Question

源代码

from langchain.tools import YouTubeSearchTool,Tool
proxies = {'HTTP': 'HTTP://127.0.0.1:7890', 'HTTPS': 'HTTP://127.0.0.1:7890'}
tool = YouTubeSearchTool(proxies ='http://localhost:7890')
tool.run("langchain")

出现错误：
requests.exceptions.ProxyError: HTTPSConnectionPool(host='youtube.com', port=443): Max retries exceeded with url: /results?search_query=langchain (Caused by ProxyError('Unable to connect to proxy', SSLError(SSLZeroReturnError(6, 'TLS/SSL connection has been closed (EOF) (_ssl.c:1135)'))))

同样的proxies参数下可以连接到hugging face

ping不通youtube.com
但是在网页上打得开

错误详情：

urllib3.exceptions.SSLError: TLS/SSL connection has been closed (EOF) (_ssl.c:1135)

The above exception was the direct cause of the following exception:

urllib3.exceptions.ProxyError: ('Unable to connect to proxy', SSLError(SSLZeroReturnError(6, 'TLS/SSL connection has been closed (EOF) (_ssl.c:1135)')))

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\1\.conda\envs\prompt02\lib\site-packages\requests\adapters.py", line 670, in send
    resp = conn.urlopen(

    retries = retries.increment(

During handling of the above exception, another exception occurred:

根据错误提示，请求无法连接代理，引起这个问题大概率是代理设置或者代理配置的问题。可以尝试以下几种解决方法：

1. 检查代理配置是否正确：确保代理服务器的地址和端口号正确，并且代理服务器是可用的。

2. 使用不同的代理方式：尝试使用其他代理方式，比如socks代理或者其他http代理，看是否能够解决问题。

3. 确保网络连接正常：检查网络连接是否正常，可以尝试ping其他网站或者使用浏览器打开其他网站确认网络连接是否通畅。

4. 可能是对方网站反爬机制导致：有一些网站会检测到代理IP，从而导致无法访问。可以尝试更换代理IP或者使用更高匿名性的代理IP。 案例：

import requests
proxies = {
    'http': 'http://127.0.0.1:7890',
    'https': 'http://127.0.0.1:7890'
}
url = "https://www.baidu.com/"
try:
    response = requests.get(url, proxies=proxies)
    print(response.text)
except requests.exceptions.ProxyError as e:
    print("ProxyError:", e)
except requests.exceptions.SSLError as e:
    print("SSLError:", e)
except requests.exceptions.ConnectionError as e:
    print("ConnectionError:", e)

通过以上方法可以尝试解决请求无法连接代理的问题。希望对您有所帮助。
