json - JSONDecodeError：期望值：json（）的第1行第1列（char 0）在 Python3 上

Question

我正在尝试将在 Python2 上运行良好的代码移植到 Python3。我试图修复一些错误，但现在它与 json() 在 . 代码如下所示

resp = requests.get("https://status.github.com/api/status.json")
print(resp.ok)          
print(resp.status_code) 
print(resp.headers['content-type'])
print(resp)
x = resp.json()

调试结果如下

> True 200 text/html; charset=utf-8 <Response [200]>
> --------------------------------------------------------------------------- JSONDecodeError                           Traceback (most recent call

>       4 print(resp.headers['content-type'])
>       5 print(resp)

JSONDecodeError：期望值：第 1 行第 1 列（字符 0）

resp = requests.get("https://status.github.com/api/status.json")         
print(resp.headers['content-type'])

文本/html；字符集=utf-8

用于resp.headers['content-type']查找链接 web 是text/html.

因此 resp.json() 不适用于这种格式。也许你想试试 Beautifulsoup。
