I am using following code to publish story on facebook:
FacebookWebClient facebookWebClient = new FacebookWebClient(UserSession.CurrentFacebookProfileAccessToken);
string URL="https://graph.facebook.com/me/tsstesting:start";
var parameters = new Dictionary<string, object>();
parameters["og:type"] = "tsstesting:myurl";
parameters["urlname"] = "http://on.fb.me/12rMxhV";
parameters["title"] = "QBSTab";
try
{
dynamic result = facebookWebClient.Post(URL, parameters); // again here should be your app name instead of "myapp"
JObject friendListJson = JObject.Parse(result.ToString());
string returval = friendListJson["id"].ToString();
return returval;
}
catch (Exception e)
{
return e.Message;
}
It gives me exception Object at URL 'https://www.facebook.com/' of type 'website' is invalid because the given value 'www' for property 'og:locale:alternate' could not be parsed as type 'enum'.
What I am missing here?

My machine is registered as trusted host on tableau server, still i am getting -1 when i request for token.
How do i Pass a Map of Key Value pairs to a GET REST API,
Here is the call to the resource .. I am getting a method not allowed
String queryMap= String.format("{'softwareversion':'%s','peril':'%s','analysistype':'%s', 'region':'%s'}", "HD18", "Flood", "EP", "USFL");
String url = String.format("http://localhost:%d/templates/modelprofile?queryMap=%s", API_APPLICATION_RULE.getLocalPort(),queryMap);
Response response = ClientBuilder.newClient()
.target(url)
.request()
.header("Authorization", getToken())
.get();
I have the resource as below
#GET
#Path("/{templateType}")
#Timed
#Produces(MediaType.APPLICATION_JSON)
#ApiOperation(value = "Get templates based on peril/region,version and type",
httpMethod = ApiConstants.GET)
#ApiResponses(value = {
#ApiResponse(code = ApiConstants.INT_200,
message = "TemplateReader was retrieved successfully from the database."),
#ApiResponse(code = ApiConstants.INT_400,
message = "Bad request (wrong or missing inputs)"),
#ApiResponse(code = ApiConstants.INT_500,
message = ApiConstants.INTERNAL_SERVER_ERROR)
})
public Template getTemplate(#ApiParam(hidden = true) #Auth User user,
#ApiParam(name = "templateType", value = "templateType")
#PathParam("templateType") String templateType,
#ApiParam(name = "queryMap", value = "queryMap")
#RequestParameters Map<String,String> queryMap
) throws ApiException
You can pass it using request parameter as below.
#RequestMapping(name = "/url/", method = RequestMethod.GET)
public void method_name(#RequestParam(name = "map_name")Map<String, Object> requestMap){
//Process map and perform your logic
}
I'm trying to post a file in a json object to an external rest api over https. I have confirmed the json object is formatted correctly, do I have to do anything special to post to a rest api over https? I'm using the answer found over here as a guide: How to post JSON to the server?
private static void PostDatatoFTP(string FileName,
string fileString, string centerCode, string fileType) {
try {
byte[] plainTextBytes = Encoding.ASCII.GetBytes(fileString);
string base64File = Convert.ToBase64String(plainTextBytes);
FileInfo fileInfo = new FileInfo {
FileData = base64File,
FileName = FileName,
FileType = fileType,
FileVersion = _fileVersion
};
FileInfo[] transmitFileInfo = new FileInfo[1];
transmitFileInfo[0] = fileInfo;
Json jsonObject = new Json {
RequestType = _RequestType,
APIVersion = _apiVersion,
SubmissionId = Guid.NewGuid().ToString(),
UserId = _ftpUsername,
Password = _ftpPassword,
Vendor = _vendor,
CenterCode = centerCode,
FileInfo = transmitFileInfo
};
var json = JsonConvert.SerializeObject(jsonObject);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(_uploadPath);
request.Method = "POST";
request.ContentType = "application/json";
using (var streamWriter = new StreamWriter(request.GetRequestStream())) {
streamWriter.Write(json);
}
var httpResponse = (HttpWebResponse)request.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream() ?? throw new InvalidOperationException())) {
var result = streamReader.ReadToEnd();
Console.WriteLine(result);
}
}
catch (WebException e) {
Console.WriteLine(e.Message);
String status = ((HttpWebResponse)e.Response).StatusDescription;
Console.WriteLine(status);
}
catch (Exception ex) {
Console.WriteLine(ex.Message);
}

I'm trying out the facebook api. I'm getting this error that i'm not authorized to perform this action. I have accepted all the pop-ups that came when i run the program. Anyone got a quick soulution for this?
sing Facebook;
public void CheckAutorization()
{
string app_Id = "xxxxxxxxxxxxxxx";
string app_secret = "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy";
string scope = "publish_stream, manage_pages";
if (Request["code"] == null)
{
Response.Redirect(string.Format(
"https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}",
app_Id, Request.Url.AbsoluteUri, scope));
}
else
{
Dictionary<string, string> tokens = new Dictionary<string, string>();
string url = string.Format("https://graph.facebook.com/oauth/access_token?client_id={0}&redirect_uri={1}&scope={2}&code={3}&client_secret={4}",
app_Id, Request.Url.AbsoluteUri, scope, Request["code"].ToString(), app_secret);
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);
client.Post("/me/feed", new { message = "Is there anyone out there? :) Can i get a whoop whoop" });
}
}
}
}
Had to change the scope string scope = "publish_stream, manage_pages" to string scope = "publish_stream, publish_actions";
I am having problem posting the photo to the facebook.Anybody know how to it. Please help. Thanks.
FacebookClient fb = new FacebookClient(App.AccessToken);
fb.PostCompleted += (o, e) =>
{
if (e.Error != null)
{
Dispatcher.BeginInvoke(() => MessageBox.Show(e.Error.Message));
return;
}
var result = (IDictionary<string, object>)e.GetResultData();
Dispatcher.BeginInvoke(() =>
{
MessageBox.Show("Success post message to the wall.");
// reset the selections after the post action has successfully concluded
tbmessage.Text = "";
});
};
var parameters = new Dictionary<string, object>();
parameters["name"] = tbmessage.Text;
dynamic res = fb.PostTaskAsync("me/photos", parameters);
In the parameters list, you have to provide the image source by either of the following:
url : a valid url to the image
source: iamge data
[Code]
[HttpPost]
public ActionResult PostPhotoOnWall(HttpPostedFileBase file)
{
var filename = Path.GetFileName(file.FileName);
StreamResourceInfo sri = null;
Uri jpegUri = new Uri(filename, UriKind.Relative);
sri = Application.GetResourceStream(jpegUri);
byte[] imageData = new byte[sri.Stream.Length];
sri.Stream.Read(imageData, 0, System.Convert.ToInt32(sri.Stream.Length));
var client = new FacebookClient();
// Post to user's wall
var postparameters = new Dictionary<string, object>();
var media = new FacebookMediaObject
{
FileName = filename,
ContentType = "image/jpeg"
};
media.SetValue(imageData);
postparameters["source"] = media;
postparameters["access_token"] = Session["access_token"].ToString();
var result = client.Post("/me/photos", postparameters);
return View("PostPhoto");
}
