问题描述
我最近从TweetSharp切换到LinqToTwitter和一件事,我缺少的是检索鸣叫为HTML的方式。
TweetSharp呼吁的方法 .TextAsHtml()
自动链接提到,哈希标签和超链接。
有谁知道,如果这样的功能在LinqtoTwitter存在吗? 。任何洞察TweetSharp是如何能够做到这一点会非常appricated
更新:
看起来好像TweetSharp使用正则表达式匹配的URL,提到和哈希标签。这里有一个例子:
私有静态只读正则表达式_parseUrls =新的正则表达式(\\b(([\\\ ??\\w-] +:// |万维网[])[^ \\s()&所述;>] +(:\\([\\w\\d] + \\)|([^ \\p {P} \\s] | /))),RegexOptions.IgnoreCase | RegexOptions.Compiled);
私人静态只读正则表达式_parseMentions =新的正则表达式((^ | \\W)@([A-ZA-Z0-9 _] +),RegexOptions.IgnoreCase | RegexOptions.Compiled);
私人静态只读正则表达式_parseHashtags =新的正则表达式([#] + [A-ZA-Z0-9 -_] +,RegexOptions.IgnoreCase | RegexOptions.Compiled);
下面是我使用了一些逻辑从TweetSharp的最终解决方案图书馆。它很好地工作了:
///<总结>
///扩展了LinqToTwitter库
///< /总结>
公共静态类TwitterExtensions
{
私人静态只读正则表达式_parseUrls =新的正则表达式(\\b(([\\w-] +:// | WWW [ ])[^ \\s()&所述;]的计算值+(?: \\([\\w\\d] + \\)|([^ \ \p {P} \\s] | /))),RegexOptions.IgnoreCase | RegexOptions.Compiled);
私人静态只读正则表达式_parseMentions =新的正则表达式((^ | \\W)@([A-ZA-Z0-9 _] +),RegexOptions.IgnoreCase | RegexOptions.Compiled);
私人静态只读正则表达式_parseHashtags =新的正则表达式([#] + [A-ZA-Z0-9 -_] +,RegexOptions.IgnoreCase | RegexOptions.Compiled);

{
串tweetText = status.Text;
如果(!String.IsNullOrEmpty(tweetText))
{
//更换网址,
的foreach(VAR urlMatch在_parseUrls.Matches(tweetText))
{
匹配匹配=(匹配)urlMatch;
tweetText = tweetText.Replace(match.Value,的String.Format(< A HREF = \{0} \目标= \_blank\> {0}< /一个>中,match.Value));
}
//替换提及
的foreach(VAR mentionMatch在_parseMentions.Matches(tweetText))
{
匹配匹配=(匹配)mentionMatch;
如果(match.Groups.Count == 3)
{
字符串值= match.Groups [2] .value的;
字符串文本=@+价值;
tweetText = tweetText.Replace(文字,的String.Format(< A HREF = \http://twitter.com/{0}\TARGET = \_blank\> {1}&下; / A>中,值,文本));
}
}
//替换哈希标签
的foreach(VAR hashMatch在_parseHashtags.Matches(tweetText))
{
匹配匹配=(匹配)hashMatch;
查询字符串= Uri.EscapeDataString(match.Value);
tweetText = tweetText.Replace(match.Value,的String.Format(< A HREF = \http://search.twitter.com/search?q={0}\TARGET = \\ \\_blank\> {1}&下; / A>中,查询match.Value));
}
}
返回tweetText;
}
}
I recently switched from TweetSharp to LinqToTwitter and the one thing I'm missing is a way to retrieve a tweet as HTML.
TweetSharp had a method called .TextAsHtml()
which automatically linked mentions, hash tags, and hyperlinks.
Does anyone know if such a feature exist in LinqtoTwitter? Any insight into how TweetSharp was able to accomplish this would be much appricated.
UPDATE:
It looks as though TweetSharp used Regular Expressions to match URLs, mentions, and hash tags. Here is a sample:
private static readonly Regex _parseUrls = new Regex("\\b(([\\w-]+://?|www[.])[^\\s()<>]+(?:\\([\\w\\d]+\\)|([^\\p{P}\\s]|/)))", RegexOptions.IgnoreCase | RegexOptions.Compiled);
private static readonly Regex _parseMentions = new Regex("(^|\\W)@([A-Za-z0-9_]+)", RegexOptions.IgnoreCase | RegexOptions.Compiled);
private static readonly Regex _parseHashtags = new Regex("[#]+[A-Za-z0-9-_]+", RegexOptions.IgnoreCase | RegexOptions.Compiled);
Here is my final solution which uses some logic from TweetSharp's library. It's working out nicely:
/// <summary>
/// Extends the LinqToTwitter Library
/// </summary>
public static class TwitterExtensions
{
private static readonly Regex _parseUrls = new Regex("\\b(([\\w-]+://?|www[.])[^\\s()<>]+(?:\\([\\w\\d]+\\)|([^\\p{P}\\s]|/)))", RegexOptions.IgnoreCase | RegexOptions.Compiled);
private static readonly Regex _parseMentions = new Regex("(^|\\W)@([A-Za-z0-9_]+)", RegexOptions.IgnoreCase | RegexOptions.Compiled);
private static readonly Regex _parseHashtags = new Regex("[#]+[A-Za-z0-9-_]+", RegexOptions.IgnoreCase | RegexOptions.Compiled);
/// <summary>
/// Parse Status Text to HTML equivalent
/// </summary>
/// <param name="status">The LinqToTwitter <see cref="Status"/></param>
/// <returns>Formatted HTML string</returns>
public static string TextAsHtml(this Status status)
{
string tweetText = status.Text;
if (!String.IsNullOrEmpty(tweetText))
{
// Replace URLs
foreach (var urlMatch in _parseUrls.Matches(tweetText))
{
Match match = (Match)urlMatch;
tweetText = tweetText.Replace(match.Value, String.Format("<a href=\"{0}\" target=\"_blank\">{0}</a>", match.Value));
}
// Replace Mentions
foreach (var mentionMatch in _parseMentions.Matches(tweetText))
{
Match match = (Match)mentionMatch;
if (match.Groups.Count == 3)
{
string value = match.Groups[2].Value;
string text = "@" + value;
tweetText = tweetText.Replace(text, String.Format("<a href=\"http://twitter.com/{0}\" target=\"_blank\">{1}</a>", value, text));
}
}
// Replace Hash Tags
foreach (var hashMatch in _parseHashtags.Matches(tweetText))
{
Match match = (Match)hashMatch;
string query = Uri.EscapeDataString(match.Value);
tweetText = tweetText.Replace(match.Value, String.Format("<a href=\"http://search.twitter.com/search?q={0}\" target=\"_blank\">{1}</a>", query, match.Value));
}
}
return tweetText;
}
}
