Youtube 视频标题 API v3 没有 API 键？
Youtube Video title with API v3 without API key?
是否可以使用带有 API v3 的视频 ID 而无需 API 密钥来获取视频标题？我在 API 文档中找不到任何信息或获取标题的示例。
要获取视频标题，您将需要一个API密钥，并且您需要向以下地址发出请求：
https://www.googleapis.com/youtube/v3/videos?part=snippet&id={COMMA_DELIMITED_LIST_OF_IDS}&key={YOUR_API_KEY}
在返回的数据包中，标题将位于 items.snippet.title
如果没有 API 键，您将无法检索 任何 API 数据；所有 API 请求都在配额系统上，密钥用于确定向您的应用程序的每日限额收取多少费用。但是，像上面这样的调用非常便宜；总共有 3 个单元（2 个用于代码片段，1 个用于请求本身）。由于您每天获得 50,000,000 个单位，并且可以为同样的 3 个单位检索最多 50 个片段，因此使用 API 键并不是什么负担。
不需要API键
要获取视频标题，您 不需要 需要一个 API 密钥，并且您需要向以下地址发出请求：
https://noembed.com/embed?url=https://www.youtube.com/watch?v=dQw4w9WgXcQ
为您需要的视频更改 YouTube URL。
它也适用于 Vimeo 和许多其他 supported sites 以及 URL，例如：
https://noembed.com/embed?url=https://vimeo.com/45196609
详情
如果您直接使用 API，则在没有 API 密钥的情况下，无法使用带有 API v3 的视频 ID 获取视频标题。 YouTube 数据 API v2 已弃用（参见：YouTube Data API v2 Deprecation: Frequently Asked Questions) and currently the YouTube API doesn't support oEmbed with JSONP as it should (see Issue 4329: oEmbed callback for JSONP）。
但幸运的是，有 Noembed 服务可以让您使用 JSONP 而无需 API 密钥获取 YouTube 视频的标题（和其他数据）。
演示
这是一个简单的演示，可以使用 jQuery 获得标题：
var id = 'dQw4w9WgXcQ';
var url = 'https://www.youtube.com/watch?v=' + id;
$.getJSON('https://noembed.com/embed',
{format: 'json', url: url}, function (data) {
alert(data.title);
});
参见 JS Bin 上的 DEMO。
另请参阅这些问题：
这正是oEmbed协议的意思。
oEmbed is a format for allowing an embedded representation of a URL on
third party sites. The simple API allows a website to display embedded
content (such as photos or videos) when a user posts a link to that
resource, without having to parse the resource directly.

是的，你可以没有任何API只是请求和re模块
Python中的代码：
import requests,re
video_url = "https://www.youtube.com/watch?v=2i2khp_npdE"
response = requests.get(video_url).text
title = re.findall(r'"title":"[^>]*",',response)[0].split(',')[0][9:-1]
print("\n[+] Video Title: {}".format(title))
输出：
[+] 视频标题：Alan Walker - 唱歌让我入睡
是的，有可能。
我对 excellent Porto's answer here 做了一些修改，并在 Python 上写了这个片段：
import urllib, urllib.request, json
input = "C:\urls.txt"
output = "C:\tracks.csv"
urls=[line.strip() for line in open(input)]
for url in urls:
ID = url.split('=')
VideoID = ID[1]
params = {"format": "json", "url": "https://www.youtube.com/watch?v=%s" % VideoID}
url = "https://www.youtube.com/oembed"
query_string = urllib.parse.urlencode(params)
url = url + "?" + query_string
with urllib.request.urlopen(url) as response:
response_text = response.read()
try:
data = json.loads(response_text.decode())
except ValueError as e:
continue # skip faulty url
if data is not None:
author = data['author_name'].split(' - ')
author = author[0].rstrip()
f = open(output, "a", encoding='utf-8')
print(author, ',', data['title'], sep="", file=f)
它选择一个包含 Youtube URL 列表的文本文件：
https://www.youtube.com/watch?v=F_Vfgdfgg
https://www.youtube.com/watch?v=RndfgdfN8

和 returns 具有 Artist-Title 对的 CSV 文件：
Beyonce,Pretty hurts
Justin Timberlake,Cry me a river
