学爬虫的第一个问题

requests遇到的错误

1，443错误 requests05

```python
port=443): Max retries exceeded with url: 
/sug (Caused by NewConnectionError
('<urllib3.connection.VerifiedHTTPSConnection object 
at 0x0000000003ABF518>: Failed to establish a new 
connection: [Errno 11004] getaddrinfo failed',))

Process finished with exit code 1

**解决方法：从百度找了，只需要安装几个requests依赖包就可以
pip install cryptography
pip install pyOpenSSL
pip install certifi** 
然后又报错

```python
 for item in json_data['data']:
TypeError: string indices must be integers

这个错误意思是字符串的下标一定要是整数
原因是未把字符串转换为json对象 转换即可

将字符串转化为json对象

json_data = json.loads(json_data)
运行成功
