解决Antropic无法访问问题解决

1. 问题描述

通过Anthropic调用大模型，返回Error code: 403 - {'error': {'type': 'forbidden', 'message': 'Request not allowed'}}

2.原因分析

在开启vpn的情况下，通过发送post请求可以正常调用，通过Anthropic无法调用，可能是因为访问环境引起的，需要配置代理

3. 具体实现

custom_httpx_client = httpx.Client(
    transport=httpx.HTTPTransport(
        proxy=httpx.Proxy(
            url="http://your_proxy_address:port"
        )
    ),
    timeout=30.0
)


# 初始化Anthropic客户端
client = Anthropic(
    api_key="your-api-key",
    http_client=custom_httpx_client,
)

# 发送请求
response = client.messages.create(
    model="claude-3-7-sonnet-20250219",
    max_tokens=1024,
    messages=[
        {
            "role": "user",
            "content": "hello?"
        }
    ]
)

print(response.content)
