Getting Vine PostID from Video URL

Question

I'm using Vine API wrapper "VineSharp" nuget package to try and get some details about a Vine video. I have the video URL. i.e. : "https://vine.co/v/eYgeYlYAOQv" However, to get the vine post data, apparently VineSharp (as well as other Vine API wrappers) requests to insert the vine post ID - which I don't have.

I've searched google a lot to find out how can I get the post ID if I have the video URL or the video ID - but couldn't find anything.

If Vine API supports posts queries to get details of specific posts using the post's id, it won't be logical that the post ID itself can be retrieved only from Json of another API call like a timeline or channel request...

What am I missing?

Answer 1

A kind of hacky way to do this is downloading the contents of https://vine.co/v/eYgeYlYAOQv with the WebClient class and parsing the result with a regular expression.

The post ID appears multiple times in the returned web page. You could use one of the following regular expressions (or both to be sure):

vine://post/(\d+)[^\d]

"postIdStr":\s*"(\d+)"

The first match group will contain the post ID.

Here is a working example that tries both patterns: https://regex101.com/r/aV9fD8/4

Here is a working example that downloads the website, tries both patterns and prints the first matching post ID: https://dotnetfiddle.net/klWnxw

using (var client = new WebClient())
{       
    var content = client.DownloadString("https://vine.co/v/eYgeYlYAOQv");

    var postIdMatch = Regex.Match(
        content, 
        @"vine://post/(\d+)[^\d]|""postIdStr"":\s*""(\d+)""");

    if (postIdMatch.Success)
        Console.WriteLine(
            postIdMatch.Groups[1].Value != string.Empty 
                ? postIdMatch.Groups[1].Value 
                : postIdMatch.Groups[2].Value);
    else
        Console.WriteLine("No post ID found.");
}
