从python中的发布请求中解析数据

Question

我正在从网址的发布请求中获取此数据，解析此数据的最佳方法是什么？我需要的只是变量“ data”中的内容：

Answer 1

最简单的方法是使用正则表达式强行进行解析。将表达式读入字符串，然后对字符串进行正则表达式搜索以获取数据。这应该工作：

import re
with open('/tmp/jsdata','r') as jsd:
    datastr = jsd.read().replace('\n','')
expr = '(\"data\"\:.+?\]\])'    # the '?' at the end is to ensure non-greedy matching
data = re.search(expr, datastr)
print(data[0])    # the extracted data
