I m using Given below code to post the tweet on twitter. But when we upload it on the server then special character (!,:,$ etc) tweets not published on twitter. this code is working fine in the local system
string key = "";
string secret = "";
string token="";
string tokenSecret="";
try
{
string localFilename = HttpContext.Current.Server.MapPath("../images/").ToString();
using (WebClient client = new WebClient())
{
client.DownloadFile(imagePath, localFilename);
}
var service = new TweetSharp.TwitterService(key, secret);
service.AuthenticateWith(token, tokenSecret);
// Tweet wtih image
if (imagePath.Length > 0)
{
using (var stream = new FileStream(localFilename, FileMode.Open))
{
var result = service.SendTweetWithMedia(new SendTweetWithMediaOptions
{
Status = message,
Images = new Dictionary<string, Stream> { { "name", stream } }
});
}
}
else // just message
{
var result = service.SendTweet(new SendTweetOptions
{
Status = HttpUtility.UrlEncode(message)
});
}
}
catch (Exception ex)
{
throw ex;
}
The statuses/update_with_media API endpoint is actually deprecated by Twitter and shouldn't be used (https://dev.twitter.com/rest/reference/post/statuses/update_with_media).
TweetSharp also has some issues with using this method when the tweet contains both a 'special character' AND an image (works fine with either, but not both). I don't know why and I haven't been able to fix it, it's something to do with the OAuth signature I'm pretty sure.
As a solution I suggest you use TweetMoaSharp (a fork of TweetSharp). It has been updated to support the new Twitter API's for handling media in tweets, and it will work in this situation if you use the new stuff.
Basically you upload each media item using a new UploadMedia method, and that will return you a 'media id'. You then use the normal 'SendTweet' method and provide a list of the media ids to it along with the other status details. Twitter will attach the media to the tweet when it is posted, and it will work when there are both special characters and images.
In addition to TweetMoaSharp you can use Tweetinvi with the following code:
var binary = File.ReadAllBytes(#"C:\videos\image.jpg");
var media = Upload.UploadMedia(binary);
var tweet = Tweet.PublishTweet("hello", new PublishTweetOptionalParameters
{
Medias = {media}
});

I'm trying to scrape some data from aliexpress using c# and html-agility-pack.
Usually, the xpath of some element looks like this :
/html/body/div[7]/div[2]/div[4]/div/div/div[2]/div[1]/div[2]/div/div[1]/a
But when i try to copy the xpath of an element in aliexpress it looks like this :
//*[#id="node-gallery"]/div[4]/div/div/ul/li[1]/div[1]/div[1]/a
and then the list of nodes return null and the program can't make any progress.
var html = #"https://best.aliexpress.com/?lan=en";
HtmlWeb web = new HtmlWeb();
var htmlDoc = web.Load(html);
var nodes = htmlDoc.DocumentNode.SelectNodes("//*[#id]/div/div[2]/div/div[2]/dl//dd/div/div[2]/ul/li//a");
if (nodes.Count <= 0)
{
Console.WriteLine("nothing found");
}
else
{
foreach (HtmlNode n in nodes)
{
Console.WriteLine(n.Attributes);
}
}
Console.ReadKey();
Indeed when you hover over those items an API request is made. You can probably find the detail in one of the source files however looking at the first 2 in the network tab they have the following pattern (url decoded):
https://best.aliexpress.com/api/load_ams_path.do?path=aliexpress.com/common/#langField/ru/c-women-content.htm
https://best.aliexpress.com/api/load_ams_path.do?path=aliexpress.com/common/#langField/ru/c-men-content.htm
I suspect the others follow suit.
You can make requests to these endpoints to get the html you can then retrieve you desired content from. To get the href for the xpath element matched in browser by your xpath you could do the following:
fiddle
using System;
using HtmlAgilityPack;
public class Program
{
public static void Main()
{
string url = "https://best.aliexpress.com/api/load_ams_path.do?path=aliexpress.com/common/#langField/ru/c-women-content.htm";
HtmlWeb web = new HtmlWeb();
var htmlDoc = web.Load(url);
var nodetest1 = htmlDoc.DocumentNode.SelectSingleNode("*//li[#class='sup-brand-item'][1]/a");
Console.WriteLine(nodetest1.Attributes["href"].Value);
}
}
I have different plugins in my Web api project with their own XML docs, and have one centralized Help page, but the problem is that Web Api's default Help Page only supports single documentation file
new XmlDocumentationProvider(HttpContext.Current.Server.MapPath("~/App_Data/Documentation.xml"))
How is it possible to load config from different files? I wan to do sth like this:
new XmlDocumentationProvider("PluginsFolder/*.xml")
You can modify the installed XmlDocumentationProvider at Areas\HelpPage to do something like following:
Merge multiple Xml document files into a single one:
Example code(is missing some error checks and validation):
using System.Xml.Linq;
using System.Xml.XPath;
XDocument finalDoc = null;
foreach (string file in Directory.GetFiles(#"PluginsFolder", "*.xml"))
{
if(finalDoc == null)
{
finalDoc = XDocument.Load(File.OpenRead(file));
}
else
{
XDocument xdocAdditional = XDocument.Load(File.OpenRead(file));
finalDoc.Root.XPathSelectElement("/doc/members")
.Add(xdocAdditional.Root.XPathSelectElement("/doc/members").Elements());
}
}
// Supply the navigator that rest of the XmlDocumentationProvider code looks for
_documentNavigator = finalDoc.CreateNavigator();
Kirans solution works very well. I ended up using his approach but by creating a copy of XmlDocumentationProvider, called MultiXmlDocumentationProvider, with an altered constructor:
public MultiXmlDocumentationProvider(string xmlDocFilesPath)
{
XDocument finalDoc = null;
foreach (string file in Directory.GetFiles(xmlDocFilesPath, "*.xml"))
{
using (var fileStream = File.OpenRead(file))
{
if (finalDoc == null)
{
finalDoc = XDocument.Load(fileStream);
}
else
{
XDocument xdocAdditional = XDocument.Load(fileStream);
finalDoc.Root.XPathSelectElement("/doc/members")
.Add(xdocAdditional.Root.XPathSelectElement("/doc/members").Elements());
}
}
}
// Supply the navigator that rest of the XmlDocumentationProvider code looks for
_documentNavigator = finalDoc.CreateNavigator();
}
I register the new provider from HelpPageConfig.cs:
config.SetDocumentationProvider(new MultiXmlDocumentationProvider(HttpContext.Current.Server.MapPath("~/App_Data/")));
Creating a new class and leaving the original one unchanged may be more convenient when upgrading etc...
Rather than create a separate class along the lines of XmlMultiDocumentationProvider, I just added a constructor to the existing XmlDocumentationProvider. Instead of taking a folder name, this takes a list of strings so you can still specify exactly which files you want to include (if there are other xml files in the directory that the Documentation XML are in, it might get hairy). Here's my new constructor:
public XmlDocumentationProvider(IEnumerable<string> documentPaths)
{
if (documentPaths.IsNullOrEmpty())
{
throw new ArgumentNullException(nameof(documentPaths));
}
XDocument fullDocument = null;
foreach (var documentPath in documentPaths)
{
if (documentPath == null)
{
throw new ArgumentNullException(nameof(documentPath));
}
if (fullDocument == null)
{
using (var stream = File.OpenRead(documentPath))
{
fullDocument = XDocument.Load(stream);
}
}
else
{
using (var stream = File.OpenRead(documentPath))
{
var additionalDocument = XDocument.Load(stream);
fullDocument?.Root?.XPathSelectElement("/doc/members").Add(additionalDocument?.Root?.XPathSelectElement("/doc/members").Elements());
}
}
}
_documentNavigator = fullDocument?.CreateNavigator();
}
The HelpPageConfig.cs looks like this. (Yes, it can be fewer lines, but I don't have a line limit so I like splitting it up.)
var xmlPaths = new[]
{
HttpContext.Current.Server.MapPath("~/bin/Path.To.FirstNamespace.XML"),
HttpContext.Current.Server.MapPath("~/bin/Path.To.OtherNamespace.XML")
};
var documentationProvider = new XmlDocumentationProvider(xmlPaths);
config.SetDocumentationProvider(documentationProvider);
I agree with gurra777 that creating a new class is a safer upgrade path. I started with that solution but it involves a fair amount of copy/pasta, which could easily get out of date after a few package updates.
Instead, I am keeping a collection of XmlDocumentationProvider children. For each of the implementation methods, I'm calling into the children to grab the first non-empty result.
public class MultiXmlDocumentationProvider : IDocumentationProvider, IModelDocumentationProvider
{
private IList<XmlDocumentationProvider> _documentationProviders;
public MultiXmlDocumentationProvider(string xmlDocFilesPath)
{
_documentationProviders = new List<XmlDocumentationProvider>();
foreach (string file in Directory.GetFiles(xmlDocFilesPath, "*.xml"))
{
_documentationProviders.Add(new XmlDocumentationProvider(file));
}
}
public string GetDocumentation(System.Reflection.MemberInfo member)
{
return _documentationProviders
.Select(x => x.GetDocumentation(member))
.FirstOrDefault(x => !string.IsNullOrWhiteSpace(x));
}
//and so on...
The HelpPageConfig registration is the same as in gurra777's answer,
config.SetDocumentationProvider(new MultiXmlDocumentationProvider(HttpContext.Current.Server.MapPath("~/App_Data/")));
Below code specifies that we we can make http connection in blackberry and how to store html page as a string?
I am doing this but I am able to get that http request but when I get response i.e http_ok it is not correct so that I can save text oh html as a string and I can further store that into sqlite.
LabelField title = new LabelField("SQLite Create Database Sample",
LabelField.ELLIPSIS |
LabelField.USE_ALL_WIDTH);
setTitle(title);
add(new RichTextField("Creating a database."));
argURL="https://www.google.com:80";
try {
connDesc = connFact.getConnection(argURL);
if (connDesc != null) {
httpConn = (HttpConnection) connDesc.getConnection();
// //Send Data on this connection
// httpConn.setRequestMethod(HttpConnection.GET);
// //Server Response
StringBuffer strBuffer = new StringBuffer();
inStream = httpConn.openInputStream();
int chr;
int retResponseCode = httpConn.getResponseCode();
if (retResponseCode == HttpConnection.HTTP_OK) {
if (inStream != null) {
while ((chr = inStream.read()) != -1) {
strBuffer.append((char) chr);
}
serverResponceStr = strBuffer.toString();
// appLe.alertForms.get_userWaitAlertForm().append("\n"+serverResponceStr);
//returnCode = gprsConstants.retCodeSuccess;
}
} else {
//returnCode = gprsConstants.retCodeNOK;
}
}
} catch (Exception excp) {
//returnCode = gprsConstants.retCodeDisconn;
excp.printStackTrace();
} `enter code here`
The code does not perform any database functionality, however I tested and it does successfully perform an HttpRequest to an external URL. The data that comes back is based on the response of the server you are making the request to.
The code I used can be found here:
http://snipt.org/vrl7
The only modifications is to keep a running summary of various events, and the response is displayed in the RichTextField. Basically, this looks to be working as intended, and the resulting String should be able to be saved however you see fit; though you may need to be cautious of encoding when saving to a database so that special characters are not lost or misinterpreted.
I've had several cases where I had a page with several query parameters - most recently a search results page - and needed to create a link to the same page with one or more query parameters changed in the URL. This seems like such a common use case that I feel as though there must be some simple built-in way of doing it.
Right now, I'm using a function I wrote which takes in a dictionary of parameters and values and merges them with the params and values from Request.QueryString. Parameters given with a null value are removed. It works, but I'm open to simpler methods.
Minor improvements I'd suggest:
//...
{
UriBuilder ub = new UriBuilder(Request.Url);
//...
ub.Query = string.Join("&", parameters.Select(kv => string.Format("{0}={1}", Server.UrlEncode(kv.Key), Server.UrlEncode(kv.Value))));
return ub.ToString();
}
Edit
Actually the return value should also be a Uri type but I didn't want to introduce any breaking changes.
The function I'm using now:
public string ThisPageWithParams(IDictionary<string, string> newParameters)
{
string url = Request.Url.AbsolutePath + "?";
var parameters = new Dictionary<string, string>();
foreach (string k in Request.QueryString)
{
parameters[k] = Request.QueryString[k];
}
foreach (var kv in newParameters)
{
if (newParameters[kv.Key] == null)
{
parameters.Remove(kv.Key);
}
else
{
parameters[kv.Key] = kv.Value;
}
}
url += string.Join("&", parameters.Select(kv => Server.UrlEncode(kv.Key) + "=" + Server.UrlEncode(kv.Value)));
return url;
}
I'm trying to port an existing AJAX app to Flex, and having trouble with the encoding of parameters sent to the backend service.
When trying to perform the action of deleting a contact, the existing app performs a POST, sending the the following: (captured with firebug)
contactRequest.contacts[0].contactId=2c33ddc6012a100096326b40a501ec72
So, I create the following code:
var service:HTTPService;
function initalizeService():void
{
service = new HTTPService();
service.url = "http://someservice";
service.method = 'POST';
}
public function sendReq():void
{
var params:Object = new Object();
params['contactRequest.contacts[0].contactId'] = '2c33ddc6012a100097876b40a501ec72';
service.send(params);
}
In firebug, I see this sent out as follows:
Content-type: application/x-www-form-urlencoded
Content-length: 77
contactRequest%2Econtacts%5B0%5D%2EcontactId=2c33ddc6012a100097876b40a501ec72
Flex is URL encoding the params before sending them, and we're getting an error returned from the server.
How do I disable this encoding, and get the params sent as-is, without the URL encoding?
I feel like the contentType property should be the key - but neither of the defined values work.
Also, I've considered writing a SerializationFilter, but this seems like overkill - is there a simpler way?
Writing a SerializtionFilter seemed to do the trick:
public class MyFilter extends SerializationFilter
{
public function MyFilter()
{
super();
}
override public function serializeBody(operation:AbstractOperation, obj:Object):Object
{
var s:String = "";
var classinfo:Object = ObjectUtil.getClassInfo(obj);
for each (var p:* in classinfo.properties)
{
var val:* = obj[p];
if (val != null)
{
if (s.length > 0)
s += "&";
s += StringUtil.substitute("{0}={1}",p,val);
}
}
return s;
}
}
I'd love to know any alternative solutions that don't involve doing this though!
