查過自己電腦網(wǎng)絡配置中沒有設置代理。

最后，將url = 'http://www.baidu.com'?改成?url =?'https://www.baidu.com'，?使用以上兩個代理地址測試都能成功，結果：200

-----

換了一個新的代理： 'http': '47.93.36.195:8118'?

url = 'http://www.baidu.com'?

多次運行，返回狀態(tài)有200,503，還有ChunkedEncodingError

由此可見，ChunkedEncodingError錯誤并不是代理問題，為穩(wěn)定，還是將url改為https為好。
