<h3 id="websocket-proxy-server"><a class="header" href="#websocket-proxy-server">WebSocket Proxy Server</a></h3>
|
|
<p>Because web browsers don't have the ability to make TCP connections directly, TLSNotary requires a WebSocket proxy to set up TCP connections when it is used in a browser. To facilitate the exploration of TLSNotary and to run the examples easily, the TLSNotary team hosts a public WebSocket proxy server. This server can be used to access the following whitelisted domains:</p>
|
|
<pre><code>api.twitter.com:443
|
|
twitter.com:443
|
|
gateway.reddit.com:443
|
|
reddit.com:443
|
|
swapi.dev:443
|
|
api.x.com:443
|
|
x.com:443
|
|
discord.com:443
|
|
connect.garmin.com:443
|
|
uber.com:443
|
|
riders.uber.com:443
|
|
m.uber.com:443
|
|
</code></pre>
|
|
<p>You can utilize this WebSocket proxy with the following syntax:</p>
|
|
<pre><code>wss://notary.pse.dev/proxy?token=<domain>
|
|
</code></pre>
|
|
<p>Replace <code><domain></code> with the domain you wish to access (for example, <code>swapi.dev</code>).</p>
