一. 问题：
在写调用谷歌翻译接口的脚本时，老是报错，我使用的的是googletrans这个模块中Translator的translate方法，程序运行以后会报访问超时错误:
Traceback (most recent call last): File "E:/PycharmProjects/MyProject/Translate/translate_test.py", line 3, in <module> result=translator.translate('안녕하세요.') File "D:\python3\lib\site-packages\googletrans\client.py", line 182, in translate data = self._translate(text, dest, src, kwargs) File "D:\python3\lib\site-packages\googletrans\client.py", line 78, in _translate token = self.token_acquirer.do(text) File "D:\python3\lib\site-packages\googletrans\gtoken.py", line 194, in do self._update() File "D:\python3\lib\site-packages\googletrans\gtoken.py", line 54, in _update r = self.client.get(self.host) File "D:\python3\lib\site-packages\httpx\_client.py", line 763, in get timeout=timeout, File "D:\python3\lib\site-packages\httpx\_client.py", line 601, in request request, auth=auth, allow_redirects=allow_redirects, timeout=timeout, File "D:\python3\lib\site-packages\httpx\_client.py", line 621, in send request, auth=auth, timeout=timeout, allow_redirects=allow_redirects, File "D:\python3\lib\site-packages\httpx\_client.py", line 648, in send_handling_redirects request, auth=auth, timeout=timeout, history=history File "D:\python3\lib\site-packages\httpx\_client.py", line 684, in send_handling_auth response = self.send_single_request(request, timeout) File "D:\python3\lib\site-packages\httpx\_client.py", line 719, in send_single_request timeout=timeout.as_dict(), File "D:\python3\lib\site-packages\httpcore\_sync\connection_pool.py", line 153, in request method, url, headers=headers, stream=stream, timeout=timeout File "D:\python3\lib\site-packages\httpcore\_sync\connection.py", line 65, in request self.socket = self._open_socket(timeout) File "D:\python3\lib\site-packages\httpcore\_sync\connection.py", line 86, in _open_socket hostname, port, ssl_context, timeout File "D:\python3\lib\site-packages\httpcore\_backends\sync.py", line 139, in open_tcp_stream return SyncSocketStream(sock=sock) File "D:\python3\lib\contextlib.py", line 130, in __exit__ self.gen.throw(type, value, traceback) File "D:\python3\lib\site-packages\httpcore\_exceptions.py", line 12, in map_exceptions raise to_exc(exc) from None httpcore._exceptions.ConnectTimeout: timed out
二. 解决方法：
1.寻找解决方法
经过多方资料查找，最后才知道google翻译对接口进行了更新，之前用的googletrans已经不能用了。但是网上大神已经开发出了新的方法
https://github.com/lushan88a/google_trans_new
在此道一声感谢！
2.使用解决方法
在cmd中输入以下指令即可。
pip install google_trans_new
三. 代码（优化）

四. 运行结果
五. 总结
本篇首先解决了调用googletrans模块的报错问题，然后使用新的google翻译模块编写了代码，并且解决了我这篇文章中翻译文本长度不能大于5000的问题。
