndTime.

What i want is in case of the exception happen to start over clean over again the whole class operation.
In Form1 i start the class operation first time once:
In top:
ExtractImages ei = new ExtractImages();
Then in constructor:
ei.Init();
The problem is this exception that sometimes happen.

You could go with something like Polly or the Transient Fault Handling Application Block to apply a retry strategy to your code.
Both packages provide multiple out-of-the-box components for various scenarios and you can always develop you own. Some of the included retry policies:
Incremental
Fixed interval
Exponential back-off
Retry
Retry for ever
Retry and wait
Wait and retry for ever

How to Format List in HttpResponseMessage in WEB API

Here, I want the list "User" as a response. But it contains Message also. I want the message to be printed only once. Currently it is printing user.count times.
for (int i = 0; i < user.Count; i++)
{
if (user[i].Message == "Success")
{
resp = new HttpResponseMessage { Content = new ObjectContent(typeof(List<GetUserList>), user, GlobalConfiguration.Configuration.Formatters.JsonFormatter) };
}
else
{
resp = new HttpResponseMessage { Content = new StringContent("[{\"Message\":\"" + user[i].Message + "\"}]", System.Text.Encoding.UTF8, "application/json") };
}
}
The result should be like this:
{
"message": " Successful",
"supervisorlist": [
{
" userID ": "654",
" forename ": "John"
},
{
" userID ": "655",
" forename ": "Jack"
}
]
}

example for Success
var responseObj = new { message = "Successful", supervisorlist = users };
resp = new HttpResponseMessage
{
Content = new StringContent(JsonConvert.SerializeObject(responseObj),
System.Text.Encoding.UTF8, "application/json")
};

bool includeMessage = users.Any(u => u.Message == "Success");
object content = null;
if(includeMessage) {
content = new { message = "Success", supervisorlist = users };
} else {
content = new { supervisorlist = users };
}
resp = new HttpResponseMessage {
Content = new StringContent(JsonConvert.SerializeObject(content), System.Text.Encoding.UTF8, "application/json")
};

Royal Mail Shipping API C#

I'm trying to integrate the Royal Mail SOAP API into my .NET Code. I have followed the advice here Consume WCF Royal Mail API in c# Console Application and here C# WCF Namespaces Move To Header & Use NS Prefix.
I have created a custom IClientMessageFormatter to be able to attach the namespaces to the beginning of the soap envelope, but I still can't seem to get this to work. I keep receiving the following error. Could not establish trust relationship for the SSL/TLS secure channel with authority 'api.royalmail.com', and the inner exception is: The remote certificate is invalid according to the validation procedure.
I am using Visual Studio 13 and .Net version 3.5, I've tried numerous other versions but with no further progress. When I debug I can see that the normal message been passed into the RoyalMailMessage but when it runs OnWriteStartEnvelope I can't see any changes to the _message object. I've created a trace to see what soap request is been sent.
I have sent my XML request to Royal Mail support who validate that the reason it is failing is due to the namespaces not been declared in the envelope and the missing prefixes.
RoyalMail.cs
internal class RoyalMail
{
private readonly X509Certificate2 _certificate;
private readonly Config _config;
public RoyalMail()
{
_config = new Config();
_config.LoadConfig();
// Load The SSL Certificate (Check The File Exists)

}

store.Open(OpenFlags.ReadWrite);
if (!store.Certificates.Contains(_certificate))
{

The error you are getting is basically because of the certificate.
Having said that, I think you should use the v2 of the API as although it is still awful, there are examples out there and you don't need to use a cert.
Rick Strahl has successfully changed the namespaces in the v2 version, see here https://weblog.west-wind.com/posts/2016/Apr/02/Custom-Message-Formatting-in-WCF-to-add-all-Namespaces-to-the-SOAP-Envelope .

There is one new Royal Mail Shipping API 2 available , after I've lost many hours try development the integration with Royal Mail I finally found a way. I'm sharing my project in the git.

C# Web API method returns 403 Forbidden

Solved!!! - See last edit.
In my MVC app I make calls out to a Web API service with HMAC Authentication Filterign. My Get (GetMultipleItemsRequest) works, but my Post does not. If I turn off HMAC authentication filtering all of them work. I'm not sure why the POSTS do not work, but the GETs do.
I make the GET call from my code like this (this one works):
var productsClient = new RestClient<Role>(System.Configuration.ConfigurationManager.AppSettings["WebApiUrl"],
"xxxxxxxxxxxxxxx", true);
var getManyResult = productsClient.GetMultipleItemsRequest("api/Role").Result;
I make the POST call from my code like this (this one only works when I turn off HMAC):
private RestClient<Profile> profileClient = new RestClient<Profile>(System.Configuration.ConfigurationManager.AppSettings["WebApiUrl"],
"xxxxxxxxxxxxxxx", true);
[HttpPost]
public ActionResult ProfileImport(IEnumerable<HttpPostedFileBase> files)
{
//...
var postResult = profileClient.PostRequest("api/Profile", newProfile).Result;
}
My RestClient builds like this:
public class RestClient<T> where T : class
{
//...
private void SetupClient(HttpClient client, string methodName, string apiUrl, T content = null)
{
const string secretTokenName = "SecretToken";
client.BaseAddress = new Uri(_baseAddress);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
if (_hmacSecret)
{
client.DefaultRequestHeaders.Date = DateTime.UtcNow;
var datePart = client.DefaultRequestHeaders.Date.Value.UtcDateTime.ToString(CultureInfo.InvariantCulture);
var fullUri = _baseAddress + apiUrl;
var contentMD5 = "";
if (content != null)
{
var json = new JavaScriptSerializer().Serialize(content);
contentMD5 = Hashing.GetHashMD5OfString(json); // <--- Javascript serialized version is hashed
}
var messageRepresentation =
methodName + "\n" +
contentMD5 + "\n" +
datePart + "\n" +
fullUri;
var sharedSecretValue = ConfigurationManager.AppSettings[_sharedSecretName];
var hmac = Hashing.GetHashHMACSHA256OfString(messageRepresentation, sharedSecretValue);
client.DefaultRequestHeaders.Add(secretTokenName, hmac);
}
else if (!string.IsNullOrWhiteSpace(_sharedSecretName))
{
var sharedSecretValue = ConfigurationManager.AppSettings[_sharedSecretName];
client.DefaultRequestHeaders.Add(secretTokenName, sharedSecretValue);
}
}
public async Task<T[]> GetMultipleItemsRequest(string apiUrl)
{
T[] result = null;
try
{
using (var client = new HttpClient())
{
SetupClient(client, "GET", apiUrl);
var response = await client.GetAsync(apiUrl).ConfigureAwait(false);
response.EnsureSuccessStatusCode();
await response.Content.ReadAsStringAsync().ContinueWith((Task<string> x) =>
{
if (x.IsFaulted)
throw x.Exception;
result = JsonConvert.DeserializeObject<T[]>(x.Result);
});
}
}
catch (HttpRequestException exception)
{
if (exception.Message.Contains("401 (Unauthorized)"))
{
}
else if (exception.Message.Contains("403 (Forbidden)"))
{
}
}
catch (Exception)
{
}
return result;
}
public async Task<T> PostRequest(string apiUrl, T postObject)
{
T result = null;
try
{
using (var client = new HttpClient())
{
SetupClient(client, "POST", apiUrl, postObject);
var response = await client.PostAsync(apiUrl, postObject, new JsonMediaTypeFormatter()).ConfigureAwait(false); //<--- not javascript formatted
response.EnsureSuccessStatusCode();
await response.Content.ReadAsStringAsync().ContinueWith((Task<string> x) =>
{
if (x.IsFaulted)
throw x.Exception;
result = JsonConvert.DeserializeObject<T>(x.Result);
});
}
}
catch (HttpRequestException exception)
{
if (exception.Message.Contains("401 (Unauthorized)"))
{
}
else if (exception.Message.Contains("403 (Forbidden)"))
{

catch (Exception)

return result;

My Web API Controller is defined like this:
[SecretAuthenticationFilter(SharedSecretName = "xxxxxxxxxxxxxxx", HmacSecret = true)]
public class ProfileController : ApiController
{
[HttpPost]
[ResponseType(typeof(Profile))]
public IHttpActionResult PostProfile(Profile Profile)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
GuidValue = Guid.NewGuid();
Resource res = new Resource();
res.ResourceId = GuidValue;
var data23 = Resourceservices.Insert(res);
Profile.ProfileId = data23.ResourceId;
_profileservices.Insert(Profile);
return CreatedAtRoute("DefaultApi", new { id = Profile.ProfileId }, Profile);
}
}
Here is some of what SecretAuthenticationFilter does:
//now try to read the content as string
string content = actionContext.Request.Content.ReadAsStringAsync().Result;
var contentMD5 = content == "" ? "" : Hashing.GetHashMD5OfString(content); //<-- Hashing the non-JavaScriptSerialized
var datePart = "";
var requestDate = DateTime.Now.AddDays(-2);
if (actionContext.Request.Headers.Date != null)
{
requestDate = actionContext.Request.Headers.Date.Value.UtcDateTime;
datePart = requestDate.ToString(CultureInfo.InvariantCulture);
}
var methodName = actionContext.Request.Method.Method;
var fullUri = actionContext.Request.RequestUri.ToString();
var messageRepresentation =
methodName + "\n" +
contentMD5 + "\n" +
datePart + "\n" +
fullUri;
var expectedValue = Hashing.GetHashHMACSHA256OfString(messageRepresentation, sharedSecretValue);
// Are the hmacs the same, and have we received it within +/- 5 mins (sending and
// receiving servers may not have exactly the same time)
if (messageSecretValue == expectedValue
&& requestDate > DateTime.UtcNow.AddMinutes(-5)
&& requestDate < DateTime.UtcNow.AddMinutes(5))
goodRequest = true;
Any idea why HMAC doesn't work for the POST?
EDIT:
When SecretAuthenticationFilter tries to compare the HMAC sent, with what it thinks the HMAC should be they don't match. The reason is the MD5Hash of the content doesn't match the MD5Hash of the received content. The RestClient hashes the content using a JavaScriptSerializer.Serialized version of the content, but then the PostRequest passes the object as JsonMediaTypeFormatted.
These two types don't get formatted the same. For instance, the JavaScriptSerializer give's us dates like this:
\"EnteredDate\":\"\/Date(1434642998639)\/\"
The passed content has dates like this:
\"EnteredDate\":\"2015-06-18T11:56:38.6390407-04:00\"
I guess I need the hash to use the same data that's passed, so the Filter on the other end can confirm it correctly. Thoughts?
EDIT:
Found the answer, I needed to change the SetupClient code from using this line:
var json = new JavaScriptSerializer().Serialize(content);
contentMD5 = Hashing.GetHashMD5OfString(json);
To using this:
var json = JsonConvert.SerializeObject(content);
contentMD5 = Hashing.GetHashMD5OfString(json);
Now the sent content (formatted via JSON) will match the hashed content.
I was not the person who wrote this code originally. :)
