I have read the following post Post 1 and followed ak7's answer to get the url of fb image, but when i browse to the url, it shows a photo with grey background and a question mark. Then i tried to follow the Second post Mike Troinfo's answer and added picture as a parameter to query string, but the info variable doesn't have any parameter corresponding to image. Kindly help me in figuring out a solution to get Users DP from facebook and store it in database
var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
WebResponse response = null;
string pictureUrl = string.Empty;
try
{
WebRequest request = WebRequest.Create(string.Format("https://graph.facebook.com/{0}/picture?type=large&redirect", loginInfo.email));
response = request.GetResponse();
pictureUrl = response.ResponseUri.ToString();
}
Before getting picture you have get access token of an user. Then you hit that url to get picture. See this link first.
May be this link help you to get authentication token.
And last of all you have to hit url like that.
https://graph.facebook.com/me/picture?redirect&access_token=CAACEdEose0cBACwZBfdwRTNjsxu1HRxyhQ78lIKGonbKaNRidTtM9QjiwuVuD6DzXsNL1qLGkc1P3sHFnElQ287I1VUBfamvdV0pfBs8dDgbOShqRh2UuviXyv4ZAZAcEEeqlZCKb39nGuTZAjssXCKhS8NZBXun9KfWwZCV29s32K37ajnYIOBelHh3gZCaJsixwXkhPXiQ5ZA2MY2flK4sz
using this you will get a json
{
"data": {
"is_silhouette": true,
"url": "https://scontent.xx.fbcdn.net/hprofile-xfa1/v/t1.0-1/s200x200/10354686_10150004552801856_220367501106153455_n.jpg?_nc_eui=ARhjdKn0xJ2BpM9I6X_JD0UDCnmaSk6REHSU6yD01EeYw9avdnIb6dqiVr74&oh=3f560f9bf95ca602bb19c2d7b8870e1a&oe=57869A50"
}
}
Then you save the image from that url. There are lots of technique to save image from url.
{
byte [] data = webClient.DownloadData("https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xpf1/v/t34.0-12/10555140_10201501435212873_1318258071_n.jpg?oh=97ebc03895b7acee9aebbde7d6b002bf&oe=53C9ABB0&__gda__=1405685729_110e04e71d9");
using (MemoryStream mem = new MemoryStream(data))
{
using (var yourImage = Image.FromStream(mem))
{
// If you want it as Png
yourImage.Save("path_to_your_file.png", ImageFormat.Png) ;
// If you want it as Jpeg
yourImage.Save("path_to_your_file.jpg", ImageFormat.Jpeg) ;
}
}
}

Custom Search UI will be populated when user selects Complex asset in the Advance search screen drop down(apart from Folders,Contents) where 12 fields will be displayed .So when user clicks search button ,need to read those values and redirect to the alfresco repo files(org/alfresco/slingshot/search/search.get.js).We have already customized these files(search.get.js,search.lib.js) existed in the repository to suit out logic and working fine in 4.2.2;As we are migrating to 511,so we need to change this logic in customized faceted-search.get.js to read these values.How to write this logic in customized facted-search.get.js?
It's not actually possible to read those URL hash attributes in the faceted-search.get.js file because the JavaScript controller of the WebScript does not have access to that part of the URL (it only has information about the URL and the request parameters, not the hash parameters).
The hash parameters are actually handled on the client-side by the AlfSearchList widget.
Maybe you could explain what you're trying to achieve so that I can suggest an alternative - i.e. the end goal for the user, not the specifics of the coding you're trying to achieve.
We will be reading the querystring values something like below in the .get.js file.
function getNodeRef(){
var queryString = page.url.getQueryString();
var nodeRef = "NOT FOUND";
var stringArray = queryString.split("&");
for (var t = 0; t < stringArray.length; t++) {
if (stringArray[t].indexOf('nodeRef=') > -1) {
nodeRef = stringArray[t].split('=')[1];
break;
}
}
if (nodeRef !== "NOT FOUND") {
nodeRef = nodeRef.replace("://", "/");
return nodeRef;
}
else {
throw new Error("Node Reference is not found.");
}
}
It may be help you and we will wait for Dave Drapper suggestion also.
I have Image Url in my Database and i want to check whether the URL is responsive or not in the browser .
please Help me .
For Example :
http://images.jactravel.co.uk/6008_1_1.jpg
or
http://images.jactravel.co.uk/6049_2_4.jpg
now how can i check automatically this url is responsive or not
I assume that by responsive you mean whether you can get a response when you call a specific URL or not.
To do that without actually downloading the content, you can use the HttpClient.GetAsync(string,HttpCompletionOption) with an HttpCompletionOption of ResponseHeadersRead. This will make GetAsync return immediately with a status code (eg 200, 404 or 500) without waiting to download the entire content, eg:
using (var client = new HttpClient())
{
using(var response = await client.GetAsync("http://mysite/myimage.jpg",
HttpCompletionOption.ResponseHeadersRead))
{
if (response.IsSuccessStatusCode)
{
//The URL is good
}
}
}
To actually read the content, you need to access one of the Read methods of the response's Content property. For example, you can use the CopyToAsync to copy the content to a file stream, or use ReadAsByteArrayAsync to read the content as a byte array, eg:
var buffer=await response.Content.ReadAsByteArrayAsync();
As of today we are getting an error when we try to update an event using Google Calendar V3 API.
Here is our code:
string certificateFile = getCertificateFile();
string certificatePassword = getCertificatePassword();
string serviceAccountEmail = getServiceAccountEmail();
X509Certificate2 certificate = new X509Certificate2(AppDomain.CurrentDomain.BaseDirectory + "certs//" + certificateFile, certificatePassword, X509KeyStorageFlags.Exportable);
ServiceAccountCredential credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = new[] { Google.Apis.Calendar.v3.CalendarService.Scope.Calendar },
User = user
}.FromCertificate(certificate));
Google.Apis.Calendar.v3.CalendarService service = new Google.Apis.Calendar.v3.CalendarService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "Test",
});
try
{
Event evv = service.Events.Get(user, "6ebr4dp452m453n468movuntag").Execute();
EventsResource.UpdateRequest ur = new EventsResource.UpdateRequest(service, evv, user, evv.Id);
ur.Execute();
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
The Error message is " The specified value is not a valid quoted string. "
This is basic code that always works. We can still query and insert Events. For some reason updates have just stopped working?
Anybody else getting this?
I found what is the problem: Google API's ETag functionality seems to be broken.
To get around the issue I had to download the source code of the .NET Google API client libraries from google-api-dotnet-client Downloads and commented the call to the method AddETag() on line 189 of ClientServiceRequest.cs; that method adds the If-Match ETag header that's currently causing the issues. This file is in the GoogleApis project.
public HttpRequestMessage CreateRequest(Nullable<bool> overrideGZipEnabled = null)
{
var builder = CreateBuilder();
var request = builder.CreateRequest();
object body = GetBody();
request.SetRequestSerailizedContent(service, body, overrideGZipEnabled.HasValue
? overrideGZipEnabled.Value : service.GZipEnabled);
//AddETag(request);
return request;
}
See Protocol Reference: Updating Entries for more information on how Google API's use ETags and the If-Match header.
The problem in the Calendar API was fixed so no need to use this workaround!
Please don't use the above suggestion. Although it works, it will actually eliminate an important feature of etag in the library. A better solution is available at: https://codereview.appspot.com/96320045/
Thanks diegog for your work-around, I'm pretty sure it helped several users who were stuck today.
I have a Debugging Official Account with WeChat. I have entered my public URL and Token into the field provided http://admin.wechat.com/debug/sandbox and also attempted debugging the request with http://admin.wechat.com/debug/
My ASP.Net [.Net4.5] Web API application's POST Method looks like the following :
public HttpResponseMessage PostMessage([FromBody]Strikemedia.Api.WeChat.TextMessage value)
{
if (value == null)
{
var richMediaMessage = new RichMediaMessage();
richMediaMessage.touser = value.FromuserName;
//Create Article
var item = new Article()
{
title = "Didn't receive anything back",
description = "Mind entering 'test'",
picurl = "URL",
url = "URL"
};
var articles = new List<Article>();
articles.Add(item);
richMediaMessage.articles = articles;
richMediaMessage.articleCount = articles.Count;
return Request.CreateResponse(HttpStatusCode.OK, richMediaMessage, "application/json");
}
var exploded = value.Content.Split(' ')[0];
var richMedia = new RichMediaMessage();
richMedia.touser = value.FromuserName;
//Create Article
var article = new Article() {
title = response.KeywordDescription,
description = response.Response,
picurl = "URL",
url = "URL"
};
var _articles = new List<Article>();
_articles.Add(article);
richMedia.articles = _articles;
richMedia.articleCount = _articles.Count;
//Return response
var resp = Request.CreateResponse(HttpStatusCode.OK, richMedia, "application/json");
//resp.RequestMessage.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");
return resp;
}
It needs to respond with a RichMessageType in JSON format and is received in XML format
Am i missing something or have i overlooked something?
Can you confirm that you have submitted the URL and token into admin.wechat.com and that the URL and token was accepted?
Also note you get XML and you respond with XML no json response.
Have you had a look at: http://youtu.be/kB20Zf51QWU
And then this
http://youtu.be/_2FSzD2B2F0
This is the documentation for the XML can be found when you google "wechat guide to message api"
So if you still not receiving a success message when submitting your app on admin.wechat.com then you can send me your test URL here. To find this URL check your access logs to see exactly what URL wechat is calling. Then post it here. Please note that when you hit the URL as wechat will you should only see the "echostr" printed on the screen (when viewing the source in your browser). No XML no HTML just the echostr.
Also make sure there are no spaces or newlines after or before the "echostr". When you view the source it should only be one line which is the echostr GET param's value.
The XML response only comes in later when you actually start responding to messages from users. For now Wechat is just confirming if your security is setup correctly.
Also note if your server is load balanced you will have to skip the signature validation and build your own validation when a echostr GET parameter gets passed through and only echo the "echostr" param to screen.
I need to upload a file to my server. I have no prior knowledge to server side programming and need some advice I can understand. I have my file (JPEG Image) in a byte array in my Windows Phone app. I now need to upload it to my server. I currently have a sample that uses HttpWebRequest with post, but I do not know how to handle the data in that post from the asp page. If you could explain how to do this it would be great, but I am open to any alternatives, providing they can be used with Windows Server.
The code I am currently using: ('b' is the byte array for the file)
var uri = "http://www.masonbogert.info/mcode/default.aspx";
var request = HttpWebRequest.Create(uri);
request.Method = "POST";
request.ContentType = "image/jpeg"; // Change to whatever you're uploading.
request.BeginGetRequestStream((result1) =>
{
using (Stream stream = request.EndGetRequestStream(result1))
{
stream.Write(b, 0, b.Length);
}
request.BeginGetResponse((result2) =>
{
var response = request.EndGetResponse(result2);
// Optionally handle the response.
var responseStream = response.GetResponseStream();
Dispatcher.BeginInvoke(new readstreamdelegate(readstream), responseStream);
}, null);
}, null);
Remember, when it comes to ASP and any other server side programming I have no prior knowledge, so please explain!
You can try to use the "WebClient" class for getting it. More information you can get there: "http://msdn.microsoft.com/en-us/library/system.net.webclient(v=vs.80).aspx".
