修改代码 def get_user_info(self, selector): """ 获取用户昵称、微博数、关注数、粉丝数 """ try: # print('------Get user nickname, microblog_num, following, fans------') self.get_nickname() # get user's name user_info = selector.xpath("//div[@class='tip2']/*/text()") self.microblog_num = int(user_info[0][3: -1]) print(u'微博数: ', self.microblog_num) self.following = int(user_info[1][3: -1]) print(u'关注数: ', self.following) self.fans = int(user_info[2][3: -1]) print(u'粉丝数: ', self.fans) print('*' * 100) except Exception as e: print('Error: ', e) traceback.print_exc()

这段代码的问题在于没有返回用户信息，修改后的代码如下：

def get_user_info(self, selector):
    """ 获取用户昵称、微博数、关注数、粉丝数 """
    try:
        # print('------Get user nickname, microblog_num, following, fans------')
        self.get_nickname()  # get user's name
        user_info = selector.xpath("//div[@class='tip2']/*/text()")
        self.microblog_num = int(user_info[0][3: -1])
        print(u'微博数: ', self.microblog_num)
        self.following = int(user_info[1][3: -1])
        print(u'关注数: ', self.following)
        self.fans = int(user_info[2][3: -1])
        print(u'粉丝数: ', self.fans)
        print('*' * 100)
        return {"nickname": self.username, "microblog_num": self.microblog_num, "following": self.following, "fans": self.fans}
    except Exception as e:
        print('Error: ', e)
        traceback.print_exc()

现在这个函数会返回一个字典，包含用户昵称、微博数、关注数和粉丝数。
