使用python读取URL时出错，如何修复

Question

import requests
data = 'C:\Users\abc\Desktop\dashboard\dom.html'
response = requests.get(data)
print (response.json())

错误接收为

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

我曾尝试将data = (r'C:\Users\abc\Desktop\dashboard\dom.html')给出的错误设置为

requests.exceptions.InvalidSchema: No connection adapters were found for url

Answer 1

只需更改斜杠的类型。将其替换为此/。你的代码将变成：

import requests
data = 'C:/Users/abc/Desktop/dashboard/dom.html'
response = requests.get(data)
print (response.json())

Answer 2

您不能在请求中读取本地文件，默认情况下只能使用http或https协议。但是，您可以编写自定义适配器，但最好的方法是正常读取文件，而不是使用请求。

with open("file.json") as fh:
    print(json.load(fh))
