Question

我正在尝试使用python的yaml模块将字符串解析为字典。当值中包含“：”时，我会遇到异常。这是我的示例代码

import yaml

input = '''{"method":"Send", "buf":{"html":"<html><body><div style=\"color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt\"><ul><li>Sample message</li><li>Parse it<br></li></ul></div></body></html>","text":"\t* Sample message\n\t* Parse it\n"}} '''
yaml.load(input)

我收到以下异常

Traceback (most recent call last):

    yaml.load(input)
  File "/usr/lib/python2.4/site-packages/yaml/__init__.py", line 58, in load

有没有解决方法呢？

这有效

import yaml

input = r'{"method":"Send", "buf":{"html":"<html><body><div style=\"color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt\"><ul><li>Sample message</li><li>Parse it<br></li></ul></div></body></html>","text":"\t* Sample message\n\t* Parse it\n"}} '
print yaml.load(input)

使用yaml将json响应解析为dict
