Get steamID by user nickname

Question

Is it possible to get user's steamID by his nickname? I didn't find solution in steam API documentation. The only one thing that I found is an old post on http://dev.dota2.com :

You can use this to search the Dota2 API directly using the player_name option of GetMatchHistory You can then find their 32-bit ID in the list and then convert it to a 64-bit ID.

But now GetMatchHistory function does not have player_name parameter. Now it requires account_id.

So how the websites like http://dotabuff.com/search?q=Dendi get this info?

Solution 1

You can use

GET http://api.steampowered.com/ISteamUser/ResolveVanityURL/v0001/

to get the SteamID from the custom URL of a Steam Profile. See http://wiki.teamfortress.com/wiki/WebAPI/ResolveVanityURL

You can't get the steamID from someone's current nickname because nicknames can change and are not unique.

Solution 2

Using PHP and the Steam Condenser project, you can accomplish this.

require_once('steam/steam-condenser.php');

$playername = 'NAMEOFPLAYER';
try
{
    $id = SteamId::create($playername);
} 
catch (SteamCondenserException $s)
{
    // Error occurred
}

echo $id->getSteamId;

There are usage examples in the wiki for the project if you need more information.

Solution 3

This is JS answer, not PHP, but anyway

You can use this url address to get list of users from steamcommunity.com/search/ page

https://steamcommunity.com/search/SearchCommunityAjax?text=aaa&filter=users&sessionid=session&steamid_user=false&page=1

text means username, sessionid means sessionid from cookie files, which you can obtain by going to the site itself

Here is my crappy code for demo:

let axios = require('axios').default;

//create axios instance from which we will get to the search list
let instance = axios.create({ baseURL: 'https://steamcommunity.com' });

async function getSessionId() {

  let res = await axios.get('https://steamcommunity.com/');
  
  let [cookie] = res.headers['set-cookie'];
  
  instance.defaults.headers.Cookie = cookie;
  
  return cookie;

}

getSessionId().then(cookie => {

  let session = cookie.split(' ')[0].slice(10, -1);
  instance.get(`https://steamcommunity.com/search/SearchCommunityAjax?text=aaa&filter=users&sessionid=${session}&steamid_user=false&page=1`).then(res => {
  
    //i have regex
    let regex = /('<div>')/|/('<img>')/|/('<span>')/g
    
    //html also
    let arr = res.data.html.split(regex).join('').split('\t').join('').split('\n').join('').split('\r');

    arr = arr.filter(a => a !== '');
    
    arr = arr.filter(a => a.includes("searchPersonaName"));
    
    let result = [];

    arr.forEach(a => {
            
            let [link, name] = a.replace('<a class="searchPersonaName" href="','').replace('</a><br />','').split('">');

            let obj = {

                link,

                name

            };

            result.push(obj);
        
        });

        console.log(result); //logs out array of objects with links and usernames
  
  })
  
})

Yes. This function requires steamids param. Which is set of steam IDs. Not nicknames.

I guess this is not possible anymore :D

Small addendum: just like nicknames, custom URLs can change too. But since custom URLs are unique, you'll have to handle cases like "what if two players swapped their URLs?".
