这是多次实验中成功与不成功结果中构造的url
1）得到想要结果，所构造的url中keyword=******与下一参数间没有&链接
2）同样的keyword=%E8%A1%97%E6%8B%8D,参用不同的方式：‘https://www.toutiao.com/api/search/content/?keyword=%E8%A1%97%E6%8B%8D’+urlencode(params)
requests.get(‘https://www.toutiao.com/api/search/content/?’，params=params)
得到的url结果是不一样的，前一个的keyword不变，还是%E8%A1%97%E6%8B%8D,后一种方式得到的keyword变成了%25E8%25A1%2597%25E6%258B%258D
