上一篇博客：Flask之手搓bootstrap翻页-CSDN博客 里，对 OMDb API - The Open Movie Database 的搜索，只能使用英文，才能搜索出电影信息，如果使用中文，是搜索不到结果的。这里就需要使用翻译，把中文电影名翻译成英文电影名。
这里使用百度翻译，百度翻译量少的话是免费的，百度翻译开放平台，而且有python的示例代码，可以直接照抄。

# This code shows an example of text translation from English to Simplified-Chinese.
# This code runs on Python 2.7.x and Python 3.x.

from_lang = 'en'
to_lang = 'zh'
endpoint = 'http://api.fanyi.baidu.com'
path = '/api/trans/vip/translate'
url = endpoint + path
query = 'Hello World! This is 1st paragraph.\nThis is 2nd paragraph.'
# Generate salt and sign
def make_md5(s, encoding='utf-8'):
return md5(s.encode(encoding)).hexdigest()
salt = random.randint(32768, 65536)
sign = make_md5(appid + query + str(salt) + appkey)
# Build request
headers = {'Content-Type': 'application/x-www-form-urlencoded'}
payload = {'appid': appid, 'q': query, 'from': from_lang, 'to': to_lang, 'salt': salt, 'sign': sign}
# Send request
r = requests.post(url, params=payload, headers=headers)
result = r.json()
# Show response
print(json.dumps(result, indent=4, ensure_ascii=False))只需要在搜索路由里，将form表单传递过来的中文搜索词翻译成英文即可。如果是英文，那就让它再翻译一遍，一般是没有变化。
详细代码如下。
