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。

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。

把数字放前面，反而可以搜到，不知道翻译是咋翻译的。
