1.拿到第一個(gè)用戶名、鏈接以及include參數(shù)（user_url）

start_user = 'gui-mu-zhi'
user_url = 'https://www.zhihu.com/api/v4/members/{user}?include={include}'
user_query = 'allow_message,is_followed,is_following,is_org,is_blocking,employments,answer_count,follower_count,articles_count,gender,badge[?(type=best_answerer)].topics'

2.拿到粉絲鏈接以及include參數(shù)

follows_url = 'https://www.zhihu.com/api/v4/members/{user}/followers?include={include}&offset={offset}t&limit={limit}'
follows_query = 'data[*].answer_count,articles_count,gender,follower_count,is_followed,is_following,badge[?(type=best_answerer)].topics'

3.修改初始請求，返回用戶和粉絲的請求，通過format方法將參數(shù)傳遞進(jìn)去，分別回調(diào)解析用戶函數(shù)和解析粉絲函數(shù)

    def start_requests(self):
        yield Request(self.user_url.format(user=self.start_user, include=self.user_query), self.parse_user)
        yield Request(self.follows_url.format(user=self.start_user, include=self.follows_query, offset=0, limit=20), self.parse_follow)

4.解析用戶，獲取內(nèi)容

    def parse_user(self, response):
        # 將拿到的數(shù)據(jù)轉(zhuǎn)成json格式
        result = json.loads(response.text)
        # 將Item實(shí)例化對象
        item = ZhihuItem()
        # 遍歷item里面的fields
        for filed in item.fields:
            # 判斷filed是否在返回結(jié)果的keys中
            if filed in result.keys():
                # 將返回結(jié)果傳入item當(dāng)中
                item[filed] = result.get(filed)
        yield item
        # 返回請求粉絲鏈接將剛拿到的粉絲用戶里面的url_token還有include傳進(jìn)去  回調(diào)到解析粉絲函數(shù)當(dāng)中
        yield Request(self.follows_url.format(user=result.get('url_token'), include=self.follows_query, offset=0, limit=20), self.parse_follow)

5.# 解析粉絲列表

    def parse_follow(self, response):
        # 將返回結(jié)果轉(zhuǎn)成json格式
        results = json.loads(response.text)
        # 判斷'data'是否在在返回結(jié)果的keys里面
        if 'data' in results.keys():
            # 如果在  遍歷data數(shù)據(jù)
            for result in results.get('data'):
                # 返回請求用戶函數(shù)當(dāng)中 再解析存儲數(shù)據(jù)
                yield Request(self.user_url.format(user=result.get('url_token'), include=self.user_query), callback=self.parse_user)
        # 判斷paging是否在keys中并且當(dāng)中的is_end參數(shù)值是否為False（判斷是否是最后一頁）
        if 'paging' in results.keys() and results.get('paging').get('is_end') == False:
            # 拿到下一頁鏈接
            next_page = results.get('paging').get('next')
            # 返回請求下一頁  回調(diào)繼續(xù)解析粉絲
            yield Request(
                next_page,
                self.parse_follow,
            )
