Twitter API from C#: Searching
Following my post Twitter API From C#: Getting a User’s Time Line, I’ll talk about how to use the Twitter Search API.
The main difference between this post and the previous one, is that Twitter Search API currently does not support XML response, and supports only atom and json. So, in order to search for specific terms, I’ll have to take another approach than the one I took before.
Performing a Search
To perform a search in the browser for “DevAcademy3”, I can navigate to: http://search.twitter.com/search?q=devacademy3&show-user=true
In order to get the response in a json format, I’ll use: http://search.twitter.com/search.json?q=devacademy3&show-user=true (added “.json” after the work “search”).
Here’s a sample of the result that contains a list of results with 2 items in it:
{"results":
[
{"text":"Working on my Silverlight demo for #devacademy3",
"to_user_id":null,
"from_user":"bursteg",
"id":997265406,
"from_user_id":145367,
"iso_language_code":"en",
"profile_image_url":"http:\/\/s3.amazonaws.com\/twitter_production\/profile_images\/30327862\/Guy_Burstein_Small_normal.jpg",
"created_at":"Sun, 09 Nov 2008 08:06:24 +0000"},
{"text":"Registration for #devacademy3 should be open this week",
"to_user_id":null,
"from_user":"devacademy3",
"id":996482591,
"from_user_id":2271567,
"iso_language_code":"en",
"profile_image_url":
"http:\/\/s3.amazonaws.com\/twitter_production\/profile_images\/63650042\/DevAcademy3Logo_-_Copy_normal.jpg",
"created_at":"Sat, 08 Nov 2008 16:42:48 +0000"}
],
"since_id":0,
"max_id":998769058,
"refresh_url":"?since_id=998769058&q=devacademy3",
"results_per_page":15,
"page":1,
"query":
"devacademy3"
}
Using the DataContract and DataMember Attributes
In order to extract the data of of this result, I created a SearchResult Class, that will represent a single item in the result, decorated with the appropriate DataContract attributes, that indicate from which attribute in the result should the value be taken.
[DataContract]
public class SearchResult
{
[DataMember(Name = "text", Order = 0)]
public string Text { get; set; }
[DataMember(Name = "to_user_id", Order = 1)]
public int? ToUserId { get; set; }
[DataMember(Name = "from_user", Order = 2)]
public string FromUser { get; set; }
[DataMember(Name = "id", Order = 3)]
public int Id { get; set; }
[DataMember(Name = "from_user_id", Order = 4)]
public int? FromUserId { get; set; }
[DataMember(Name = "iso_language_code", Order = 5)]
public string IsoLanguageCode { get; set; }
[DataMember(Name = "profile_image_url", Order = 6)]
public string ProfileImageUrl { get; set; }
[DataMember(Name = "created_at", Order = 7)]
public string CreatedAt { get; set; }
}
In addition to that, since the items are encapsulated within a list inside an object, I also created the following SearchResults class:
[DataContract]
public class SearchResults
{
public SearchResults()
{
this.Results = new List<SearchResult>();
}
[DataMember(Name = "results")]
public List<SearchResult> Results { get; set; }
}
Using the DataContractJsonSerializer to Extract the Data
Using the WebHttpWegRequest (with the Get method I created in my previous post), I received the response as a string.
This is the code I used in order to deserialize the response into SearchReaults objects (using the DataContractJsonSerializer in System.Runtime.Serialization.Json namespace).
string response =
Get("http://search.twitter.com/search.json?q=devacademy3&show-user=true");
byte[] brr = ASCIIEncoding.UTF8.GetBytes(response);
StreamReader reader = new StreamReader(new MemoryStream(brr));
DataContractJsonSerializer serializer =
new DataContractJsonSerializer(typeof(SearchResults));
SearchResults searchResults =
(SearchResults)serializer.ReadObject(reader.BaseStream);
reader.Close();
Constructing a Meaningful List of Statuses
Now that I have the search results objects, I can construct a meaningful response using the UserStatus class I created in the previous post, and with some transformations and parsing, get the data I wanted to.
List<UserStatus> users =
(from u in searchResults.Results
select new UserStatus
{
UserName = u.FromUser,
ProfileImage = u.ProfileImageUrl,
Status = HttpUtility.HtmlDecode(u.Text),
StatusDate = DateTimeOffset.Parse(u.CreatedAt).UtcDateTime
}).ToList();
Notice I used HttpUtility (in System.Web namespace) in order to decode special characters such as > to their readable characters.
Wrapping it up...
The final version of the Search method looks like this:
public List<UserStatus> Search(string searchTerm)
{
string url =
string.Format("http://search.twitter.com/search.json?&q={0}", searchTerm);
string response = Get(url);
byte[] brr = ASCIIEncoding.UTF8.GetBytes(response);
StreamReader reader = new StreamReader(new MemoryStream(brr));
DataContractJsonSerializer serializer =
new DataContractJsonSerializer(typeof(SearchResults));
SearchResults searchResults =
(SearchResults)serializer.ReadObject(reader.BaseStream);
reader.Close();
List<UserStatus> users =
(from u in searchResults.Results
select new UserStatus
{
UserName = u.FromUser,
ProfileImage = u.ProfileImageUrl,
Status = HttpUtility.HtmlDecode(u.Text),
StatusDate = DateTimeOffset.Parse(u.CreatedAt).UtcDateTime
}).ToList();
return users;
}
Enjoy Twitter Searching with C#!
Twitter API From C#: Getting a User’s Time Line
From Twitter’s REST API:
User Timeline:
Returns the 20 most recent statuses posted from the authenticating user:
http://twitter.com/statuses/user_timeline.xml
It's also possible to request another user's timeline. For example:
http://twitter.com/statuses/user_timeline/bursteg.xml
Making an HTTP Request
Since all the API is expressed in REST, I figured out that I need a simple reusable method to perform HTTP requests. This method takes the URL and the method (GET or POST), gets the credentials from the configuration file and makes the request.
private string PerformRequest(string method, string url)
{
string user = ConfigurationManager.AppSettings["user"];
string password = ConfigurationManager.AppSettings["password"];
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
request.Method = method;
request.Credentials = new NetworkCredential(user, password);
WebResponse response = request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
string responseString = reader.ReadToEnd();
reader.Close();
return responseString;
}
Just for the simplicity, I also added the following methods:
private string Post(string url)
{
return PerformRequest("POST", url);
}
private string Get(string url)
{
return PerformRequest("GET", url);
}
Getting a User’s Time Line from Twitter
Using the following code, you can get a user’s timeline from twitter in xml format:
string url = string.Format("http://twitter.com/statuses/friends/{0}.xml", user);
string response = Get(url);
This call returns the following piece of xml:
<?xml version="1.0" encoding="UTF-8"?>
<statuses type="array">
<status>
<created_at>Sat Nov 15 10:08:15 +0000 2008</created_at>
<id>1006846483</id>
<text>Testing "posts" #devacademy3</text>
<source>web</source>
<truncated>false</truncated>
<in_reply_to_status_id></in_reply_to_status_id>
<in_reply_to_user_id></in_reply_to_user_id>
<favorited>false</favorited>
<user>
<id>6849932</id>
<name>Guy Burstein</name>
<screen_name>bursteg</screen_name>
<location></location>
<description></description>
<profile_image_url>http://.../Guy_Burstein_Small_normal.jpg</profile_image_url>
<url>http://blogs.microsoft.co.il/blogs/bursteg</url>
<protected>false</protected>
<followers_count>42</followers_count>
</user>
</status>
<status>
...
</status>
</statuses>
As we can see, this response is an array of statuses, each contains the details about the user who posted it.
Extracting the Data
With my favor to LINQ to XML, I used it to extract the data that I was interested in, and construct CLR objects that I can easily work with.
XDocument document = XDocument.Parse(response, LoadOptions.None);
var query = from e in document.Root.Descendants("status")
select new UserStatus
{
UserName = e.Element("user").Element("name").Value,
ProfileImage = e.Element("user").Element("profile_image_url").Value,
Status = HttpUtility.HtmlDecode(e.Element("text").Value),
StatusDate = (e.Element("created_at").Value.ParseDateTime())
};
First, I parsed an xml document from the response string. Then, I created a list of UserStatus objects from the contents of the response xml.
Few things to note about the above code:
1. HttpUtility.HtmlDecode is being used in order to get a readable text. The response contained text like “Testing "posts" #devacademy3” and this method (in System.Web) converts it to “Testing “posts” #devacademy3”.
2. The ParseDateTime() method on the element’s value is an extension method I created in order to parse a DateTime from the special string representation of the time the status was posted:
Sat Nov 15 10:08:15 +0000 2008
This method looks like:
public static class StringExtensions
{
public static DateTime ParseDateTime(this string date)
{
string dayOfWeek = date.Substring(0, 3).Trim();
string month = date.Substring(4, 3).Trim();
string dayInMonth = date.Substring(8, 2).Trim();
string time = date.Substring(11, 9).Trim();
string offset = date.Substring(20, 5).Trim();
string year = date.Substring(25, 5).Trim();
string dateTime = string.Format("{0}-{1}-{2} {3}", dayInMonth, month, year, time);
DateTime ret = DateTime.Parse(dateTime);
return ret;
}
}
If you come up with another idea of how to parse this string into a DateTime object, please let me know.
Wrapping it up...
The final version of the GetUserTimeLine method looks like this:
public List<UserStatus> GetUserTimeLine(string user)
{
string url = string.Format("http://twitter.com/statuses/user_timeline/{0}.xml", user);
string response = Get(url);
XDocument document = XDocument.Parse(response, LoadOptions.None);
var query = from e in document.Root.Descendants("status")
select new UserStatus
{
UserName = e.Element("user").Element("name").Value,
ProfileImage = e.Element("user").Element("profile_image_url").Value,
Status = HttpUtility.HtmlDecode(e.Element("text").Value),
StatusDate = (e.Element("created_at").Value.ParseDateTime())
};
List<UserStatus> users = (from u in query
where u.Status != ""
orderby u.StatusDate descending
select u).ToList();
return users;
}
The techniques I’ve used here can be used in almost all the “get” methods of the REST API of Twitter.
Enjoy!
