我有这个生成yaml数据的脚本。我需要它来生成等效的json数据。
代码是这样的：
def main(argv):
global top
global version
global package
librivox_rest_url = 'unknown'
app_image_url = 'unknown'
password = 'XXXXXXX'
try:
opts, args = getopt.getopt(argv,"hl:t:v:k:p:i:",["url=","top=","version=","package=","password=","image_url="])
except getopt.GetoptError:
print 'make_hiera_data_from_librivox_api.py -l <librvox url> [-t <top>] [-v <version>] [-p <password>]'
sys.exit(2)
for opt, arg in opts:
if opt == '-h':
usage ( 'Help called' )
sys.exit(0)
elif opt in ("-l", "--url"):
librivox_rest_url = arg
elif opt in ("-t", "--top"):
top = arg
elif opt in ("-v", "--version"):
version = arg
elif opt in ("-p", "--password"):
password = arg
elif opt in ("-k", "--package"):
password = arg
elif opt in ("-i", "--image_url"):
app_image_url = arg
if ( librivox_rest_url == 'unknown' ):
usage ("Please specify a librivox api url")
sys.exit (1)
if ( app_image_url == 'unknown' ):
usage ("Please specify the app image url")
sys.exit (1)
parsed = json.loads(requests.get(librivox_rest_url).text)
book_key = parsed['books'].keys()[0]
apptitle = parsed['books'][book_key]['title']
app_image_url = app_image_url
app_zip_url = parsed['books'][book_key]['url_zip_file']
description = parsed['books'][book_key]['description']
yaml_version = """---

print json.dumps( yaml_version, sort_keys=True, indent=2)
当我运行脚本时，我得到这个输出，其中json数据只是一个很长的行。我做错了什么？

生成yaml：
import yaml
data = {...} # python datastructure
yaml.dump(data, default_flow_style=False) # second parameter specifies block style yaml.
生成很好的缩进json：
print json.dumps(data, indent=4)
如果你有yaml并想要json：
print json.dumps(yaml.load(...), indent=4)
