|
||
BASE_URL = "https://newsapi.org/v2/"
|
||
|
||
# 社交媒体API
|
||
TWITTER_BEARER_TOKEN = "your_twitter_token"
|
||
TWITTER_API_V2 = "https://api.twitter.com/2/"
|
||
|
||
# 金融数据API
|
||
ALPHA_VANTAGE_KEY = "your_alphavantage_key"
|
||
AV_BASE_URL = "https://www.alphavantage.co/query"
|
||
```
|
||
|
||
#### API调用示例
|
||
```python
|
||
import requests
|
||
import feedparser
|
||
from datetime import datetime
|
||
|
||
class SimpleSearchEngine:

||
def __init__(self):
|
||
self.news_api_key = "YOUR_KEY"
|
||
self.rss_sources = {
|
||
"finance": [
|
||
"https://feeds.bloomberg.com/markets/news.rss",
|
||
"https://feeds.reuters.com/reuters/businessNews"
|
||
],
|
||
"ai_software": [
|
||
"https://ai.googleblog.com/feeds/posts/default",
|
||
"https://techcrunch.com/feed/"
|
||
]
|
||
}
|
||
|
||
def search_by_industry(self, keywords, industry, language="en"):
|
||
results = []
|
||
|
||
# RSS搜索
|
||
for rss_url in self.rss_sources.get(industry, []):
|
||
feed = feedparser.parse(rss_url)
|
||
for entry in feed.entries:
|
||
if any(keyword.lower() in entry.title.lower() for keyword in keywords):
|
||
results.append({
|
||
'title': entry.title,
|
||
'link': entry.link,
|
||
'published': entry.published,
|
||
'source': rss_url
|
||
})
|
||
|
||
# NewsAPI搜索
|
||
if language == "en":
|
||
news_results = self.search_newsapi(keywords, industry)
|
||
results.extend(news_results)
|
||
|
||
return results
|
||
|
||
