根因分析

服务器发送响应数据时间过长，可能是由于负载过大或网络缓慢。

English

The server is taking too long to send the response data, possibly due to large payload or slow network.

解决方案

  1. 85% 成功率 Increase the read timeout value 
    client = httpx.Client(timeout=httpx.Timeout(60.0, read=120.0))
response = client.get('https://api.example.com/v1/large-data')
  2. 90% 成功率 Use streaming to process data incrementally 
    with httpx.stream('GET', 'https://api.example.com/v1/large-data') as response:
    for chunk in response.iter_bytes():
        process(chunk)

无效尝试

常见但无效的做法:

  1. Reducing the timeout value to force faster failures 80% 失败

    A shorter timeout does not help retrieve the data; it only fails faster.

  2. Using stream=False (default) without adjustment 70% 失败

    The default behavior still waits for the entire response; streaming is needed.
