<p>ここまでたどり着いた人は、最初の<a href="../c1/1.html">クイックスタート</a>を開いてみてください。</p>
<p>そこには<code>profile</code>と<code>notify</code>についてこのように記述されています。</p>
<pre><code class="lang-sh"><span class="hljs-comment"># profile</span>
curl <span class="hljs-_">-s</span>L -X GET -H <span class="hljs-string">"Content-Type: application/json"</span> \
-H <span class="hljs-string">"Authorization: Bearer <span class="hljs-variable">$token</span>"</span> \
<span class="hljs-string">"https://bsky.social/xrpc/app.bsky.actor.getProfile?actor=<span class="hljs-variable">${handle}</span>"</span>
<span class="hljs-comment"># notify</span>
curl <span class="hljs-_">-s</span>L -X GET -H <span class="hljs-string">"Content-Type: application/json"</span> \
-H <span class="hljs-string">"Authorization: Bearer <span class="hljs-variable">$token</span>"</span> \
https://bsky.social/xrpc/app.bsky.notification.listNotifications
</code></pre>
<p>非常に似ていますね。</p>
<p>まずは、先程作ったアプリの<code>profile</code>コマンドの使い方を紹介します。</p>
<pre><code class="lang-sh">$ ./target/debug/ai p yui.syui.ai
</code></pre>
<p>調べたい<code>handle</code>を引数にすることで、プロフィールを取得するコマンドです。</p>
<p>では、<code>profile</code>コマンドのコードの中身を見てみましょう。</p>
<div><p class="code-filename">src/profile.rs</p></div>
<pre><code class="lang-rust"><span class="hljs-keyword">extern</span> <span class="hljs-keyword">crate</span> reqwest;
<span class="hljs-keyword">use</span> crate::token_toml;
<span class="hljs-keyword">pub</span> async <span class="hljs-function"><span class="hljs-keyword">fn</span> <span class="hljs-title">get_request</span></span>(handle: <span class="hljs-built_in">String</span>) -> <span class="hljs-built_in">String</span> {
<span class="hljs-keyword">let</span> token = token_toml(&<span class="hljs-string">"access"</span>);
<span class="hljs-keyword">let</span> url = <span class="hljs-string">"https://bsky.social/xrpc/app.bsky.actor.getProfile"</span>.to_owned() + &<span class="hljs-string">"?actor="</span> + &handle;
<span class="hljs-keyword">let</span> client = reqwest::Client::new();
<span class="hljs-keyword">let</span> res = client
.get(url)
.header(<span class="hljs-string">"Authorization"</span>, <span class="hljs-string">"Bearer "</span>.to_owned() + &token)
.send()
.await
.unwrap()
.text()
.await
.unwrap();
<span class="hljs-keyword">return</span> res
}
</code></pre>
<p>例えば、これを<code>notify</code>を取得するurlに変更すると、<code>notify</code>コマンドに変化します。以下のように書き換えてみてください。</p>
<div><p class="code-filename">src/profile.rs</p></div>
<pre><code class="lang-rust"><span class="hljs-keyword">extern</span> <span class="hljs-keyword">crate</span> reqwest;
<span class="hljs-keyword">use</span> crate::token_toml;
<span class="hljs-keyword">pub</span> async <span class="hljs-function"><span class="hljs-keyword">fn</span> <span class="hljs-title">get_request</span></span>(handle: <span class="hljs-built_in">String</span>) -> <span class="hljs-built_in">String</span> {
<span class="hljs-keyword">let</span> token = token_toml(&<span class="hljs-string">"access"</span>);
<span class="hljs-comment">//let url = "https://bsky.social/xrpc/app.bsky.actor.getProfile".to_owned() + &"?actor=" + &handle;</span>
<span class="hljs-keyword">let</span> url = <span class="hljs-string">"https://bsky.social/xrpc/app.bsky.notification.listNotifications"</span>;
<span class="hljs-keyword">let</span> client = reqwest::Client::new();
<span class="hljs-keyword">let</span> res = client
.get(url)
.header(<span class="hljs-string">"Authorization"</span>, <span class="hljs-string">"Bearer "</span>.to_owned() + &token)
.send()
.await
.unwrap()
.text()
.await
.unwrap();
<span class="hljs-keyword">return</span> res
}
</code></pre>
<p>これを<code>build</code>して実行してみましょう。</p>
<pre><code class="lang-sh">$ cargo build
$ ./target/debug/ai p yui.syui.ai
</code></pre>
<p>コマンド結果が通知の取得に変化しています。</p>
<p>ただし、引数である<code>yui.syui.ai</code>は全く関係ありません。引数がなんでも通ります。</p>
<p>ですが、この<code>src/profile.rs</code>を引用する<code>src/main.rs</code>側のコードが引数を必要とするため、これを省略すると動かなくなってしまうのです。</p>
<div><p class="code-filename">src/main.rs</p></div>
<pre><code class="lang-rust"><span class="hljs-function"><span class="hljs-keyword">fn</span> <span class="hljs-title">profile</span></span>(c: &Context) {
<span class="hljs-comment">// ここで引数を取得している</span>
<span class="hljs-keyword">let</span> m = c.args[<span class="hljs-number">0</span>].to_string();
<span class="hljs-keyword">let</span> h = async {
<span class="hljs-comment">// 先程のコードはhandleを欲しがるため、ここで引数を取得した"m"を入れている</span>
<span class="hljs-keyword">let</span> <span class="hljs-keyword">str</span> = profile::get_request(m.to_string()).await;
<span class="hljs-built_in">println!</span>(<span class="hljs-string">"{}"</span>,<span class="hljs-keyword">str</span>);
};
<span class="hljs-keyword">let</span> res = tokio::runtime::Runtime::new().unwrap().block_on(h);
<span class="hljs-keyword">return</span> res
}
</code></pre>
<p>逆に言うと、<code>src/profile.rs</code>をコピーして一部を削除することで、新たに通知コマンドを作れるということです。</p>
<p>新しく<code>notify</code>コマンドを作成してみましょう。</p>
<pre><code class="lang-sh">$ cp src/profile.rs src/notify.rs
</code></pre>
<div><p class="code-filename">src/notify.rs</p></div>
<pre><code class="lang-rust"><span class="hljs-keyword">extern</span> <span class="hljs-keyword">crate</span> reqwest;

<span class="hljs-keyword">let</span> url = <span class="hljs-string">"https://bsky.social/xrpc/app.bsky.notification.listNotifications"</span>;
<span class="hljs-keyword">let</span> client = reqwest::Client::new();

.unwrap()

.unwrap();
<span class="hljs-keyword">return</span> res
}

<p><code>timeline</code>の取得も似たような感じです。是非、チャレンジしてみてください。</p>
