提问by Apache
How can data can be sent to the server?
如何将数据发送到服务器？
For example, I have retrieve MAC address, so I want send to the server (e.g. http://211.21.24.43:8080/data?mac=00-0C-F1-56-98-AD)
例如，我已经检索到 MAC 地址，所以我想发送到服务器（例如http://211.21.24.43:8080/data?mac=00-0C-F1-56-98-AD）
I found this snippet on the Internet:
我在互联网上找到了这个片段：
from urllib2 import Request, urlopen
from binascii import b2a_base64
def b64open(url, postdata):
req = Request(url, b2a_base64(postdata), headers={'Content-Transfer-Encoding': 'base64'})
return urlopen(req)
conn = b64open("http://211.21.24.43:8080/data","mac=00-0C-F1-56-98-AD")
but when I run it, I get:
但是当我运行它时，我得到：
File "send2.py", line 8
SyntaxError: Non-ASCII character '\xc3' in file send2.py on line 8, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
Can anyone help me send data to the server?

You have copied and pasted code with non-ASCII characters. You have an \xc3character on line 8.
您已使用非 ASCII 字符复制和粘贴代码。您\xc3在第 8 行有一个字符。
回答by Rodrigo Pinho Pereira de Souza
put the encoding at the top of .py file
将编码放在 .py 文件的顶部
example:
例子：
#!/usr/bin/env python
#coding: utf8
import os
...
This probably happened because you copied/pasted some unicode character that is not visible in your text editor.
这可能是因为您复制/粘贴了一些在文本编辑器中不可见的 unicode 字符。

This solution works for me on Ubuntu.
这个解决方案在 Ubuntu 上对我有用。
Add the following statement right at the beginning, before all import statements.
在开头添加以下语句，在所有导入语句之前。
# -*- coding: utf-8 -*-`
Similar approach for errors with the term '\xe2'.
术语 错误的类似方法'\xe2'。

Incorrect characters are probably "comma", or "quotes" on line 8. It probably occurred during the "Ctrl + C", "Ctrl + V". ;) You can try rewrite these characters manually.
不正确的字符可能是第 8 行的“逗号”或“引号”。它可能发生在“Ctrl + C”、“Ctrl + V”期间。;) 您可以尝试手动重写这些字符。
