How to do a Post using WebRequest from a Class Library?

I want to call to a API using a class library.
Here is the way they need us to send the post request
Or
To achecive this I use this code
public class Keey
{
public string username { get; set; }
public string passward { get; set; }
public string src { get; set; }
public string dst { get; set; }
public string msg { get; set; }
public string dr { get; set; }
}
public void SendSms(string phoneNo, string SMS)
{
Keey account = new Keey
{
username = "*****",
passward = "*********",
src = "test.com",
dst = phoneNo,
msg = SMS,
dr = "1",
};
WebRequest request = WebRequest.Create("http://testserver.com ");
// Set the Method property of the request to POST.
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = SMS.Length;
CredentialCache.DefaultNetworkCredentials.UserName = account.username;
CredentialCache.DefaultNetworkCredentials.Password = account.passward;
request.Credentials = CredentialCache.DefaultNetworkCredentials;
WebResponse response = request.GetResponse();
}
But I dont know where to add those port,src,dst,msg etc... Please help me
Code is in C#

That is depend on your Web-Api Service. for what input parameter needed.
There are several ways to perform POST requests:
HttpWebRequest (not recommended for new work)
using System.Net;
using System.Text; // For class Encoding
using System.IO; // For StreamReader
var request = (HttpWebRequest)WebRequest.Create("http://testserver.com/test.aspx");
//your data should place in here
var postData = "thing1=" + Uri.EscapeDataString("hello");
postData += "&thing2=" + Uri.EscapeDataString("world");
var data = Encoding.ASCII.GetBytes(postData);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
using (var stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
recommended way to get this work:
using System.Net.Http;
private static readonly HttpClient client = new HttpClient();
POST
var values = new Dictionary<string, string>
{
{ "thing1", "hello" },
{ "thing2", "world" }
};
var content = new FormUrlEncodedContent(values);
var response = await client.PostAsync("http://testserver.com/test.aspx", content);
var responseString = await response.Content.ReadAsStringAsync();

Google vision connection to API without external google DLL

How to connect to google cloud vision without using external dlls?

First, you will have to generate JSON request, simple example:
Request req = new Request();
req.addFeature("DOCUMENT_TEXT_DETECTION"); //Add here all the feature types
req.Image.content = Convert.ToBase64String(qq);//qq is a byte[]
Requests reqList = new Requests(req);
json = JsonConvert.SerializeObject(reqList);
Secondly, you need to post simple HTTP request:
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://vision.googleapis.com/v1/images:annotate?key="PLACE_YOURKEY_HERE"");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Write(json);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
response = streamReader.ReadToEnd();
}
Memebers of the JSON classes (The methods should be implemented):
class Requests
{
public List<Request> Request { get; set; }
}
class Request
{
public Image1 Image { get; set; }
public List<Feature> Features { get; set; }
}
public class Feature
{
public string Type { get; set; }
}
public class Image1
{
public string content { get; set; }
}

Calling WebApi with complex object parameter using WebClient

I need to call a WebApi using WebClient where have to pass an object as parameter. I have my WebApi method as similar to bellow code:
example URI: localhost:8080/Api/DocRepoApi/PostDoc
[HttpPost]
public string PostDoc (DocRepoViewModel docRepo)
{
return string.enpty;
}
and then DocRepoViewModel is:
public class DocRepoViewModel
{
public string Roles { get; set; }
public string CategoryName { get; set; }
public List<AttachmentViewModel> AttachmentInfo { get; set; }
}
AttachmentViewModel is:
public class AttachmentViewModel
{
public string AttachmentName { get; set; }
public byte[] AttachmentBytes { get; set; }
public string AttachmentType { get; set; }
}
New I need to call PostDoc method from my MVC controller (not javascript ajax). How can I pass this specific parameter that I can make the call and get all data in my WebApi method. Can we do it by WebClient? Or there are better way. Please help.

You could use the PostAsJsonAsync method as follows:
static async Task RunAsync()
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("localhost:8080/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
// HTTP POST
var docViewModel = new DocRepoViewModel() { CategoryName = "Foo", Roles= "role1,role2" };
var attachmentInfo = new List<AttachmentViewModel>() { AttachmentName = "Bar", AttachmentType = "Baz", AttachmentBytes = File.ReadAllBytes("c:\test.txt" };
docViewModel.AttachmentInfo = attachmentInfo;
response = await client.PostAsJsonAsync("DocRepoApi/PostDoc", docViewModel);
if (response.IsSuccessStatusCode)
{
// do stuff
}
}
}
Asp .net reference

Check out following code.
string url = "Your Url";
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.KeepAlive = false;
request.ContentType = "application/json";
request.Method = "POST";
var entity = new Entity(); //your custom object.
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(JsonConvert.SerializeObject(entity));
request.ContentLength = bytes.Length;
Stream data = request.GetRequestStream();
data.Write(bytes, 0, bytes.Length);
data.Close();
using (WebResponse response = request.GetResponse())
{
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
string message = reader.ReadToEnd();
var responseReuslt = JsonConvert.Deserialize<YourDataContract>(message);
}
}

Does anyone have an example of calling a Marketo Rest API from .net/C#.
I am particularly interested in the oauth authentication piece.
http://developers.marketo.com/documentation/rest/authentication/
I plan to call this endpoint
http://developers.marketo.com/documentation/rest/get-multiple-leads-by-list-id/
I cannot find any example out there on the interweb.

I was able to code up a solution for calling a Marketo Rest API and do the OAuth. Below is a how-to
The below code shows the basics, but needs clean up, logging and error handling to be production worthy.
You need to get the Rest api URL's for your Marketo instance. To do this, log into marketo, and navigate to Admin\Integration\Web Services, and use the URLs in the Rest API Section.
You need to get your user id and secret from marketo - navigate to Admin\Integration\Launch Pont. View the details of your Rest Service to get id and secret. If you don't have a Service, then follow these instructions http://developers.marketo.com/documentation/rest/custom-service/.
Finally, you need your list id for the list of leads you want to get. You can get this by navigating to your list and copying the numeric portion of the id out of the url. Example: https://XXXXX.marketo.com/#ST1194B2 —> List ID = 1194
private void GetListLeads()
{
string token = GetToken().Result;
string listID = "XXXX"; // Get from Marketo UI
LeadListResponse leadListResponse = GetListItems(token, listID).Result;
//TODO: do something with your list of leads
}
private async Task<string> GetToken()
{
string clientID = "XXXXXX"; // Get from Marketo UI
string clientSecret = "XXXXXX"; // Get from Marketo UI
string url = String.Format("https://XXXXXX.mktorest.com/identity/oauth/token?grant_type=client_credentials&client_id={0}&client_secret={1}",clientID, clientSecret ); // Get from Marketo UI
var fullUri = new Uri(url, UriKind.Absolute);
TokenResponse tokenResponse = new TokenResponse();
using (var client = new HttpClient())
{
HttpResponseMessage response = await client.GetAsync(fullUri);
if (response.IsSuccessStatusCode)
{
tokenResponse = await response.Content.ReadAsAsync<TokenResponse>();
}
else
{
if (response.StatusCode == HttpStatusCode.Forbidden)
throw new AuthenticationException("Invalid username/password combination.");
else
throw new ApplicationException("Not able to get token");
}
}
return tokenResponse.access_token;
}
private async Task<LeadListResponse> GetListItems(string token, string listID)
{
string url = String.Format("https://XXXXXX.mktorest.com/rest/v1/list/{0}/leads.json?access_token={1}", listID, token);// Get from Marketo UI
var fullUri = new Uri(url, UriKind.Absolute);
LeadListResponse leadListResponse = new LeadListResponse();
using (var client = new HttpClient())
{
HttpResponseMessage response = await client.GetAsync(fullUri);
if (response.IsSuccessStatusCode)
{
leadListResponse = await response.Content.ReadAsAsync<LeadListResponse>();
}
else
{
if (response.StatusCode == HttpStatusCode.Forbidden)
throw new AuthenticationException("Invalid username/password combination.");
else
throw new ApplicationException("Not able to get token");
}
}
return leadListResponse;
}
private class TokenResponse
{
public string access_token { get; set; }
public int expires_in { get; set; }
}
private class LeadListResponse
{
public string requestId { get; set; }
public bool success { get; set; }
public string nextPageToken { get; set; }
public Lead[] result { get; set; }

How to use "like" feature in facebook c# sdk 5.4.1?

in facebook developers site it seems pretty easy.just make a HTTP POST to POST_ID/likes(i got the post i.d).
in c# sdk v.5.4.1 there is a POST method but i can't figure out how to use it and make the right call.

Look at the face book API documentation..here http://developers.facebook.com/
var fb = new FacebookClient("my token");
dynamic parameters = new ExpandoObject();
parameters.message = "the publish msg";
dynamic result = fb.Post("/me/feed", parameters);
var id = result.id;
var res = fb.Post("/" + id + "/likes");

I was having the same issue so I tried few things & this worked for me
var token = "[your access token]";
var fb = new Facebook.FacebookClient(token);
var postId = "173213306032925_745288855492031"; //replace this with your big id which comprises of [userid]_[postid]
Console.WriteLine(fb.Post(id+"/likes", null).ToString()); // should print 'True'
Console.WriteLine(fb.Get("173213306032925_745288855492031/likes").ToString()); //should give you details

public void FacebookLike(AppConnect appconnect )
{
try
{
Dictionary<string, string> tokens = new Dictionary<string, string>();
string fb_exchange = appconnect.UserToken;
string url =
string.Format("https://graph.facebook.com/oauth/access_token?client_id={0}&grant_type=fb_exchange_token&fb_exchange_token={3}&redirect_uri=https://www.facebook.com/connect/login_success.html&scope={1}&client_secret={2}",
appconnect.AppID, appconnect.ExtendedPermissions, appconnect.AppSecret, fb_exchange);
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
string vals = reader.ReadToEnd();
foreach (string token in vals.Split('&'))
{
//meh.aspx?token1=steve&token2=jake&...
tokens.Add(token.Substring(0, token.IndexOf("=")),
token.Substring(token.IndexOf("=") + 1, token.Length - token.IndexOf("=") - 1));
}
}
string access_token = tokens["access_token"];
var client = new FacebookClient(access_token);
dynamic parameters = new ExpandoObject(); parameters.idobject = "";
client.Post("/" + appconnect.AppID.ToString() + "_" + appconnect.PostID.ToString() + "/Likes", parameters);
// MessageBox.Show("....... Done ..........");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message +"\n"+ex.InnerException);
}
}
