解决编码方式之间的转换时的报错

1.在使用python2.7做一些就接口测试时，会出现编码报错的问题：

 1 Traceback (most recent call last):
 2   File "E:/proto_code/Roshan-01-microscript-proto_test-master-src/src/run_all_case.py", line 31, in <module>
 3     runner.run(all_case())
 4   File "E:\proto_code\Roshan-01-microscript-proto_test-master-src\src\comment\HTMLTestRunner.py", line 746, in run

20   File "D:\Program Files (x86)\python2.7\lib\unittest\case.py", line 370, in run
21     result.stopTest(self)
22   File "E:\proto_code\Roshan-01-microscript-proto_test-master-src\src\comment\HTMLTestRunner.py", line 670, in stopTest
23     self.complete_output()
24   File "E:\proto_code\Roshan-01-microscript-proto_test-master-src\src\comment\HTMLTestRunner.py", line 645, in complete_output
25     return self.outputBuffer.getvalue()
26   File "D:\Program Files (x86)\python2.7\lib\StringIO.py", line 271, in getvalue
27     self.buf += ''.join(self.buflist)
28 UnicodeDecodeError: 'ascii' codec can't decode byte 0xcd in position 0: ordinal not in range(128)

 

在解决问题的探寻查询网上博客，发现很多人在说这是编码的问题：“Python在进行编码方式之间的转换时，会将 unicode 作为“中间编码”，但 unicode 最大只有 128 那么长，所以这里当尝试将 ascii 编码字符串转换成"中间编码" unicode 时由于超出了其范围，就报出了如上错误。”

同时网上的很多解决方法是在python文件的前面加上如下代码：

1 import sys
2 defaultencoding = 'utf-8'
3 if sys.getdefaultencoding() != defaultencoding:
4 reload(sys)
5 sys.setdefaultencoding(defaultencoding)

 

经试验发现，这种方法仅适用于python2.7，在python3中不适用，因为python3已经取消了reload，而在对于编码方法做了很大的调整

如果仍以下错误：

UnicodeDecodeError: 'utf8' codec can't decode byte 0xcd in position 0: invalid continuation byte

只需要将 defaultencoding 改为：GBK

import sys  
defaultencoding = 'gbk'
if sys.getdefaultencoding() != defaultencoding:
    reload(sys)
    sys.setdefaultencoding(defaultencoding)

 

2.在做接口测试时，发现有些入参中文是这样式的：2023%E4%B8%AD%E5%9B%BD%E7%89%9B%E9%80%BC，咋办？

import urllib

ch='2023中国牛逼'
ch_1=urllib.parse.quote(ch)
print('转义前：{}，转义后{}'.format(ch,ch_1))

print——转义前：2023中国牛逼，转义后:2023%E4%B8%AD%E5%9B%BD%E7%89%9B%E9%80%BC
