Two real-life solutions to value error reporting and encoding error reporting in Python when processing JSON
Two real-life solutions to value error reporting and encoding error reporting in Python when processing JSON
1、ValueError: Invalid control character at: line 1 column 8363 (char 8362)
使用json.loads(json_data)时，出现：
ValueError: Invalid control character at: line 1 column 8363 (char 8362)
出现错误的原因是字符串中包含了回车符（\r）或者换行符（\n）
解决方法：
(1)对这些字符转义：
json_data = json_data.replace('\r', '\\r').replace('\n', '\\n')
(2)使用关键字strict:
json.loads(json_data, strict=False)
strict默认是True,它将严格控制内部字符串，将其设置为False,便可以允许你\n \r。
2、UnicodeEncodeError: ascii codec can't encode错误
在windows下写的python脚本，放到linux下运行，直接报：
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-11: ordinal not in range(128)
解决方法：
（1）临时解决方法：
在代码前加入：
import sys
reload(sys)
sys.setdefaultencoding('utf8')
（2）一劳永逸：
在Python的lib\site-packages文件夹下新建一个sitecustomize.py，内容如下：
# encoding=utf8
import sys
reload(sys)
sys.setdefaultencoding('utf8')
这样的话，系统在Python启动的时候，自行调用该文件，设置系统的默认编码。
