# 搜索 您可以通过提供搜索 **查询** 到 `youtube_search` 或 `youtube_search_max` 源来搜索 YouTube 上的视频、频道、播放列表或电影。 {% hint style="info" %} 该`youtube_search` 源允许检索最多 **20** 个搜索结果，而 `youtube_search_max` 源可在单次响应中返回最多 **700** 个结果。 {% endhint %} 此来源也可以与 `youtube_autocomplete` 源相结合，以包含建议并定位相关关键字和搜索词。 下面的示例演示如何使用 `youtube_search` 源基于搜索 **查询检索 YouTube 视频。** {% tabs %} {% tab title="cURL" %} ```bash curl 'https://realtime.oxylabs.io/v1/queries' \ --user 'USERNAME:PASSWORD' \ -H 'Content-Type: application/json' \ -d '{ "source": "youtube_search", "query": "how to make a website" }' ``` {% endtab %} {% tab title="Python" %} ```python import requests from pprint import pprint # 构建负载。 payload = { 'source': 'youtube_search', 'query': 'how to make a website' } # 获取响应。 response = requests.request( 'POST', 'https://realtime.oxylabs.io/v1/queries', auth=('user', 'pass1'), json=payload, ) # 打印带有结果的 JSON 响应。 pprint(response.json()) ``` {% endtab %} {% tab title="Node.js" %} ```javascript const https = require("https"); const username = "USERNAME"; const password = "PASSWORD"; const body = { source: "youtube_search", query: "how to make a website" }; const options = { hostname: "realtime.oxylabs.io", path: "/v1/queries", method: "POST", headers: { "Content-Type": "application/json", Authorization: "Basic " + Buffer.from(`${username}:${password}`).toString("base64"), }, }; const request = https.request(options, (response) => { let data = ""; response.on("data", (chunk) => { data += chunk; }); response.on("end", () => { const responseData = JSON.parse(data); console.log(JSON.stringify(responseData, null, 2)); }); }); request.on("error", (error) => { console.error("Error:", error); }); request.write(JSON.stringify(body)); request.end(); ``` {% endtab %} {% tab title="HTTP" %} ```http https://realtime.oxylabs.io/v1/queries?source=youtube_search&query=how to make a website&access_token=12345abcde ``` {% endtab %} {% tab title="PHP" %} ```php 'youtube_search', 'query' => 'how to make a website' ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "https://realtime.oxylabs.io/v1/queries"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params)); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_USERPWD, "USERNAME" .
