Answer 1

可能是因为网页版本的百度翻译防爬所致，换用手机版本的百度翻译暂时可行。思路仍是伪造请求并获得响应，注意此时返回的响应结构。

该方法可能不久也会被防爬，可以考虑注册百度开发者账号解决，或详细研究请求中的token

1. def translateBaidu(text):

2. content=text

3. url = "http://fanyi.baidu.com/basetrans"

4.  

5. data = {

6. "query":content,

7. "from":"jp",

8. "to":"zh",

9. }

10.  

11. headers = {

12. "User-Agent":"Mozilla/5.0 (Linux; Android 5.1.1; Nexus 6 Build/LYZ28E) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Mobile Safari/537.36",

13. }

14.  

15. response = requests.post(url,data = data,headers = headers)

16. print(response.json()['trans'][0]['dst'])
