    之前学过python的爬虫技术,现在回顾一下看看还会不会,果然有坑。

    先爬取了微博评论网友的id
    代码如下

    import requests
    url = 'https://m.weibo.cn/api/comments/show?id=4188633986790962&page=6
    h = requests.get(url)
    print(h.json()['data']['data'][0]['user']['id'])

    执行的时候报错
    Traceback (most recent call last):
    File "e:/personal/vscode/pameinv.py", line 9, in <module>
    print(a())
    File "e:/personal/vscode/pameinv.py", line 8, in a
    return html.json()
    File "D:\python\Python37\lib\site-packages\requests\models.py", line 897, in json
    return complexjson.loads(self.text, **kwargs)
    File "D:\python\Python37\lib\json__init__.py", line 348, in loads
    return _default_decoder.decode(s)
    File "D:\python\Python37\lib\json\decoder.py", line 337, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
    File "D:\python\Python37\lib\json\decoder.py", line 355, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
    json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
    于是开始各种调试 最后换了一个地址行了,可能是微博的api不让调用了
    于是修改了一下程序

    import requests
    url = 'http://www.yy.com/api/yyue-spot-news'
    h = requests.get(url)
    for j in range(len(h.json()['data'])):
    print(h.json()['data'][j]['id']) #这里有缩进

    print里的内容是根据网页里的相应信息而定的
    python爬取主播信息

    最后运行了一下 成功显示了主播的id
